If you pull the trigger, I'd live in RES domicile and commute to 121 work, because doing it the other way sucks. Ask me how I know. Work the hours for a bit, apply to a regional...that you can be domiciled close to home. Be careful of any bonus you take, as that may require an extended tour there. Get your 121 time, and keep your apps up to date. You're in a great place as of now...Hiring will be good for 4-5 yrs minimum. Obviously, seniority is everything at the major league, but since you're so young, it's gonna all be gravy at a later date. Many of the majors hire old dudes like me...I was hired when I was 45. Folks like me will be giving you a seniority bump in 12-17 yrs.
