According to Marcel Biedermann, the managing director of intercontinental markets for Swiss, there were three possibilities: stay independent as a niche carrier, shrink to an unrecognisable level, or attach onto another airline group. The last choice was taken. Swiss talked to Air France–KLM, British Airways, and Lufthansa. However, Swiss was tied up with debt and an uncertain future and seemed to be an unattractive investment. After merging with KLM, Air France said they were too busy to deal with Swiss joining them. British Airways was open, and Oneworld partners thought Zurich Airport would be a viable alternative hub for London Heathrow.
