I checked a few friends rosters because I wanted to see for myself if the other fleet was worth bidding.
15 pilots both 777/AB DEC/NOV bids
Dec total days off 147, Nov 97
more Vacation awarded in DEC than NOV
most days off ( not including rest days ) 14 and that was an AB guy
some guys only getting 2-4 days off in vacation months and they were 777
No idea which bid groups, know for a fact that some know the bid system very well
