The above poster isn't fully correct about regionals.

All regionals are NOT created equal, but as a former senior 145 FO flying for a crappy RJ operator I could consistently get 12-14 OFF with up to 7 days consecutive sometimes. I did quite a bit of overseas travel as well with my DL benefits. The pay was terrible, but the schedule was average. The guys with my same seniority on the -170/175 were getting 16-17 OFF with sometimes up to 9 days off in a row (I couldn't bid over).

Pay was crap, but this schedule was okay, especially since I lived in base.
