There are reports of this airport being disorganised, leading to long queue times.
National or regional holidays can also swell passenger traffic and add to the waiting times. Come armed with reading/viewing material and things for the kids to do.
The airport is 24km from downtown Bangkok.
Taxi - metered taxis are available outside the Arrivals halls. There's an airport surcharge and travelers also pay any toll fees. It is recommended that travelers have the address of their intended destination written in Thai.
Bus - a dozen or so bus routes connect the airport with points around Greater Bangkok. If you're transferring to Suvarnabhumi, Bangkok's other international airport, you can take a free shuttle bus, which runs from 05.00 to 23.00. Though the transfer should only take 1 hour, leave yourself plenty of time as traffic can sometimes double or triple the normal journey duration.
Train - a bridge connects the 2nd Floor of Terminal 1 with Don Muang train station about 500 meters away. From there, trains run every 30 minutes to the central railway station, Hua Lumphong in downtown Bangkok.
Car rental - car rental firms operate from the Arrivals hall in Terminal 1.
The 2 terminals are connected by a shuttle bus which runs every 15 minutes. Alternatively, there's a passenger walkway which will get you from one terminal to the other in roughly 5-10 minutes.
The Sleep Box on the 4th Floor of Terminal 2 has small rooms available for day or night use. Just outside the airport, but connected to it by climate-controlled walkway, is the Amari Don Muang Airport Hotel, where you can relax by the outdoor swimming pool.
Regardless of the airline you fly or ticket you hold, membership means a warm welcome awaits.
