^^^ I jumped ship too (not at a legacy, though), and this is exactly how I felt about it. But different strokes for different folks. I'm happy, but I have plenty of buddies that wouldn't be.
IMO, anyone making blanket statements about corporate vs. airline is simply trying to make themselves feel better. Lots of good corporate/135 gigs. Lots of bad ones. Lots of good airline gigs. Lots of bad ones.
