The United States has many large airports that are among the best in the world.

Among them, let me briefly introduce the five "busiest" hub airports based on the number of flights and passengers.

  1. Hartsfield-Jackson Atlanta International Airport (ATL)

    • One of the busiest airports in the world, serving tens of millions of passengers annually.

    • It is also a major hub for Delta Airlines and can be considered the center of travel and business in the southeastern United States.

  2. Dallas/Fort Worth International Airport (DFW)

    • A hub airport connecting the southern and midwestern United States, it is the home base for American Airlines.

    • Its vast area requires the use of shuttles or Skylink for transportation within the airport.

  3. Denver International Airport (DEN)

    • Geographically located almost in the center of the U.S., it serves as a transfer airport connecting the east and west.

    • Its unique 'tent-shaped' roof design is also one of the tourist attractions.

  4. Chicago O'Hare International Airport (ORD)

    • A key airport in the Midwest, it is a major hub for United Airlines and American Airlines.

    • With multiple terminals, transferring between them can take some time, so it's best to allow extra time in your schedule.

  5. Los Angeles International Airport (LAX)

    • A gateway airport representing the western United States, it has well-developed routes to Asia and South America.

    • While the airline terminals are spaced apart, which requires caution when moving, the California atmosphere near the airport adds to the experience.

These airports see a large number of domestic and international flights throughout the year, and the number of transfer passengers is also significant, leading to considerable waiting crowds.

Since check-in and security checks can take a long time, it is safer to arrive a bit earlier than your departure time. Additionally, as the transfer terminals at each airport are often complexly connected, reviewing the airport's website or app in advance to understand the layout will make your experience much more convenient.
