Travelling with Children—How to Book Children on Allegiant Flights

According to Allegiant, passengers who are less than 14 years old on the date of travel are considered children. Under-14-year-olds must be accompanied by a passenger who is 15 years or older and is travelling on the same flight reservation. Flight reservations can be made the normal way, i.e., by phone or online/mobile app.

There are 2 options to make a flight booking for children below 2 years of age:

  • As a lap infant on the accompanying adult’s seat, or 
  • As a ticketed passenger travelling on their own seat with an FAA-approved car seat 

If you’re booking online, you will be asked to choose your travel preference (above) when entering your child’s date of birth. If your child is travelling on his/her own seat, you must use an FAA-approved car seat. Also, be sure to bring your child’s birth certificate/age proof document.

Photo ID

Passengers under 18 years of age travelling alone must provide valid documentation to prove their age, such as a birth certificate or a government-issued photo ID. Otherwise, they may be denied boarding. 

Passengers not carrying a government-issued ID may have to go through additional screening procedures. 

Flight Delays and Cancellations Due to Weather Advisories

Allegiant does not allow children below the age of 18 to travel alone on any flight with a weather advisory, unless they are accompanied by an adult passenger on the same booking. If an unaccompanied minor is being denied travel due to a weather advisory, call Allegiant Customer Care for assistance. 

Seat Reservations for Children

If you don’t reserve your seats in advance, you may be separated from your group. To ensure that you don’t get separated from your group, be sure to book your seats in advance—either through Manage Travel or when checking in online or through the mobile app.

FAA safety regulations do not allow children to occupy exit row seats or more than 1 lap infant per row (to ensure availability of oxygen masks). Children using car seats must occupy window seats. They are not allowed to occupy aisle seats, seats between a passenger and the aisle, or seats in rows just behind or in front of an exit row.

Car Seats and Child Restraint Systems


What types of car seats and child restraint devices are acceptable on Allegiant? 

Per FAA recommendations, children and infants weighing less than 40lb should either use FAA-approved car seats or harness-type devices.

Approved car seats or child restraint systems must:

  • Have the FMVSS.213 insignia, and/or
  • Indicate that they are certified/approved for aircraft use, and/or 
  • Indicate that they comply with the federal motor vehicle safety standards

Note. Car seat-type child restraint systems that are more than 17.88in wide may not fit in all seats. The FAA does not allow the use of safety belt extensions (belly belts), backless booster seats, and harness devices/vests which can be attached to adults. 

The AmSafe Aviation CARES harness-type device is the only device which is approved by the FAA. It can be used by children who weight between 22 – 44lb, as long as it bears a label stating
FAA Approved in Accordance with 14CFR 21.305(d), Approved for Aircraft Use Only.

How to Check in a Car Seat

If your child will not be using his/her car seat on the flight, you can:

  • Check in the car seat as checked baggage and collect it at baggage claim, or 
  • Gate check the car seat in the boarding area and collect it at the gate area after reaching your destination

Allegiant does not charge ticketed passengers any fee for checking in or gate checking a car seat.

Strollers

Allegiant allows you to check in a stroller as either at the check-in counter or at the boarding gate. You will not be charged any fee for checking in or gate checking 1 stroller per ticketed passenger.  

Diaper Bags

Ticketed passengers travelling with children are allowed to carry 1 diaper bag per ticketed passenger free of charge. The diaper bag will not count as a carry-on bag or a personal carry-on item.
