There remains intense speculation about the future of Baby and maybe (baby!!!) only the full and final press release on sale will answer all the questions.
But in terms of speculation there could be considerable overlapping at EMA with both Baby and Jet2 currently operate from.
However what could be interesting is Jet2 taking over Baby's presence at BHX, currently an airport it does not serve but which still does have an impressive Baby facility (check-in etc) in Terminal 1.
