I heard 80 pilots required for the 777 fleet alone ... and show me anyone with THAT type rating who's looking for a job at the moment? Same goes for the 744.
They'll obviously have to lay on type ratings for the majority of people that go onto those fleets at least.
The interesting thing will be the LCCs, whether captains are willing to jump ship and join the bottom of the BA seniority list, and a lot of the FOs will have a dilemma as well, in that many of them are still shouldering the bulk of the £20 grand loan they took out to get on board with Easy / Ryan / Excel / BMIbaby / Astraeus ... are they willing and able to jump ship, knowing that they'll still be paying off that type rating for years to come and they'll probably get a command in 3 years with their existing LCC as opposed to 10-15 with BA.
I would imagine that regardless of their seniority, most of Mytravel will have a CV in pretty quickly, none of those people can be feeling too secure in their jobs after recent events.
