Commercial airliners are large aircraft designed to transport passengers and cargo over long distances. They are operated by airlines and can carry anywhere from a few dozen to several hundred people at a time. These planes are equipped with comfortable seating, in-flight entertainment, and amenities to ensure a pleasant travel experience. Airlines like Delta, American Airlines, and Emirates use commercial airliners to connect cities around the world. The planes are built to be efficient and safe, with advanced technology that helps pilots navigate and manage flights. This makes air travel a popular choice for both business and leisure travelers.
