Question

How long is a flight to Thailand from St. Louis?

Answer 1

roughly 23 hours

Answer 2

If you were to get a direct flight from Bangkok to St. Louis the flight would be approx. 16 Hrs 34 Min. You can get flight times for airports all over the world at https://www.jets.com/

Answer 3

While the previous answer is correct...no airlines actually have non-stop flights between Thailand and St. Louis.  So unfortunately the best answer I can give you is, it depends on where you change planes, and how long your layover is.

It also depends on if we're talking Bangkok (so probably 1 plane change) or a smaller city in Thailand (thus probably 2 plane changes).
