A narrow-body aircraft or single-aisle aircraft is an airliner
arranged along a single aisle, permitting up to 6-abreast seating
in a cabin
below of width.
In contrast, a wide-body aircraft
is a larger airliner usually configured with multiple aisle
s and a fuselage
diameter of more than , allowing at least seven-abreast seating and often more travel class
The highest seating capacity of a narrow-body aircraft is 295 passengers in the Boeing 757–300
, while wide-body aircraft can accommodate between 250 and 600 passengers.
2-abreast aircraft seat typically 4 to 19 passengers, 3-abreast 24 to 45, 4-abreast 44 to 80, 5-abreast 85 to 130, 6-abreast 120 to 230. For the flight length
, medium-haul aircraft are typically the Airbus A320
and Boeing 737
, while regional airliner
s typically cover short haul.
Historically, beginning in the late 1960s and continuing through the 1990s, twin engine narrow-body aircraft, such as the Boeing 737 Classic
, McDonnell-Douglas MD-80
and Airbus A320
were primarily employed in short to medium-haul markets requiring neither the range nor the passenger-carrying capacity of that period's wide-body aircraft.
The re-engined B737 MAX
jets offer 500 miles more range, allowing them to operate the 3,000 miles transatlantic flight
s between the eastern U.S. and Western Europe, previously dominated by wide-body aircraft.
Norwegian Air Shuttle
, JetBlue Airways
and TAP Portugal
will open up direct routes bypassing airline hub
s for lower fares between cheaper, smaller airports.
3,300-mile range is insufficient for fully laden operations and operates at reduced capacity like the A318
, while the Airbus A321LR
could replace the less fuel efficient B757
s used since their production ended in 2004.
Boeing will face competition and pricing pressure from the Embraer E-Jet E2 family
, Airbus A220
(formerly Bombardier CSeries) and Comac C919
Between 2016 and 2035, Flightglobal
expects 26,860 single-aisles to be delivered for almost $ billion, 45% Airbus A320 family ceo and neo and 43% Boeing 737 NG
By June 2018, there was 10,572 Airbus A320neo and Boeing 737 MAX orders: 6,068 Airbuses (%, 2,295 with CFMs, 1,623 with PWs and 2,150 with not yet decided engines) and 4,504 Boeings (%); 3,446 in Asia-Pacific (%), 2,349 in Europe (%), 1,926 in North America (%), 912 in Latin America (%), 654 in Middle East (%), 72 in Africa (%) and 1,213 not yet bounded (%).
Many airlines have shown interest in the A321LR or its A321XLR
derivative, and other extended-range models, for thin transatlantic
