Take a look at Jetblue's financials. They are in just as much trouble as any other airline out there. 17 out of the last 20 markets they entered haven't been profitable.
If they can't raise the fares AND keep their planes (2-3 new a month?) full, they are Independence Air in slow motion reverse. Most airlines are in trouble today. The people (er, posters on here) from Jetblue seem to refuse to believe that anything bad can ever happen to them there. That JB can do no wrong. It just ain't so. Even the mighty SWA isn't immune.
I have a lot of friends at Jetblue. Most of my friends/coworkers from Indy have found a home there. I don't want them looking for another job again. But the idea that Jetblue doesn't have some huge obstacles in front of it and it's nothing but good times ahead, is a little blind.
As far as FedEx and UPS, I agree with you 100%!!! That's as closest thing to job security as a pilot can find today. They shouldn't even be considered airlines, because what they do and what pax carriers do are on completely different planets.
On a small side note.. isn't amazing that a company that has 2 billion dollars in the bank is weary of being low on cash? What an industry....
