What is the Priority Boarding for Families With Infants?
Priority boarding is a huge perk when traveling with an infant on LATAM Airlines in 2026 because it means you can skip the lines and settle in before the rush. LATAM includes families with children under two years old in their “Special Assistance” group, which is typically called right at the start of the whole boarding process. This gives you a lot of extra time to get your carry-on organized, make sure your seat area is ready, and help your baby feel calm and relaxed before the cabin gets crowded. You’ll be able to use this early boarding time to secure overhead bin space for your diaper bag and take a few minutes to get comfortable and calm before takeoff, instead of being rushed by the rest of the passengers.

Even with a digital boarding pass, you should plan to visit the physical check-in counter if you’re bringing along bulky gear like a stroller or car seat.
