Fleet News not sure where you get your info from but you are a little behind the times.
AC have now decided not to go with Aviance after all.
How are Menzies expanding??? They got FI last October but not aware of anyone else.
UA - Your info about contracts is correct. They now only handle NZ.
BA - Handle more airlines? If anything I would have thought they were looking at subcontracting their own handling!
Still this is a rumour mill after all!
