How Can You Find Cheap Flights to Asia?

2 Foolproof Ways of Discovering the Cheapest Flights to Asia

1.) Use FlightsFinder's 'Flex Month' search:

Go to the FlightsFinder.com homepage enter a departure airport and an arrival destination - e.g Bangkok. Then instead of entering a date select the tab which says 'Flex Month'. This will show you the cheapest flights in every month of the upcoming year.

Once you select a flight you will then be taken to flight grid which will then allow you to choose your exact dates of travel with price estimates shown.

2.) Use Google flights search engine:

Google flights is one of the best search engines for flight discovery. Follow these exact three steps to discover amazing flight deals.

1. On the homepage you can enter up to 7 destination cities. This will force the engine to scan all of those routes simultaneously.

2.) Once entered you can filter the flights shown - so if you prefer direct or one-stop flights you can specify it in the filters section. You can also specify airlines, stopover lengths and many other options.

3.) Next is where the magic happens on Google flights. Now when you click the calendar it will be populated with prices with your exact parameters preserved. So if, for example, you selected direct flights only you will see prices for direct flights only in the calendar. This is the only calendar in the world which allows you see calendar prices with filters preselected.

Finally: After you have found a good price we always recommend plugging those exact dates into FlightsFinder and comparing multiple aggregators to see if you can make even more of a saving.

OUR FOUNDER SAYS

“When searching for flights to Asia, compare the same dates across several engines and weigh the fare against the journey time, baggage and connection arrangements. A cheaper ticket is only good value if the whole trip works for you.”

 

Why Compare Multiple Sites When Finding Flights to Asia?

Why comparing multiple sites matters

One thing that made a big difference for me over time is realising that no single flight search engine shows every deal.

I used to check just one site and assume that was the best price. It rarely is.

Different platforms have access to different airlines, deals and pricing structures. A flight that looks expensive on one site can be noticeably cheaper on another.

That is why I now always compare across a few options like Skyscanner, KAYAK and Google Flights.

I’ve personally seen:

👉 This is exactly why I always compare multiple sources.

It takes a couple of extra minutes, but it is one of the simplest ways to avoid overpaying. Luckily, FlightsFinder makes the task so much more simpler.

(FlightsFinder lets you compare the most effective flight comparison sites from one dashboard.)

The Best Routes for Cheap Flights to Asia

1. One-stop flights (best overall value)

This is where I find the majority of cheap deals.

Typical stopover hubs:

Airlines that consistently offer strong value:

Why this works:

This is the sweet spot between price and comfort.

2. Direct flights (good — but only during sales)

Direct flights are convenient, but usually more expensive.

Occasionally, budget long-haul airlines offer deals:

Only worth it if:

3. Two-stop routes (cheapest — but risky)

Yes, they can be cheaper.

But:

I rarely recommend this unless the saving is significant.

Real example of a deal I found

Here is a recent example of the kind of deal you can find with the right approach.

(This was a return flight to South Asia I found using FlightsFinder, showing how prices can vary depending on how you search.)

This is why I always compare a few options rather than relying on a single site.

I regularly post the best deals I come across on the FlightsFinder social channels - so if you have a moment I recommend you check them out :)
