What is a common security measure for international flights?

Enhanced screening procedures for passengers and baggage is a critical security measure for international flights due to the increased risk factors and threats associated with international travel. These measures typically involve more thorough checks, including the use of advanced technology such as X-ray machines, body scanners, and chemical detection systems. Such procedures ensure that both carry-on and checked baggage are scrutinized for prohibited items or potential threats, which is particularly essential for international routes that may have different security requirements based on the countries involved.

By implementing enhanced screening, aviation authorities aim to prevent dangerous items from getting on board, thereby protecting passengers and crew alike from potential attacks or incidents. This is a fundamental aspect of ensuring safe air travel globally, reflecting the need for vigilance in an environment where security risks may vary significantly between countries.
