Rosters depends on the type but the 737/320-ish fleets have slavelike rosterings if you are used to more than 9 days off a month
The 321 is used for little longer flights so you might get less of the domestic flights and the "open duties"
The girls are very tacky, their parents will rule your life and they will cost you everything you will ever own. Not very beautiful or english speaking either
Forget about freeing willy unless married
