how old.does a puppy.need to be to board?
Age Minimums. Most airlines, both national and international, have a minimum age requirement for puppies to fly. In most cases, puppies need to be at least 8 weeks of age of age before they're allowed on a plane. Some airlines, like Delta, will not accept puppies under 10 weeks of age. Others, like JetBlue, don't have a minimum age requirement.
