You'll know for sure what the right decision is when you die. Seriously... ask any TWA, Braniff, Eastern, Delta, American, United, US Airways guy, etc....
I fly with a lot of captains at Fedex who tell me 20 years ago, all their friends told them they were crazy to stay at Fedex, and that they should leave and go somewhere better. A lot of the guys that told them that lost most of their retirement, and some even their jobs.
Fedex, SWA, and UPS do look good. Right now. Today. You just don't know till the dust settles and it's all over. So, spend time with your family, have other interests, and pray it all works out for you in the end.
