Atlantis was a German charter airline based at Frankfurt Airport.

[1] The airline was established in 1966 as Nordseeflug Sylter Lufttransport and started seasonal scheduled services the same year with a Douglas DC-3 from Hamburg to Westerland.

In 1968 it was renamed to Atlantis and received a permit from the Civil Aeronautics Board to operate transatlantic inclusive-tour flights to the United States with Douglas DC-8.

Atlantis also operated affinity group charter flights and charter flights to destinations in the Mediterranean with McDonnell Douglas DC-9.

Despite the airline's cooperation with several tour operators it ceased operations on 19 October 1972 due to an uncertain financial perspective.
