How old does a baby have to be to fly? It's a common question for families, especially those who love traveling. The good news is that you can fly with them once they are 7 days old. But you should not stop your research at knowing just that. You must learn how to keep them safe and know about the other considerations. Continue reading to know more about these.

How Old Does a Baby Have to Be to Fly?
A baby can fly as early as 7 days old. If you want to fly when they are younger, you may need to get proof that your pediatrician has approved the trip. However, experts recommend waiting 2 to 3 months before flying. That's because planes and airports are full of people. Since a baby's immune system is still developing, being in these places increases the risk of catching infectious diseases.
Keep in mind that airlines may have their own policies, so be sure to check that.
What to Consider Before Flying with a Newborn?
Here are the factors you need to consider when you're planning to fly with your baby.
- Age - You should ensure your baby is no younger than 7-days-old.
- Medical condition - Consult a pediatrician before booking a flight with your baby.
- Baby Carrier - You would need your hands to be free while at the airport. Using a baby carrier helps make this possible.
- Time - We recommend booking flights that match your baby's naptime.
- TSA Rules - Liquid limits in airlines do not prohibit breast milk, formula, and water. However, you must declare them, and they should be screened separately.
- Travel Essentials - Strollers and car seats are travel essentials for babies. They often don't count as luggage, but you should confirm this with the airline.
Preparing for a Flight
Here are some tips on how to prepare for a flight with your little one.
a. Breastmilk and Formula Milk Allowance
Formula and breast milk are exempt from the 3-1-1 rule. However, you should keep them in reasonable quantities. Estimate how many bottles you would need and bring a little more than that for possible delays.
Also, keep in mind that bottles are the best container choice because they screen faster than bags.
b. Luggage Allowance for Infants
The luggage allowance for infants varies depending on their ticket. For lap infants, you can typically bring one piece up to 10 kilograms. On the other hand, you can bring more for infants with tickets. The allowance is usually printed on your ticket, so be sure to check it.
c. Pushchairs, Strollers and Slings
Most airlines allow you to bring collapsible pushchairs, strollers, and slings. Your best option is the Momcozy ClickGo Lightweight Stroller. It only weighs 19 lbs, and it is very compact when folded. As such, this stroller is carry-on approved. You can also pick it up via the removable bumper bar with one hand, so it is easy to carry.

Keeping the Baby Comfortable on the Flight
Your baby's comfort is as important as their safety during flight. Here are the factors that you need to keep in mind:
Bassinets / Sky Cots
Many airlines offer bassinets or sky cots on long-haul flights. These provide a safe place for your baby to rest and sleep, allowing both you and your baby to be more comfortable during the journey.
Baby Changing
Most aircraft are equipped with baby changing tables, usually located in the lavatory. Knowing where these are and planning diaper changes in advance can make the flight much easier and less stressful.
Ear Pain
Changes in cabin pressure during takeoff and landing can cause ear discomfort for babies. Feeding, breastfeeding, or offering a pacifier during these times can help reduce pressure and keep your baby comfortable.
Which Seat on the Plane Is Best for a Baby?
The best plane seat for your baby varies depending on some factors. Here's what you need to know:
Bassinet
Suppose you want to use a bassinet. If that's the case, the bulkhead window seat is the best one for your baby. Bassinets can attach to the bulkhead, and that would give your baby a flat space to sleep in. However, please note that these seats are very limited. As such, we recommend that you contact the airline immediately after booking your flight to send a request.
Car seats
You can go with either a window seat or a seat near the front. With a window seat, you can keep your baby away from the aisle and distractions. More importantly, you can keep them away from carts and overhead bin items, so it is safer for them.
Lap Infants
Near the restroom sounds like a good spot, but this is a trap. It's noisy and very busy, so it is full of distractions. An aisle seat that's a bit far from the restroom is a better choice. It still allows you to go to the restroom quickly, but the surroundings are not as busy. Be sure to protect them from passing beverage carts, though.
Window seats are also good options. It gives you more privacy and minimizes distractions.
Risks of "Infant in Arms"
Deaths of infants while flying are rare. However, a study has found similarities in those cases where an infant died. Many of these are lap infants. The researchers suspect that the primary factors include co-sleeping arrangements with adults, as well as sharing a seat for a long time. The low oxygen levels may have also contributed to these deaths.
That said, it is recommended that you use a car seat instead. Just ensure your car seat is narrow enough to fit the airplane seat. It should be around 16 inches. Also, check if you can lift the armrest.
How to Keep Your Newborn Safe When You Fly?
You can keep your baby safe with smart preparation and simple habits that reduce stress and risk throughout the flight.
Use a Baby Carrier
We recommend using a baby carrier in the airport. Baby carriers free up your hands while moving through security, boarding, and crowded terminals. It also reduces the chance of accidental bumps or drops compared to carrying your baby in your arms.
A carrier also keeps your newborn close to your body, which helps keep them calm and comfortable. It also supports their head and neck, ensuring they are safe.
One of your best options is the 2-In-1 Hip Seat Baby Carrier. It easily adapts to your baby's needs. This baby carrier can support them while they are active and while they are resting. The wide, stable seat also keeps your baby comfortable and in a natural sitting position. Thus, it is safe to use. This baby carrier also features an X-shaped shoulder design that help reduce pressure on your waist and abdomen. You will surely appreciate that since you are also carrying a lot of other things when traveling.

Use a Car Seat
During the flight, always secure your baby properly. If your newborn is traveling as a lap infant, follow the airline's safety instructions carefully. You must keep them in mind, especially during takeoff, landing, and turbulence.
For more peace of mind, experts recommend using an approved infant car seat. It is safer for your baby and makes them more comfortable.
Practice Good Hygiene
Practice good hygiene throughout the trip. Wash or sanitize your hands frequently, and limit your newborn’s contact with surfaces and other passengers when possible. This helps reduce exposure to germs in busy airport environments.
Pack Wisely
Finally, pack essential items in your carry-on. Diapers, wipes, extra clothing, feeding supplies, and comfort items should be easy to reach so you don’t need to stand up or search through overhead bins while holding your baby.
FAQs
Here are some more frequently asked questions related to "when can a newborn fly internationally?"
a. What Documents Will My Baby Need?
- Birth Certificate - Their birth certificate is always needed. It shows that your baby is old enough to ride a plane and young enough to fly free or pay a reduced fare.
- Parent's ID - Your government ID is also needed to prove your relationship.
- Consent Letter (Situational) - Suppose your baby will be traveling with a guardian or only one parent. Then, a notarized consent letter from the other parent is also needed.
b. Does My Baby Need a Passport for International Travel?
Yes. Babies who are traveling internationally need passports. On top of that, the airline may also ask for a medical release, especially for children under 14 days old.
c. Do I Need to Buy an Airplane Ticket for My Baby?
Usually, the answer is yes. But there are some instances when it is free.
For lap infants in domestic flights, tickets could be free or have a small fee. International flights, on the other hand, sell tickets that are 10% of the adult fare plus taxes and fees.
For infants with seats, you will need to pay the child fare. The price is sometimes discounted.
d. What’s the Best Time of Day to Fly with a Baby?
The time when your baby usually sleeps is the answer. That said, it is usually at night or during their midday naps. Note that your baby's behaviors also affect this. So, check whether they are poor morning sleepers or light sleepers.
e. How Should I Dress My Baby on the Flight?
You should dress them in soft, layered clothing. This allows you to easily adjust it when the temperature in the cabin changes. When the temperature goes high, remove layers. When it's cold, add the removed layer back.
You should also pick clothes that allow for easy diaper changes.
f. What Should I Do with the Stroller?
You have three options. You can check it at the ticket counter or drop it at the jet bridge. These options help reduce the items you are carrying. However, the risk of damage is higher in these options. The third option is to bring the stroller onboard. This option is only available if your stroller is compact, like the Momcozy ClickGo Lightweight Stroller.
Where Can I Change My Baby’s Diaper on a Flight?
You can change your baby's diaper in the lavatory. In international flights, you can also expect at least one restroom with a changing table that folds down over the toilet. For smaller planes, however, you may need to make do with the closed toilet seat. We recommend bringing a travel changing pad or mat to make the experience more sanitary.
