I also prefer Southwest. So much so that I even opened up a Southwest Visa card so I get points to fly. I like that they're more "real" (flight attendant dancing briefly before the flight to someone's cell phone ring) and they're easy to get to (MDW) and they're relatively inexpensive. I REALLY enjoy that they opened up the MDW-MSP corridor this past March, as I have family up there and the 7-hour drive through Wisconsin on sleepy, 2-lane roads is a bitch. And they have killa chinchilla deals - I presently have a RT ticket to MSP for $80.21. It would cost more in gas to drive up there!
I generally enjoy flying. I'm surprised when I find people who don't. Maybe it's just because I don't do it often, so it's sort of novel.
That said, damn...I need to fly Virgin Atlantic, Upper Class. WOW.
