Hartsfield-Jackson Atlanta International Airport is a hub for Delta Air Lines

Hartsfield-Jackson Atlanta International Airport (ATL) is the primary international airport serving Atlanta and its surrounding metropolitan area. It is named after former Atlanta mayors William B. Hartsfield and Maynard Jackson. The airport is located 10 miles (16 km) south of the Downtown Atlanta district. Since 1998, Hartsfield-Jackson has been the world's busiest airport by passenger traffic, excluding 2020 when travel restrictions due to the COVID-19 pandemic impacted passenger numbers.

The airport's history is closely linked to the development of Delta Air Lines. In 1925, Atlanta acquired a five-year, rent-free lease on an abandoned auto racetrack, which became the site of the future airport. In 1930, Delta Air Service (later known as Delta Air Lines) began operations at the airport, making Atlanta one of its chief hubs. Over the years, the airport has undergone significant expansion to accommodate growing passenger traffic, including the construction of new terminals and runways.

Hartsfield-Jackson Atlanta International Airport continues to invest in its infrastructure, with plans for $1 billion in upgrades and construction every year for the next decade. The airport is also undergoing a 20-year master plan that aims to increase its capacity to serve more than 120 million passengers by 2031. This includes the expansion of Concourse D, which is being widened and extended while remaining operational.

The Delta hub at Hartsfield-Jackson offers various amenities for travellers, including the Delta Sky Clubs. These exclusive lounges provide customers with meal offerings, premium beverages, and thoughtfully designed spaces. The airline also offers convenient connections to destinations worldwide, making Hartsfield-Jackson a "destination between destinations".

Atlanta's geographical location and climate make it well-suited to reach much of the US

Hartsfield-Jackson Atlanta International Airport has been named the busiest airport in the world, with approximately 104.7 million passengers travelling through its terminals in 2023. This represented an 11% increase from the previous year.

The airport's success is due in part to its geographical location and climate. Atlanta's mostly ice-free weather makes it well-suited to reach much of the Eastern and Midwestern American population.

The city's leaders have also played a significant role in the airport's development. In the 1920s, they made a bid on crucial airmail contracts for the airport. Former Mayor Maynard Jackson and others convinced federal authorities to reroute I-85 to make way for a new terminal.

In addition, Atlanta has invested heavily in the airport's infrastructure. In 2011, the city embarked on a 20-year master plan to enable the airport to serve more than 120 million passengers by 2031. The plan includes upgrades to increase capacity and enhance the customer experience through modernisation.

The airport's location and extensive routes make it a vital hub for global journeys, offering unmatched connectivity and global reach for travellers.

The airport has a large capacity, with 192 gates and 7 concourses

Hartsfield-Jackson Atlanta International Airport has retained its position as the world's busiest airport for several years. The airport's large capacity is a significant contributing factor to its high volume of passenger traffic. With 192 gates across 7 concourses, the airport can accommodate numerous aircraft and passengers simultaneously.

The 7 concourses at Hartsfield-Jackson Atlanta International Airport connect the 2 main terminals, namely the Domestic Terminal (Concourse T, A, B, C, D, and E) and the International Terminal (Concourse F). The Plane Train, an internal shuttle service, facilitates seamless travel between the terminals and concourses, enhancing the efficiency of passenger movement within the airport.

Each concourse serves as a hub for various domestic and international flights operated by over 23 airlines, including both local and international carriers. Notably, Delta Air Lines, which has its headquarters at the airport, utilises all concourses for its operations. The presence of multiple concourses and the efficient connectivity they provide contribute to the airport's ability to handle a large volume of flights and passengers.

The large number of gates available at the airport, totalling 192, is a critical aspect of its capacity. These gates enable the efficient handling of arriving and departing flights, ensuring a constant flow of aircraft movements. The availability of multiple gates helps to minimise delays and optimise the utilisation of the airport's infrastructure.

The ongoing expansion and development projects at Hartsfield-Jackson Atlanta International Airport further emphasise the importance of capacity in maintaining its status as the world's busiest airport. The airport is constantly adapting to accommodate increasing passenger numbers and improve the overall travel experience. For example, Concourse D is being widened and extended to provide additional space and gates, allowing the airport to handle even more flights and passengers in the future.

It has a long history, with the first airmail flight taking place in 1926

Hartsfield-Jackson Atlanta International Airport has a long history, with the airport's first airmail flight taking place in 1926. The airport was built on an abandoned racetrack site, with city leaders, including not-yet-Mayor William Hartsfield, making a bid on crucial airmail contracts for the fledgling airport.

In the 1920s, aviation business was limited to airmail. In 1926, the airport went online just in time for the first airmail plane to land from Miami. A 1926 Constitution article published ahead of the first flight encouraged: "Business men are urged to send as many letters as possible in the first load of airmail."

The airport's history is emblematic of Atlanta's signature "boosterism", aiming high without letting the odds get in the way. This attitude has been described as a "phoenix rising from the ashes".

As passenger air travel grew in the 20th century, so did Atlanta's airport. Atlanta benefited from its mostly ice-free weather, making it well-suited to reach much of the Eastern and Midwestern American population. By the 1950s, it was in "genuine competition" with Chicago for the busiest airport title.

In 1957, Atlanta first claimed the title of the world's busiest airport, albeit only between noon and 2 p.m. each day. The airport officially gained the title in 1998.
