Shared a car into work with 2 Recruiters last month - Was told all foreseeable recruitment will be for 330 FO's.
I'm guessing that DEC 's will predominantly go to 777 (note boeing experience required for DEC applications) thereby reducing 777 upgrades for current FO's that will come to the fore in a few years time.............thereby new hires needed for 330 whilst current 330 FO's transfer to 380.
