Hartsfield-Jackson Atlanta International Airport is the largest airport in the US
Hartsfield-Jackson Atlanta International Airport (IATA: ATL) is the largest airport in the US. Located in Atlanta, Georgia, the airport covers 4,700 acres of land, which is equivalent to 7.3 square miles or 19 square kilometres.
The airport is named after former Atlanta mayors William B. Hartsfield and Maynard Jackson. It began as a five-year, rent-free lease on 287 acres of land that was once an abandoned auto racetrack called The Atlanta Speedway. The lease was signed on April 16, 1925, with the intention of developing the site into an airfield. The first flight into the then-named Candler Field landed on September 15, 1926.
Hartsfield-Jackson Atlanta International Airport has been the busiest airport in the world by passenger traffic since 1998, except in 2020 when travel restrictions due to the COVID-19 pandemic caused a dip in passenger numbers. In 2023, the airport recorded 775,818 arrivals and departures, serving about 105 million passengers and 734,771 tons of cargo. The airport has five parallel runways, three of which are 9,000 feet long, one is 10,000 feet long, and the longest measures 12,390 feet and can accommodate the Airbus A380.
In addition to its impressive size and traffic volume, Hartsfield-Jackson Atlanta International Airport is also known for its efficient operations. For example, the "end-around taxiway," Taxiway Victor, allows planes landing on the northernmost runway to taxi to the gate area without interfering with other aircraft taking off, resulting in significant fuel cost savings.

LAX serves as a hub for four legacy airlines
Hartsfield-Jackson Atlanta International Airport (ATL) is the largest airport in the United States, spanning 4,700 acres of land. It is also the busiest airport in the world by passenger traffic, serving around 55.4 million passengers annually. However, when it comes to the number of destinations offered, Dallas/Fort Worth International Airport (DFW) takes the lead with 260 destinations, despite serving fewer passengers.
Los Angeles International Airport, commonly known as LAX, is the fourth busiest airport in the country and the busiest international airport on the West Coast. It serves as a hub for four legacy airlines: Alaska Airlines, American Airlines, Delta Air Lines, and United Airlines. LAX offers flights to over 150 cities across six continents, making it a significant gateway to the Pacific region. Its chaotic atmosphere, characteristic of Los Angeles, surprisingly does not make travelling through LAX a miserable experience. In fact, it has been rated as one of the best large airports in the US by the Wall Street Journal.
LAX's ability to manage its high volume of traffic can be attributed to several factors. Firstly, the airport has implemented various measures to ensure a positive travel experience for its passengers. For instance, recognising the importance of hydration, LAX encourages the use of reusable water bottles as plastic water bottles are banned within the airport premises. This simple measure not only contributes to environmental sustainability but also ensures that travellers remain comfortably hydrated during their time at the airport.
Secondly, the efficient management of air traffic is a crucial aspect of LAX's success. The airport handles a significant number of aircraft movements, with Delta Air Lines operating from multiple gates within the complex. The presence of multiple terminals, including the Tom Bradley International Terminal, enhances the airport's capacity to manage both domestic and international flights effectively.
In conclusion, despite not being the largest in terms of acreage, LAX serves as a crucial aviation hub on the West Coast, connecting passengers to destinations worldwide. Its role as a hub for four major airlines underscores its significance in the US aviation landscape. Through a combination of efficient management, passenger-centric amenities, and effective air traffic control, LAX successfully navigates the challenges posed by its high volume of travellers.
