MAN,
For somone such as AF to leave Servisair after so many years is a pretty big blow for them I imagine...
Depends on the reasons for the move, but I know Servisair aren't in the greatest of shapes at the moment, so maybe they decided it was time for a fresh start (in which case why Aviance???).
Depending on the how the acquisition of G* by a much larger world player is progressing, there may well be other contracts on the move...
Watch this space...
