What You'll Learn
Security checks at entry and exit points
Passenger Screening:
Passenger screening is a crucial aspect of security checks at airports. This process involves multiple steps, including identity verification and carry-on baggage inspection. Passengers are required to present their identification documents, such as passports or driver's licenses, and their boarding passes during check-in. This pre-screening process also includes verifying visa and immigration status to ensure compliance with entry and exit requirements.
Baggage Screening:
Thorough baggage screening is essential to ensure that no prohibited items or potential threats are brought onboard aircraft or into the airport premises. Carry-on baggage is typically screened using X-ray machines, computer tomography (CT) scanners, and explosive detection systems (EDS). Passengers may be asked to remove personal electronic devices larger than cell phones, such as laptops and tablets, from their bags for separate screening. Checked baggage undergoes similar screening procedures, including X-ray inspections and, if necessary, physical searches.
Security Equipment and Technology:
Airport security relies on advanced technology to detect and prevent potential threats. Metal detectors, full-body scanners, and explosive detection devices are commonly used at security checkpoints. Closed-circuit television (CCTV) systems with facial recognition capabilities are also integral to airport security, allowing for the monitoring of suspicious behaviour and the identification of individuals. Additionally, some airports have implemented next-generation Enhanced Advanced Imaging Technology (eAIT) and touchless automated photo identification scanners to enhance security and improve the passenger experience.
Security Personnel:
Security checks at airports are conducted by trained personnel, including security guards, law enforcement officers, and, in some cases, members of organisations like the Transportation Security Administration (TSA) or the Canadian Air Transport Security Authority (CATSA). These individuals are responsible for overseeing the screening processes, conducting physical searches if needed, and addressing any suspicious activities. At smaller airports, firefighters may also take on security guard roles.
Pre-Arrival Security Measures:
Security measures often begin before passengers even arrive at the airport. Intelligence sharing between security organisations and law enforcement plays a vital role in identifying potential risks. Programs like Secure Flight pre-screen passengers by matching their names against trusted traveller lists and watchlists. Additionally, passengers and the general public are encouraged to report any suspicious activities, unattended bags, or individuals attempting to access restricted areas.
Security Checks for Domestic Flights:
While security checks have traditionally focused on international flights, there has been a growing recognition of the need for security on domestic flights as well. Many countries and airports have implemented mandatory security checks for passengers and luggage on all domestic flights, ensuring comprehensive safety measures regardless of the flight route.

Surveillance and monitoring
Closed-circuit television (CCTV) systems are also essential to airport security. These systems can track activities in any part of the airport, and modern commercially available models have autonomous facial recognition capabilities. Dedicated staff monitor these systems around the clock to ensure any questionable conduct is addressed promptly and to identify and flag individuals who may pose a security risk.
In addition to these measures, security checks and screenings are conducted by federal officials or private companies. These screenings may include identity verification, visa and immigration status checks, and the scanning of carry-on luggage and checked baggage. Hold baggage security screening (HBSS) employs X-ray, computer tomography (CT), and explosive detection systems (EDS) to check for prohibited items. Furthermore, security measures may be adjusted based on evolving threats to maintain the highest levels of transportation security.
Airport security often involves collaboration between different entities. For example, the Transportation Security Administration (TSA) in the United States works closely with international partners, law enforcement, and the intelligence community to share information and enhance security measures. Similarly, the Canadian Air Transport Security Authority (CATSA) implements security measures in conjunction with airport operators, and the French Vigipirate program uses troops to reinforce local security.
Overall, surveillance and monitoring play a critical role in airport security by utilising technology, human resources, and collaborative efforts to detect and prevent potential threats, ensuring the safety of passengers, staff, and property.

Screening of passengers and staff
Screening passengers and staff is a crucial aspect of airport security, aiming to prevent prohibited items and security threats from entering sterile areas. This process involves checking both individuals and their carry-on baggage. Security screening procedures typically include advanced technology and human inspections to ensure comprehensive safety measures.
Passenger screening plays a vital role in protecting passengers, staff, aircraft, and airport property from potential harm, terrorism, and other threats. Security personnel employ various methods, such as metal detectors, explosive trace detection (ETD) equipment, and X-ray machines to verify the contents of carry-on luggage. Additionally, passengers may undergo pat-down procedures, which involve inspecting their clothing and, if necessary, sensitive areas of the body to ensure no prohibited items are concealed.
The screening process also extends to electronic devices. Passengers are usually required to remove laptops, tablets, and other large electronic devices from their carry-on bags for separate X-ray screening. This measure ensures that these devices do not contain any prohibited items or modifications that could pose a security risk.
Some countries have implemented risk-based passenger pre-screening programs, such as Secure Flight in the United States. This program identifies low and high-risk passengers before they arrive at the airport by matching their names against trusted traveler lists and watchlists. It helps streamline the screening process, allowing low-risk passengers to expedite security with TSA PreCheck®.
Apart from passengers, airport staff are also subject to rigorous screening procedures. Security officers ensure that staff members have valid access authorizations, such as badges, before granting entry to restricted areas. This measure helps maintain security within the airport and prevents unauthorized access to sensitive areas.

Baggage and cargo checks
Checked Baggage Screening
Checked baggage is typically screened using advanced scanners, such as X-ray or CT machines, to examine the contents of each bag. These scanners can detect unusual shapes, densities, or materials that may pose a security risk. If something suspicious is detected, the bag may be flagged for further inspection, which could include a manual search. TSA-approved locks can be opened by security officers to inspect flagged bags without damaging them. If a bag has a lock that cannot be opened, it may be cut to ensure the contents are safe.
Carry-on Baggage Screening
Carry-on baggage is subject to screening procedures at security checkpoints within the airport. Passengers are required to remove personal electronic devices larger than a cell phone from their bags for separate X-ray screening. This includes laptops, tablets, e-readers, and handheld game consoles. Security personnel may also need to search carry-on bags for prohibited items or substances.
Baggage Handling and Security
Once checked baggage is screened and loaded onto the aircraft, it is the responsibility of baggage handlers or ramp agents to secure the cargo hold. They follow specific procedures to balance the aircraft and ensure the safety of the bags during the flight. After landing, the baggage handlers unload the luggage and send it through the airport's automated baggage handling system, which uses scanners to read tags and sort bags by their final destination.
Security Measures Beyond the Airport
Security measures related to air travel are not limited to the airport itself. For example, the Transportation Security Administration (TSA) works closely with intelligence and law enforcement agencies to gather information and maintain transportation security. Additionally, programs like Secure Flight pre-screen passengers before they arrive at the airport by matching names against trusted lists and watchlists. These measures demonstrate that baggage and cargo security is a comprehensive process that involves multiple agencies and extends beyond the physical boundaries of the airport.
