In addition to returning home or traveling, you may also use a plane with your baby when you return home to give birth.
I wonder if it's too much of a burden on my small body, when and how I can start riding, etc. Since rules and service content differ depending on the airline, we will introduce examples from ANA and JAL here.
*Please check each airline's website before using.

When can babies fly on planes?

Children can board both domestic and international flights from the 8th day after birth. At higher altitudes, the atmospheric pressure and oxygen concentration drop, which puts some strain on your body, but there's no need to worry as it won't affect your health. If you are concerned, it may be best to consult your family doctor before doing so.

Do I need an escort?

On domestic flights, infants under the age of 3 must be accompanied by a companion over the age of 12. For international flights, infants under the age of 2 must be accompanied by a companion who is at least 12 years old for ANA and 16 years old or older for JAL.

Up to two infants under 3 years old can travel with each adult on domestic flights, and up to 2 infants under 2 years old can travel together on international flights. If one adult is traveling with two infants, one can ride in a carrier, but the other must have a seat.

How do I make a reservation? What is the price?

Once you have decided to fly, we recommend that you book your ticket and select your seat as early as possible. Reservations and seat selections can be made on the airline's website or by phone.

Infants under 2 years old are free on domestic flights if seated on an adult's lap. If you use a seat, you will be charged the same child fare as children aged 3 to 12.
Even if you are carrying a baby without using a seat, please let us know that you are traveling with a baby when making your reservation.

On international flights, if you use a seat, you will have to pay the same fare as an adult, and even if you are carrying someone on your lap, you will still have to pay 10% of the adult fare.

Which seat should I choose?

Aisle seats are recommended. This is because it makes it easier to move around, such as soothing a fussy baby or standing up to change a diaper. When you need help from a flight attendant, it's easier to ask for help if you sit in an aisle seat.

It's best to choose a seat at the front, where there is less distance to travel when getting on and off, or at the back, where there is a restroom with a diaper changing table. There is a wide aisle space at the rear of the aircraft, so you don't have to worry about disturbing anyone when you hold and comfort someone, and the flight attendants are nearby, making it easy to get support.

Additionally, if you wish to use a baby cot (bassinet) on board, please make a reservation early as there are a limited number of seats available.

Can I bring a stroller on board?

There are restrictions on the size of carry-on baggage, so many strollers are too large to be carried on board.

If you are unable to bring a stroller with you, please leave it at the counter at check-in. At large airports, there are often long lines for baggage drop-off, but you can leave your stroller at a dedicated counter without lining up.
After dropping off your child, you can rent a stroller for free at the airport until it's time to board. If you ask at your departure point, you can rent one at your destination from the time you get off the plane until you collect your baggage.

What do you do when you get on a plane?

If you have children under the age of 2, they will be escorted onto the plane before other passengers. The benefits of priority boarding include being able to go to your seat slowly without rushing, and being able to organize your baggage calmly.
Keep the items you're likely to use on the plane close to you, and store everything else in the overhead bin or under the seat in front of you.

When carrying a baby, only adults should fasten their seat belts. Mom and dad should fasten their seat belts first, then hold them. When using a baby carrier, wear the baby carrier while wearing the seat belt.

What should I be careful about on board?

During takeoff and landing, there is a sudden increase in atmospheric pressure, which can cause your ears to feel stinging and painful. It can be cured by removing the ears by swallowing saliva, but babies cannot do this.
They may cry due to discomfort or pain, so instead of having their ears plucked out, give them milk to drink. Drink it right before takeoff. The key is to time your drink well so you don't drink it all while you're on the runway.

Also, since the cabin is dry, it's a good idea to keep your child hydrated and take care of their dry skin. It may feel chilly at times, so it may be a good idea to bring a jacket or swaddle.

When holding your baby on your side, be careful not to let your head protrude into the aisle. There is a risk that someone walking may run into it and cause unexpected injury.

What services can I receive on board?

There is a restroom on board with a diaper changing table, and disposable diapers are available for free use. You can also get hot water to make milk. We also provide toys and lend out picture books.

However, you can only get hot water after takeoff and after the seatbelt sign is turned off. Be sure to have something to drink before takeoff to prevent pressure changes. There are restrictions on bringing liquids onto the plane, but exceptions include baby milk, hot water for formula, and baby food. You can bring it in if it is checked at the baggage inspection area.

On international flights, in-flight meals such as baby food and infant food are provided according to age and age.

You can also rent a baby cot (bassinet) for use on the plane. This is especially recommended for long flights as it allows you to stretch out and sleep comfortably. There are a limited number of seats available, so it's best to make a reservation in advance.

What should I bring on board?

Things you're likely to need on the plane include things for breastfeeding and changing diapers, a change of clothes in case your clothes get soiled, and a plastic bag to put dirty items and trash in.

Another thing you should bring is a baby carrier.
If your baby spends time on mom and dad's lap, they won't have to wear a seat belt. If there is a big tremor, you can feel safe if you can hold your baby securely with a baby carrier, and if your baby gets restless on the plane, using a baby carrier to comfort him can reduce the burden on mom and dad.

Another thing that people often forget is their passport. Your baby will also need a passport for international flights, so don't forget to prepare one.
