Thanks for sharing the article. My flights to/from Vegas are short, an 75-80 minutes or so. Have never slept on a flight to Vegas - the passengers seem to be a bit amped up, so it's noisier. I'm excited myself, so probably can't fall asleep even if I wanted to. The return flight, though, I've slept for about a half hour. The mood on those flights is a bit somber - go figure.
I always choose a window seat (even on the short flights I take there are people who have to use the toilet). Also, SWA doesn't have drink carts, but it's more the passengers who either swing their big bags down the aisle or can't walk a straight line down the aisle. No aisle seat for me.
