Doha International Airport (IATA: DIA, ICAO: OTBD) (Arabic: مطار الدوحة الدولي) is an airport in Doha, Qatar. It was Qatar's commercial international airport until Hamad International Airport opened on 27 May 2014. While all scheduled commercial traffic ceased, the airport site and existing runway are still used by Qatar Emiri Air Force, Qatar Amiri Flight, Rizon Jet, Gulf Helicopters and Qatar Aeronautical College. It also acts as a state/diplomatic airport catering to both Qatar Amiri Flight (which is based at the airport) and state-visit flights. The airport welcomed commercial flights again on 15 September 2022 for selected airlines to handle increased traffic for the 2022 FIFA World Cup that Qatar hosted in November.
