Iver, the Boeing guys would have you believe that they will be required to provide their unique cocktail of Seattle based excellence make this new aeroplane a success. The A330 guys are convinced their wealth of ETOPS time will be essential. Both of these groups become more adamant the longer they stand at the bar, the truth is both parties cry themselves to sleep in the hope of escaping their rostering nightmares.
The aircraft most immediately leaving are the A346's so it would make sense the crews are drawn from there, but sense and pilot establishment do always make good bedfellows, so expect a substantial amount of cross training and passed over SFO's not getting Passover pay. In theory by Q3 2014 all Airbus pilots should be tri-fleeted. But 5 bucks and one cost saving initiative says that won't happen.
