The Transportation Security Administration (TSA) plays a critical role in maintaining the security of the United States' transportation systems, with a primary focus on aviation. TSA guidelines in 2024 have evolved to address emerging threats and enhance the efficiency of security procedures. These guidelines encompass a wide range of policies and procedures aimed at safeguarding passengers, crew, and airport staff while ensuring a smooth travel experience. This comprehensive overview of the TSA guidelines in 2024 highlights key aspects such as passenger screening, carry-on regulations, prohibited items, special considerations, and technological advancements.

Passenger Screening Procedures

Standard Screening

The standard screening process remains the backbone of TSA's security measures. Passengers undergo screening at security checkpoints, where they pass through metal detectors or advanced imaging technology (AIT) scanners. AIT scanners use millimeter wave technology to detect both metallic and non-metallic threats, providing a more thorough and less intrusive screening method.

Passengers are required to place their carry-on items, including electronics larger than a cell phone, liquids, and personal items, in bins for X-ray screening. Shoes, belts, and light jackets must also be removed and placed in bins. The TSA continues to emphasize the 3-1-1 liquids rule, which allows passengers to carry liquids, aerosols, gels, creams, and pastes in containers of 3.4 ounces (100 milliliters) or less, all placed in a single quart-sized, clear, resealable plastic bag.

TSA PreCheck

TSA PreCheck, a trusted traveler program, offers expedited screening for pre-approved, low-risk passengers. In 2024, TSA PreCheck members continue to enjoy the benefits of not having to remove shoes, belts, or light jackets, and being able to keep laptops and compliant liquids in their carry-on bags. The TSA has expanded the program, making it available at more airports and with more participating airlines.

To maintain eligibility for TSA PreCheck, members must undergo periodic background checks and renew their membership every five years. The TSA also conducts random screening of TSA PreCheck passengers to ensure the integrity of the program.

Carry-On Regulations

Liquids, Gels, and Aerosols

The 3-1-1 liquids rule remains a fundamental aspect of TSA's carry-on regulations. Each passenger is allowed to bring one quart-sized bag of liquids, gels, and aerosols, with each container holding no more than 3.4 ounces (100 milliliters). Exceptions are made for medications, baby formula, and breast milk, which are allowed in reasonable quantities exceeding 3.4 ounces but must be declared and screened separately.

Electronics

Electronics larger than a cell phone, such as laptops, tablets, and e-readers, must be removed from carry-on bags and placed in bins for X-ray screening. The TSA's efforts to streamline this process include new guidelines for TSA PreCheck members, allowing them to keep their electronics in their bags during screening. Additionally, the TSA has introduced "smart lanes" at select airports, equipped with automated bins that return to the start of the conveyor belt, enhancing the efficiency of the screening process.

Prohibited Items

The TSA maintains a comprehensive list of prohibited items that are not allowed in carry-on or checked baggage. This list includes, but is not limited to, firearms, explosives, flammable items, sharp objects, and certain tools. In 2024, the TSA has enhanced its communication and education efforts to ensure passengers are aware of these restrictions before arriving at the airport. This includes updated signage, mobile app alerts, and online resources.

Prohibited Items

The TSA maintains strict regulations regarding prohibited items to ensure the safety of all passengers and crew. In 2024, the list of prohibited items includes:

• Firearms and Ammunition: Firearms, including handguns, rifles, and shotguns, are prohibited in carry-on baggage. They can be transported in checked baggage, provided they are unloaded, packed in a hard-sided, locked container, and declared to the airline. Ammunition is also restricted and must be appropriately packed in checked baggage.
• Explosives and Flammable Materials: Explosives, fireworks, flares, and flammable materials such as gasoline, lighter fluid, and aerosol cans (except for small personal care items) are prohibited in both carry-on and checked baggage.
• Sharp Objects: Items such as knives, scissors with blades longer than 4 inches, box cutters, and razor blades are not allowed in carry-on baggage. They may be packed in checked baggage if properly secured.
• Tools: Tools longer than 7 inches, such as hammers, drills, and saws, are prohibited in carry-on baggage. Smaller tools, such as screwdrivers and wrenches, are allowed but must adhere to size restrictions.
• Self-Defense Items: Self-defense items like pepper spray, stun guns, and martial arts weapons are prohibited in carry-on baggage. Some items may be allowed in checked baggage with proper packaging and airline approval.

Special Considerations

Medical Conditions and Disabilities

Passengers with medical conditions or disabilities are entitled to special accommodations during the screening process. In 2024, the TSA continues to prioritize the needs of these passengers, ensuring that the screening process is respectful and accommodating. Travelers with medical conditions or disabilities are encouraged to inform the TSA officer at the security checkpoint and may request alternative screening methods if necessary.

Medical devices, such as insulin pumps, pacemakers, and oxygen concentrators, are allowed through security but must undergo additional screening. Passengers can carry medically necessary liquids, gels, and aerosols in quantities exceeding the 3-1-1 rule, provided they declare these items at the checkpoint and allow for separate screening.

Traveling with Children

Families traveling with children face unique challenges at airport security checkpoints. In 2024, the TSA continues to offer family-friendly screening options to make the process easier. Children under 12 years old can keep their shoes, light jackets, and headwear on during screening. Additionally, families traveling with children can use dedicated family lanes at select airports to expedite the screening process.

Parents and guardians are allowed to carry formula, breast milk, and baby food in reasonable quantities exceeding the 3-1-1 rule. These items must be declared at the checkpoint and undergo separate screening. Strollers, car seats, and other child-related equipment must also be screened, but the TSA strives to make this process as smooth as possible.

Technological Advancements

Biometrics and Facial Recognition

In 2024, the TSA made significant strides in incorporating biometric technology into the security screening process. Biometrics, such as facial recognition, are used to verify passengers' identities and streamline the screening process. Passengers enrolled in TSA PreCheck or Global Entry can opt to use facial recognition technology at participating airports, reducing the need for physical travel documents and enhancing security.

The use of biometrics has raised privacy concerns, and the TSA has implemented strict data protection measures to address these issues. Biometric data is securely stored and used solely for security purposes, with robust protocols in place to prevent unauthorized access.

Advanced Imaging Technology

Advanced Imaging Technology (AIT) scanners have become a standard feature at airport security checkpoints. These scanners use millimeter wave technology to detect threats, providing a more comprehensive and less intrusive screening method than traditional metal detectors. In 2024, the TSA will continue to upgrade and expand the use of AIT scanners, improving their accuracy and efficiency.

AIT scanners create a generic outline of the passenger's body, highlighting areas that require further inspection. This technology ensures that all passengers, regardless of body type or attire, receive a consistent and thorough screening. The TSA has also enhanced training for officers to ensure the effective and respectful use of AIT scanners.

Enhancing Efficiency and Passenger Experience
