How Soon Can A Newborn Baby Fly?

Last Updated on

There are no standard regulations about how old a baby needs to be before they are permitted to fly.

Each airline has its own policies about what age a baby must be before it is allowed on its aircraft, you can see these policies in the table below.

Airline Rules About Traveling With Babies

When is it safe for a baby to fly?

Some airlines have no minimum age and others require approval from a physician before they will allow very young newborns onboard.

Babies can fly shortly after birth, but your airline allowing you to travel with a baby does not mean it’s a good idea.

Parents should think carefully about health and safety concerns and seek professional advice.

There is no age that it automatically becomes safe for traveling with a newborn. It very much depends on individual circumstances.

For example premature infants will not be ready to fly as quickly as full-term babies.

The mother also needs to be in good health. If you had your child by cesarean section you would need longer to be able to fly yourself.

Risks Involved In Traveling With A Newborn

  • Immunity – A newborn child has not yet developed a strong immune system. Airplanes are notorious places for picking up infections. You can try to sanitize your seat area using disinfecting wipes but the risk remains.
  • Turbulence – Many parents fly with a child on their lap. This avoids buying a separate seat for the child. While accidents are rare it’s fundamentally unsafe to fly with a baby in your lap, especially a newborn. To quote the FAA… “Your arms aren’t capable of holding your child securely, especially during unexpected turbulence.”. You can reduce the risk of injury through turbulence by purchasing a seat and using an approved child safety restraint system but the risk is not fully mitigated.

The Verdict

Seek professional medical advice before traveling with a baby, especially before flying with a newborn.

Newborn babies should only take plane trips that are absolutely necessary. If you can, postpone the trip until later.
