Although Flyglobespan is the most likely to pick up the high volume routes (I would include Paris CDG in your list) they would most likely use the same 738 that they intend to use on the Tenerife route, and if bmibaby's reason for leaving MME is even slightly true, which I don't believe it is, how are GSM going to fill a 738???
It would be handy if they could acquire a couple of extra 736's from SAS.
