Looks like I might be on a / the densified A321 next week LHR-CPH on Tuesday morning. Row 9 (the enormous leg-room exit row) is now Row 10 and it goes to row 37 which I think is a good giveaway. Anything I should be looking for specifically??
Actually, having looked at the ba.com seat map and the Expertflyer map, it seems that for the Door 2 exits, then Row 9 (2 seats) is ahead of the exit and Row 10 (3 seats) behind, so Row 10 should have the big legroom - but for Door 3 exits, Row 23 (2 seats) is behind the exit (so might have the big legroom), with Row 24 (3 seats) having limited legroom, despite being marked as an exit row as well.
I think from memory, the 2-seat rows used to be the longer-legroom seats at Door 3 before the previous round of densification.. is my memory right??
