Because airline child policies change — and parents shouldn’t have to hunt for answers.
Can you bring a car seat on a plane with Allegiant Air when traveling with a baby?
Car seat policy when flying Allegiant Air
Yes — you can bring and use a car seat on Allegiant Air provided the child has a purchased seat. The car seat must be FAA‑approved (look for the FAA approval label on the seat). If your baby is a lap infant (no purchased seat), they must ride on your lap and you cannot use the car seat for them unless you buy a ticket for the child.
- Seat requirement: The child must occupy their own, purchased seat to use a car seat onboard.
- FAA approval: Confirm the car seat has an FAA approval label — otherwise it is not permitted for aircraft use.
- Installation: Install the car seat using the airplane lap belt (or approved LATCH/seat‑belt installation per the car seat manual). Follow the car seat manufacturer’s instructions and orient as allowed by the seat (rear‑facing or forward‑facing).
- Gate check / carry-on: Many travelers gate‑check car seats or bring them onboard if they fit in the aircraft seat/overhead bin; check Allegiant’s current carry/checked item rules and fees before travel.
- At the airport: Measure the car seat to ensure it fits the aircraft seat, arrive early, and tell the gate agent you have a car seat so they can advise about boarding and checking options.
If you're unsure about model compatibility or fees, contact Allegiant customer service before your trip and keep the car seat manual handy for installation guidance.
