Recruitment was planned for Autumn 2011 due 787 deliveries in Jan/Feb/Mar 2012. Whether that get's delayed due to the current production problems, who knows?
There were rumblings of a small amount of recruitment Spring 2011, probably via CTC or the other Intergrated schools. Figures depend on how many leave for BA.
Expect, when it does happen, to be summer only contracts, most likely not permanent, and forget anything you see on PPJN re Ts and Cs. They're already dropping hints about a new contract for joiners with lower salary, possibly no increments and less days off per month.
Also expect NCL, CWA and possibly EMA/BHX. LGW and MAN are full.
Everything at the moment is about cost reductions and reducing the summer/winter imbalance
