BY AIR

Domestic flights should be booked as far in advance as possible, though tickets can be bought at the airport if available; the domestic departure tax is included in the price of the ticket. Thai Airways is the main domestic carrier and flies to over twenty major towns and cities; Bangkok Airways currently covers just a few routes from the capital, including Ko Samui, Ranong and Hua Hin. All domestic flights leave form Don Muang airport.
The fastest, most expensive way of getting to the airport is by metered taxi, which can cost anything depending on where you are and how bad the traffic is. If you leave the downtown areas before 7am you can get to the airport in half and hour, but at other times you should set off at least an hour before you have to check in.
Every guesthouse and travel agent in Banglamphu, and many hotels elsewhere in the city, can book you on to one of the private minibuses to the airport. Those running form Banglamphu depart approximately every hour, day and night, though you’ll get picked up from your accommodation, you should book yourself on to a minibus that leaves at least an hour and a half before check-in commences as it can take up to 45 minutes to pick up all passengers, after which there’s the traffic to contend with.
