How Old Does a Baby Have to Be to Fly?

I’ve been asked when can a baby fly many times and have researched several official airline policies to help you. Whilst waiting for your little one to arrive, you may be dreaming of warm vacations/holidays to relax and enjoy your new bundle of joy; but the first question to enter your mind is: when can a newborn fly and what do I need to do in advance to ensure they are kept safe?

We planned to travel when our first baby was a newborn and spent a lot of time researching this question, in case it limited our choice of destination, airline or meant some additional paperwork essentials were required.

When Can A Baby Fly?

From speaking to other parents, it was clear the process and experience varies depending on the airline. We have found newborn policies ranging from 1 day to 14 days.

There is no minimum age for when newborns are legally allowed to travel, although most medical professionals, including the American Academy of Pediatrics advise you should avoid flying with your newborn until they are at least 7 days old.

The UKs NHS states that restrictions and rules can vary between airlines, so if you are in any doubt, you should seek advice from the medical department of the airline and your doctor or pediatrician.

This guide goes through 20 airlines policies which answer the question: What age can a baby fly on an airplane and what are the regulations? The policy for each airline on how old does a baby have to be to fly, varies widely as you can see below.

(For essential tips for flying with a baby, see here.)

When you fly, you will have the option of purchasing a seat for your baby (at a charge and with the use of your car seat), or flying with your baby on your lap (often known as a lap baby or lap infant at a vastly reduced fee). On some flights, airplane bassinets will be available. All passengers requiring them, usually need to request in advance.

Most airlines stipulate certain air travel regulations or rules for flights with infants. For example, on British Airways an infant will have to be over 6 months old to sit in your airline approved car seat, whereas other do not have this rule.

For all airlines, if you are flying with more than one infant and flying by yourself, you will need to purchase at least one seat with an airline approved car seat to fly as you cannot fly with two children on your lap.

Usually, the cabin crew can help you with your car seat and fitting it on the airplane. Most airlines will let families with babies and small children begin the boarding process early on. We cover all the essentials you need to know.

Air Canada

Babies can fly from 7 days old with Air Canada. The airline only permits one child to fly per adult and the infant can travel for free for domestic flights within Canada and to/from the United States if this child sits on the lap of said adult.

You are able to purchase a seat for the child if there is an adequate child restraint device, however these are not permitted in Executive First Class. For flights outside of the US, the fare for an infant on a lap is 10% of an adult fare and a child fare applies for the infant to have their own seat.

Air Canada allow two pieces of baggage to be checked in plus one carry on bag and one stroller which can be checked in at the gate. Air Canada suggest checking any bookings to ensure that seat reservations and assignments to ensure that you are provided with a seat in proximity to any children. As much formula or breast milk needed for the journey is permitted.

Alaska Airlines

Alaska Airlines have no minimum age requirement for a baby to fly on one of their flights, however they do suggest checking with the child’s doctor or pediatrician to ensure that the journey is safe for your newborn.

Children must occupy their own seat on the airline once they reach 2 years of age and until then, can be placed on an adult’s lap – you must inform the airline of this and the adult must be at least 16 years of age.

There are no applicable taxes for lap infants for domestic flights but there is an immigration tax when a lap infant is travelling from Canada or Mexico.

For air travel with American Airlines, you may be asked to show proof of age (a birth certificate) for any child under 18 years old. Baby can fly from as young as 2 days old to travel however if the infant is under 7 days old, your doctor or pediatrician must fill in a form prior to the flight.

On British Airways, newborn babies must be at least 48 hours old and have been born without any complications before they can travel with them. They advise you to check with your treating doctor that they agree to both you and your baby travelling.

If you have had a Caesarean section or if other surgery was needed during or after the birth, then you can travel after 10 days, with medical clearance from British Airway’s Health Services. We would advise that your treating doctor or pediatrician approve your travel first.

British Airways also suggest checking which travel documents you need prior to travel dependant on the country you are visiting as some immigration departments require additional documentation. Each county’s embassy website can provide you with this information.

Infants are permitted to sit on the lap of anyone over the age of 15 or in their own seat and the price will be dependant on this (an infant fare is a percentage of an adult fare when seated on your lap but a child fare applies for an infant with their own seat).

Flying With A Newborn Health Considerations

When flying with a newborn, it is important to consider how to keep them safe and healthy as their immune system is still developing.

Antibacterial wipes can be used to clean surfaces and pacifiers/dummies or breastfeeding can help to protect their ears. If your child has a cold or any other illness before flying, it is important to contact your doctor for further advice.

Vaccinations are often needed to travel to various countries and can be needed to be administered one month prior to travel. These are dependant on the location you are visiting and some vaccinations will be part of the usual given to children at specified stages of their early childhood.

Sometimes these schedules can be sped up if urgent travel must be made and your doctor must be contacted to ensure that your child is covered completely for your journey.

Vaccinations and schedules can differ in different countries, private provision can provide these for you and the World Health Organisation can offer additional advice for you.

Each airline, and even Health Professionals may have differing views when answering the question of how soon can a baby fly after being born as there is no legal requirement or minimum age.

It is important to check any documentation needed for each flight, bring prescription medicine with you and any medical certificates depending on destination.

Additional documentation will vary dependant on the airline. If your baby is nearing two years of age prior to travel, you must check with your airline about pricing and seating arrangements if they will turn two during part of the journey or before the return flight.

Please do verify with your airline before booking in case there any changes since we last updated this page.
