Nothing finalized yet, but most probably we will see at least initially only 737 pilots on the 787 while the A320 pilots can get on the A330. Both fleets are planned to be flown in mixed fleet flying, the airbus fleet already does that and the authority just granted the approval to fly 737 and 787 after an 8 day CCQ in mixed fleet flying as well. Who gets on it will be decided by seniority.
