Thanks for the replies. I'm about to find out for real how they resolve the min days off issue. In Zulu time, I have 13 days off. Switching the calendar to LBT; I have 14 days off. Unfortunately, I think they will remove either the carry-in trip (7 days of carry-in) or the carry-out trip (2 days in Dec) and leave the 13 day mid-month trip which ends on the 24th (LBT). Ouch, Christmas Day in the AOC (no jumpseats 'til the 26th).
