<p>Snacks are often what gets a toddler through a flight. This guide covers the three places they can go wrong: the security checkpoint, customs at the other end, and the seat-back tray, where choking risks matter more than usual because space is tight and children are moving.</p>
Last reviewed: November 2026. This guide draws on the US Transportation Security Administration (TSA) pages on solid foods, fresh fruit and vegetables and travelling with children, GOV.UK pages on hand luggage liquids, baby food and bringing food into Great Britain, US Customs and Border Protection (CBP) “Prohibited and Restricted Items” (March 2025), the NHS page “Foods to avoid giving babies and young children” (February 2026) and an NHS Healthier Together page on choking. Rules change and officers have the final say, so check before you fly.
A bag of snacks is one of the most useful things you can carry for a toddler on a plane. It fills time, it gives a restless child something to do, and it gets you through delays. But snacks run into three different sets of rules: security at departure, customs and biosecurity at arrival, and basic food safety for small children. This guide takes them in order.
Quick answer
- Solid snacks: the TSA says solid food can go in carry-on or checked bags. Officers may ask you to take food out of your bag for screening.
- Pouches and purees: the TSA treats baby food, including pouches, as an exception to its liquids limit. Tell the officer you have them.
- Yoghurt, dips and spreads count as liquids or gels at security. The TSA says liquid or gel food over 3.4 oz shouldn’t go in carry-on bags, unless it’s covered by the baby food exception.
- On arrival: CBP says you must declare all agricultural items when entering the US, and that it’s best not to bring fresh fruit or vegetables. Great Britain allows some foods, such as biscuits and bread, from any country.
- Safety: the NHS says whole nuts shouldn’t be given to children under 5, and an NHS Healthier Together page says grapes should be cut lengthways.
Part 1: Getting through security
US (TSA)
- Solid food can go in carry-on or checked bags, according to the TSA’s solid foods page. It says officers may tell you to take foods and powders out of your bag so they don’t obstruct the X-ray image, and that the final decision rests with the TSA officer.
- Liquid or gel food over 3.4 oz shouldn’t go in carry-on bags, and should be put in checked bags if possible, according to the TSA.
- Baby food, including pouches, is allowed above 3.4 oz, according to the TSA’s page on travelling with children. Tell the officer at the start of screening, and you don’t need to put it in the quart-size bag. The same applies to formula, breast milk and toddler drinks.
- Ice packs and gel packs for keeping these items cool are allowed, and so are liquid-filled teethers, according to the same TSA page.
- Fresh fruit and vegetables are allowed in carry-on bags within the continental US. The TSA says passengers flying from Hawaii, Puerto Rico or the US Virgin Islands to the mainland can’t take most fresh fruit and vegetables.
UK
- Liquids: GOV.UK says containers of 100ml or less apply at most airports, in a single clear bag. Check each airport on your route, because some now allow more.
- Baby food and milk: GOV.UK says you can take enough baby food and baby milk for the journey, in hand luggage, when the baby is travelling with you. Each container is screened and may be opened.
For the full picture on formula, milk and pumps, see our guide to flying with formula, breast milk and pumps, and our comparison of airport security for children in the US and EU.
Part 2: Customs and biosecurity on arrival
This is the part families most often forget. Food that sails through security at departure can be a problem at your destination.
Arriving in the US
- CBP says all agricultural items must be declared and presented for inspection. It says the civil penalty for failing to declare agricultural items is $300 for a first offence and $500 for a second.
- CBP says it’s best not to bring fresh fruit or vegetables into the US.
- It says fresh, dried or canned meats and meat products generally can’t be brought in from most foreign countries, and that food prepared with meat is generally not admissible.
- It says bakery items and certain cheeses may be brought in, and that many prepared foods are admissible.
- The CBP page we read doesn’t mention baby food or formula, so declare it and ask.
Arriving in Great Britain
- GOV.UK lists foods you can bring in from any country without restrictions, including bread (but not sandwiches filled with meat or dairy), cakes without fresh cream, biscuits, chocolate and confectionery (but not with a lot of unprocessed dairy), and pasta and noodles not mixed with meat.
- It says restrictions apply to meat, dairy, fish and animal products, and to fruit, vegetables, nuts and seeds. Check the detailed GOV.UK pages before you travel. Northern Ireland has separate rules.
Elsewhere
Many countries have strict biosecurity rules. We haven’t checked every destination, so look up the official customs or agriculture website for the country you’re flying to.
The simple rule: pack the fresh, meaty or milky snacks for the outbound flight and plan to finish them before you land. Keep packaged dry snacks for later.
Part 3: Safe snacks for small children
On a plane, your child is strapped in and often reclined or wriggling, and you’re squeezed in next to them. That’s a good reason to be careful with snacks.
- Whole nuts: the NHS says they shouldn’t be given to children under 5, because they can choke on them. Crushed or ground nuts can be added to food from around 6 months.
- Nut butter: the NHS says spread it on food such as toast, and don’t give it on its own.
- Grapes: an NHS Healthier Together page says babies can choke on something as small as a grape, and that grapes should be cut lengthways. It suggests cutting food into “batons” not “balls”.
- Hard foods: the same page says not to give young children hard foods such as boiled sweets or whole nuts.
- Raw jelly cubes: the NHS says they can be a choking hazard.
- Sitting still: the Healthier Together page says toddlers and young children should sit still while eating, with an adult staying with them. On a plane, that means snacks in the seat, not while walking up and down the aisle.
- Honey: the NHS says not to give it before 1 year old.
- Salt and sugar: the NHS advises limiting salty foods such as crisps and crackers for babies, and avoiding food and drink with sugar or sweeteners for children 4 or younger.
Pouches and travel feeders
Pouches are light, don’t need a spoon and pass through security under the baby food exception. A few practical points:
- Read the pack. Storage after opening differs between products, so follow the instructions on the pouch. If you can’t keep it cool, choose smaller pouches that your child can finish in one go.
- Spout or spoon. A reusable spoon attachment that screws on to a pouch can make it less messy for younger babies. Check the maker’s age guidance.
- Mesh and silicone feeders. These hold soft food for babies to chew. Follow the age guidance and supervise your baby while they use one.
- Tell security. Keep pouches together so you can take them out quickly.
Step-by-step checklist by age
| Age | Snack plan |
|---|---|
| Around 6 to 12 months | Pouches or jars, soft finger foods cut into batons, a spoon, bibs and wipes. Breast milk or formula as usual |
| 1 to 2 years | Soft finger foods, rice cakes or crackers in small amounts, fruit cut into batons, grapes cut lengthways. A spill-proof cup; see our leakproof bottles guide |
| 2 to 4 years | A wider mix in small containers, so you can hand out one at a time. No whole nuts |
| 5 and up | Let them choose some snacks and carry them in their own bag. See our kids’ under-seat bag list |
Common mistakes and real-world scenarios
- Burying snacks at the bottom of the bag. The TSA may ask you to take food out. Pack it at the top, in one pouch.
- Arriving with half a bag of apples. Finish fresh fruit before you land, or declare it.
- Not declaring food in the US. CBP fines start at $300 for undeclared agricultural items.
- Snacking in the aisle. Seated, supervised eating is safer.
- Packing only sweet snacks. The NHS advises avoiding sugar for children 4 or younger.
- No plan for a delay. Pack more than you think you’ll need. See our guide to long airport layovers with kids.

Final thoughts
<p>Solid snacks are generally fine through security; pouches and purees fall under baby food rules, so tell the officer. Plan to finish fresh fruit, meat and dairy snacks before you land, because customs rules on arrival are stricter than security rules. Pack snacks that suit your child's age, cut round foods lengthways, and make sure your child is sitting and supervised while they eat.</p>
