All a very interesting discussion, I agree with a little of both sides...
But I agree more that no 'list merger' would accomplish the desired results for the RJ guys.
Go the UPAS way, get your letters of recommendation and use the time till you're called to learn all you can about their interview process.
I left the military with over 6000 hours of C-141 and C-17 time (still in the reserves though to make Atlas livable) and I wait for the Delta letter, the UAL call and the AA letter/call. It's been right at 12 months so they should start for a WASPY guy like me.
While I wait, I study, talk to my buds who are there and keep myself as sharp as possible till I get the opportunity to 'talk my way' into that career job.
Best of luck to all you regional guys, The ones I've jumpseated with were very professional, I'd be happy to FO for any of you at the 'bigs'!
