My only OpUp was a good one. I was one of the first coach passengers to board, sitting in the exit row of an AA 777 from JFK-LHR. As the plane filled up, I was surprised to see the other exit seat wasn't taken. Once everyone was seated, an FA came up to me and asked if I was willing to switch seats for a couple whose seats were soaking wet. I agreed, and she lead me up through J to a seat in F.
