Airports are busy places, and security is an essential part of the travel process. One of the most critical security measures is confirming the identity of travellers. This is done by checking photo identification, such as a driver's license or passport, and can also involve biometrics, including fingerprints, retinal scans, and facial pattern recognition. When travelling, it's essential to carry acceptable identification, as those without it may not be allowed to pass through security checkpoints. However, if you arrive at an airport without ID, you may still be able to fly if your identity can be confirmed through other means. Airports also have other security measures in place, such as screening luggage and asking security questions to travellers, to ensure the safety of passengers and staff.

What You'll Learn
Baggage check-in and security screening
Checked Baggage
Checked baggage is screened for prohibited items, hazardous materials, and potential threats to transportation security. Most hazardous materials are forbidden in checked baggage, with some exceptions for personal care items like toiletries, medicines, battery-powered devices, and assistive devices. Religious items like knives or swords must also be packed in checked baggage. Any powder-like substances over 12 oz or 350 ml should be placed in checked baggage, as they may require additional screening at the central checkpoint and may not be allowed in the aircraft cabin. Food is allowed in checked baggage but must undergo x-ray screening.
Carry-on Baggage
Carry-on baggage is screened for explosives and other dangerous items. TSA agents screen approximately 3.3-4.9 million carry-on bags daily. Liquids, gels, and aerosols are allowed in carry-on baggage but must follow the 3-1-1 rule, with containers no larger than 3.4 oz or 100 ml. Food is allowed in carry-on baggage but must comply with the same 3-1-1 rule for liquids. Electronic devices with lithium-ion batteries, such as battery chargers and portable batteries, are only allowed in carry-on baggage.
Personal Screening
Passengers are also screened to ensure they are not carrying prohibited items or threats to transportation security. This includes the use of metal detectors and body scanners. Passengers with certain items or clothing, such as hair extensions, braids, or bulky clothing, may be subject to additional screening or pat-downs. Pat-downs are conducted by a same-gender TSA officer and are used to resolve any concerns identified during the screening process.
Identification
Passengers are required to provide acceptable identification during the security screening process. In rare cases, if a passenger arrives without acceptable identification, the TSA has alternative methods to confirm their identity, such as through additional information provided by the passenger.

Pat-downs and searches
Pat-down searches are an additional security measure that may be undertaken as part of airport security screening routines. If a passenger sets off a metal detector or is chosen for extra screening, they may be subjected to a pat-down search. It is important to note that the Federal Aviation Administration (FAA) does not allow race, national origin, religion, gender, ethnicity, or political beliefs to be used when selecting who undergoes further screening.
During a pat-down search, a Transportation Security Officer (TSO) will use their hands to feel for items that may be hidden on an individual's body or underneath their clothes. The TSO is required to use the back of their hand to search sensitive areas of the body, such as the crotch or upper chest. A TSO may check the outside perimeter of a female passenger's chest, including above and under the breasts, and between the breasts if they have set off a hand-held metal detector in that area. Passengers have the right to request that the pat-down be conducted by a person of their gender and that it occurs in a private area. If a passenger declines the pat-down, they may be subject to further scrutiny or even ejected from the airport.
In addition to pat-downs, TSA officers may also perform bag searches. Passengers are required to empty their pockets, remove jackets, and go through a body scanner. If a passenger is carrying powders in their carry-on baggage, they may be required to undergo secondary screening, and powders that cannot be identified by security officials will be prohibited from the cabin of the aircraft. Electronics are currently not restricted for carry-on baggage, but most hazardous materials are forbidden in both carry-on and checked baggage.

Boarding pass scanning
The boarding pass scanning process at airports has evolved in recent years, with new technologies being introduced to enhance security and streamline the travel experience. One significant advancement is the implementation of Credential Authentication Technology (CAT) scanners. These machines allow TSA officers to verify a traveller's identity and flight details without the need for a physical boarding pass. By scanning an official ID, such as a driver's license, passport, or Trusted Traveller ID, the system matches the passenger's biographical information with the flight manifest in real time. This technology is now available at over 225 airports across the United States, including major hubs like Atlanta's Hartsfield-Jackson International Airport, Los Angeles International Airport, and New York's John F. Kennedy International Airport.
The introduction of CAT scanners has brought several benefits. Firstly, it eliminates the need for travellers to scramble for their boarding passes at security checkpoints, reducing the time spent in security lines. Secondly, it improves security by enabling the TSA to confirm travellers' identities and flight details instantly. Additionally, CAT scanners support the use of digital IDs, such as the Apple Wallet app, where passengers can upload their state-issued IDs and breeze through checkpoints using their iPhones or Apple Watches.
While CAT scanners have revolutionised the security process, traditional boarding pass scanning is still prevalent at many airports. During the boarding pass scanning process, security personnel verify the passenger's information, including their name, flight number, and seat assignment. This process is now often complemented by additional security measures, such as facial recognition technology. For example, at Manchester Airport in the UK, passengers are photographed during check-in, and this image is compared with the one captured at the gate to ensure they are boarding the correct flight.
Furthermore, the use of QR codes for boarding passes has gained traction in recent years. Many airlines, including Delta Air Lines and Lufthansa, have adopted this technology to enhance passenger convenience. QR codes can be easily scanned from a passenger's mobile device, eliminating the need for paper boarding passes. This not only speeds up the check-in process but also reduces paper waste. Additionally, QR codes can be used for in-flight purchases and accessing tourist information, further improving the overall travel experience.
Overall, the evolution of boarding pass scanning, from traditional paper passes to CAT scanners and QR codes, reflects the aviation industry's commitment to enhancing security, expediting travel, and improving passenger convenience. These advancements contribute to a more seamless and efficient airport experience, ensuring travellers can reach their destinations safely and promptly.

ID checks at the boarding gate
The purpose of ID checks is to verify a passenger's identity and ensure that the person holding the boarding pass is the person authorised to board the flight. This is particularly important for international flights and, in most parts of the world, airlines adhere to a policy called Positive Passenger Bag Match (PPBM), which requires that all bags flying must be matched to a passenger on board. This means that if you have checked in bags, the airline knows you are in the airport, and your bags cannot be loaded onto the plane if you are not on the flight.
TSA officers, who are not usually commissioned law enforcement officers, conduct security screenings at airports. They can search passengers and their baggage at screening checkpoints but cannot arrest anyone. Other law enforcement officers, such as airport police, are also present at airports and may be involved in ID checks. While TSA officers can request additional screening, they are not permitted to select passengers for a personal search or secondary inspection based on religion, race, national origin, gender, ethnicity, or political beliefs.

Behavioural cues
Maintaining a calm and composed demeanour is essential when going through airport security. Losing one's temper, exhibiting anger, or displaying belligerent behaviour can attract unwanted attention from security officers. Such behaviour may indicate underlying issues, and security personnel are trained to identify these behavioural cues and respond accordingly. It is crucial to remember that security officers are there to ensure the safety of all passengers and that unexpected delays or cancellations can be frustrating for everyone.
The way a person dresses can also be a factor in behavioural cues at airport security. Baggy or bulky clothing may prompt additional screening as it can be challenging for officers to determine what an individual might be hiding underneath. Passengers wearing such clothing may be asked to remove these items or undergo a pat-down search to ensure they are not concealing any prohibited items. It is recommended to wear clothing that conforms to the body's contour to streamline the security process.
Additionally, certain actions or mannerisms can stand out to security officers. For instance, passengers who appear nervous or anxious may draw attention. While it is natural to experience some level of anxiety when travelling, excessive nervousness or fidgeting may prompt further scrutiny. Security officers are trained to identify these subtle behavioural cues and may engage in conversation or ask additional questions to assess the situation.
Another behavioural cue that security officers look out for is how passengers interact with their luggage. Unusual behaviour, such as a reluctance to let go of one's luggage or an attempt to rush through security without proper screening, can be a red flag. Officers are trained to observe passenger interactions with their belongings and may request additional screening or ask questions to clarify any concerns. It is important to remain cooperative and follow the instructions provided by security personnel to ensure a smooth process.
