Bucharest Henri Coandă International Airport (Romanian: Aeroportul Internațional Henri Coandă București) (IATA: OTP, ICAO: LROP) is Romania's busiest international airport, located in Otopeni, 16.5 km (10.3 mi) north of Bucharest's city centre. It is currently one of two airports serving the capital of Romania. The other is Aurel Vlaicu Airport, which no longer serves scheduled passenger traffic. During World War II, the airport in Otopeni was used as an airbase by the German Air Force. Until 1965, it was a major airfield for the Romanian Air Force, with Băneasa Airport serving as Bucharest's commercial airport. In 1965, with the growth of air traffic, the Otopeni airbase was converted to a commercial airport. The runway was modernized and extended to 3,500 metres (11,500 ft) from the previous 1,200 metres (3,900 ft), making it one of the longest in Europe at that time .
The airport is named after Romanian flight pioneer Henri Coandă, builder of Coandă-1910 aircraft and discoverer of the Coandă effect of fluidics. Prior to May 2004, the official name was Bucharest Otopeni International Airport (Romanian: Aeroportul Internațional București Otopeni). Henri Coandă International Airport serves as headquarters for TAROM, the country's national airline. It also serves as a base of operations for low-cost airlines Blue Air, Ryanair and Wizz Air. It is managed by The National Company Bucharest Airports S.A. (Compania Națională Aeroporturi București S.A.). The military section of the airport is used by the 90th Airlift Flotilla of the Romanian Air Force.
