Domestic airports are facilities that handle flights within a single country. They serve as hubs for airlines, allowing passengers to travel between cities without crossing international borders. These airports typically have shorter security lines and simpler customs processes compared to international airports. Most domestic airports offer various services, including ticketing, baggage claim, and food options. They are equipped with runways, terminals, and parking areas to accommodate travelers. Major airlines, such as American Airlines and Delta, operate numerous flights from these airports, connecting people to their destinations efficiently.
