Nothing, and I mean nothing like flying a CRJ-50, CRJ-100, CRJ-200 (aka Barbie Jets). 1st class seat very comfortable. I like em. Only down side can be carry-on's. Can't remember which one of the bigger regional's that mine has a hard time fitting but it's one of them (it's big enough for my laptop and a days change of clothes), and with a laptop I really don't want to gate-check it.
