Narrow-body aircraft

Size comparison between an Airbus A320 (narrow-body) and a Boeing 777-300ER (widebody aircraft)

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 4 metres (13 ft) of width. In contrast, a wide-body aircraft is a larger airliner usually configured with multiple aisles and a fuselage diameter of more than 5 metres (16 ft) allowing more than 7-abreast seating and often more travel classes. 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.

Thomas Cook Airlines Boeing 757-300 are the most dense single-aisle layouts at 280 seats. [1]

Between 2016 and 2035, Flightglobal expects 26,860 single-aisles to be delivered for almost $1380 billion, 45% Airbus A320 family ceo and neo and 43% Boeing 737 NG and max. [2] Narrow-body aircraft with a range not allowing transatlantic or transcontinental flights are commonly known as regional airliners.[ citation needed]

2-abreast aircraft seats 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. [3]
