Flying With a Newborn: What to Know in the First Months

The first months are the easiest time to fly with a baby in some ways, since newborns sleep almost constantly and feed on demand, and the hardest in others, since they are tiny and brand new. This is the newborn-specific version: when it is safe to go, what airlines require, and what actually matters once you are on board. For older babies, see our broader flying-with-a-baby guide.

Is it safe to fly with a newborn?

For a healthy, full-term newborn, flying is generally fine once your pediatrician gives the go-ahead, but the timing is a medical question, not a travel one. Premature babies and any newborn with health concerns need a doctor’s clearance first. The bigger reason many families wait a few weeks is the immune system, not the flight itself.

Airline age rules and tickets

Most US airlines set a minimum age to fly, often around 2 to 14 days, and some require a doctor’s letter for the youngest newborns. Under 2, your baby flies as a lap infant for free domestically (a small fee or tax internationally), or you can buy a seat and use an FAA-approved infant car seat, which is the safest option.

  • Check your specific airline’s minimum infant age before booking; it varies, and the youngest ages may need a physician’s note.
  • For international trips, the newborn needs their own passport, which can take weeks, so apply the moment you have a birth certificate.
  • Domestic US flights do not require ID for an infant, but carry a copy of the birth certificate just in case.
  • On long or overnight flights, buying a seat for an FAA-approved car seat is worth it; for short hops, lap is usually fine.

The takeoff-and-landing trick

Pressure changes are the one predictable discomfort. The fix is the same at every age: have the newborn sucking during takeoff and the start of descent. Nurse, offer a bottle, or use a pacifier, and time a feed for the climb rather than feeding at the gate. Most ear fuss is brief.

Gear that earns its place

With a newborn you need less than you think. A carrier and a safe place to sleep do most of the work.

A newborn-sized soft carrier keeps the baby snug against you through security and the terminal, and rocks them to sleep on board. The single most useful thing you will bring.

FAA-Approved Lightweight Infant Car Seat

If you buy the baby a seat, a lightweight FAA-approved infant car seat is the safest spot on the plane and doubles as your car seat at the destination.

For the destination, a foldable travel bassinet gives the newborn a safe, familiar place to sleep instead of an unknown hotel crib.

Protecting a newborn’s health on the trip

  • Wash and sanitize hands often, and gently discourage strangers from touching the baby; a newborn’s immune system is still developing.
  • Wipe down the tray table and armrests, and keep the baby in the carrier rather than on shared surfaces.
  • Bring more diapers than you expect (one per hour of travel plus extras), wipes, two changes of clothes for the baby and a spare top for you.
  • Keep feeding on demand; air travel is dehydrating, so a newborn may want to nurse or take a bottle more than usual.

Where a first trip is easy

For a newborn’s first trip, keep the flight short and the destination calm and warm. These keep travel time down and score well for families:

Common questions

How old should a newborn be to fly?

It depends on the airline and your pediatrician. Many US airlines set a minimum of roughly 2 to 14 days, sometimes requiring a doctor’s note for the youngest, and many families wait a few weeks for the immune system rather than for the flight itself. Always clear the timing with your pediatrician first.

Do I need a ticket for a newborn?

Under 2, a newborn can fly as a lap infant, free on domestic US flights and usually a small fee or tax internationally. You can instead buy a seat and use an FAA-approved infant car seat, which is safer and well worth it on long or overnight flights.

How do I protect a newborn’s ears when flying?

Have the baby sucking during takeoff and the beginning of descent by nursing, bottle, or pacifier. This equalizes ear pressure and prevents most discomfort. Time a feed for the climb rather than feeding while still at the gate.

Does a newborn need a passport to fly?

For international travel, yes, the newborn needs their own passport, which can take several weeks to issue, so apply as soon as you have a birth certificate. Domestic US flights do not require ID for an infant, though carrying a copy of the birth certificate is wise.
