Where would Jet2 get all these aircraft from?
They are basing 2 more at BHX, 2 more at MAN, 1 at LBA, at least 2 more at STN and that doesn't take into account any aircraft retirements (G-CELI looks to be gone this month for a starter).
Then there are rumours of a BRS base too which would be either 2 or 4 aircraft, now SEN at 4. That's 16 aircraft to find for next summer off the bat, without even considering of any other bases such as BFS/EDI/NCL etc get an extra aircraft too,....
