Guys, a lot of you need to calm down. The airlines will be okay. jetBlue will be okay. Continental will be fine. airTran will survive. Northwest will make it through. I will say it again: THE AIRLINES WILL SURVIVE. Yes, they WILL suffer, but in 18 months, everything will be back to normal. I would not worry about the following airlines:
American/American Eagle/TWA, Continetal/Continental Express, Delta, Northwest, Southwest, jetBlue, Midwest Express, Frontier, USAirways, United, Alaska/Horizon, Vanguard, America West, airTran. The only airline I would worry about is National, though I still think they will survive.
