Its been said many times before, its not a wise thing to do. What I can say that as an example you can expect 9 days off on the 380 fleet and work 92 hours. Some months you can get 13 days off and still work 90 hours.
Generally you'll work 90-100 hours per month.
PS...Don't forget the 5 year bond meaning that you have no choice but to like the hours.
