Even the A320 ?!? I would think that the A320 would be flown by one pilot group, and the 330/340 would be flown interchangeably by another pilot group (w/ differences training).
But the A320 is a narrowbody, and much smaller compared to the A330/340 (both comparable in size).
Are you sure GF will soon have only one pilot group flying all three A320/330/340 interchangeably?!?
Thanks!
