Well, we finally got our bags back tonight. We tracked them during the day and saw they were moving after they arrived in Madrid. They were halfway to the hotel, and then around 4:00, we saw that they were back at the airport. We called United and talked to customer service in North America, and we don't know if she did something, but they were delivered to the hotel tonight around 9pm. Now we can actually get into some fresh underwear and socks, and I can show up in a different shirt in future pictures. Sweating in our clothes has not been fun, but we made do.
I did buy a Uniqlo linen shirt yesterday, but when I went to put it on tonight for the concert, it had so many fold marks and our wrinkle release spray was in our luggage, so I had to go with the same T-shirt I was wearing for the last two days.
