Passenger planes—also known as airliners or commercial aircraft—are airplanes designed to transport people safely and efficiently across short, medium, and long distances. They play a vital role in global travel, business, tourism, and cultural exchange, shrinking vast distances and making the world more interconnected than ever before. Passenger planes are powered by jet engines or, in smaller aircraft, turboprop engines. These engines generate thrust to move the plane forward at high speeds, while the wings create lift—an upward force that allows the aircraft to rise into the sky.
The balance of lift, thrust, weight, and drag is what keeps a plane in controlled flight. Modern airliners include advanced navigation systems, weather radar, autopilot functions, and communication tools to ensure safe travel. A typical journey begins long before takeoff. Travelers check in, pass through security, board the plane, and settle into their seats. Once onboard, flight attendants provide safety instructions, assist passengers, and serve meals or refreshments depending on flight length. On long flights, entertainment systems—featuring movies, music, and games—help make the journey enjoyable.
