On most modern wide-body aircraft (like the Airbus A350 or Boeing 787) in 2026, yes, the last row of Premium Economy reclines fully. Unlike standard Economy, where the last row often hits a bulkhead wall, Premium Economy cabins are usually designed with enough "pitch" (space) to allow the final row the same range of motion as the rows in front of it. Some airlines, like Air New Zealand or Lufthansa (Allegris), use "shell seats" where the seat slides forward within its own frame, ensuring that the last row’s recline never impacts anyone behind them—because there is no one behind them except a curtain or bulkhead. The main downside of these seats is not the recline, but the potential noise from the galley or the proximity to the lavatories, which can be busy during long-haul flights.
