Infants and children on board

We know that your family’s safety and comfort is important to you. That’s why we’d like you to review the boarding requirements for traveling with babies and children. 

Babies, children and teenagers may travel unaccompanied or with a responsible adult, depending on their age.

  • Babies and children between the age of 0 and 7 years must always travel with an adult over the age of 18.
  • Children between the age of 8 and 11 years must travel with an adult over the age of 18 or an emancipated teenager (if traveling with one of their parents). If the child is traveling in a different cabin, you must inform the crew of the seat where the child is sitting. A child can also travel alone by requesting our Unaccompanied Minor service.
  • Teenagers between the age of 12 and 17 years can travel unaccompanied. If you prefer, you may also contract the Unaccompanied Minor service.

If your trip includes flights with other companies, we recommend you check to see if they have additional requirements.
 

Documentation

On our international flights, all minors must travel with their valid identity document or passport and their family record book or birth certificate. If the minor is traveling with only one of their parents, they must travel with a notarized statement from the parent who isn’t traveling. If the minor is traveling alone, they must travel with a notarized statement from both parents. You can get more information about the statement required in the countries of departure and arrival from the corresponding authority.

If you’re traveling with a baby less than 7 days old, you need to get a medical certificate for you and your baby. Send us the document via the Contact Form at least 48 hours before your trip.

Seats and safety

For trips in the Economy cabin

You can share a seat with a baby by paying a percentage of the adult fare, plus taxes. If you prefer that the baby travel in its own seat, you must pay a child fare and meet the safety requirements.

Keep in mind that for flights within Chile (except Easter Island) and Brazil, you don’t have to pay a fare or taxes for babies, but they do need a ticket.

For trips in Premium Economy and Premium Business

You have to pay a full fare for babies (no discount) and they must also travel in their own safety-approved seat.

What are the safety requirements?

  • Babies traveling in their own seat, regardless of the cabin, have to sit in a certified chair for use on board, or an Aviation Child Safety Device (ACSD) for children that weigh between 10 and 20 kilos.
  • If a baby turns 2 on the day of travel, they’ll have to fly in their own seat. In this case, you can purchase their round trip ticket with a child fare or pay the baby fare on the outbound flight and the child fare on the inbound flight.
  • Each adult may travel with up to 2 babies by booking an additional seat for one of them and paying the child fare. 

Baggage and personal items

If you’re traveling with a baby, you can bring one personal item on board the airplane, such as a purse, backpack or bag. The item cannot exceed the maximum allowance of 45 x 35 x 20 cm (height, length, width) and a child restraint device (certified seat, booster seat) or a folding or detachable stroller.

Travel System strollers are considered as one item, which means you can travel on board with one or both parts (base and seat). If there is no space available in the cabin, we will check it for free. .

Remember that the infant fare does not include baggage, but if you have a Promo, Light, Plus or Top fare ticket, you can purchase it at a discount up to 6 hours before your flight through My Trips, by calling the Contact Center or directly at the airport.
