I worked for a smaller ACMI before Atlas, we were two weeks on, two weeks off. Just domestic stuff. Atlas owns you for 17 days a month. They've closed their Stansted crew base but even with CONUS crew bases, you may have to travel on day "zero" and not get home till day 18. Plus the company can extend you. Like most pilot jobs, if you live in base it's not bad, the commutes can hurt. I just planned to be gone 2/3 of the month.
