Frontier Airlines Infant Policy
Frontier Airlines allows infants under two years old to travel on an adult's lap without charge on domestic flights. Please review the Frontier Airlines Infant Policy, as a birth certificate may be required to verify the infant's age. Only one infant is permitted with one adult for safety purposes. A seat may also be purchased for the infant, and an FAA-approved automobile seat must be utilized. Infants are not eligible for carry-on baggage, but diaper bags are allowed.
