always nice to see something like this "behind bars" I guess
normal airline schedule/roster is 15 days on, 15 days off, maybe 2 days stby. If you work for a charter company or mixed schedule and charter it is even better: 12 days on and the rest off, roster in advance and maximum 1 change per year unless youself need to change it in case grandpa dies
and you need 3 more days off (paid).
