In this day and age, I just want a seat that I don't have to elbow someone for. The concept of standing in line just to get a seat, I hate. I have flown Allegiant a couple of times and Spirit a couple of times, and even if you don't pay for a seat, the computer assigns you a seat. To me, that's infinitely better than what SW does. That said, on those airlines, I generally just pay and get an assigned seat....
