What You'll Learn

Liquids and creams: Containers must be 3.4 oz or less
Liquids, gels, creams, aerosols, and pastes fall under the Transportation Security Administration's (TSA) 3-1-1 rule. This means that travellers can take containers that hold up to 3.4 ounces (100ml) of liquid, gel, cream, aerosol, or paste as long as they are placed in a clear, quart-sized bag. Each passenger is allowed to carry one of these bags. The bag must be removed from carry-on luggage and placed in a bin for screening.
It is important to note that this rule applies to food items as well. For example, soup, sauces, and salad dressing are considered liquids and must adhere to the 3.4-ounce limit. However, frozen liquids, such as ice packs and frozen soups, are allowed as long as they are frozen solid during screening.
Additionally, there are some exceptions to the 3-1-1 rule. Medically necessary liquids, gels, and aerosols are allowed in reasonable quantities, but they must be declared to security officers first. Baby food and formula are also exempt from the rule and are permitted in reasonable amounts.
It is worth mentioning that even if an item is generally permitted, it may still be subject to additional screening or may not be allowed through the checkpoint if it triggers an alarm, appears tampered with, or raises security concerns. The final decision rests with the TSA officer regarding what items are allowed through the security checkpoint.

Frozen liquids: Allowed, but must be frozen solid
Frozen liquids are allowed through airport security as long as they are frozen solid when presented for screening. If the frozen liquid item is partially melted, slushy, or has any liquid at the bottom of the container, it must meet the 3-1-1 liquids requirement, which states that liquids and gels must be in containers that hold 3.4 ounces or less and be placed in a clear, quart-sized bag. Each passenger is allowed one quart-sized bag of liquids and gels.
It is important to note that the final decision on whether an item is allowed through the checkpoint rests with the TSA officer. Therefore, it is recommended to not pack any frozen liquid items that you would be upset to throw away. Additionally, food items with metal or in aluminum foil may trigger the metal detector and require additional screening.
Frozen liquids, such as ice, are generally allowed through airport security. However, there have been instances where TSA officials have confiscated items that may be considered ambiguous, such as a can of soda frozen in a block of ice, due to security concerns.
It is also worth noting that some travellers choose to bring empty bottles through security and fill them up at the water dispensers available in most airports. This avoids the hassle of freezing water bottles beforehand and ensures easy access to cold water during travel.

Solid foods: Most are allowed in carry-on bags
Solid foods are generally allowed in carry-on bags. This includes items such as sandwiches, wraps, bean burritos, fruit, bread, pizza, pies, cakes, chocolate, and other snacks. Liquids, gels, and creamy or spreadable items are subject to the 3-1-1 rule, which means they must be in containers of 3.4 ounces or less and placed in a clear, quart-sized bag. This includes items such as peanut butter, olive oil, salsa, jams, and other similar foods.
It is important to note that some solid foods may still be prohibited if they trigger the metal detector or raise security concerns. For example, food items in aluminum foil or containing metal may require additional screening. Additionally, certain types of food may be restricted depending on the country or region you are travelling to or from. For example, bringing meat or fresh produce into certain countries may be prohibited to prevent the spread of pests or diseases. It is always a good idea to check with the relevant authorities or the official TSA website for the most up-to-date and accurate information regarding what foods are allowed in carry-on bags.
To ensure a smooth airport security experience, it is recommended to pack solid foods in a separate bag from your other belongings. This will make it easier for security officers to screen your items and can help speed up the process. It is also important to declare any food items you are carrying, especially if they are unusual or potentially restricted. By following the guidelines and cooperating with security officers, you can bring a variety of solid foods with you on your travels.
Some travellers have shared their experiences of bringing solid foods through airport security. One person mentioned bringing a Subway sandwich, cut into quarters and placed in separate baggies, to make it easier for security screening. Another traveller mentioned bringing a full Chicago-style deep-dish pizza through security. While solid foods are generally allowed, it is always a good idea to be prepared for any additional screening or restrictions that may arise.

Fresh fruit and vegetables: Allowed on domestic flights
Fresh fruits and vegetables are allowed on domestic flights, but there are some important restrictions to keep in mind. Firstly, if you are flying from Hawaii, Puerto Rico, or the U.S. Virgin Islands to the U.S. mainland, you cannot take most fresh fruits and vegetables due to the risk of spreading invasive plant pests. This is a strict regulation, and failure to comply may result in penalties.
For travellers on domestic flights within the mainland, fresh fruits and vegetables are generally permitted in checked bags. It is also often acceptable to bring solid, fresh produce in carry-ons, provided they are not soft, mashed, or in a liquid state. In such cases, the Transportation Security Administration's (TSA) 3-1-1 rule for liquids would apply. This rule states that liquids and gels must be in containers of 3.4 ounces or less and placed in a clear, quart-sized bag for screening. Each passenger is allowed one such bag.
It is important to note that food items may be subject to additional screening or may not be allowed through the checkpoint if they trigger alarms, appear tampered with, or raise security concerns. To avoid issues, ensure that fresh fruits and vegetables are properly packaged and labelled, and comply with any requests from TSA officers during the screening process.
Additionally, some food items may trigger metal detectors and require additional screening. This includes items wrapped in aluminium foil or containing metal. To streamline your airport experience, consider packaging fresh fruits and vegetables separately from other food items and electronics. This will allow for easier inspection and reduce the likelihood of contamination or tampering.

Ice packs: Must be frozen solid, not slushy
The Transportation Security Administration (TSA) has strict guidelines for items that can be taken through airport security. While solid foods are generally allowed, liquids and gels must adhere to the 3-1-1 rule, which allows for containers holding 3.4 ounces or less of liquid or gel. Frozen liquid items are also allowed through checkpoints, but they must be completely frozen solid and not partially melted, slushy, or containing liquid at the bottom of the container. If they are not completely frozen, they must meet the 3-1-1 liquids requirements.
Ice packs are permitted by TSA guidelines, but they must remain completely frozen at the time of screening. Even a slight thaw can cause issues at the checkpoint. To maintain the frozen state of ice packs, travellers can use an insulated bag or a container specifically designed for this purpose. It is also a good idea to inform the TSA officers since they may inspect the contents of the bag or container.
Medically necessary gel ice packs are allowed regardless of their physical state, but travellers must notify the TSA officer at the checkpoint for inspection. It is important to note that TSA regulations and airline policies can change, so travellers should check for updates before each trip.
Travellers should also be aware that food items in aluminium foil or containing metal may trigger the metal detector and require additional screening. By following these guidelines, travellers can ensure a stress-free experience when bringing food and ice packs through airport security.
