Bringing your own lunch through airport security can save you money and be more convenient than buying food at the airport. The short answer is that you can bring food through security, but there are some important exceptions and rules to know. The Transportation Security Administration (TSA) has a 3-1-1 rule for liquids, which means you can carry up to 3.4 ounces of liquids, gels, creams, and pastes in a one-quart bag. This rule applies to food items with a high liquid concentration, like peanut butter, hummus, and yogurt. Solid food items are allowed in carry-on or checked baggage, but liquid and gel snacks are only allowed in carry-ons if they follow the 3-1-1 rule. Baby food, breast milk, and formula are exempt from these rules and can be brought in reasonable quantities. It's important to note that even if a food item is generally permitted, it may be subject to additional screening or not allowed through security if it triggers an alarm, appears tampered with, or poses security concerns.

What You'll Learn

Liquids, gels, creams, pastes and the 3-1-1 rule
Liquids, gels, creams, and pastes are subject to the 3-1-1 rule when passing through airport security. This rule allows travellers to bring a quart-sized bag of liquids, gels, creams, and pastes in their carry-on luggage. Each container must be 3.4 ounces (100ml) or smaller in volume. The purpose of the rule is to enhance aviation security while allowing travellers to carry essential items.
The rule applies to toiletries, medication, beverages, and food items with a liquid or gel consistency. For example, peanut butter, yoghurt, and hot chocolate mix are subject to the 3-1-1 rule. Other liquid or creamy snack items that are not allowed in carry-on luggage include full-sized containers of creamy dips, spreads, and cheeses, salad dressings, oils, vinegars, salsas, and other sauces.
There are some exceptions to the 3-1-1 rule. For instance, baby formula, breast milk, and medication exceeding the limit may be permitted but require separate screening. Duty-free liquids purchased internationally and packed in a transparent, secure, tamper-evident bag by the retailer may also be allowed in carry-on luggage.
To ensure a smooth security process, travellers are advised to prepare their quart-sized bag before arriving at the security checkpoint and to use travel-sized containers. Understanding the specifics of the 3-1-1 rule can help alleviate travel stress.

Solid, dry foods
It is important to note that solid foods should be properly sealed in a leak-proof container or their original packaging. This is because food items that appear to have been tampered with may be subject to additional screening or may not be allowed through the checkpoint.
Foods that are dry and have a long shelf life are also a good option, such as crackers, dried fruits, nuts, and cereal. These items are less likely to be affected by changes in temperature or time and can be stored for longer periods without spoiling.
Additionally, it is worth noting that while most solid, dry foods are allowed, some items with a high liquid content may be subject to scrutiny. For example, peanut butter, hummus, and jelly/jam are considered liquids and are limited to containers of 3.4 ounces or 100 milliliters. This also applies to alcoholic beverages, which must be less than 3.4 ounces and less than 70% alcohol by volume (140 proof).
Overall, when packing solid, dry foods for air travel, it is best to opt for items that are sealed, have a long shelf life, and do not contain high amounts of liquid to ensure a smooth passage through airport security.

Alcoholic drinks
It is important to note that you are not allowed to drink alcohol on board unless it is served by a flight attendant. This means that any mini bottles of liquor must be stowed in your carry-on luggage for the duration of the flight.
Even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm, appears tampered with, or poses security concerns. The final decision rests with the TSA officer at the checkpoint.

Frozen food
To ensure your frozen food stays frozen, you can use gel packs or dry ice. If using dry ice, notify the airline that you are doing so, and they will label it appropriately. Be aware that there are state agricultural restrictions for certain food products, and there may be restrictions when travelling between countries.
The Transportation Security Administration (TSA) states that food is allowed through security, as long as it meets other checkpoint requirements. Liquid foods and gel snacks are subject to the 3-1-1 rule, meaning they are allowed in carry-on bags only if they are in containers of 3.4 ounces or less and fit in a quart-sized bag. Alcohol is also subject to quantity restrictions, with alcohol over 70% volume or 140 proof not being allowed through security.
Even if your frozen food meets all the requirements, it may be subject to additional screening or not be allowed through the checkpoint if it triggers an alarm, appears tampered with, or poses security concerns. The final decision rests with the TSA officer.

Baby food
Baby formula, breast milk, toddler drinks, and baby/toddler food (including puree pouches) are considered medically necessary liquids by the TSA. This means that you can bring baby food in reasonable quantities in your carry-on baggage and you are not restricted by the 3.4-ounce rule that applies to other liquids.
However, it is important to remove these items from your carry-on bag so they can be screened separately from the rest of your belongings. You should also inform the TSA officer at the beginning of the screening process that you are carrying these items. Although not required, it is ideal to keep formula and breast milk in their original packaging or clear, translucent bottles.
Accessories required to cool baby food, such as ice packs, freezer packs, and gel packs, are also allowed in carry-ons, regardless of the presence of breast milk.
There is no legal limit to how much baby food you can bring, but it is always good to check with your airport before you travel.
