Well, in my book it says that credit suisse and UBS bought the CROSSAIR stake out of the bankrupt SairGroup. They did not buy out the Swissair part, which can thus be considered as bankrupt.
By the way who came up with this foolish idea to expand Crossair with 26/26 aircraft (actually 27/27) and crew ex swissair? As you can read above this will never mix. If we would have continued like DAT in Belgium (fly a few profitable longhaul flights via codeshare and some a330s flown bij ex sabena crew) all swissair flightcrew would be on the street but the cantons (read: the people living in Switserland) would have saved a LOT OF MONEY.
This is a waste of time and an even bigger waste of money.
Good luck with your civilised airline.
(do not forget to take your nightstopkit when you go out flying as they might try to confiscate your aircraft)
