America is home to many international airports, from John F. Kennedy in New York City to Hartsfield-Jackson in Atlanta, Georgia. These airports serve as main hubs for big carriers such as United, American, Delta, and JetBlue. Although they can get busy (especially during holidays and peak seasons), the bigger airports tend to have the most direct international and domestic flight routes, which make it faster and more convenient to travel. Plus, they're usually more affordable compared to flying through small regional airports—meaning they're more than worth braving the crowds.
