FallDisney,
It depends on what type of ticket you bought. The least expensive, promotional fares with restrictions are normally non-refundable, which means you could only get credit toward another flight. If you bought the more expensive refundable kind, you can get the $ refunded to your credit card. Call 1-800-IflySWA with your confirmation number and they can tell you what you've got.
IloveFH, you actually don't even have to put a RR# in there at all so I'm sure the person who is the member can make reservations for someone else. I mean, I'm a member but my daughter isn't and I bought her ticket. The RR member doesn't get credit for the tickets they buy - only the actual person flying does. But the form where you put the code in asks for the code on the first page, and then calculates the fares from there, so I really don't think you even have to be a RR member to use the code. In fact, I'm sure of it. I cancelled my original reservations and rebooked using the code, and I know I did not put my RR# in on the last page where it asks for passengers. I know I didn't because I was freaking trying to get the new reservation set up before all the seats were gone. I'll just show my RR card when I check in.
