"An aircraft seat map or seating chart, is a diagram of the seat layout inside a passenger aircraft. They are often published by airlines for informational purposes, and are of use to passengers for selection of their seat at booking or check-in.
Seat maps usually indicate the basic seating layout, the numbering and lettering of the seats, the location of the emergency exits, lavatories, galleys, bulkheads and wings. Airlines which allow internet check-in frequently present a seat map indicating free and occupied seats to the passenger so that they select their seat from it." [Aircraft seat map. Wikipedia]
