BA have configured their A320 family fleet to have 30.0 to 30.4 inches of pitch in the first 8-14 rows, depending on aircraft type and configuration. That's the maximum number of Club Europe rows they'll sell. If the curtain is further forward, as is usually the case, then the lucky economy occupants of those rows get more legroom, plus slightly better charging facilities on most aircraft (e.g. AC plugs rather than USB sockets, 60W USB-C vs 15W).
