The airport has two terminals: Terminal 1 is used for international flights, and Terminal 2 for domestic flights. Terminal X for charter flights opened in February 2014.
Due to record-setting passenger numbers, the airport has undergone a 5.14 billion baht expansion and renovation which will be completed in March 2016. A test flight will use the new terminal on 14 February. Testing will be conducted through May, and the terminal will be officially opened on 1 June. The capacity of the new international terminal is five million passengers per year. The expansion increases airport capacity to 12.5 million passengers a year from its previous capacity of 6.5 million. A new car park as well as air cargo office are also planned. Terminal construction is expected to start in July 2012. A rail link from an alternate airport, Krabi, was suggested in 2012, as Phuket is congested and has little room to expand beyond 2015.
Phuket is a favorite tourist destinations in the region. International passengers mainly come from Asia Pacific and Europe. In 2012 it ranked second busiest in total passenger traffic, after Suvarnabhumi Airport in the Bangkok metropolitan area. In mid-2015 the airport, designed to handle 20 flights per hour, was servicing 23 per hour.

Aircraft movements grew 11.6 percent to 84,758, with 43,996 international (up 7.63 percent) and 40,762 domestic (up 16.1 percent).
