1) The best "on time" records in the industry.
2) The best luggage handling record in the industry (your bags actually follow you where you are going).
3) The ABSOLUTE best safety record in the industry.
4) Voted the most friendly service in the industry 5 years running. (Business Travelers Association, 1997 through 2001).
SWA also have a custom design to all of their aircraft in the area of cabin seating. There is NO first class on SWA flights, never has been, never will be. In the cabin, usually in the very front and the very back, there are 6 seats on each side of the isle that face each other. The leg room on these seats are usually much better than the standard seats (besides, they are more fun, you can meet lots of nice folks). I'm 5'11 and about 210, I have never found SWA's seats to be confining, especially in the afore mentioned areas. SWA has a general seating policy--first come, first serve. Put all these factors together with the fact that flight crews are sooo friendly and accomidating and you get easy ways around this.
I will be willing to bet that SWA will make this fun, and profitable. I don't know how they will do it, but I'm sure that they will do it. As I said, I am a stockholder, and I have a lot of stock that I've had for a long time (my retirement). Have faith, and take SWA, you'll laugh and have fun.
