Not to thread hijack, but here's the similar decision I'm trying to make:

I've been at a regional for 3+ years flying the CRJ. I have approx 4,000 TT and 3,000 pt121 SIC. I'm scheduled to get furloughed 11/1.

Do I:

1.) Take the furlough and await recall at said regional.
2.) Accept a class date with AE (conditional offer already) and surrender previous seniority.
3.) Accept a job offer flying Challengers (65K starting, 1-2 yr upgrade, 30% international overseas trips, up to 30 days on at a time).

The QOL issues asside, my main concern about taking the corporate gig is that I wouldn't be able to get back into the 121 world without once again starting out at a regional. Everyone seems to think that PIC is numero uno, but how often does a corporate capt go to a legacy? It seems I see more Regional FO's getting hired at Delta than anyone else these days.

Regards
