A child over seven days old until their second birthday (younger than 24 months) is considered a lap child and does not need to pay for a seat; however, customers may opt to buy a seat for infant if they prefer.

As per federal regulations once a child has their second birthday (older than 24 months), they are no longer considered a lap child and a seat must be purchased in order for them to travel. If a child has their second birthday between the outbound and return flight, a seat will need to be purchased for the return flight.

Spirit reserves the right to request documented proof of age for any traveler 2 years of age or younger. Please be prepared to provide documentation (birth certificate, passport, etc) upon request.

As long as your infant is over 7 days old and under 2 years of age and is traveling with someone who is at least 15 years of age, you are not required to purchase a seat for them and can carry them in your lap free of charge.

Guidelines

Only one lap child is allowed per customer 15 years of age or older.
