Belair, legally Belair Airlines AG, was a Swiss charter airline headquartered in Glattbrugg operating out of Zürich Airport and EuroAirport Basel Mulhouse Freiburg. It was a subsidiary of Air Berlin and operated under the Air Berlin brand name until the 31 March 2017. During the 2017 summer season, it flew on behalf of its sister company Niki and was shuttered by then-bankrupt Air Berlin on 28 October 2017. History The first Balair (1925-1931) Basler Aviation AG - Balair was founded by Balz Zimmermann in 1925 in Basel. The name Balair is a reference to the French name of the Basel: Bâle. The first route was from Basel to Freiburg and Mannheim. Balair grew rapidly. In 1929 Basel Airport was the largest airport in Switzerland, with direct flights to Zurich, Geneva, Lyon, Karlsruhe and Frankfurt. In response to the Great Depression, Balair (based in Basel) and Ad Astra Aero (based in Zurich) merged on 1 January 1931 to form Swissair, headquartered in Zurich. Up to that point, Balair had carried over 18,000 passengers, 320 tons of cargo and 143 tons of mail. The company only flew in the summer and was mainly financed by federal subsidies and transportation of mail for the Swiss post office. The second Balair (1953-1993) On 5 October 1952, the Basel electorate voted for the creation of a limited company. Soon then, the second Balair was founded in January 1953, with Hans Peter Tschudin elected as the first president. In its early years, Balair was active in flight training, aircraft maintenance and handling Swissair aircraft at Basel-Mulhouse Airport. Balair entered the charter business with the acquisition of two Vickers Vikings in June 1957. In 1959, Swissair acquired a 40% stake in Balair. Two Swissair DC-4s were added to the fleet and later the DC-6 came into service in 1961. During the Biafran airlift (1967–71), chartered aircraft, including C-97 Stratocruisers, delivered humanitarian aid to a remote Biafran airstrip in eastern Nigeria. The airline's first jet aircraft was the Convair 990 Coronado and then the McDonnell Douglas DC-9-32 entered service followed by a Douglas DC-8-63CF which it flew on routes to Colombo, Bangkok and Rio de Janeiro. In 1979, Balair added a McDonnell Douglas DC-10-30 to its fleet. By 1982, Balair became an all jet airline and by 1986, the Airbus A310-300 and MD-82 were the mainstay of the fleet. Later, Swissair operated charter flights using the Balair name.
