Frontier Airlines allows infants from seven days old up to the child’s second birthday to fly free of charge in an adult’s lap.
An adult traveling with an infant in lap may carry a second personal item, such as a diaper bag, free of charge. Children older than two years old must have a purchased ticket and fly in their own seat. For added security, these children may sit in FAA approved car seats or harnesses. Booster seats can be used during the flight but not during takeoff and landing. For more information regarding traveling with children, please visit our website.
