Chiang Mai International Airport Departures
Note that you and your bags must pass through a security screening in order to get into the passenger terminal.
If traveling on an international flight, you check-in at the international terminal. Otherwise, use the domestic terminal. In both cases check-in is on the ground floor of the terminal. After check-in, passengers can proceed upstairs to the second level where the departure lounges are located. International passengers will need to go through passport control before gaining access to the lounge.
