Bangkok Airports
Thailand is now operating two airports in and just outside Bangkok. Suvarnabhumi is the newly opened airport, located in Samut Prakan Province. Airport codes for Suvarnabhumi and Don Muang are BKK and DMK, respectively.
Passengers who have to connect their flights between Suvarnabhumi and Don Muang Airports, should allow at least 50 minutes to travel (it can be 1-2 hours depending on traffic). The distance between the two airports is about 40 km by using the expressway. The metered taxi will cost around 400-500 baht (depending on traffic), including expressway tolls and 50 baht surcharge on the meter.
