Passenger services grew after the Second World War. Calcutta became a destination for the world's first jet-powered passenger aircraft, the de Havilland Comet, on a British Overseas Airways Corporation (BOAC) route to London. Furthermore, in 1964 Indian Airlines introduced the first Indian domestic jet service, using Caravelle jets on the Calcutta–Delhi route. Between the 1940s and 1960s, the airport was served by several major airlines including Aeroflot, Air France, Alitalia, Cathay Pacific, Japan Airlines, Philippine Airlines, KLM, Lufthansa, Pan Am, Qantas, Swissair and SAS.
