I would go as far as to say 70% of the users on the qantas forum are looking for a solid reason to leave QF if only another global airline would step up to the plate. Another 10% are locked into contracts (although not enforcable by law in AU) , and the other 20% think they have built up too much rapport with Qantas (status credits etc) or are too comfortable with how QF operates to change.
I could go on for hours about this topic but it wouldn't achieve anything beyond cutting some deep wounds.
