This used to be Bangkok’s only airport before the new shiny one was built. This one is closer to city centre, but there is no good public transit to it. I used a taxi which was quick when it took the motorway and I paid a 60 baht toll on top of the fare.
This airport is now almost exclusively used by Air Asia, but a few small low cost airlines use it to. It also seems popular for private jets as it is closer to the city.
Air Asia likes it because it is less congested by other flights, so it saves them money on fuel costs since they can usually land right away and they don’t need to wait too long on the runway to take off.
Inside it seems like a rather large terminal with not a lot of people in it! It seems to have all the services you would need though, and immigration and security were quick and easy.
Next stop Myanmar…..
