Then the question comes , what about all the other airlines which SR has invested in? What do you think they want to be? part of Qualiflyer without Swissair? The biggest question is the the Qualiflyer Frequent Flyer Programme. If Swissair goes to OneWorld, then the OneWorld co-branding will apply to Qualiflyer members. The problem lies here - Qualiflyer only has 2 levels. Regular and Elite. (There is a level higher than elite but it's invitation only, so that rules out it being emerald). All the other Qualiflyer airlines like SN, OS,NG, TK, IM etc have branded together to market Qualiflyer as THEIR one and only frequent flyer programme. So if Sr joins OneWorld, wouldn't the 1w branding apply to them too?
