Getting to and from the airport
Vibhavadi Rangsit Road is the main route linking BIA with downtown Bangkok. Other transport webs bringing us to downtown are toll-way and expressways which facilitate passengers' trip with more convenience and fastness.

There are several kinds of transportation services provided for passengers such as limousine of Airport Associate Co., Ltd. and of Thai Airways International Public Co., Ltd. car rental service, taximeter and airport bus. Their counters are in the arrival hall of international passenger terminal. Both limousine and taxi are on service at Domestic terminal as well.

Information Counter Airport Information Counters are in the passenger hall and passenger lounge of international passenger terminal and domestic passenger terminal. Airport information officers are willing to give necessary information to passengers with Thai courtesy.

Terminals

The Airport has two terminals: International and Domestic. You arrive at Bangkok Int. Airport. on the first floor (ground). Departure (international) is on the third flour. The second floor is for car parking and a "secret" 500m footway linking international and domestic terminals.

Be careful for booking unknown hotels at Bangkok Airport and also be careful of any offers (taxi, hotels, resorts) you receive after leaving the aircraft (you will get a lot of them).

You may go to the domestic airport for a domestic flight with Bangkok Airways or Thai Airways, or you can go to Bangkok city for a hotel, railway station etc...

Whatever you do: Do not forget your baggage! This is very important if you want to go to the domestic airport. Your baggage will not be redirected automatically at Bangkok Airport, so you have to pick it up, move to domestic airport and check-in your baggage again. You would not be the first traveler who arrived at Koh Samui, while their baggage rests in Bangkok.

To go to the domestic terminal, you must leave the entrance hall, keep right and look for a sign: Shuttle-bus to domestic. Here stops a small vehicle for carrying travelers to the domestic airport and back - for free.

Alternatively you can walk on the passenger gateway at the second floor (about 15 min). The domestic airport is quite small, so you will have no problem to find your check-in counter.
