It better be a damn sight more than Wizz and TUI as that's what was there previously and the operation lost a fortune. The problem has got to be who else is there.
I doubt Jet2 with the proximity of Leeds. EasyJet's business model seems to have shifted more towards larger airports these days. Ryanair have aircraft shortages already and new base option limited.
So who does that leave ? Would like to be wrong and call me pessimistic, but I really cannot see airlines queing to get into a newly opened DSA and then we're back where we started....a cash burner.
