Yangon International Airport ( ) is the primary and busiest international airport of Myanmar. The airport is located in Mingaladon, north of central Yangon. All ten Myanmar carriers and about 30 international airlines operate at Yangon International Airport. The airport is also colloquially known as Mingaladon Airport due to its location. History During World War II, the airfield was called RAF Mingaladon and served as an operating base for fighter aircraft such as: No. 60 Squadron RAF from February 1941 to February 1942 flying Bristol Blenheim I No. 67 Squadron RAF from October 1941 to March 1942 flying Brewster F2A Buffalo and Hawker Hurricane IIs No. 135 Squadron RAF from January–February 1942 flying Hawker Hurricane IIs No. 681 Squadron RAF from June to September 1945 flying Supermarine Spitfire 3rd Squadron of 1st American Volunteer Group (Flying Tigers) of the Chinese Air Force flying Curtiss P-40s There was also a Communication Flight of the Burma Volunteer Air Force equipped with Tiger Moths and Westland Lysanders and anti-aircraft support for the airfield was provided by members of the 12th Burma Rifles. Mingaladon was then used by the Japanese, and Japanese bombers based in Bangkok were moved forward to Mingaladon when there was a full moon. The British at the Wireless Experimental Centre in Delhi were breaking BULBUL the IJA air-to-ground code, and could predict Japanese air raids. On one occasion Allied nightfighters "got the lot and all night we could hear Mingaladon air base calling for its lost children".

Once regarded as the best in Southeast Asia and the primary airport serving that region, the airport fell into disrepair and remained that way for decades, as new superhubs like Singapore Changi Airport, Kuala Lumpur Sepang, Bangkok Suvarnabhumi and Jakarta Soekarno-Hatta were built and superseded Yangon's facilities. Airport capacity was boosted to 6 million passengers per year in early 2016. Currently, there are plans to build a completely new and larger airport, Hanthawaddy International Airport, on a much larger site and somewhat away from Yangon.
