First time I was asked to switch seats in AA F a few weeks ago. Since I was travelling by myself, I said since it was the same row as well and I wasn't losing out on FEBO. Don't know why they asked even though they didn't talk to each other the entire flight. The seat condition of my new seat wasn't the greatest too but nothing major..
As long as I don't get last choice on meals, have less pitch, or have a big seatmate then I would consider it as long as I'm travelling by myself as well.
