In this guide, we’ll answer some common questions parents have before takeoff and share practical, stress-saving tips for flying with a baby — from going through security to landing. 

Airline fees, restrictions and allowances for infants 

When is it safe to fly with a baby? 

Most airlines allow babies as young as two days old to fly, but pediatricians often recommend waiting until your baby is at least two to three months old. At that point, their immune system is a little stronger, and they're better able to handle the changes in air pressure. 

Flying with a newborn too early can increase the risk of illness, especially in a crowded airplane cabin. And while rare, some babies may have trouble equalizing ear pressure, which can be painful during takeoff and landing. 

If you’re unsure, check with your pediatrician before booking your trip. They'll know what’s best based on your baby's health and age. 

How to fly with a baby: 17 tips 

Here are 17 tried-and-true tips to make flying with your baby smoother from gate to gate. 

1. Book flights around nap times 

When possible, try to fly when your baby normally sleeps. A well-timed nap in the air can mean a quieter, calmer flight for both of you. Even if they don’t sleep the whole time, they may be more relaxed. 

2. Reserve seats early 

Lock in your seats early to get the best setup for your family. If you're traveling with someone else, booking the aisle and window with the middle open can sometimes score you an empty seat. Solo with a baby? An aisle seat makes getting up much easier. Check out our guide on the best airplane seats when making your choice. 

3. Decide whether to buy a seat for your baby 

Babies under 2 can fly for free on your lap, but having a separate seat (with an FAA-approved car seat) gives you space and security. If it’s a long flight or overnight, the added comfort can be worth the cost. Some parents swear it makes the trip more manageable. 

4. Know your airline’s policies 

Each airline has different rules about baby gear, lap infants, and early boarding. Some let you gate-check a stroller and car seat for free, others don’t. Look it up before flying so you’re not surprised at check-in. When in doubt, check out the chart at the top of this page! 

5. Bring a baby carrier 

A soft carrier helps you go hands-free through security, boarding, and walking the aisles. It’s also a great way to soothe your baby if they get fussy during the flight. Plus, it keeps your hands free for handling bags and tickets. 

6. Arrive at the airport early 

Give yourself plenty of buffer time to arrive for your flight. Diaper changes, feedings, security checks—all take longer with a baby in tow. Showing up early keeps the stress level down and gives you time to regroup if needed. 

7. Feed during takeoff and landing 

The sucking motion from breastfeeding, bottle-feeding, or using a pacifier can relieve ear pressure. It helps your baby adjust to changes in altitude and can prevent discomfort. Time it right so they’re actively sucking as the plane climbs or descends. 

8. Change diapers before boarding 

A pre-boarding diaper change means one less thing to worry about in a cramped airplane bathroom. Airport restrooms often have larger changing tables and more space to maneuver. Even if it’s just a quick check, it’s worth doing. 

9. Know how to change a diaper on a flight 

Most long-haul or larger planes have at least one bathroom with a fold-down changing table—usually in the rear. If not, ask the crew where they recommend you change your baby’s diaper. Bring a compact pad and diaper clutch so you’re not juggling your whole diaper bag in a tight space. 

10. Pack smart in your carry-on 

You’ll need more than you think. Stock your carry-on bag with diapers, wipes, snacks or formula, extra outfits (for both of you), a swaddle or blanket, and small toys. Keep essentials within reach and group items in clear pouches for easy grabbing. 

11. Dress your baby in layers 

Cabin temps can swing from chilly to stuffy. Dress your baby in soft, breathable layers so you can easily add or remove clothing as needed. Zip-up onesies or rompers make diaper changes easier, too. 

12. Accept help from the flight crew 

Flight attendants are there to assist—so let them. Whether it’s warming a bottle or holding your coffee while you settle in, a little help can go a long way. Don’t hesitate to ask if you need something. 

13. Walk the aisle if baby gets fussy 

A little motion and a change of scenery can help calm a cranky baby. Just make sure the seatbelt sign is off and stay aware of food carts and other passengers. Sometimes, just a quick lap is enough to reset your baby’s mood. 

14. Don’t stress about crying 

Crying happens—even to the best-prepared parents. Focus on soothing your baby and try to stay calm yourself. Most people understand, especially other parents who’ve been in your shoes. 

15. Skip the bulk of toys 

Babies don’t need a suitcase full of entertainment. A few favorites, like a teether or soft book, will do just fine. Many babies are fascinated by new sights, seatbelt buckles, and snack wrappers anyway. 

16. Plan for delays 

Flights don’t always go as scheduled, so pack for the unexpected. Bring more diapers, food, and clothes than you think you’ll need. Having extras on hand will save you if you’re stuck waiting at the gate or delayed on the runway. 

17. Be the last to board (sometimes) 

If you don’t need overhead space, waiting until the end of boarding can minimize how long your baby has to sit still. But if you need time to get settled or store gear, early boarding is still a good option. Choose what works best for you and your baby. 

Planning your next getaway? 

Traveling with a baby can feel intimidating—but it doesn’t have to be. With a bit of prep, the right gear, and a flexible mindset, you’ll be ready to take off with confidence.
