If you're planning to bring a poboy sandwich to the airport, it's important to be aware of the security measures and restrictions in place. Airport security screenings are conducted by the Transportation Security Administration (TSA) to prevent prohibited items and other threats to transportation security. While food items like poboy sandwiches are generally allowed, they may be subject to additional screening if they trigger an alarm, appear tampered with, or pose security concerns. It's also important to note that you must show valid identification at the airport checkpoint and that certain items, such as liquids, powders, electronics, and hazardous materials, have specific restrictions. Customs officers may also ask about your immigration status and search your belongings, including electronic devices, when entering a country. Planning ahead and packing properly can help facilitate the screening process and ensure a smooth travel experience.

Food allowance: Liquids, powders, gels and aerosols have quantity restrictions
Passengers are allowed to bring food items to the airport, but there are restrictions on the quantity of liquids, powders, gels, and aerosols that can be carried in hand luggage. These restrictions are in place to ensure the safety and security of passengers and staff. Powders, in particular, may require additional screening, and any substance that cannot be resolved by security officials will not be permitted on the aircraft.
For international flights, the volume of liquids, gels, and aerosols carried by each passenger is restricted. Individual containers must not exceed 100ml or 3.4 ounces, and all containers must fit into a single resealable, transparent plastic bag with a volume of one litre. This restriction applies to the container size, not the amount of liquid inside. Any liquid, gel, or aerosol that exceeds 100ml will not be permitted, even if the container is only partially full. Passengers travelling with young children can carry more food, drink, baby powder, and formula than the restricted limits, but only in amounts deemed reasonable for the flight.
Inorganic powders, such as salt, talcum powder, sand, and cremated remains, are limited to 350ml or 350 grams per person. This is roughly the size of a standard can of soda. Passengers must declare these items at the screening point, but they do not need to be placed in a clear plastic bag. Organic powders, such as food and baby formula, are not subject to volume limits, but they must also be declared during screening.
Passengers can bring duty-free liquids, gels, and aerosols in secure, tamper-evident bags if purchased internationally and travelling to the US with a connecting flight. The bags must be transparent and show no signs of tampering. These items must still undergo screening and clearance, and any item that alarms during screening will not be permitted. For domestic flights within Australia, there are no restrictions on liquids, powders, gels, and aerosols, but all aerosol containers must have a fitted cap or locking device and be presented during screening.
It is important to note that these restrictions are subject to change, and passengers should always check with their airline and local airport for the most up-to-date information. Additionally, passengers have the right to wear religious head coverings during security screening, but additional screening may be required if an alarm is triggered.

Electronic devices: Devices must be powered and may be subject to additional screening
When going through airport security, you will be asked to remove personal electronic devices larger than a cell phone from your carry-on bag and place them into a bin for X-ray screening. This includes items such as laptops, tablets, e-readers, and handheld game consoles. Make sure your devices are powered, as powerless devices will not be permitted onboard the aircraft. You may be asked to power up your device by a TSA officer.
TSA officers may instruct you to separate other items from your carry-on bag, such as food, powders, and any materials that can clutter bags and obstruct clear images on the X-ray machine. Powders over 12 oz. / 350 mL must be placed in checked bags, and those in carry-on baggage may require secondary screening.
TSA officers may also ask you to undergo a pat-down, which will be conducted by an officer of the same sex. They will explain the procedure to you as they conduct the pat-down. You may request a chair if needed and can also request private screening accompanied by a companion of your choice.
At the border, you may encounter Customs and Border Protection (CBP) officers and Homeland Security Investigations (HSI) agents. Customs officers have the authority to search your belongings for contraband, including electronic devices such as laptops and cell phones, though this is a contested legal issue. They may also ask about your immigration status to determine whether you have the right to enter the country.

Identity checks: Passengers 18+ must show valid ID. Non-compliant IDs require alternatives
When travelling, it is important to plan ahead and pack properly to facilitate the screening process and ease your travel experience at the airport. Passengers aged 18 and above are required to show valid identification at the airport checkpoint to be able to travel. The list of acceptable IDs may change without notice, so it is recommended to check the list before travelling.
TSA-accepted valid IDs include:
- REAL ID-compliant driver's licenses
- State photo identity cards issued by the Department of Motor Vehicles (or equivalent)
- Temporary driver's licenses are not accepted
- State-issued Enhanced Driver's License (EDL) or Enhanced ID (EID)
- U.S. passport or passport card
- DHS trusted traveler cards (Global Entry, NEXUS, SENTRI, FAST)
- U.S. Department of Defense ID, including IDs issued to dependents
- Federally recognised Tribal Nation/Indian Tribe-issued photo ID, including Enhanced Tribal Cards (ETC)
If a passenger presents a state-issued ID that is not REAL ID-compliant, they will be notified of their non-compliance and may be directed to a separate area for additional screening. This includes TSA PreCheck passengers. The TSA officer may ask for additional information, such as the passenger's name and current address, to confirm their identity. Passengers who do not cooperate with the identity verification process or whose identity cannot be confirmed will not be allowed to enter the security checkpoint.
Passengers have the right to wear religious head coverings during security screenings. However, if an alarm is triggered, officers may request additional screening, such as a pat-down of the head covering or asking the passenger to remove it. Passengers can request that the pat-down or removal be conducted by a person of their same gender in a private area. If a passenger does not want the officer to touch their head covering, they must inform the officer and request to pat down their own head covering under supervision.
It is important to note that customs officers may ask about immigration status to determine admissibility to a country, and they may search belongings and electronic devices for contraband. However, officers cannot select individuals for a personal search or secondary inspection based on religion, race, national origin, gender, ethnicity, or political beliefs.

Baggage screening: All carry-on bags are screened for explosives and dangerous items
Airport security screening is an extensive process that involves the screening of carry-on and checked baggage for explosives and other dangerous items. The Transportation Security Administration (TSA) is responsible for conducting these security screenings at airports. Here is what you need to know about baggage screening:
Screening Procedures
TSA officers screen approximately 3.3 million carry-on bags daily for explosives and other prohibited items. During the screening process, you will be asked to remove personal electronic devices larger than a cell phone, such as laptops, tablets, e-readers, and handheld game consoles, from your carry-on bag. These devices undergo separate X-ray screening in a bin with nothing placed on or under them. It is important to keep your bag organized to facilitate the screening process. TSA officers may also instruct you to separate food, powders, and other items that can clutter the bag and obstruct clear X-ray images.
Hazardous Materials and Prohibited Items
Most hazardous materials are forbidden in both carry-on and checked baggage. This includes items that pose a security threat, such as explosive materials, weapons, and other dangerous articles. Powders in carry-on baggage may require secondary screening, and powders that cannot be resolved will be prohibited in the aircraft cabin. It is recommended to place powder-like substances over 12 oz. / 350 mL in your checked bags. Additionally, TSA officers may ask you to power up your electronic devices, including cell phones, and powerless devices will not be permitted onboard.
Additional Screening
Even if an item is generally permitted, it may be subject to additional screening if it triggers an alarm during the initial screening, appears tampered with, or raises security concerns. TSA officers have the authority to conduct further searches of your person or baggage if necessary. This can include a pat-down or removal of religious headwear, with the right to request a private screening by a person of your same gender. Customs and Border Protection (CBP) officers may also conduct searches and ask about your immigration status to determine your admissibility into the country.
Planning and Preparation
To ease your travel experience, it is recommended to plan ahead and pack properly. Allow enough time for the screening process by arriving at the airport early. You can refer to the TSA's travel tips for packing and screening advice. Additionally, stay vigilant and report any unattended bags, suspicious individuals, or potential security threats to local law enforcement.

Personal searches: TSA officers can search you and your baggage but not arrest you
While there is no information on whether you can bring a Po'boy sandwich to the airport, here is some information on personal searches at the airport.
TSA officers are authorised to conduct security screenings of passengers, baggage, and cargo at airports. They may search you and your baggage at screening checkpoints, but they are not commissioned law enforcement officers and cannot arrest you. TSA screenings are intended to prevent prohibited items and other threats to transportation security from entering the airport's sterile area. Even if the initial screening of your bags reveals nothing suspicious, TSA officers have the authority to conduct a further search of you or your bags.
If you are wearing a religious head covering, you should assert your right to wear it through the screening process. However, if an alarm goes off, TSA officers may request additional screening, which may include a pat-down of your religious head covering or asking you to remove it. You have the right to request that the pat-down or removal be conducted by a person of your gender in a private area. If you do not want the TSA officer to touch your religious head covering, you must inform them and state that you would prefer to pat down your own head covering under supervision. After the pat-down, the TSA officer may rub your hands with a small cotton cloth to test for chemical residue.
TSA officers may not select you for a personal search or secondary inspection based on your religion, race, national origin, gender, ethnicity, or political beliefs. This also applies to law enforcement officers at the airport and the border, who generally have the authority to search all bags and ask questions about your citizenship and travel itinerary. Customs officers may stop people at the border to determine their admissibility to the country and search their belongings for contraband. They may also ask about your immigration status and question your immigration documents, such as visas.
If you believe your rights have been violated, you should contact an attorney for legal advice and assistance.
