Swiss (LX) uses the same row numbers on their A319/320/321 fleet. The A319s have rows 1-16; 29-36, the A320s have rows 1-17; 26-36 while the A321s has rows 1-39. (None have row 13, which is silly.)
This idea minimises reseating for aircraft upgrades, and makes it easier for equipment downgrades.
They haven’t continued this idea for the C100/C300 though. Maybe it doesn’t work as well as hoped.
