What should passengers do with their coats and jackets before screening?

Passengers should take off their coats and jackets before screening because these items are subject to security screening procedures. Removing outer garments allows security personnel to properly examine them for concealed items and ensures that all items go through the x-ray machine. This practice is essential for maintaining a high level of safety and security in airports, as it minimizes the risk of hidden weapons or prohibited items being brought onto an aircraft.

Keeping the coats on during screening can block access to underneath and prevent thorough checks, while leaving them with luggage or packing them in the overhead compartment could lead to increased confusion and delays during the security process. Properly screening these outer garments as cabin baggage not only facilitates a smoother security flow but also aligns with the standard operating procedures within aviation security protocols.
