I have been in the military now for 8+ years and flying for most of it. I currently have 2500 hours // 1500 PIC in heavy jets and I am able to get out next summer. I figure I will pick another 400 hours by then (nearly all PIC). I am thinking about getting out and trying for one of the airlines. I saw pre 9/11 figures showing if you got out all the way up to 14-15 years it was better than staying in the military, I figure those numbers are not standing up anymore.
What do people recommend now in regard to staying in or getting out?

What are the advantages/disadvantages of an airline like SWA vs. UPS/FEDEX?

Due to the whole job insecurity thing I have considered staying in except for the very discriminating factors that I don't like it anymore, I am sick of moving (next one will be OCONUS with two young kids), and the bonus sucks. What do people on the other side advise?
