At ABX you typically cannot hold a day trip unless super senior. The hub turns average to about 4 hours. Some longer some shorter, I have actually had a 6hr 30 minute hub turn in ILN. I was able to drive home 45 minutes one way, sleep in my own bed get 4 hour sleep, wake up shower and drive back and show at the plane an hour before push. That is way to long to be stuck in Wilmington. Agree with the not much to do. Eat, sleep, computer, watch TV or work out at the fitness center. Mostly only two legs a day, one in one out. We do have some multi leg trips. but no more than 2 in 2 out.
It is tough to get above guarantee on a typical flying line. 767 does have some lines over guarantee but fleet wide not the norm.
We have about a week on week off type schedule. We get 15 days off a month if a line holder, 14 days off on reserve. You start your block of 7 or 8 days on (those include days at a hotel for a 36 hr layover and the 3 or 4 day weekend trips.) On your weekend layover you can do what you want. You can jump seat home, hang out in hotel or do whatever, just be at the plane Monday night for the trip back in to ILN. If you call in sick for the inbound trip you had better be sick and not stuck trying to get back to the plane. That is a good way to get 30 days off (without pay).
Sorry cannot answer accurately the international stuff. We have a MIA base and are starting a KIX (Osaka Japan) domicile. Each base is staffed by international pilots. Same scheduling parameters apply. 15/14 days off a month with blocks of time averaging to about week on week off.
