How to add an infant to Spirit Airlines?

Traveling with a little one can feel like juggling toys in turbulence, but with Spirit Airlines’ infant-friendly approach, it’s smoother than you’d expect. This guide unpacks everything about the Spirit Airlines infant policy, lap infant guidelines, and how to add your baby to your booking, all with tips that make flying with your tiny travel buddy easier than ever.

Spirit Airlines Infant Policy: Who Qualifies and How It Works

Under the Spirit Airlines infant policy, a baby aged 7 days to 23 months qualifies as a lap child, meaning they can fly without a separate seat. 

Would you prefer your baby to have their own seat? No problem! Spirit allows parents to purchase an additional seat and use an FAA-approved car seat or safety harness onboard for extra comfort.

Infants under 7 days old or those requiring medical devices (such as incubators) can’t travel for safety reasons, one of many ways Spirit keeps flying families secure.

Spirit Airlines Lap Infant Policy: Carrying Your Baby During Flight

Wondering, “Am I allowed to carry my infant on my lap during the flight?” Absolutely! Spirit Airlines lap infant policy allows one lap child per guest (aged 15 or older). This is a perfect option for new parents who want their baby close and want to save on airfare.

Spirit Airlines Add Infant: Booking Made Easy

Adding your little traveler to your reservation is as simple as your baby’s lullaby routine. Here’s how you can do it:

• During Booking: Choose the option to “add a lap infant” when you’re reserving your seats online. Enter your baby’s name and birth date to confirm.
  
  
• After Booking: Already booked your flight? Visit My Trips on Spirit’s website, enter your confirmation code, and select “Add Infant.”
  
  
• Need Help? Spirit’s “Let’s Chat” feature and Guest Service Agents can assist you anytime online or at the airport counter.
  
  

Spirit ensures the Spirit Airlines add infant process takes just minutes, so you can focus on packing baby wipes instead of stressing over forms.

Spirit Airlines Child Policy: When Your Baby Becomes a Toddler

Once your child turns 2 years old, they’re no longer considered an infant under the Spirit Airlines child policy. That means they’ll need their own seat and a paid fare even if their birthday lands between your outbound and return flights.

Spirit takes this policy seriously to ensure safety and compliance with FAA regulations. Always be prepared to provide age documentation for toddlers, especially when flying round-trip.

Traveling with Baby Gear: What You Can Bring for Free

Spirit Airlines understands that flying with a baby means packing half your nursery, so they make baby gear easy to manage:

• Strollers & Car Seats: You can check one stroller and one car seat per child free of charge. Got twins? A double stroller is excellent, too.
  
  
• Onboard Car Seats: If you’ve bought your infant their own seat, you can bring an FAA-approved child seat or CARES harness onboard (just not in emergency exit rows).
  
  
• Diaper Bags: Parents flying with children under two can carry one diaper bag for free; it won’t count toward your personal item or carry-on allowance.
  
  

Children Flying Alone: Spirit’s Unaccompanied Minor Policy

Spirit Airlines allows unaccompanied minors to travel on direct domestic flights (including Puerto Rico and the U.S. Virgin Islands). International routes aren’t permitted for solo minors.

Spirit’s team takes extra care of these young travelers, offering snacks, beverages, and attentive support throughout the flight. Parents can relax knowing their child is in safe, reliable hands.

Conclusion

With Spirit Airlines, flying with your baby isn’t just possible, it’s practical, affordable, and thoughtfully designed for families. Understanding the Spirit Airlines infant policy, and learning how to add an infant to your trip means you can take off stress-free.
