I sat in row 25 last year, when travelling on a reward ticket (I'd previously always been on paid tickets and, as a Gold holder at the time, got the forward cabin).

The flight was totally packed, as BA were running the "fly full fare CW, fly Concorde one way" promo at the time. I have to say that the last row was an oasis of civilisation compared to the rest of the plane. Fewer people milling about, a FS on hand most of the time and a little bit of stowage behind the seat.
