Row 2-7 has 32" pitch (supposed to be bizz and eco extra) and row 8-24 has 31" (except for EE row 16 and 17).
Not much of a difference but if you are travelling in P and if your knees has a tendency to touch the seat in front it might be a good idea to look for a seat up front if available. Often there are only a few rows reserved for C and Y but it of course depends on route and departure time.
