Flying With a Baby: A Calm Guide

The FAA's guidance is clear: the safest place for a baby on a plane is in an FAA-approved child restraint — a car seat — secured in their own purchased seat. Turbulence is the main reason; a lap held tightly cannot hold a baby through sudden, severe turbulence the way a harness can. Airlines allow babies under two to fly free on a lap, and many families do, but the FAA strongly encourages a seat of their own with an approved restraint. Everything below assumes you want to fly as calmly and safely as possible.

This is aviation safety guidance, not medical advice — for questions about whether your baby is ready to fly, ask your pediatrician.

The safest setup: a car seat in its own seat

Most infant and convertible car seats are certified for use on aircraft — look for a label on the seat that says it is "certified for use in motor vehicles and aircraft." If your seat has that label, you can buy a seat for your baby and install the car seat on the plane much as you do in the car; a window seat is usually required so it does not block another passenger's path to the aisle. Because your baby already rides in this seat in the car, it is also familiar, which often helps them settle.

If you are still choosing gear, note that a lighter, travel-friendly seat is easier to carry through an airport. Our roundups of the best infant car seats and best convertible car seats flag which seats carry the aircraft-approval label and how heavy they are.

When a lap infant or bassinet makes sense

Flying with a baby on your lap is allowed for under-twos and costs less, and for short trips or tight budgets many families choose it. If you do, hold the baby securely and keep them in your arms during takeoff, landing, and any turbulence; a baby is never buckled into the adult seat belt with you.

On some long-haul wide-body flights, airlines offer a bulkhead bassinetthat attaches to the wall for babies under a certain weight. These can make a long overnight flight far more comfortable, but they are limited in number, must be requested in advance, and the baby has to be removed and held during turbulence. Ask the airline directly — policies and weight limits vary by carrier and aircraft.

Gate-checking strollers and car seats

You can almost always bring your stroller and car seat right up to the aircraft door and gate-check them for free — they are handed back to you at the door on arrival, which is ideal for a connection or a long walk through the terminal.

• Strollers: a compact travel stroller is a huge help in an airport. A lightweight frame is easier to fold one-handed at the gate; our best strollers roundup includes travel-friendly picks.
• Car seats: if you are not using the seat on the plane, gate-check it or check it with your bags. A padded car seat travel bag protects it from damage in transit.
• Protect against damage: gate-checked gear is generally handled more gently than hold luggage, but a bag or cover still helps. Inspect a checked car seat on arrival; if it was dropped hard, treat it with the same caution you would after a car crash.

Getting through security

TSA has specific accommodations for families, and you do not have to send the baby through anything alone. A few things that make screening smoother:

• You carry the baby through the metal detector— babies are not sent through screening equipment alone. You may be asked to remove them from a carrier.
• Strollers and carriers are screened separately on the belt, folded, so practice a quick fold beforehand.
• Formula, breast milk, and baby food are allowed in reasonable quantities above the usual liquid limit. Tell the officer you have them; they may be screened separately.
• Give yourself extra time. Families can often use a family lane. There is no need to rush.

Comfort in the air

Cabin pressure changes during takeoff and descent can bother little ears. Feeding, a pacifier, or simply sucking helps a baby equalize pressure, so timing a feed or offering a pacifier during climb and descent can prevent a lot of tears. Dress the baby in easy layers, pack more diapers and wipes than you think you need in your carry-on, and bring a spare outfit for both of you. A baby carrier keeps your hands free in the terminal and on the jet bridge — see our best baby carriers.

A calm packing mindset

You do not need to bring everything you own. Pack the essentials for the flight in an easy-to-reach bag — diapers, wipes, feeding supplies, a change of clothes, a pacifier — and check the rest.
