Narrowbody aircraft are a type of commercial airplane designed for short to medium-haul flights. They typically have a single aisle and can seat between 100 to 240 passengers. Examples of narrowbody aircraft include the Boeing 737 and the Airbus A320, which are widely used by airlines around the world. These aircraft are known for their efficiency and versatility, making them ideal for domestic routes and regional travel. Their design allows for quicker boarding and deplaning, which helps reduce turnaround times at airports. Narrowbody aircraft play a crucial role in connecting smaller cities to major hubs.
