Well that tells us a little more; Falcon Air doesn't have the best reputation in the world for "doing right by their pilots" but then again, neither does Pinnacle. They will break the contract in a heartbeat if you let them - a lot of that going on the last 48 hours with the snowstorms.
I'd love to be back on the 72, even had an offer to do it overseas recently, but job security is harder and harder to come by and I know at least here will be stable for the next 3-5 years. Can you say that about Falcon?
I think Falcon made their remaining 72's RVSM compliant so you probably don't have to worry about them going away anytime soon, and 700 hours of flight time isn't that much less than the 900 or so you can realistically expect at a regional and that's busting your tail. What I'm getting at is that even IF you come to a regional and IF you upgrade in a year, within three years you'll be sitting on approximately 3,500 - 4,000 hours total time, 1,000 to 1,500 PIC Turbine 121. Sounds good on the surface, but think about who you'll be competing against.
As the market thins itself out (assuming no major carriers fail), Continental will start hiring sometime late this year / early next year. Northwest MIGHT have everyone back by the end of this year. Realistically no BIG hiring booms for another 3-5 years (optimistically). So unless you have an "IN" guaranteed somewhere, all the rest of us regional guys with anywhere from 6,000 to 10,000 hours total time, 4,000 to 6,000 PIC Turbine / Jet are going to be your competition (in other words, guys with twice your experience).
So do you want to leave a decent-paying 727 gig for a crappy-paying regional and start all over again or do you want to hang out for three years, make CA on the 727, and do you gig there as you apply for "bigger and better things"?
Tough call, only you can decide what's better. Good luck.
