About
Delta infant policy also allows families to bring essential baby-related items without extra charges. Parents can bring a diaper bag, stroller, and car seat, and strollers and car seats can be checked at the gate at no additional cost. Delta infant policy encourages parents to bring the car seat to the gate even if they plan to have their child sit on their lap, in case extra seats are available.
