Delta Air Lines provides specific guidelines under its Delta infant policy to ensure a comfortable and safe travel experience for passengers traveling with infants. According to the Delta infant policy, infants under the age of two can travel either on the lap of an adult or in a separate seat with an approved child safety seat. Lap infants typically travel for free or at a reduced fare on domestic flights, while international flights may require a small fee or percentage of the adult ticket price. The policy also outlines regulations for carrying essential items such as diaper bags, strollers, and car seats, which can often be checked free of charge or brought as part of the carry-on allowance.
