SkidMX, the end of lease for the Airbuses sounds far away. Rumor in Tfly was that the "end" was around 2008/09. I would bet a lot of money that the Airbuses will go sooner or later. There are more than 35 737s in order by the TUI group. At least 25 of those are going to the UK. The first three are here already.
Westie, there is no 737/767 combination planned in LTN. In any case, it sounds like LTN will be overfilled with the STN Tfly pilots. Having said that, the airframes are increasing by one for S08, but still I doubt there will be any room for people to move there.
