Bangkok is served by two airports: Suvarnabhumi Airport also known as the New Bangkok International Airport and Don Mueang International Airport also known as Old Bangkok International airport.

Most of the buses operate from the bus terminal which is at some distance from the terminal and is reached by a free shuttle. Various modes of transportation such as taxis, limos and buses ply from the airport to help passengers to get into the city center.
