I'm on the 747 and my bid seniority in ANC routinely gets me a DH on the front end as to not burn days off getting to work. I have never been extended (although they have tried but only a few times) and I have never burned a day off getting home. I average 15 days off a month. Never less than 14 and occasionally 16. When I bang in sick or conflict bid it can be more which drops me to min guarantee with R1's being stuck on the front or back but i'd rather be at home regardless.

pm me for more details.
