Spirit Infant Travel Guide: How to Add Your Baby to an Existing Reservation

Planning to fly with your baby on Spirit? Whether you’re booking a new trip or need to add an infant to an existing reservation, understanding Spirit’s infant travel policies is essential. This guide covers everything you need to know about traveling with a lap infant or purchasing a separate seat for your child.

Spirit Infant Travel Policy Overview

Spirit allows infants under two years old to travel as lap infants without requiring a separate ticket for domestic flights. However, for international flights, lap infants need a ticket, typically at a discounted fare. Parents also have the option to purchase a separate seat for added comfort and safety.

Key Infant Travel Policies:

Lap Infants (Under 2 Years Old): Free on domestic flights; discounted fare applies for international travel.

Seat Purchase Option: Parents can buy a separate seat and use an FAA-approved car seat.

Minimum Age Requirement: Infants must be at least 7 days old to fly.

Bassinets (SkyCots): Available on select international flights in premium cabins.

International Travel Requirement: Lap infants need a ticket, usually priced as a percentage of the adult fare.

How to Add an Infant to an Existing Spirit Booking

If you've already booked your flight and need to add your baby, here’s how:

1. Online via the Spirit Website

Log in to your Spirit account.

Go to “Manage Reservations.”

Select your flight and choose the option to add a lap infant.

Enter your child’s details and follow the prompts.

2. Call Spirit Customer Service

For international flights or if you can't add an infant online, call Spirit Reservations at +1-855-546-5048 (OTA):

Provide your booking reference and infant’s details.

A representative will confirm any fees and ticketing requirements.

3. At the Airport

If you haven’t added your infant before check-in, you can do so at the airport counter. Be sure to bring:

For domestic flights: A birth certificate (if proof of age is required).

For international flights: A valid passport for your baby.

Infants in First Class & Economy

Spirit allows lap infants in both First Class and Economy. However, bassinets (SkyCots) are only available in select premium cabins on long-haul international flights. If traveling in First Class or Business Class, your baby must sit on your lap or in an approved car seat.

Purchasing a Seat for an Infant

For extra comfort and safety, parents can purchase a separate seat for their infant. If choosing this option:

✔ The baby must be secured in an FAA-approved car seat.

✔ Standard baggage allowances apply.

✔ Infant fares may be discounted, depending on the route.
