Is there any feedback on the Y cabin, specifically any rows with missing windows? Traveling on a couple of these with our two little kids (2 and 4), and learned the hard way what happens if a window is missing after booking Row 12 on the regular A321 twice (although just looking at the regular Y cabin for these flights). Currently have rows 18, 21, 22, 23 (don't care about no recline in 18, unless there's something else weird with that row).
