If you travel (me: not too often), this is a nice guide to consult before booking your plane ticket and choosing your seat: Welcome to SeatGuru! Your Guide to Airplane Seats and In-flight Amenities.

Choose the airline and the class of plane and then hover over the color-coded seats to see any pros or cons (e.g., does not recline) to the various seats.
