Budaörs airfield now serves general aviation but it was once Hungary's only international airport. Planning for the airport started in 1935 and it was completed in the summer of 1937 becoming the home base of Malert (the forerunner airline of Maszovlet that later became Malév). Almost as soon as it opened, Budaörs was too small and lacked room for expansion. Ferihegy was ready in 1943 but severely damaged in WWII and did not open until May 1950 taking all airline traffic with it. At Budaörs the original 1936 terminal building still survives as a cafe and admin building.
