In 1947 the rise of shareholder capital to 20 million Swiss francs enabled long haul flights to New York, South Africa, and South America with Douglas DC-4s. The modern Convair 240, the first Swissair plane with a pressurized cabin, was used for short- and medium-range flights from late 1948. The first Swissair DC-4 flight to New York was routed via Shannon, Ireland, and Stephenville, Newfoundland, on May 2, 1947, although it actually ended in Washington, D.C., due to fog at New York's LaGuardia Airport. The total elapsed time was 20 hours and 55 minutes.
