apples to ornages, I have flown at both regionals and frax, frax blows regionals away, from salary, crew food, hotels, rest, frax pilots alomost never sit in a FBO all day. Every other flight is empty to get another owner 3 to 4 legs a day is my average. Good luck, I think you will find frax much more rewarding in many ways then regional flying.
as far as the 7n7. its feast and famine, 7 days on is tough, but there is no commuting on your time, your first and last days are spent in a large part to the company airlining you around, and the 7 full days off are sweet, its a vacation every other week, I get to do a lot with my family, and with the 3 weeks of vacation, that 21 days off 3 times a year, 23 weeks on the road in a year
