Frontier Airlines has a straightforward infant policy. Infants under the age of 2 can travel for free when seated on an adult's lap. However, if you prefer, you can purchase a separate seat for your infant, ensuring more comfort during the flight. Additionally, you're allowed to bring a stroller and car seat on the flight to make your journey with your little one as convenient as possible. Frontier infant policy is committed to ensuring a smooth and pleasant travel experience for families with infants.
