There is no single answer to your question, it depends on who you work for and what you fly and where you are based. My last employer was long haul freight-go to work, fly, layover,fly layover, fly for 17 days then go home for 13 off.
now I work at a pax carrier. On the widebody it was fly out for 2-5 days then home for a few: on the narrow body it is out and backs everyday. work about 14 or 15 days a month off the rest.
Seniority at your airline really makes a difference on the schedules you fly, which is why some people prefer to fly as a senior fo and have a great schedule as opposed to a junior captain who makes more money, and may have a far worse schedule.
