Fargoo,
Obviously you have insight into the new orders not yet deferred no?
There are only a few new (3 more I believe after G-YMMM's replacement) 777 aircraft coming this year and nothing for next year at all. The company is desperately trying to delay the delivery of the 380 and the 787 delay is a 'god send' in disguise.
Add to that that the lead in time for training CC and FC are totally different. Whilst the training time for FC on a new aircraft type can comprise of months the same cannot be said for the CC who can be familiarised with the 'standard' cabin equipment and the 'standard' Airbus/Boeing door as the company see fit.
Why do we need the crews now when the aircraft are, at least, 18 months away?
