You are probably correct on the location of the limited or no recline seats.

But if the seat pitch is the same on the newly configured leather seating 319 and 318 planes, you should be OK. Pitch was reduced when the older fabric seats were replaced with the new leather seats, and it still seems fine, due to the fact that the "thickness" of the new seat is less. The seat in front of you can recline fully with minimal impact on your area, as compared to seating in other "legacy" carriers; at least that's my experience.

If the 320 is different, we will all have to wait for seat guru or other posters to give us their impressions.
