Frontier Lap Infant Policy
The Frontier lap infant policy lets parents and guardians travel with kids who are under 2 years old without needing to buy another seat. The baby sits on the adult’s lap during the flight. A lot of families choose this for short flights.
Important rules under the Frontier Airlines lap infant policy are:
- Frontier Airlines lets you take one lap infant for each grownup who is flying. The grownup must hold the child at all times on the plane.
- If a grownup brings more than one infant, you need to get a seat and pay for a ticket for the second child. The child must also sit in an approved car seat.
- When you fly with a lap infant, the grownup needs to sit in seats that give extra oxygen masks. This helps keep you safe if there is a change in the air inside the plane.
- You can not use seats with airbag seatbelts for a lap infant, as these seats are not made for child safety.
- If two grownups have two lap infants, they should not sit on the same side of the row. This is because each row only has a set number of oxygen masks.
- For safety, you can not hold a lap infant as you taxi, take off, or land unless you have the right seat for the child, even if the cabin crew tells you to.
