We are also looking at Premium Economy seats for a flight to Madrid in October 2023. If you go to seatmaps.com you can select the airline and airplane you are considering and it will give you all the info on that flight. It will show you the seat configuration (like 2-4-2 or 3-3-3 etc), the seat width, seat recline, and seat pitch (distance from seat in front of you). It’s helped me immensely in narrowing down my selection of flights I’m interested in.
