Flew twice on these aircrafts (there is is more than one)
C was renumbered rows 1-4 but no real difference.
21 ABC does not exist.
Rows 22-23 are labeled "preferred" I don't know why.
The small galley between Y and C is gone, instead there are 21 HJK with plenty of legroom. Beware of 21H you are right across of the WC door.
28 Is the row before the exits - no recline
34 is the row of the first exit - no recline but extra legroom.
35 is the exit row.
