Delta Airlines offers a comprehensive and family-friendly approach when it comes to traveling with young children, and the Delta Airlines infant travel policy is designed to ensure a safe and comfortable journey for both parents and infants. According to the Delta Airlines infant travel policy, infants under the age of two may travel on the lap of an adult passenger without requiring a separate seat, although purchasing a seat and using an FAA-approved child restraint system is highly recommended for enhanced safety. The policy also allows for one infant per adult traveler, and any additional infants must occupy a separate seat with an appropriate child safety device. In terms of fares, the Delta Airlines infant travel policy specifies that while infants traveling on the lap domestically within the U.S. can do so at no cost, international travel may require the payment of taxes and fees, even if the infant does not occupy a separate seat. Parents traveling with infants can also take advantage of early boarding, allowing extra time to get settled.
