Which airline has the greatest economy class seat pitch in 2026? This is a very difficult question to answer, as in the real world, it varies within an airline. The seat pitch can vary depending on whether the aircraft is for short-haul flights or long-haul flights, on the type of aircraft, and on whether the airline is rolling out a new cabin configuration or not. If an airline is introducing a new cabin configuration, then the seat pitch varies depending on whether that particular aircraft has been refreshed or not.
