The A350 orders are for 2016 onwards, but the 777-200ER's would be for late this year/early next year. Our Management don't want to miss out on any business opportunities...
This would definitely make a difference to command courses for next year (should it happen), since there were only about 40-50 expected for 2011 (plus JFO upgrades and SO recruitment, etc)
The more stress that can be put on crewing the CX jets across the network, the more potential leverage that can be applied against improvements to the contract(s).
