This is the thing.. Jet2 have already made it known they would like to get in to LGW, so unless anything has changed those issues you highlight (with the possible exception of slot shortage) are clearly not insurmountable.
Agree regarding SEN. Seems far too close to STN, although with the proximity to London stranger things have happened. Still, Jet2 employ a cautious approach to growth and this is one of the many reasons that they have done so well so far. You don’t generate revenue the way they do by competing with themselves. If they are to pursue growth at smaller airports then I think there are a few others they would look at first.
Cool, understood - If Jet 2 do want to go to LGW then I could see that now as they have overtaken TUI as the #1 UK's Tour Operator and they (Jet2) do not
as yet fly from Gatwick ! -
So they would be going head to head with them (TUI)
Risky, possibly the biggest risk that Jet2 may ever do to now.
