Do babies need a birth certificate to fly Delta?

Yes, Delta Airlines allows travel as an infant if they are under two years old. However, kids can travel on international and domestic flights. When infants travel internationally then delta charges 10% of adult fares and can travel free on domestic flights. Additionally, if kids fly internationally, they must show the required documents such as birth certificates and passports.
