I've just had a seat change on a BA flight from WAW to LHR on 31 December, and I am guessing it's the A321neo? It has 37 rows, a single emergency exit row 16 and then a double emergency exit row 26/27 with the double seats in row 26. I've not seen this layout before, and wondering whether to go for row 16 or row 27 (which I am guessing has more leg room). Will this aircraft have the horrible thin seats towards the back?
