E190 has windows on every row but the new configuration of A319 (24 rows) and A320 (29 rows) has no windows in the last row. Finnair website is still showing the old seat map with 28 rows for A320 but I believe all of them have now been refurbished with 29 rows. You can find very detailed seat maps with correct window placement on Aerolopa website:
