How to Find the Cheapest Flights to Bangkok from the U.S. and Europe

Last Updated on September 23, 2025 by admin

Finding cheap flights to Bangkok can save you hundreds or even thousands of dollars on your Thailand trip. With the right timing, apps, and booking strategies, you can score deals that make your adventure much more affordable. Flights can be significantly cheaper during low season and it may pay to experiment. But many travel during whichever month is most convenient.

1. Use the Best Flight Search App and Website

Skyscanner remains the most comprehensive flight search engine for Bangkok routes. Here’s why it outperforms competitors:

• Most airline partnerships: Searches 1,200+ airlines including budget carriers
• Flexible date search: Shows cheapest days within entire months
• Price alerts: Monitors specific routes and notifies you of drops

Pro tip: Use Skyscanner to find the best deals, then book directly with the airline to avoid third-party booking issues.

Google Flights comes in second, in part because it lacks many of the budget carriers Skyscanner has access to. Compare them both and you’ll see. This difference matters most when looking for cheap connecting flights on budget airlines that can get you to the big city airports you’ll fly overseas from.

2. Experiment With Different Departure Cities

In America, flights out of Los Angeles (LAX), San Francisco (SFO), and Seattle (SEA) can be $100 to $200 cheaper than flying out of New York City (JFK). Europeans can explore flying out of an alternative hub with the best deal. Common ones are London (LHR), Frankfurt (FRA), Amsterdam (AMS), and Paris (CDG). Especially if you don’t have a major airport near your home town, it can pay to be flexible geographically.

3. Be Flexible on Which Day of the Week You Depart

It can be cheaper to fly midweek on some routes versus other days. And the airlines with the best fares may only fly on particular days of the week. So be flexible and see if you can fly either before or after your preferred date. Tuesday and Thursday departures are often said to be cheaper than weekend departures, for example.

4. Don’t Insist on Nonstop Flights

While any route could ultimately be the cheapest for your dates, flights with layovers are typically cheaper than nonstop flights. Some airlines may allow to you structure your flights such that you can spend a night or two in a city along the way, giving you two trips in one if you’re adventurous. Americans can’t presently fly nonstop from the U.S. to Bangkok, but Europeans have that flexibility.

5. Pay Attention to Baggage Charges and Other Fees

Be mindful of baggage charges when selecting airfare. Options that initially seem the cheapest may turn out not to be if you need to check baggage or want to select your seat in advance. Some airlines try to game the system by offering low base fares. Focus on the final price with baggage and seat selection included.

6. Fly Free using Frequent Flyer Miles

The cheapest option of all is to fly for free using frequent flyer miles from generous credit card signup bonuses. Americans have the advantage over Europeans here.
