For info, here's my fairly typical December roster as an FO on the 744:
02-04 MCO
07-09 JFK
12-14 BOS
17-19 MIA
22-25 BGI
29-01 LAX
Apart from the LAX it's all 2 crew trips so plently of sectors but with only 2 days off between trips I'll be too spaced out to enjoy Christmas. I also commute to France which makes things worse.
