Jetliners are commonly used by commercial airlines, making air travel accessible to millions of people worldwide. Most jetliners have a spacious cabin with seating arranged in rows, and they often include amenities like in-flight entertainment and refreshments. Popular models include the Boeing 737 and the Airbus A320, which are widely used for short to medium-haul flights. Jetliners play a crucial role in global transportation and tourism.
