A pre-flight safety briefing (also known as a pre-flight demonstration, in-flight safety briefing, in-flight safety demonstration, safety instructions, or simply the safety video) is a detailed explanation given before take-off to airline passengers about the safety features of the aircraft they are aboard.

A pre-flight announcement, formally known as the Pre-flight Safety Briefing, is a mandatory oral and visual demonstration required by civil aviation authorities (like the FAA or EASA) before every takeoff. It is designed to familiarize passengers with the aircraft's specific safety features and emergency procedures. The announcement covers several key areas: how to fasten and release seatbelts, the location and operation of emergency exits and evacuation slides, the use of oxygen masks in case of decompression, and the location of life vests. It also includes "final cabin checks" like ensuring tray tables are stowed, seatbacks are upright, and window shades are open. While traditionally performed live by flight attendants, many airlines now use sophisticated, often humorous safety videos on the in-flight entertainment screens. Even if you are a frequent flyer, you are encouraged to listen carefully because exit locations and safety gear can vary significantly between different aircraft models like an Airbus A320 versus a Boeing 737.
