Infant Age Restrictions

Infants and small children must be accompanied by someone who is at least 18 years old, or is the child's parent or legal guardian. The adult and the child must travel in the same cabin.

If you're traveling with a newborn, Delta and Delta Connection® Carrier flights do need an approval letter from a physician saying it's all right for the newborn to fly. The following infant age restrictions apply to all Delta and Connection Carrier flights:

   
Airline Infant Age Requirement or Restriction
Delta Less than 7 days Physician travel approval letter
Comair® Less than 12 days Physician travel approval letter
SkyWest® Less than 7 days Physician travel approval letter
