well got on the flight and had a brief moment of happiness when I saw the preferred seat headrest cover in row 14....
But then, as I slouched down I saw my knees getting closer, closer, closer, and yes.... The climactic event of my knees touching the seatback of 13D in front of me!
No preferred seats confirmed in row 14/15 on the A321 with 16J I guess.
However, I suppose it was a "preferred" location to get off the A321 first, as it is the plane where the onloading/offloading never ends!
For a rapidair, not a biggie, but now informed for longer flights.
Merry Christmas everyone!
