What is a narrow body aircraft?

A narrow body aircraft, also known as a single-aisle aircraft, is a smaller-type aircraft that is often used to operate short-haul international flights and domestic flights. A narrow body aircraft can carry as little as 4 passengers up to as many as 300.


Wide body planes usually just have the one cabin — Economy Class. But, sometimes it can have an additional Premium Economy and Business/First Class cabin.


Narrow body aircraft only have one aisle, which is where the alternative 'single-aisle aircraft' name originated from. A narrow body aircraft will have between 2–6 seats per row, which are split by the aisle. A typical seat formation for a narrow body aircraft in Economy Class is either 3 x 3, 2 x 3, 2 x 2, 1 x 2 or 1 x 1. If the aircraft does have any additional cabin classes, there will usually be less seats per row. However, there are exceptions to this. For example, in Premium Economy or Business Class, some airlines will have the same number of seats per row but leave the middle seat vacant to give passengers more room.

Narrow body aircraft are used for commercial passengers flights and cargo flights by airlines all over the world.
