Airport security can be a stressful experience, especially when it comes to knowing what food and drink you can take through. The Transportation Security Administration (TSA) has strict guidelines in place to ensure the safety of passengers and their belongings. While solid foods such as sandwiches, fruit, and snacks are allowed, liquids and gels are prohibited and must follow the 3-1-1 rule, meaning containers must hold 3.4 ounces or less and fit in a clear, quart-sized bag. This includes alcoholic drinks, although there are exceptions for baby food and drinks. Food items may also trigger additional screening if they contain metal or appear tampered with. Ultimately, the final decision rests with the TSA officer, who ensures items comply with regulations.

What You'll Learn

Solid foods are allowed through security
Solid foods are allowed through airport security. This includes sandwiches, fruit, snacks, protein bars, chips, pizza, pies, cakes, hard cheese, frozen seafood, fresh eggs, and more. However, it's important to note that solid foods must go through an X-ray machine for screening and may be subject to additional checks if they trigger the metal detector or raise security concerns. For example, food wrapped in aluminum foil or containing metal may require further screening.
While solid foods are generally permitted, it's always a good idea to check the specific regulations of your departure and destination countries, as these can vary. Additionally, it's worth noting that while most solid foods are allowed, some foods with a high liquid content may be considered liquids by the TSA and fall under their 3-1-1 rule for liquids and gels. 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.
To ensure a smooth travel experience, it's recommended to plan ahead and package your food items securely and in accordance with the guidelines.

Liquids and gels must follow the 3-1-1 rule
The 3-1-1 rule applies to foods that fall under the liquids, gels, or spreadable category. This includes items such as drinks, soups, sauces, peanut butter, olive oil, salsa, and yoghurt. For example, a jar of peanut butter that is larger than 3.4 ounces or 100ml will not be allowed through security. However, if you have small bottles of 3.4 ounces or less and they fit in your single one-quart bag, you can take them through security with you.
The 3-1-1 rule does not apply to ice because it is a solid. So, you can fill your reusable water bottle with ice before leaving home.
There are some exceptions to the 3-1-1 rule for liquids and gels. The TSA allows small bottles of alcohol as long as they comply with the 3-1-1 rule. However, the FAA does not permit passengers to consume these bottles in-flight. You can take them to your destination, but you cannot drink them on the plane.
There are also special guidelines for parents travelling with baby food, baby formula, and juices in carry-on bags. These items are fine in checked luggage, but if you want to bring them on the plane, they will need a special screening. Water for babies (in reasonable quantities) is also allowed in carry-on baggage.

Alcohol over 70% is prohibited
When it comes to food and drink, the Transportation Security Administration (TSA) has stringent rules for liquids. Solid foods, such as sandwiches, fruit, and snacks, can go through airport security. However, they must go through the X-ray machine for screening. Food items in aluminum foil or containing metal may trigger the metal detector and require additional screening.
Liquids and gels are on the prohibited items list and cannot go through airport security. This includes drinks, soups, and sauces. However, there is an exception to this rule. The TSA's 3-1-1 rule allows containers holding 3.4 ounces or 100ml or less of liquid or gel. Each passenger can have one quart-sized bag of liquids and gels. These containers must be placed in a clear, quart-sized bag and taken out of carry-on luggage to be placed in a bin for screening.
Alcoholic beverages are subject to similar restrictions. Alcohol over 70% ABV or 140 proof is prohibited on planes. This includes grain alcohol and 151 proof rum. Alcoholic beverages containing more than 24% but not more than 70% ABV (up to 140 proof) are allowed in unopened retail packaging. The quantity is limited to 5 liters per packaging and a total of 5 liters per passenger. These beverages must be in unopened packaging and comply with the 3-1-1 rule for liquids. Passengers are prohibited from drinking alcohol onboard unless served by the air carrier.
It is important to note that even if an item is generally permitted, it may be subject to additional screening or prohibited if it triggers an alarm, appears tampered with, or poses security concerns. The final decision rests with the TSA officer regarding items allowed through the checkpoint.

Baby food and water are allowed in carry-on baggage
If you are travelling with a baby, you may bring baby food and water in your carry-on baggage. Baby food is allowed in reasonable quantities in carry-on bags. This includes formula, breast milk, toddler drinks and baby/toddler food (including puree pouches). These items are considered medically necessary liquids and are exempt from the standard liquid restrictions. You can also bring ice packs, freezer packs, frozen gel packs and other accessories to cool these items.
It is important to note that these items should be removed from your carry-on bag and screened separately from the rest of your belongings. You should inform the TSA officer at the beginning of the screening process that you are carrying these items. Even if generally permitted, items may be subject to additional screening or not allowed through the checkpoint if they trigger an alarm during the screening process, appear tampered with, or pose security concerns.
Water for babies in reasonable quantities is also allowed in carry-on baggage. This is an exception to the standard liquid restrictions, which typically limit passengers to containers of 3.4 ounces (100 milliliters) or less. However, this rule does not apply to ice, as it is considered a solid, so you can fill your water bottle with ice before leaving home.
While bringing food and water for babies on board is permitted, other liquids and gels must comply with the 3-1-1 rule. This means that containers must hold 3.4 ounces (100 milliliters) or less of liquid or gel and must fit comfortably in a clear, quart-sized bag. Each passenger is allowed one quart-sized bag of liquids and gels.
