Can You Bring Food on a Plane? Rules by Type

Yes, you can bring food on a plane — but the rules depend on whether the food is solid or liquid. Solid foods pass through security freely. Foods that are liquid, gel, or spreadable fall under the liquids rule and are limited to 100ml containers in carry-on. Here is a clear breakdown by food type.

The Core Rule: Solid vs. Liquid

Airport security applies the liquids rule (also called the 3-1-1 rule in the US) to anything that is a liquid, gel, cream, paste, or aerosol. This applies to food just as much as it applies to shampoo and toothpaste.

Solid food = no restriction in carry-on. If you can pick it up without it flowing or spreading, it is generally treated as a solid.

Liquid or gel food = 100ml limit per container in carry-on. All containers must fit in a single clear plastic quart-sized bag (US) or equivalent. Items that do not fit must go in checked baggage or be discarded at the checkpoint.

Foods That Are Always Fine in Carry-On

These are solid foods with no restrictions:

• Sandwiches and wraps
• Fresh fruit and vegetables (whole pieces — see customs rules below)
• Granola bars, protein bars, energy bars
• Chips, crackers, and dry snacks
• Nuts and trail mix
• Cookies and baked goods
• Cheese (hard cheese — soft spreadable cheese is a gel)
• Bread and bagels
• Cooked meat (not in liquid or sauce)
• Candy and chocolate
• Dried fruit

You can bring as much solid food as fits in your carry-on bag. There are no quantity restrictions on solids at security.

Foods Subject to the 100ml Liquids Rule

These foods count as liquids or gels and must follow the 100ml rule in carry-on:

• Peanut butter and nut butters — spreadable, counts as gel; 100ml or less in carry-on
• Yogurt — counts as liquid; 100ml or less
• Hummus and dips — counts as gel; 100ml or less
• Guacamole and salsa — counts as gel; 100ml or less
• Jam and jelly — counts as gel; 100ml or less
• Soup and broth — liquid; 100ml or less
• Juice and smoothies — liquid; 100ml or less (unless purchased after security)
• Soft cheeses (Brie, ricotta, cream cheese) — gel consistency; 100ml or less
• Ice cream — if melted or soft, counts as liquid; 100ml or less

Tip: If you want to bring larger quantities of these foods, pack them in your checked baggage. Alternatively, purchase food and drinks after clearing the security checkpoint — post-security purchases are not subject to the liquids rule.

Baby Formula, Breast Milk, and Toddler Food

Baby formula and breast milk are explicitly exempt from the 100ml rule in most major countries, including the United States, United Kingdom, and European Union countries.

You may bring a reasonable quantity of formula or breast milk for the duration of the journey — no set volume limit, though "reasonable for the trip" is the standard. Security staff may ask to test the liquid using a test strip or device; this is normal procedure.

In the US (TSA): Baby formula, breast milk, toddler drinks, and juice are allowed in quantities exceeding 3.4oz. They must be declared at the checkpoint. Ice packs and gel packs used to keep breast milk cold are also exempt if the breast milk is present.

In the EU and UK: Similar exemptions apply. The liquid must be for feeding an infant during the journey.

Practical tip: Carry a letter from your doctor if you are travelling with medical foods, special formulas, or unusually large quantities.

Alcohol Purchased Duty-Free

Alcohol bottles purchased at airport duty-free shops after clearing security can be brought into the aircraft cabin in their sealed tamper-evident bags. The bag must remain sealed until you reach your final destination. Do not open the duty-free bag on the plane.

If you have a layover and must clear security again (this happens on many international connections), duty-free alcohol may be confiscated at that secondary checkpoint if the country you are transiting through has stricter rules. Check connection-point rules before purchasing large bottles at duty-free.

Hot Food

Hot food — takeaway meals, hot sandwiches, soup cups — is allowed through security. Solid hot food (a burger, pizza slice) passes without restriction. Liquid-based hot food like soup is subject to the 100ml rule.

Security officers may occasionally spend extra time on a container of hot soup or a meal in an opaque container, since the X-ray image is harder to read. This is not a reason to avoid bringing hot food — just expect the possibility of a brief additional check.

Agricultural and Customs Restrictions at Your Destination

Clearing security at the departure airport is only part of the picture. When you arrive at your destination country, customs rules may restrict or ban certain foods entirely.

United States (CBP): Fresh fruits, vegetables, plants, and certain meats from abroad may be seized at the border. The US Department of Agriculture (USDA) has country-specific lists of what is and is not permitted. Always declare any food you are carrying on your US customs form — failure to declare is a more serious offense than bringing a restricted item.

Australia: One of the strictest biosecurity regimes in the world. Fresh fruit, vegetables, seeds, nuts, meat, and dairy products from most countries are prohibited or require declaration and inspection. Fines for undeclared biosecurity items start at AUD 222 on the spot.

New Zealand: Similar to Australia. Very strict on fresh produce, meat, honey, and plant material.

European Union: Restrictions on meat and dairy from outside the EU, particularly from non-EU countries. Fruit and vegetables from outside the EU are allowed in small personal quantities.

General rule: When travelling internationally, consume or discard fresh food before landing, or declare it at customs. Declaring an item you are unsure about is always better than being caught with an undeclared restricted item.
