Frequently asked questions

Is it cheaper to buy a plane ticket from IAD to THL last minute?
When it's time to book your flights, it's better to be prepared. While you could pick up a last-minute deal on a Washington Dulles Intl. Airport (IAD) to Tachilek Airport flight, tickets usually don't get cheaper as the date of departure nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to lock in a domestic flight is between 28 – 35 days ahead. For international trips it's between three and four months.

Washington to Tachilek flights touch down at Tachilek Airport (THL). This terminal is around 3 kilometers east of central Tachilek. Snag an impressive deal with Expedia and then ready yourself for an adventure.

Make changes quickly to your Washington Dulles Intl. Airport (IAD) to THL journey via the Expedia Trips portal. Before making any amendments, read the rules and conditions in your itinerary to learn what the carrier will allow you to do and whether fees apply.
