I forgot about code share partners. Yes, you get some benefits on codeshare partners, but the costs vary (a little higher, but not bad). You also get ID-90's. You can buy 90% off fares on any airline! SWA only charges you $25 per flight. Of course, there has to be an empty seat and you travel after all the employees of that airline get on. I did Honolulu to Maui on Aloha and got bumped four flights in a row! I had a buddy travel out of Orlando and she got stuck there three days! I told her to take the flight with seats, but she didn't listen. The flights are so full to popular destinations, I've had many vacations that I drive now. I also plan my vacations for off-season, so I can fly.
