Each of gates 15 and 16 can also simultaneously handle two single-aisle aircraft as "15L" and "15R", or "16L" and "16R" respectively.

Demolition began in 2013 to make way for a new and bigger Terminal 4, designed to cater mainly to budget carriers and regional airlines that operate single-aisle aircraft.

The airline said it had agreed to terms with Airbus for 22 of the long-range A350s, part of a 92-plane deal that includes 60 A320 single-aisle aircraft and 10 A330s.

Like the A320, the 737 is a single-aisle aircraft suitable for short-haul domestic routes.

With the A380, Airbus will be able to match Boeing's product line model for model, from 100-seat, single-aisle aircraft all the way up to the 747.

JetBlue flies new Airbus A320's, a single-aisle aircraft, and offers one class of service.

In January 2010, John Leahy, Airbus's chief operating officer Customers, stated that any all new single-aisle aircraft is unlikely to be constructed before 2024/2025.

Currently it produces versions of Tupolev 204 and 214 aircraft, rather unsuccessful version of Boeing 757 single-aisle aircraft.

Minimizing time on the ground, especially on shorter flights that use single-aisle aircraft, means the planes can get back in the air faster so they can make money.
