Qualiflyer

When Swissair began acquiring stakes in other European airlines in 1998, Qualiflyer was extended to become their frequent flyer programs as well.

[1] Originally, Swissair's partner airline Crossair and its high-end hotel chain Swissôtel also participated in the program.

Qualiflyer's affiliation to one of the world-class airlines caused membership to grow quickly to 2 million members in the first eight years.

Currently Swiss International Air Lines, the successor company of Swissair, is participating in the Miles & More frequent flyer program with Lufthansa.

Swissair and Sabena principally had several airplanes painted with a blue underbelly with "The Qualiflyer Group" titles applied near the nose.
