Airport security is a critical aspect of ensuring the safety of passengers, staff, and aircraft. It involves various techniques and procedures to safeguard civil aviation against unlawful interference, such as terrorism, sabotage, or threats to life and property. With a high volume of people passing through airports daily, effective security measures are essential to mitigate potential risks and threats. These measures include screening carry-on and checked baggage, implementing access control and video monitoring, and utilizing advanced technology like biometric scanning and fiber optic perimeter intrusion detection systems. Additionally, agencies like the Transportation Security Administration (TSA) in the US play a crucial role in maintaining aviation security standards and facilitating a smooth transition through security checkpoints.

What You'll Learn
Liquids, gels, and pastes
Firstly, you are allowed to bring a quart-sized bag of liquids, gels, and pastes in your carry-on luggage. This includes aerosols, creams, and similar substances. Each item should be in a container no larger than 3.4 ounces (100 milliliters). This facilitates the screening process and helps officers identify the items.
Secondly, for any liquids, gels, or pastes over 3.4 ounces, you should use your checked baggage. Even if you have a secure, tamper-evident bag, it is recommended that you place these items in your checked baggage. This helps to avoid any issues during the screening process, as any item that alarms during screening will require additional checks.
Medication and baby formula are two notable exceptions to the liquid rules. Medically necessary liquids, gels, and aerosols are permitted in reasonable quantities. This includes prescription medications and non-prescription liquid medications, which should be declared to security officers. Baby formula, including breast milk, is also allowed and does not require the child to be present. To expedite screening, it is suggested that these liquids be in clear or translucent bottles.
Finally, it is worth noting that powder-like substances over 12 ounces (350 milliliters) should be placed in checked baggage to avoid secondary screening. These rules are subject to change, so it is always advisable to check the latest guidelines before travelling.

Electronic devices
The Transportation Security Administration (TSA) is responsible for screening approximately 3.3 million carry-on bags for explosives and other dangerous items daily. Passengers are required to remove personal electronic devices larger than a cell phone, such as laptops, tablets, e-readers, and handheld game consoles, from their carry-on bags and place them in a bin for X-ray screening. It is important to note that these devices should be placed in the bin without anything on or under them.
For flights into the U.S., passengers may experience a more extensive screening process, including additional screening of personal electronic devices. It is recommended that passengers arrive early at the airport to allow sufficient time for this screening process.
To enhance security and facilitate the identification process, TSA has implemented optional facial recognition technology at certain checkpoints. Additionally, passengers with special needs or disabilities can avail assistance through the TSA Cares helpline, which provides support during the security screening process.
To expedite the security screening process, services like Clear Plus offer biometrics-based identification methods, allowing travelers to skip lengthy identification procedures and proceed directly to security checks. Clear Plus members can use their fingerprints, iris, or facial scans for identification, along with their boarding pass, at dedicated lanes.
It is important to note that airport security measures are crucial for ensuring passenger safety. These measures aim to prevent any threats or potentially dangerous situations, including unlawful interference, acts of terrorism, or the presence of illegal items. By adhering to these security protocols, airports strive to protect passengers, staff, aircraft, and property while also supporting national security and counter-terrorism policies.

Biometric scanning technology
The use of biometrics in airport security has been accelerated by the pandemic's preference for contactless experiences and the need to reduce touchpoints. Biometric scanners provide a more hygienic way to verify passenger identities, reducing the need for physical contact with documents or staff. Additionally, digital IDs stored on mobile devices are more secure than physical credentials, reducing the risk of counterfeiting or fraud.
TSA has been testing and evaluating biometric technologies at select airport checkpoints to automate the identification process. One example is the 1:1 facial matching capability, where a camera captures a passenger's photo and compares it to the image on their photo ID. Passengers can also scan their identity documents for authentication and biometric identity matching, further streamlining the process. These tests aim to enhance security while improving the overall passenger experience.
In 2021, San Francisco International Airport and United Airlines partnered to trial a low-touch, biometric-enabled airport journey for domestic travelers. Passengers used biometric facial scanners to check bags, pass through security, and board their flights without the need for physical documentation. This technology significantly reduced boarding times, enhancing efficiency and safety.
While the adoption of biometric technology in airports is growing, participation in biometric testing is currently voluntary. Passengers can choose to opt-out and undergo the standard ID verification process. TSA is committed to exploring and implementing these advancements while protecting privacy and civil liberties, working closely with various partners to ensure the security and accuracy of these systems.

Locks
The Transportation Security Administration (TSA) has rules on "prohibited items" that pose a security threat. These rules are separate from the FAA's dangerous goods safety rules. TSA's screening procedures are intended to prevent prohibited items and other threats to transportation security from entering the sterile area of the airport. TSA counts on the traveling public to report unattended bags or packages, individuals in possession of a threatening item, and persons trying to enter a restricted area or similar suspicious activities at airports.
TSA incorporates unpredictable security measures, both seen and unseen, to accomplish its transportation security mission. Security measures begin long before you arrive at the airport. TSA adjusts its processes and procedures to meet evolving threats and achieve the highest levels of transportation security. Because of this, you may notice changes in their procedures from time to time.
You may lock your luggage, but you must use a TSA-approved lock so that TSA screeners can open it if your bag is selected for inspection. If you don’t use a TSA-approved lock, TSA screeners will cut off the locks if they need to get into your bag. TSA-approved locks are commercially available, and the packaging on the locks should indicate that they may be opened by TSA officers. TSA has no position on the validity or effectiveness of these locks as a security measure and will be forced to remove them if necessary during the inspection.
