People are leaving because of a lot of things. There were many that after 9/11 realized how difficult it would be to take the pay cut. With all of the crap that is going on many are realizing that they can't afford not to take the pay cut.
The are loosing a lot. I know that even some of the CP's are looking at SWA and others. It makes sense. Unless this job will always come first and you do not care about your family, you will need to make this temporary at best. ASA is good for 3-5 years top. DO not get comfortable. If you are feeling yourself do that, go find another job.
