I was talking to a buddy of mine that started working for SWA about 18 months ago (I've been with FedEx about 14 months), and he said he hadn't worked this hard since he was a FAIP (First Assignment Instuctor Pilot for you non-AF types), and it was beating him up. I have to say I've seen a couple of crummy trips, but it was just a couple, and I've never felt like punching a package for saying something stupid after I've been busting hump. I've talked to several PAX carrier crew dogs at the hotels and some of their stories amaze me. Good luck with your decision!
