By Air:
Pattaya Airport, oh yes Pattaya has an airport also, kind of. Its actually called U- Tapao Airport, which is located about 1hr drive from the city. In previous years it has only had a rather unorganized skeleton service running between Bangkok and U-Tapao International airport, with only a few flights a week.
This has all since improved and changed with many international flights running a good schedule and even Air Asia have regular very reasonable flights to Pattaya now! If you arrive in BKK you can fly onward to U-Tapao and it takes you 45 min’s flight the remaining one hour, 40 km, journey to Pattaya. which already puts you in the same travel time frame as getting off the plane is BKK and jumping into a taxi directly. However if your travelling within Thailand or find this airport more convenient than BKK It could be for you!
