CKid hit most of the current points. Even coming from the 767 on another now defunct ACMI carrier where we were on the hook for 14/28 or 28/56 days, which equates to about 15 days a month, most of our pairings consisted of something like 8/6/6/8 or 10/9/9/10/9/10 with some 14/14 Leipzig pairings thrown in. I will say that the extra days in a 17 stretch is really pushing it and makes for a long month even with the block of days off, and like mentioned above, with no real meaning of seniority, will not change as you progress. I used to do the same exact type of flying and like it but the extra couple of days a month makes a big difference for me. Not to mention the other stuff that has been said.
