Polonia International Airport (Indonesian: Bandar Udara Internasional Polonia) (IATA: MES, ICAO: WIMK) is an airport located in Medan, North Sumatra, Indonesia, about 2 km from the downtown. It served flights to several Indonesian and Malaysian cities, along with a flight to Singapore and Thailand.
Previous international flights had been opened to Hong Kong, Taipei, Amsterdam, Phuket, Chennai, Johor Bahru, Malacca and Ipoh. In terms of passenger numbers, Polonia was the fourth largest airport in Indonesia after Soekarno-Hatta, Juanda, and Ngurah Rai. Passenger service charges for each departed through domestic terminal was IDR 35,000 ($4.1) and IDR 75,000 ($8.8) for international terminal.
All flights and services from this airport shifted to Kuala Namu International Airport on 25 July 2013. After the Kuala Namu International Airport operates, Polonia's ICAO code is changed to WIMK, while WIMM is assigned for Kuala Namu. Polonia International Airport now belongs to the Indonesian Air Force and will be transformed into a military base. It will be designated as Soewondo Air Force Base and will host the Western Surveillance Wing including eight CN-235 tactical surveillance airplanes.
The airport located on 144 hectares land area. There is a single asphalt runway (05/23) which is 3000 m long and 45 m wide, but has only 2,900 m of usable length. There is no run-off space beyond the runway thresholds, and the airfield is surrounded by residential areas. It is often said that its location in a residential district, the wealthy Polonia area, is due to a superstition that the loud noises from aircraft drive away malevolent spirits.
Until recently, the airport consisted of an international and domestic terminal. A fire in the international arrivals area in 2006 caused damage to the airport, reducing the baggage reclaim area to a small section inside the terminal. On 2 December 2007, the domestic terminal was damaged by another fire. There were no injuries, and the separate international terminal was not affected.
