Seaboard & Western - When the company started its operations on 10 May 1947 it was the first all-cargo airline to fly over the Atlantic on a regular basis. The main type of aircraft was the Douglas DC-4. Seaboard & Western was the first and the only airline to order the commercial freighter version of the 1049D, on 12 December 1952. The four Super Constellations were delivered between August and September 1954 and deployed on routes like New York - Shannon - London - Frankfurt. Followed by services between Baltimore, Philadelphia, New York and London, Amsterdam, Paris, and Zurich.
