<p>A plane cabin is dry, shared and hard to leave for a few hours. You can't make a flight germ-free, and nothing will boost your child's immunity for the trip. But simple habits can make it more comfortable and cleaner. This guide covers what health bodies say and how to put it into practice.</p>
Last reviewed: November 2026. This guide draws on the US Centers for Disease Control and Prevention (CDC) Yellow Book 2026 chapter on air travel (April 2025), the CDC’s hand sanitiser guidance (March 2024), the NHS and the American Academy of Pediatrics (AAP). It’s general information, not medical advice. No product or habit here can guarantee that your child won’t get ill, and nothing on this page boosts immunity. Ask your doctor about your own child.
Air travel with children brings together a lot of little discomforts. The air is dry, armrests and tray tables are shared, and the toilets are small. A child might be hot, then cold, then sticky, then bored. It’s easy to find advice online that promises to protect your child, but the sources we checked are more modest. They say what you’d expect: wash your hands, stay home if you’re ill, and don’t overthink it. Here’s how that works in the cabin, along with the practical things that make a flight more comfortable.
Quick answer
- Soap and water first: the CDC says that washing with soap and water is the best way to get rid of germs in most situations. It says travellers should wash their hands frequently and thoroughly.
- Sanitiser as a backup: use one with at least 60% alcohol when soap and water aren’t available, and watch young children using it.
- Dry air: the CDC says cabin air is typically dry, at around 10 to 20% humidity, which can dry out the nose, throat and eyes.
- Ill before you go? The CDC says people with confirmed or suspected acute respiratory infections should delay travel.
- Ears: the AAP suggests feeding or a dummy during take-off and landing.
- Be realistic. You can lower some risks, but you can’t remove them.
What the CDC says about the cabin
Parents often worry about the air on a plane. The CDC Yellow Book says recirculated cabin air passes through high-efficiency particulate air (HEPA) filters, and that the cabin air is refreshed much more often than in most office buildings. But it also says that communicable diseases can be transmitted during air travel, and that respiratory viruses such as measles have been documented on commercial aircraft. So filters help, but they don’t remove every risk, particularly from people close by.
It suggests good handwashing and respiratory hygiene, and says that masks or respirators, especially during boarding and getting off the plane, may also reduce transmission. Whether a mask makes sense for your child depends on their age and your doctor’s advice.
Step-by-step checklist
Before you fly
- Check that everyone is well. See our guide to travelling with a sick child if someone isn’t.
- Dress your child in layers. The AAP suggests packing several changes of clothing in layers, because cabin temperatures can vary.
- Pack a hygiene pouch in your under-seat bag: wipes, a small sanitiser, tissues, a small towel and a plastic bag for rubbish.
- Bring a change of top for each adult. Sick and spilled milk don’t stop at the child.
- Change a nappy just before boarding. The AAP suggests this to save a trip to the cabin toilet.
Our under-seat bag packing list covers the rest.
At your seat
- Wipe what your child will touch, if you’d like to. That means the tray table, armrests and seat-belt buckle. We didn’t find guidance that says this prevents illness, but it may help with stickiness and spills.
- Use your own cover for the tray, such as a clean muslin, if your child eats directly from it.
- Keep dummies and toys clean. Clip-on holders can help keep them off the floor, but check that they’re suitable for your child’s age, and that the cord is short.
- Offer drinks regularly. Breast or bottle for babies, and water for older children.
Hands
The NHS says to wash your hands for around 20 seconds, which is about as long as singing “Happy Birthday” twice. The CDC steps, quoted by the AAP, are to wet hands, apply soap, rub vigorously and scrub every surface, rinse and dry. It’s a lot to do in a plane toilet with a small child, so choose your moments:
- After going to the toilet, and after every nappy change. The CDC says parents should be especially careful about this.
- Before feeding a baby, or before a meal.
- After coughing or sneezing.
- When you get off the plane, which is often the first good chance for a proper wash.
Sanitiser and wipes
The CDC says to use soap and water where possible, as it removes all types of germs, while sanitiser kills only certain germs on the skin. If soap and water aren’t available, it advises a sanitiser with at least 60% alcohol. It also says that adults should watch young children using it, to prevent them from swallowing alcohol. In practice, that means applying it for them and letting it dry fully before they put their hands in their mouths. Keep the bottle out of reach, and check the liquid rules for your airports. Our guide to airport security with children explains more.
Staying comfortable
Dry air and drinks
The CDC says that the dry air can cause dryness in the airways and eyes. It doesn’t say that this leads to dehydration, and we haven’t found a recommended amount to drink for children on planes. The sensible thing is to offer drinks regularly and watch for the usual signs. The NHS says that babies and children are more at risk of dehydration, and lists fewer wet nappies, dark pee, sunken eyes and tiredness as signs. A leakproof bottle and a simple lip balm may help older children. Check with a pharmacist about products for babies.
Ears
The AAP says that the noise is loudest at take-off, and suggests breastfeeding, a bottle or a dummy during take-off and landing to help with ear pressure. The CDC notes that ear pain can be troublesome for children during descent, and that antihistamines and decongestants haven’t been shown to help. If your child has a cold or ear infection, it says that those with ear, nose and sinus infections or severe congestion may choose to postpone flying.
Temperature and clothes
Plan for changes in temperature. Layers you can remove work better than a thick jumper, and your child’s feet may get cold when they’re not walking about. Keep a blanket on hand for older children, but remember the AAP’s safe sleep advice for babies: keep the head uncovered and use a firm, flat surface when you can.
Moving about
Take a walk when the seat-belt sign is off, as it helps restless children. Keep your child buckled in when the sign is on. The AAP says turbulence is the leading cause of injury to children on planes. Keep shoes on near the toilet, and bring a small pack of tissues for them, in case the paper runs out.
Common mistakes and real-world scenarios
- Relying on a “immune-boosting” product. We didn’t find any health body that recommends one for flights. Don’t spend your money on the promise.
- Using sanitiser on a sticky hand. Wipe off the food first, then use it, or wait until you can wash. It’s best on hands that aren’t visibly dirty.
- Flying with a fever. Don’t assume a dose of medicine will solve it. See our guide on when to delay.
- A dropped dummy. Wash it or use a clean spare. Pack a few.
- A nappy change on the seat. Use the changing table in the toilet if there is one, and ask the crew for help if not. Don’t change a nappy on the tray table.
- Too much cleaning. Don’t let wiping everything take over the flight. A few habits at the right moments will do.

Final thoughts
<p>Wash hands well before eating and after the toilet, use sanitiser when you can't, offer drinks regularly and dress your child in layers. Nothing guarantees that your child won't catch something, and if someone in your family has a respiratory infection, the CDC says to consider delaying. Ask your doctor if your child has a health condition.</p>
Frequently asked questions
Are plane germs worse than anywhere else?
The CDC says that cabin air passes through HEPA filters, but that diseases can still be transmitted during air travel. Being close to others for a long time is part of the risk.
Is hand sanitiser OK for children?
The CDC advises at least 60% alcohol when soap and water aren't available, and says that adults should watch young children using it, so that they don't swallow it.
How can I stop my child getting ill on a flight?
You can't guarantee it. Good hand washing and respiratory hygiene are what the CDC suggests. Ask your doctor about masks or vaccinations.
Does the air on planes dehydrate children?
The CDC says the air is dry, but it doesn't directly discuss dehydration. Offer drinks regularly, and watch for the signs of dehydration that the NHS lists.
Should I wipe down the seat?
You can if you'd like to. We didn't find guidance that says it prevents illness, so it shouldn't replace hand washing.
