In 1948, the airport in Dübendorf, which served as the base of Swissair, was relocated to Zurich-Kloten. Military aviation continued in Dübendorf. The next year Swissair plunged into a financial crisis due to a sudden devaluation of the British pound because fares, except traffic to the United States, were calculated in British currency. At that time, the traffic to England made up 40 percent of Swissair's revenue.
