Narrow-Body Aircraft
Definition: A narrow-body aircraft (also called a single-aisle aircraft) is a smaller passenger airplane with one central aisle, typically used for short-haul and domestic flights, seating 100–240 passengers.
Narrow-body aircraft like the Boeing 737 and Airbus A320 family are the most common commercial aircraft worldwide. They feature a single aisle with typically 3+3 seating in economy. Business class on narrow-body aircraft is usually a 2+2 configuration with recliner seats rather than lie-flat beds.
For business class travellers, narrow-body aircraft represent a significant product downgrade compared to wide-body equivalents. While you’ll still receive premium meals, priority services, and extra space, the seat will not lie flat. On flights under 3–4 hours, this is perfectly acceptable. On longer sectors, it can be disappointing.
Some routes can be operated by either narrow-body or wide-body aircraft depending on the airline and schedule. For example, transatlantic routes may use a Boeing 757 (narrow-body) or Boeing 787 (wide-body). Always check the equipment type before booking business class. BookMyBusinessClass agents can identify routes where wide-body aircraft operate to ensure you get a lie-flat seat.
