The Jet2 operation at EMA is little more than a quasi ITX operation, in fact apart for a few routes from LBA and MAN the entire operation is essentially a bucket and spade one.
If Jet2 were to try and muscle in, the you'd be kissing goodbye to the business schedules connecting EMA to Glasgow, Edinburgh, Paris etc - services that to be a "real airport" EMA needs.
To be honest I can't see EZY coming back with a full blown base, I could instead see FR, at least in the short term stiffling competiton by taking over many of the more profitable routes - and EMA becoming essentially a one-airline airport, and when FR is the one airline isn't an appealing prospect!
Fingers tightly crossed, not only for the airport, but for all the staff who's livelihood depends upon them, Baby will survive, and prosper.
