from what I see it is more often hell than heaven
I think you'll find the folks who are in the "heaven" job don't tend to go on forums to vent & grumble, so you just don't hear about them as much.
To the OP, I'm an airline to corporate convert, & absolutely loved it. If you are prepared to roll your sleeves up & get involved with all the areas you never normally see in the airlines, you'll do fine. Not every job is perfect, but when you do find one that is the right fit, you won't be sorry to took the step.
