Passengers in seats adjacent to the aisle have the advantage of being able to leave the seat without having to clamber over the other passengers, and having an aisle they can stretch their legs into. Window seats are preferred by passengers who want to have a view, or a wall which they can lean against. Window seats are located at the sides of the aircraft, and usually next to a window, although some aircraft have seat rows where there is a window missing. Very wide planes such as the Boeing 747 or the Airbus A380 have ten seats abreast, typically in a 3+4+3 layout, although this layout is also sometimes used as a high density layout on aircraft normally seating nine abreast, such as the 777 or DC-10. On wide body-aircraft the center block of seats between the aisles can have as many as 5 seats on planes like the layout on some McDonnell Douglas DC-10 and Boeing 777 aircraft, although Boeing recommends the 3+3+3 over the 2+5+2 layout. Asymmetrical layouts also exist, the Embraer Regional Jets have 1+2 seating while the Douglas DC-9 aircraft typically feature 2+3 seating. The widest narrow body aircraft such as the Airbus A320 and Boeing 737 have six abreast seating in a 3+3 layout. On very small aircraft such as the Beechcraft 1900 there are only individual seats on each side of the aisle (1+1 seating). The number of seats abreast is affected by the aircraft width. DELTA AIRLINES SEATING - AIRCRAFT CONFIGURATIONS -Īirline cabins are frequently classified as narrow-body if there is a single aisle with seats on either side, or wide-body if there are two aisles with a block of seats between them in addition to the seats on the side.
