Tried to check in on line and I could not do it. Because I had minor kids with me. We were separated in our seats. I had to pay airport prices for my bag going back to Rockford I was not a very happy camper.

The plane was less than half full. It was nice to have my row and the row in front of me to myself. Glad I didn’t pay for a seat.
