Airline seating refers to the arrangement of seats within an aircraft, designed to accommodate passengers during flights. Seats are typically organized in rows, with configurations varying by airline and aircraft type. Common layouts include 2-2, 3-3, or 2-4-2 seating, depending on the cabin class, such as economy, business, or first class. The design of airline seats includes features like adjustable headrests, tray tables, and in-flight entertainment systems. Airlines often provide different seat options, such as window, aisle, or middle seats, allowing passengers to choose based on their preferences for comfort and convenience during travel.
