I would look at who the carriers you want to work for are hiring.
AA hires ex-mil, and flow thru. This won't really change moving forward.
UAL hires a lot of regional guys, but the key is they have mostly been check airmen.
DAL is kinda all over the board. But the strongest candidates are ex-mil and check airmen.
SWA hires single seat fighter guys, and check airmen.
jetBlue tends to hire guys from all over. I got a call out of the blue, just a regular line guy, but many of them have been passed over. Again check airmen letter helps bigtime.
Spirit, as their deliveries wind down I think you'll see more F/O's getting called there.
Just some thoughts. AWAC is a good company, but personally I think you really missed the boat when you didn't jump to PSA or PDT. With upgrade comes the ability to become a check airmen, and in fast growing companies they tend to allow most anyone interested in it in. At AWAC, it was a tough nut to crack for many years due to no movement. With a check airmen letter you can pretty much write your own ticket.
Don't look at spending many years at a regional. Rip the bandaid off. You want to spend the majority of your time at your career airline.
