Yay! I changed K's flight to next Wednesday. It got very interesting when the woman from US Airways asked for the credit card, and I gave her the info, and she asked to talk to me, thinking I was K, and I (me) had to give permission for the card to be charged. Naturally, I handed the phone to K, mouthing, "You're me" and gesturing wildly.

I think I need to lie down...
