AA,
It isn't that we are thin-skinned...it however speaks volumes about those that would have never looked at any freight-dawg outfit even if that were the last job in the world (and that includes FDX and UPS, if you can believe that...don't know what it is about flying pax at UA, US, jetBlue, etc that turns them on...I'm so over that scene).
That said, I hope that your new-found airline-world-view will serve you well...until FDX and UPS call you though, if you need to find work flying big airplanes freight-dawg outfits might be the only game in town.
As for the legacy carriers, I can't imagine going to ANY of them right now...with SWA as a possible exception. But, damn those boys work hard flying 3 legs a day!!
Good luck...
