Oh, I am so, so sorry!!! I was recently about to fly AirTran because it was a little cheaper than Southwest. I just couldn't get comfortable with their cancellation policy (what if a kid gets sick or there is water in my basement or...really, I am actually an optomistic person)--so I spent a little more with Southwest.
Just try to take my father's advice..."Honey, it's too far from your heart to be serious." He always helped put things in perspective.
And it sounds like no matter what, you STILL will be able to go see the Mouse!
