Am I allowed to carry my infant on my lap during flight?

PRO TIP:  You must check in with an agent if you are traveling with an infant on your lap.  Please review the FAQ article "What time do I need to arrive at the airport for my flight?" for specific arrival guidelines for your airport.

  • From 7 days old until his/her second birthday (age 7 days to 23 months), a child is considered a lap child and does not need a paid seat; however, guests may opt to buy a seat for the infant if they prefer.
  • Per federal regulations, once a child has their second birthday (24 months and older), 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 old 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 old and is traveling with someone who is at least 15 years old, you are not required to purchase a seat for them and can carry them in your lap free of charge.


  • Only one lap child is allowed per guest 15 years of age or older.
  • An infant, age 7 days or less or an infant requiring an incubator or other life-support system, cannot be accepted for travel and will be denied boarding.
  • Lap children and children in car seats are not allowed to be in the emergency exit rows or in the row in front or behind the emergency exit row.
  • Lap children and children in car seats are not permitted to occupy a seat equipped with an inflatable seatbelt.
  • On some aircraft, lap children may not be seated in the first or second row.
  • Taxes and fees may apply for the infant, depending on destination.
  • You can add a lap child while booking online or through our other reservation channels.

If you plan to bring a child restraint seat, please review the requirements.
