Flew Southwest Airlines two times before between Phoenix and LAX and once to Austin. Both flights from Phoenix to LAX were delayed one hour. Fortunately I usually plan for this sort of thing so I was OK with connecting to my international flight at LAX, but I'm sure others weren't so lucky. Plus, on the flight to Austin one of the flight attendants sang country songs and told inappropriate jokes about men and her husband over the loudspeaker for about 10 minutes-15 minutes. Some of the more "goofy" passengers actually seemed to enjoy "the show." But I prefer my airlines to stick to air travel and not comedy or music. Plus, what about those people that want to get some sleep or read? Why would they want to be subjected to this juvenile krap? Plus you can't select your seat before the flight. You have to stand in line like cattle at the gate in "boarding groups" and then when your group is called to board fight off others to get a good seat. I'm a big guy so I usually win, but what about the little people?! LOL. Plus, I don't like the stress of knowing I'm gonna have to do battle with others to get a decent seat.
For these reasons I haven't flown Southwest since 2008 and have only flown US Airways domestically.
