Cheap flights are low-cost tickets typically offered by both budget and full-service airlines at significantly lower rates than other available fares. Airlines regularly use dynamic pricing to set their total flight costs. Generally speaking, the lower the demand, the lower the price; the higher the demand, the higher the price. This rule applies to both no-frills carriers and traditional airlines. The secret to saving money is knowing exactly where, when, and how to book the most economical option.
The most efficient way to start your hunt for low fares is by using a flight comparison website. These platforms scour hundreds of airlines and online travel agents to find the best deals for your route.
Many also offer powerful tools like flexible date calendars, price predictors, and alerts that let you track airfares and book at the optimal moment.
The most famous of these websites include:
The problem with these sites, however, is that they each employ different partnerships, search features, data sources, and pricing algorithms, which means the lowest price might appear on one website one day and on another the next.
The ultimate solution is to compare results from several flight comparison sites to ensure you find the cheapest ticket.
Flights Finder is a meta-meta search® engine that aggregates the results from the top airfare comparison sites into a single, easy-to-use dashboard. Our platform lets you quickly compare prices head-to-head across Skyscanner, Kayak, Google Flights, Cheapflights, Momondo, Kiwi, Jetradar, and more.
It is the fastest way to ensure you never miss the cheapest available fares, combining multiple powerful search networks into a single, comprehensive platform. In fact, in our experience, it is not uncommon to save £50–£100 per passenger simply by cross-checking the best comparison sites.
In a recent test by Flights Finder, a week-long return Flight to Phoenix, Arizona from London in December showed significant price variation. Skyscanner listed the cheapest non-stop option at £1,959, while Kayak showed the exact same itinerary for £1,856. That is a saving of £103 per person, or £412 for a family of four.
See the screenshot evidence below:

Comparison sites are great at ‘finding’ the cheapest airfare, but they don't actually ‘sell’ you the ticket. They act as large digital directories which show you which airline or travel agent has the best price. Once they have found you the cheapest flight, they will redirect you to an airline or online travel agent to complete your booking and purchase your flight.
Yes, it is safe to book through a comparison engine, as they work only with reputable airlines and well-established online travel agents. However, agents come in all shapes and sizes, so it is worth checking third-party reviews of the merchant you wish to book with before parting with your hard-earned cash.
Some comparison sites, such as Google Flights. Kayak and Skyscanner, give you the option of booking directly with the airline on most routes, which many people prefer if they don't feel at ease booking through a third-party agent.
Flights Finder makes it easy to identify the cheapest available flight and presents multiple booking options, allowing you to choose to book where you feel most comfortable.

A hidden-city ticket is when it is cheaper to buy a flight with a layover and get off at the connection point rather than booking a direct flight. For example, if you want to fly to Rome, you might find it cheaper to book a flight to Türkiye that includes a stopover in Rome. The strategy involves disembarking at Rome and simply discarding the final leg of the journey.
While this travel hack can save you money, it comes with important caveats. First, you cannot travel with checked luggage, as those bags will automatically continue on to the ticketed final destination. Second, this practice violates the airline's contract of carriage, which could result in the airline invalidating your frequent flyer miles or banning you in a worst-case scenario.
Flights Finder displays available hidden-city ticket options via Skiplagged, which you can easily search directly through our all-in-one dashboard.
An error fare occurs when an airline accidentally makes a pricing mistake and publishes a ticket price well below the actual average rate. While these mistake fares are rare, they do happen from time to time.
Flights Finder's broad "Everywhere, Anytime" search functionalities enable you to spot these pricing anomalies quickly. You can read our detailed guide on how to find error fares to learn more. Alternatively, you can sign up for free specialist platforms like Secret Flying, which actively track down these specific mistake fares on your behalf.
We also manually track and post the best error fares and jaw-dropping flight discounts directly to our community channels. Be sure to follow us on TikTok, Instagram, and YouTube so you never miss a flash deal.
There is a common perception that the more you search for a particular route, the higher the price will rise as airlines track your intent. In our experience, this is a persistent myth rather than an industry reality. However, if you want to be completely certain, you can easily switch your browser to incognito or private browsing mode to ensure your search history is not being tracked.
Yes, it can sometimes be cheaper to book your ticket in a foreign currency due to shifting exchange rates. An effective strategy involves changing the regional point-of-sale market within your chosen search platform to compare localised prices side-by-side.
Flights Finder makes this process effortless. By selecting a different territory from our dropdown country selector, our dashboard instantly surfaces all available aggregator fares published specifically for that geographical market.
Please note that you should always review the provider's terms and conditions before purchasing a ticket through an alternate regional market, and check if your credit card charges international transaction fees.
Our research shows that for short-haul flights, the optimal booking window is 1 to 3 months before departure. For long-haul itineraries, it is generally best to secure your tickets 4 to 8 months in advance.
Because airline ticket pricing is not an exact science, we highly recommend monitoring fares using a flexible date calendar or setting up automated price alerts for your specific route. These tracking features can be configured quickly and easily on most major comparison platforms.
Historical industry data demonstrates that it is generally cheaper to fly on a Tuesday or a Wednesday. However, because airline pricing fluctuates constantly, these savings are never completely guaranteed.
The most efficient way to verify current rates is to utilise a flexible date calendar. Flights Finder offers an interactive grid calendar that makes it effortless to spot the lowest-priced travel days. We recommend using our grid alongside other comparison tool matrices to ensure you capture the absolute best deals available.
In most cases, utilizing a VPN does not affect airfares, as tickets are primarily priced based on the specific route and origin you are searching.
However, a VPN can be helpful when booking domestic flights within a foreign country. In these specific circumstances, airlines occasionally offer lower "resident-only" rates meant exclusively for the local population. You should always thoroughly read the terms and conditions of these tickets before booking to ensure you meet their eligibility criteria.
The standout features of Google Flights include its interactive "Explore" map and the ability to input multiple departure and arrival airports simultaneously. Another powerful capability is its historical price grid, which allows you to track airfares over time and filter your results with precision.
However, it is important to note that Google Flights does not always display the absolute lowest rate on the market. In many instances, Skyscanner and KAYAK can beat their pricing. Because of this variation, you should always cross-reference rates across multiple aggregators before making your final purchase.
The world's most prominent low-cost carriers include AirAsia, easyJet, Eurowings, Jetstar Airways, Ryanair, Scoot, Southwest Airlines, TUI, Vueling Airlines, and Wizz Air.
Flights Finder searches the vast majority of these budget operators via our integrated comparison engines. However, please note that select carriers, such as Southwest Airlines, do not share their pricing data with some third-party comparison sites, but they do show up on Google Flights.
A phantom fare occurs when you spot an exceptionally low price on a flight comparison site, but the moment you click through to book, the fare suddenly vanishes or increases substantially.
While this is highly frustrating, it typically happens because data aggregators pull ticket pricing from multiple external sources, causing a slight cache lag before surfacing the most up-to-date rates. Alternatively, that specific low-cost seat tier may have simply sold out during your search session, as live airfares are constantly traded in real time.
The best workaround is to utilise Flights Finder. Because our dashboard lets you view multiple alternative booking options from various search engines simultaneously, a sold-out fare on one site can be quickly cross-referenced to see if it remains available to book on another platform.
"Our flight data shows that you should cross-check at least four separate leading price aggregators to be sure you've caught the best deal. If you book through an online travel agent, make sure you check third-party reviews before parting with your money."
