Société Belge des Transports par Air SA, known by its short form Sobelair, was a Belgian charter airline that operated from 1946 to 2004.

[4] Sobelair was founded as a charter airline on 30 July 1946, originally (only during the initial months) known as Société d'Etude et de Transports Aériens, abbreviated SETA.

In 1997, Sobelair operated chartered passenger flights from Zürich to San Francisco and Las Vegas on behalf of Swissair.

[6] In October 2001, Swissair went bankrupt, which was followed by the demise of partner Sabena in November of the same year, which led to the future of Sobelair becoming uncertain, too.

TUI Travel placed an offer for taking over Sobelair's aircraft in order to create a Belgian airline subsidiary, provided that creditor protection would be granted.
