Last year I signed up for 2 SW credit cards yielding 100,000 points. Last year I made Million Miler on United (giving me no reason to fly them again). Normally, I would have booked a planned biz trip on UA paying for my ticket. With my recently found SW wealth, I decided to use my miles for a trip LGA/LAS. Long story short, I cancelled my SW ticket do to a variety of issues. I was able to go to my SW account, cancel the ticket, and have the points returned to my account without any fees. Kudos to SW for allowing this. FYI, Darius at http://millionmilesecrets.com/ seems to have the definitive answers to all SW questions.
