Hounslow Heath Aerodrome was a grass airfield, operational 1914–1920. It was in the London borough of Hounslow, and hosted the British Empire's first scheduled daily international commercial flights, in 1919. The site today includes the main remaining part of Hounslow Heath. The last commercial flights took place in 1920, after which services moved to Croydon Airport. Hounslow Heath Aerodrome is not to be confused with Great West Aerodrome, which opened nearby in 1929, and which is now Heathrow Airport.
