On an American Airlines Boeing 737-800, for example, the seat-rating site SeatGuru warns of several “bad” seats, denoted in red. They include all the seats in row 30, at the back of the aircraft. The reasons are obvious: Like Conway's, the seats in row 30 are next to lavatories and don't fully recline.
Designed around your needs. Your Economy Class seat on board the 737-800 NG is designed for your comfort throughout the flight, with ample legroom and adjustable headrests.
