Domestic airports are facilities that handle flights within a single country. They serve as hubs for travelers to connect to various cities and regions without crossing international borders. These airports typically offer a range of services, including ticketing, baggage handling, and security checks. In the United States, for example, major domestic airports like Los Angeles International Airport and Chicago O'Hare provide numerous flight options for passengers. Domestic airports vary in size, from small regional airports to large international ones, but all focus on facilitating air travel within the nation.
