Last updated: August 19th 2026 —
We’ve comprehensively updated this guide to reflect the latest flight-search options, tools and differences across Google Flights, Skyscanner, KAYAK and Momondo.
Some of the most popular sites for comparing flights online are Google Flights, Skyscanner, Kayak, and Momondo. In fact, if you were to search for “Cheap flights”, you would find many of these services in the top ten results.
They each perform a similar function: searching hundreds of airlines and travel agents and returning the cheapest and most convenient options to the user.
However, each platform has specific strengths, pros, cons and weaknesses.
Google Flights is exceptionally fast and shows helpful matrices for flexible dates and historical price graphs. Skyscanner has powerful explore features and has outstanding coverage of budget carriers. Kayak offers granular filters and excellent global coverage. Momondo also has comprehensive carrier coverage with handy flight insight tools.
Each search engine can surface different pricing and fares for the same flight itinerary. That makes it wise to compare multiple aggregators to be sure you have found the best available fare.
In this guide, we compare KAYAK, Skyscanner, Google Flights and momondo by looking at their:
- flight search capabilities;
- flexible-date tools;
- destination discovery;
- price tracking;
- multi-city search;
- filtering;
- booking options;
- strengths;
- weaknesses;
If your main question is which comparison site actually finds the cheapest fares, we have tested that separately in our flight comparison price study.
This guide focuses on how the four search engines differ and which features are most useful depending on your search intent.
KAYAK vs Skyscanner vs Google Flights vs Momondo: Quick Verdict
There isn’t one overall winner. Each has unique features that can help depending on your needs.
Our assessment is:
Google Flights: Best for quickly understanding average fare prices and comparing alternative dates.
Skyscanner: Excellent for travellers who are flexible about where or when they travel.
KAYAK: Strong all-rounder with particularly granular smart filtering, and showing hacker fares (i.e stitching flights together from different airlines on a single route).
momondo: Useful as an additional metasearch engine for broad fare comparison and finding options from lesser-known booking agents.
For travellers looking to find the lowest available fare for a particular route, our preferred advice is quite clear:
Don’t choose only one. Compare multiple flight search engines.
That is the principle behind FlightsFinder.com, which lets travellers compare leading flight search engines in one place.
What Is a Flight Comparison Website?
A flight comparison site is sometimes also known as a meta search engine, or flight aggregator.
They search the databases of tons of airlines and travel agents and return the cheapest, best and quickest options in one searchable interface.
Rather than selling you the ticket like a traditional travel agent or airline, they show you the offers and which company is selling them. When you select a flight price, you're redirected to the booking agent or airline to buy the ticket.
KAYAK claims it searches hundreds of travel sites simultaneously and up to 1000 travel sites and apps.
Skyscanner says it compares 1200 travel sources.
Momondo is owned by the same company behind Kayak. Surprisingly, even they can surface fares that Kayak doesn't.
Google Flights, which purchased ITA software, performs a similar comparison function, allowing travellers to search return, one-way, and multi-city itineraries and then be redirected to the relevant booking provider to complete their purchase.
Other flight search engines on the market that use a similar model include Cheapflights, Skiplagged, KIWI, Hopper and AviaSales / Jetradar.
1. Google Flights
Google Flights has become one of the most useful tools for exploring airfare prices.
They have a huge advantage over other search engines by being the default search engine on Google search results pages whenever anyone enters a flight search query.
Google Flights supports return, one-way and multi-city searches and provides an interactive calendar and price graph for comparing fares. Users can also filter results by specifying stops, airlines, and flight times.
Google Flights Explore Feature
This is arguably one of Google Flights’ strongest features.
Instead of repeatedly entering different cities to check prices, travellers can enter their arrival airport to ‘Anywhere’, and Google will display an interactive map of the world showing the cheapest places to fly to.
Users can then narrow down their options by selecting a weekend trip, a one-week or two-week trip, in any month of the coming year.
You can further refine your options by choosing the number of stops, whether you want direct flights or specific airlines, and by filtering by budget and flight duration.
Google Flights Flexible-Date Search
Google Flights provides a lightning-fast flexible-date price calendar that shows you prices over various travel dates.
Price calendar updates
A feature of its flexible date calendar is that prices update based on the filters you select.
For example, if you select direct flights only, the calendar shows only direct flight prices; if you select flights from a particular airline, the calendar shows only prices for that carrier.
Date grid
By clicking the date grid option, Google Flights generates a date grid calendar showing the cheapest departure and return dates, which you can adjust easily. The cheapest options are highlighted in green with an asterisk beside them.
Alternate airports
Google may also indicate when another nearby airport produces a cheaper itinerary.
This makes Google Flights especially effective at answering questions such as:
“Would leaving on Wednesday instead of Friday save me money?”
or:
“What happens if I travel a week later?”
rather than simply:
“What flights are available on these exact dates?”
They also have a handy feature that lets you enter up to 7 different departure airports and 7 different arrival airports to compare multiple flight routes at once.
Google Flights Price history
By clicking the View price history link, Google opens a price trend graph showing the price trend for your route over the last 60 days. It then indicates whether the dates you selected are low, typical, or high based on this history. This feature gives you a good idea of whether you found a good deal.
Google AI-Powered Flight Deals
A new feature on Google Flights is an AI-powered flight deal finder. Using natural language, you can type in the type of trip you're looking for, the duration, and any other requirements you need. Results load lightning fast, and it's an excellent way of discovering cheap destinations you may not have thought of before
Google Flights Price Tracking
Google Flights also lets users track fares for particular routes, dates or individual flights.
Google says travellers can track prices for particular dates and, in some cases, use an “Any dates” option when their schedule is flexible.
This can help when you have identified a trip but aren't ready to buy immediately.
Google Flights Filters
Google Flights provides the main filters most travellers need, including:
- stops;
- airlines;
- flight times;
- cabin class;
- and other itinerary characteristics.
The interface is relatively uncluttered, making it easy to eliminate unsuitable flights quickly.
Google Flights Multi-City Search
Google Flights supports:
- return journeys;
- one-way journeys;
- and multi-city journeys.
That makes it useful for more complicated itineraries such as:
London → New York → Miami → London
rather than a simple return ticket.
Google Flights Pros
Excellent date visualisation
The calendar and Price Graph make Google Flights particularly good for identifying whether changing your dates could reduce the fare.
Good AI natural language search deals
AI flight deals are a handy way to discover the best deals on the market using natural language queries.
Fast to explore
The interface makes it easy to change airports, dates, airlines, and other search parameters without restarting your entire search.
Strong filtering
You can quickly narrow flights by the criteria most travellers care about.
Useful fare tracking
Price tracking is integrated directly into the search process.
Google Flights Cons
Don't assume it shows the cheapest possible offer.
Like any individual flight search engine, Google Flights represents one view of the available market.
Another comparison engine may surface a cheaper booking provider or itinerary.
Not every displayed price is necessarily available.
Airline pricing changes continuously. Google notes that it updates displayed prices periodically.
Always confirm the live fare before booking as the price shown can sometimes be unbookable.
Sometimes features on other sites find deals Google does not.
Google Flights is outstanding to understand dates, schedules, and fare patterns, but highly price-sensitive travellers may still benefit from comparing its features with other comparison search engines. - i.e their proprietary price calendars and ‘search everywhere’ functions.
Google Flights Strengths
We particularly like Google Flights for:
- comparing dates;
- understanding price patterns;
- checking backup airports;
- researching schedules;
- filtering large sets of flights;
- uncluttered, ad-free design and interface.
Google Flights Weaknesses
Some of the biggest weaknesses include:
- Phantom fares: sometimes the flight advertised is no longer bookable upon click-through;
- Other search engines can find cheaper flights on occasion;
- They don't give much information on their booking partners - ie star ratings and feedback;
- You cannot check prices with checked bags within their filters, only a cabin bag;
- Many deals exist on other sites which are not found by AI flight deals;
- You cannot view price estimates in the calendar for multi-city flight searches.
- Even though they say you can enter up to 7 different departure/arrival airports, in reality the search engine can rarely handle such large queries.
2. Skyscanner
Skyscanner is one of the best-known flight comparison services and has traditionally been especially strong for flexible travellers.
Its tools are engineered not just around the question:
“How much is a flight to Paris on 12 September?”
but also questions such as:
“Where can I travel cheaply next month?”
That difference makes Skyscanner particularly useful during the inspiration and discovery stages of trip planning.
Skyscanner Everywhere Search
One of Skyscanner’s most distinctive tools is Everywhere Search.
Travellers can enter their departure airport and choose “Everywhere” as the destination.
Skyscanner then displays destination options, letting users explore where they can travel within their budget.
This is particularly useful when the traveller cares more about:
“Where can I go cheaply?”
than:
“How cheaply can I reach this particular destination?”
Skyscanner Whole Month Search
Skyscanner also has strong flexible-date functionality.
Its flexible-date tools let users compare prices throughout a whole month range rather than being restricted to a single departure and return date.
Skyscanner currently offers options including Whole Month and Cheapest Month searches.
This can be very effective for leisure travellers whose schedules allow them to move a holiday by several days.
Skyscanner Price Alerts
Skyscanner offers Price Alerts for travellers who are not ready to book.
Once you create an alert, Skyscanner monitors the fare and can notify you when the price changes.
This can be useful after you have narrowed your destination and approximate dates but are still deciding when to purchase.
Skyscanner Multi-City Flights
Skyscanner also supports multi-city searching.
This lets travellers build itineraries with several destinations instead of buying each trip separately.
Skyscanner Pros
Excellent destination discovery
Everywhere Search is extremely useful when destination flexibility matters more than travelling somewhere specific.
Strong flexible-date tools
Whole Month and Cheapest Month tools make it easy to investigate alternative dates.
Broad comparison
Skyscanner compares fares across major airlines and travel providers.
Price alerts
Travellers can monitor a route instead of repeatedly running the same manual search.
Skyscanner Cons
Flexible-date prices can be indicative rather than a guaranteed live fare.
Skyscanner explains that some prices used in flexible or discovery tools are based on recently found fares and may therefore differ once a full live search is performed.
That means a price displayed in an exploratory view should be treated as a useful guide, not a guaranteed booking price.
Cheapest does not automatically mean best.
Like other comparison engines, Skyscanner can present offers from different booking providers.
Travellers should check the provider, baggage terms, ticket conditions, and final checkout price before deciding based purely on the headline fare.
Another comparison engine may find something different.
Strong coverage does not mean identical coverage.
If finding the lowest possible fare matters, another search engine is still worthwhile.
Skyscanner Strengths
We particularly prefer Skyscanner for:
- flexible travellers;
- destination inspiration;
- whole-month searching;
- comparing broad travel possibilities;
- and travellers who know their budget but haven’t decided exactly where to go.
Skyscanner Weaknesses
Skyscanner has some downsides too:
- Sometimes the price shown cannot be booked - aka a phantom fare;
- People have reported difficulties post-booking with some of their lesser-known travel agent partners;
- Their prices can be beaten on occasion by other aggregators;
- When comparing flexible date options, you cannot check the duration of the advertised flight;
- Speed is slower than Google Flights.
3. KAYAK
KAYAK is another major travel metasearch platform and arguably offers one of the broadest sets of flight-search and travel-planning tools.
KAYAK says it searches hundreds of travel sites at once to compare options.
Its strength lies in combining standard flight search with tools for:
- flexible dates;
- price monitoring;
- destination discovery;
- backup airports;
- filtering;
- and fare analysis.
KAYAK Price Calendar
KAYAK’s Price Calendar is designed to make cheaper travel dates easier to spot at a glance.
KAYAK says the calendar uses historical and current pricing information to display fare differences by date.
It uses colour codes to show cheaper days to fly: green for the cheapest days, orange for average days, and red for the most expensive.
This gives KAYAK an advantage for flexible travellers, similar to Google Flights and Skyscanner.
KAYAK Price Alerts
KAYAK also provides Price Alerts.
Users can select a route and dates, and KAYAK monitors price changes and sends updates when fares move.
KAYAK Explore
For travellers who haven’t chosen a destination, KAYAK Explore provides a map-based discovery interface.
Users can specify criteria such as:
- origin;
- budget;
- travel period;
- trip type;
- stops;
- and flight duration.
KAYAK then displays potential destinations.
It displays a handy global map and lets users see at a glance the best prices from their chosen departure airport.
This puts it in broadly similar territory to Skyscanner’s Everywhere functionality, although the interfaces and presentation are different.
Nearby Airports
KAYAK also allows travellers to broaden searches using nearby airports.
Its own flight-search guidance recommends combining flexible dates with nearby airports when looking for lower fares.
This is particularly useful in places such as London, where travellers may realistically choose between several departure airports.
KAYAK Multi-City Search
KAYAK supports multi-city flight searching as part of its flight platform. Its help documentation specifically includes journeys involving more than one city.
KAYAK Pros
Excellent all-round search toolkit
KAYAK combines traditional flight comparison with:
- flexible dates;
- price calendars;
- nearby airports;
- alerts;
- Explore;
- and extensive filtering.
Particularly useful for detailed searching
Travellers who already know what they want can refine results rather than starting over.
Strong destination discovery
KAYAK Explore provides a visual alternative for travellers whose destination isn’t fixed.
Useful price-monitoring tools
Its alert system reduces the need to repeat searches.
KAYAK Cons
The number of tools can make the experience feel more complex.
Travellers who want a quick overview may find Google’s simpler presentation easier to digest.
This is primarily a matter of preference rather than a fundamental weakness.
KAYAK cannot guarantee that another engine won’t find a different fare
It searches an extremely broad range of travel sources, but you shouldn't assume any individual flight comparison platform represents every possible fare available elsewhere.
You still need to verify discovery prices.
KAYAK notes that prices displayed within Explore can be estimates based on recent searches and remain subject to availability and change.
KAYAK Strengths
We particularly like KAYAK for:
- detailed flight searching;
- travellers who enjoy using filters;
- comparing nearby dates and airports;
- price tracking;
- destination exploration;
- and those wanting a comprehensive set of search tools in one platform.
KAYAK Weaknesses
KAYAK downsides include:
- Can be beaten on price by other flight aggregators;
- Does not have reviews or star ratings of their booking partners;
- Less flexible search options than Skyscanner;
- Can show phantom fares on occasion, like all other metasearch engines;
- Slower loading than Google Flights;
- No price estimates on its calendar when searching for multi-city flights.
4. Momondo
Momondo is another established travel metasearch platform that compares flights across airlines and travel sites.
Its fundamental value is similar to KAYAK and Skyscanner:
It gives travellers another view of the airfare market.
That matters because different flight comparison websites can occasionally surface different booking combinations and providers.
Momondo Flight Search
Momondo searches and compares airfares across many airlines and travel websites.
Its interface allows travellers to search for:
- return;
- one-way;
- and multi-city itineraries.
Momondo Price Alerts
Momondo offers Price Alerts that allow travellers to monitor a particular flight search and receive notifications when prices change.
As with similar tools from KAYAK, Skyscanner and Google Flights, this is most useful when you know roughly where and when you want to travel but aren’t yet ready to book.
Momondo Multi-City Search
Momondo provides dedicated multi-city search functionality, allowing you to combine several flight sectors into the same search.
This can be useful for complicated holidays, open-jaw trips or travellers visiting several cities.
Momondo Pros
Another valuable source of comparison
The greatest reason to use momondo may be that it represents another major search of airline and travel-site fares.
Price alerts
Users can monitor fares without manually running the same search every day.
Multi-city functionality
More complicated trips can be searched without restricting the traveller to a simple return itinerary.
Broad provider comparison
Momondo searches across airlines and travel websites rather than restricting the traveller to one booking source.
Momondo Cons
Some functionality overlaps with KAYAK.
Travellers familiar with both platforms will find considerable overlap in the tools and general metasearch approach.
Less distinctive for date visualisation than Google Flights
For travellers primarily trying to understand how fares move across dates, we generally find Google’s visual date tools particularly intuitive.
Less distinctive for destination discovery than Skyscanner
Skyscanner’s Everywhere functionality is one of the clearest destination-discovery propositions among major flight comparison platforms.
That does not make momondo ineffective; it simply means its strongest reason for inclusion in a flight search may be the additional comparison coverage it provides.
Momondo Strengths
We particularly like momondo for:
- adding another major source to your fare comparison;
- searching lesser-known online travel agents;
- Flight insights tool lets you see fare history for your route;
- monitoring prices;
- handy price graph to locate cheaper alternate dates.
Momondo Weaknesses
Momondo has some drawbacks:
- May show less established agents with poorer customer service;
- Can be beaten on price by other aggregators;
- Does not have reviews or star ratings of their booking partners;
- Can show outdated fares;
- The price graph is based on historical searches, not live data, which can create inaccuracies and be misleading.
KAYAK vs Skyscanner vs Google Flights vs Momondo: Feature Comparison
Best for Flexible Dates: Google Flights, KAYAK or Skyscanner
All three provide strong tools, but they approach the problem differently.
Google Flights excels at visualising how changing departure and return dates affects fares through its calendar and Price Graph.
Skyscanner excels when flexibility is broader, particularly through Whole Month and Cheapest Month searches.
KAYAK combines nearby-date searching with its Price Calendar and wider flexible-date functionality.
Our verdict
For quickly comparing specific nearby dates:
Google Flights is particularly strong.
For broad month-level flexibility:
Skyscanner is particularly useful.
For travellers wanting flexible dates plotted on an interactive global map:
KAYAK is an excellent all-round option.
Best for Destination Inspiration
If you know you want to travel but haven’t chosen where, both Skyscanner, KAYAK and Google Flights offer particularly useful tools.
Skyscanner’s Everywhere Search can rank possible destinations from your departure point.
KAYAK Explore offers a map-based approach that lets you filter by budget and other criteria.
Google flights has excellent map coverage which updates in real-time based on your filters
Our verdict
Skyscanner is especially simple for the question:
“Where can I fly cheaply?”
KAYAK Explore may suit travellers who prefer a map and want to apply additional trip criteria.
Goolgle is best for applying filters across the map interface
Best for Price Alerts
There isn’t a dramatic winner here.
All four platforms now provide some form of fare tracking:
- Google Flights can track routes, dates and selected flights.
- KAYAK offers Price Alerts for chosen routes and dates.
- Skyscanner offers Price Alerts that notify users when fares change.
- Momondo also lets travellers create Price Alerts.
The best choice depends on which interface you prefer and where you carried out your initial search.
Best for Multi-City Flights
Again, there is no obvious universal winner.
Google Flights supports multi-city ticket searches.
KAYAK provides multi-city searching.
Skyscanner supports multi-city itineraries.
Momondo also provides a dedicated multi-city option.
For complicated itineraries, however, comparing more than one search engine can become even more important.
With more flight sectors, airlines, connection options, and booking combinations involved, search engines have more opportunities to return different results.
Which Has the Best Filters?
KAYAK and Google Flights are particularly good for travellers who know precisely what they want.
Typical filters across these services can include combinations of:
- number of stops;
- airlines;
- departure and arrival times;
- cabin;
- airports;
- journey duration;
- and other itinerary characteristics.
Google explicitly provides filters including Stops, Airlines and Times.
KAYAK also lets travellers refine searches extensively, along with flexible-date and nearby-airport functionality.
For most travellers, all four offer enough filtering to remove obviously unsuitable itineraries.
Which Site Finds the Cheapest Flights?
This is where the comparison becomes more complicated.
There is no permanent answer such as:
“Skyscanner is always cheapest.”
or:
“KAYAK always finds lower fares than Google Flights.”
Flight prices vary according to:
- route;
- travel dates;
- availability;
- airline;
- booking provider;
- itinerary;
- cabin;
- connection;
- and the moment the search is performed.
Different metasearch engines can also display different travel agencies and combinations.
We therefore tested this question separately rather than trying to answer it from a handful of anecdotal searches.
You can see the results in our:
That study is the better resource if price performance rather than features is your primary concern.
Do These Sites Sell the Flight?
This is an important distinction that travellers sometimes miss.
A flight comparison service generally helps you find a fare.
The eventual ticket may be sold by:
- the airline;
- an online travel agency;
- or another booking provider.
This means you need to evaluate the cheapest result in context.
Before paying, check:
- who is actually selling the ticket;
- the final checkout price;
- baggage allowance;
- seat-selection costs;
- cancellation terms;
- change conditions;
- whether separate tickets are involved;
- and the reputation of an unfamiliar booking provider.
The lowest headline number isn’t automatically the best overall booking.
Should You Use Google Flights, KAYAK, Skyscanner or Momondo?
Our answer is:
It depends what you’re trying to accomplish.
Use Google Flights when:
You want to understand how prices vary by date, quickly compare schedules or use a clean interface to explore different flight options.
Use Skyscanner when:
You are flexible about dates or destinations and want to discover where or when you might travel for less.
Use KAYAK when:
You want a feature-rich flight search with extensive filtering, flexible dates, nearby airports, alerts and destination exploration.
Use Momondo when:
You want another broad search of airlines and booking providers and want to compare what it finds against the other major metasearch engines.
But if your objective is specifically:
“I want to give myself the best chance of finding a competitive fare”
then relying exclusively on any one of them is difficult to justify.
Why Compare More Than One Flight Comparison Site?
This is the part of flight searching that is surprisingly easy to overlook.
Travellers already understand the benefit of comparison.
Instead of checking dozens of airline websites individually, they use a comparison engine to search many sources.
But if different comparison engines can produce different results, there is another logical layer of comparison:
compare the comparison sites themselves.
We sometimes describe this as meta-meta flight search.
A conventional metasearch journey looks like:
Traveller → flight comparison site → airlines and booking providers
FlightsFinder adds one more layer:
Traveller → FlightsFinder → compare multiple flight comparison resources → select from a broader range of prices and booking providers.
Instead of assuming one comparison engine has necessarily uncovered your best option, you can compare several leading search resources.
That does not mean we can guarantee the cheapest fare in existence.
No responsible flight search service can make that promise.
What it does mean is that you are less dependent on the results of one search engine.
Our Recommended Way to Search for Flights
For travellers who want to search thoroughly, we recommend combining several techniques.
1. Start with your preferred journey
Search the destination and dates you actually want.
There is no point finding a cheap fare that doesn’t fit your plans.
2. Check nearby dates
Move the departure or return by a day or two.
Google Flights, KAYAK and Skyscanner all provide tools designed to make date comparison easier.
3. Consider nearby airports
Travellers in multi-airport regions should investigate alternative departure and arrival airports.
For example, someone searching from London may have several realistic departure airports.
KAYAK allows up to 3 separate departure and arrival airports, while Google can highlight alternative airport possibilities.
4. Compare more than one search engine
This is where FlightsFinder can reduce repetitive searching.
Instead of treating KAYAK, Skyscanner, Google Flights or momondo as the final word, compare what multiple services uncover.
5. Compare the itinerary, not only the fare
A cheaper flight could involve:
- an additional stop;
- a much longer connection;
- an inconvenient airport;
- separate tickets;
- no checked baggage;
- or an unfamiliar booking agency.
A slightly more expensive itinerary may therefore represent better overall value.
6. Check the booking provider
If an online travel agency, rather than the airline, is selling the ticket, research the company before paying.
7. Verify the final price
Flight prices change.
Always check the final booking page before deciding to buy.
Frequently Asked Questions
Is KAYAK better than Skyscanner?
Neither is universally better.
KAYAK has an extensive collection of search, filtering, flexible-date and destination tools.
Skyscanner is particularly strong for flexible destination and month-level searches.
Which is more useful depends on the type of journey you’re planning.
Is Google Flights better than Skyscanner?
Google Flights is particularly good for visually comparing dates, schedules and fare patterns.
Skyscanner is especially useful when your destination or travel month is flexible.
Many travellers can benefit from using both.
Is Google Flights better than KAYAK?
Google Flights provides a cleaner experience for rapidly understanding fares and schedules.
KAYAK features a larger collection of dedicated travel-search tools and shows the final price with checked bags included. Google only shows cabin bags.
Again, they solve slightly different problems.
Is momondo better than KAYAK?
The two platforms have significant similarities, and both perform broad metasearch.
Rather than assuming one is universally better, the useful question is whether either one finds a fare or booking option the other does not.
Although both are run and owned by Booking Holdings, our tests show they can uncover different prices for the same route.
Is Skyscanner always the cheapest?
No flight comparison site is the cheapest for every route and date.
Is Google Flights a travel agency?
Google Flights is principally a flight-search tool rather than a conventional online travel agency. Travellers typically continue from Google to the relevant airline or booking provider to complete a purchase.
Does FlightsFinder sell airline tickets?
No.
FlightsFinder.com is not an online travel agency and does not issue airline tickets directly.
Our purpose is to help travellers search and compare flight options.
Which flight search engine should I check first?
There is no wrong starting point.
If dates are your main concern, Google Flights is particularly useful.
If you’re unsure where to travel, Skyscanner Everywhere or KAYAK Explore can be helpful.
If you’re performing a detailed fixed-route search, KAYAK, Skyscanner, Google Flights and momondo are all worth considering.
For a thorough fare search, however, we recommend comparing multiple sources rather than stopping after the first.
This is where FlightsFinder excels - allowing you to cross-check the final fares on each of these sites before going ahead and booking.
The Verdict: KAYAK vs Skyscanner vs Google Flights vs Momondo
All four platforms are excellent flight-search resources, but they have different strengths.
Google Flights stands out for visual fare exploration, date comparison and a fast, uncluttered search experience.
Skyscanner is particularly strong for travellers with flexible destinations or travel dates.
KAYAK is an excellent all-round search platform with flexible dates, alerts, destination exploration, nearby-airport options and extensive filtering.
Momondo provides another useful layer of airfare comparison and can be especially valuable as an additional search alongside the other major engines.
So we wouldn’t declare one of them the universal winner.
More importantly, we wouldn’t assume that choosing the best interface necessarily means finding the best fare.
That is why FlightsFinder takes a different approach.
Rather than asking travellers to choose between KAYAK, Skyscanner, Google Flights and momondo, FlightsFinder helps you compare leading flight search resources from one place.
Our philosophy is simple:
Don’t just compare flights. Compare the comparison sites.
