I did a search and didn't see anything on this so thought I'd start a thread. I have a trip coming up in early january with two segments on A319s and on the outbound segment the rows are showing up as 1-2-3-10-11.... and so on, with the the Y bulkhead being row 10 and the exit row being row 15, but on the return segment the rows are showing up what I'm used to, 1-2-3-4-5... and so on, with the Y bulkhead being row 4 and the exit row being row 9.

Anybody else seeing anything similar to this? I figure it is just an alignment to make all aircraft have the Y cabin start in row 10 but it could throw people off who are used to requesting certain seat numbers.
