“If you need to travel between Bangkok's two airports, you can grab a seat on the free shuttle.”
Dealing with anything aviation-related can be a stressful experience, especially if it means traveling to a foreign city where you don't speak the language, are unfamiliar with the local customs, and don't know your way around. Flying to and from Bangkok, Thailand, can be such an experience. Airports are confusing places, and Bangkok's two airports, Suvarnabhumi and Don Mueang, are no exception. Hundreds of airlines operate out of these hubs each day. You have to check in, deal with security and immigration, board, and then fight for overhead space in the cabin.
