It's a good pay gig for the first two years, especially the first year. Pay rate goes from $77/hr to $137. Third year w/b, or 6 yr n/b FO pay, catches up with 190 CA pay.

Next question, with zero 121 time do you want to upgrade in six months? Guy who's flown 121 before? Sure? No 121 experience? Single seat guy? Might be biting of more than you expect.
