Had to post:

Years ago, 1990 when I was younger and not as well off (also single - between M), GF and I were in Narita and the line for check in was extremely long. I asked her to check us in and try and get exit row seats and I would go get something to eat. She said she was not hungry and told me to take my time and perhaps take a nap since the flight was hours away.

I came back after about 2 hours (I know, I know...I should not have left her for so long) and she said the ticket agent gave her (I am guessing the row number) seats 11C & 11D. I was a little upset that we were flying a "small" plane home to EWR.

We boarded and were directly to the "second floor" and did have exit seats but in FC.

All I can say is that I sweated it out until the plane started to taxi but the flight home was extremely comfortable.
