Flying out of Buffalo is great. Small Airport. We have stayed at a hotel across the street and just done a park and fly, they will shuttle you across the street to the airport. Holiday Inn Express is very nice.
What has worked for me is I cancelled my more expensive ticket, and rebooked. Then called 214-792-4223 and requested a refund to my credit card.
I have done this twice once when booking through SW directly and the other was all over the internet then I just called for the refund.
Don't take the first response which is usually you have to apply it to future travel or that they will refund after you fly. This has never happened to me I have always gotten the refund my first attempt but others have gotten these replies and jsut called back and gotten the refund... Maybe it depends on which person you get on the other line but it has always worked for me.
Hope this has helped, any other questions let me know
