Jetliners are large commercial aircraft designed for transporting passengers over long distances. They are powered by jet engines, which allow them to fly at high speeds and altitudes. Jetliners typically have a spacious cabin with rows of seats, restrooms, and sometimes in-flight entertainment systems. These aircraft come in various models, such as the Boeing 737 and Airbus A320, each with different capacities and ranges. Jetliners are essential for global travel, connecting cities and countries, and are operated by numerous airlines around the world, making air travel accessible to millions of people each year.
