Sorry but I am with Katanapilot.
The current training is for those being re-trained from redundant hulls and the trickle feed of new A320's to LHR are easily enough being crewed from 757/767/737/747 ejectees.
The A320's replace the A319's that are going to LGW for which the training has been taking place over the last year.
Vacancy's? Nope.
Those currently in the company don't know whats going on at the moment so I don't hold out much hope for those in the pool.
Galley FM has, obviously, struck again.
