How much baggage is allowed on Latam with a baby?

Babies (under 2) on your lap get an extra small bag (max 45×35×20 cm) free of charge. You can also take with you one stroller, bassinet, or certified car seat onboard at no cost. More than that, the Latam Airlines Infant Baggage Policy states that if cabin space is limited, those items go in the hold for free. However, if you buy a seat for your baby, normal baggage rules apply based on fare.

What is the travel policy for Latam Airlines infants?

If you are deciding to fly with your baby on Latam Airlines, you should know their travel policy to avoid any inconvenience during booking or while flying. The Latam Infant Policy covers all things from what ages a baby can fly on the plane to what is needed for them. That is why you should have a look at them from the bottom.

• Your newborn must be a maximum of 7 days old to fly. If younger, a doctor's note is needed.

• Babies under 2 years old can sit on your lap or in their own seat with a baby car seat.

• Travel is free for lap infants on domestic flights. On international flights, you pay 10% of the adult fare + taxes.

Are babies under 2 free on Latam Airlines?

Yes, babies under two can fly free with Latam Airlines, but it still highly depends on the routes you are flying on. Therefore, on domestic flights, babies flying on your lap are free; however, in Peru, you need to add a ticket for infants, and it will be at no cost. In contrast, on international flights, you pay around 10% of the adult fare, excluding Mexico.
