The airport is twice the size of the next biggest airport in the US

Denver International Airport (DEN) is a behemoth. At 33,531 acres (52.4 sq mi; 135.7 km2), it is twice the size of its closest US competitor, Dallas-Fort Worth International Airport (17,207 acres). DEN is the largest airport in the Western Hemisphere and the second-largest on Earth, only falling behind King Fahd International Airport.

The airport's sheer size is a result of its location and future-proofing. DEN is located 23-25 miles from Downtown Denver, and its distance from the city centre is due to noise concerns and the desire to avoid limitations on future expansion. With an elevation of 5,430 feet above sea level, the airport is also susceptible to hot and high conditions, which impact aircraft performance during take-off. As a result, DEN requires a longer runway than airports at lower altitudes. Runway 16R/34L, at 16,000 feet long, is the longest public-use runway in North America and the seventh-longest globally.

The airport's large size also enables it to accommodate a high volume of air traffic and provides ample room for future growth. DEN is a significant hub for United Airlines and the largest operating base for Frontier and Southwest Airlines. In 2023, it was the third busiest airport in the United States, serving around 77.8 million passengers. DEN has consistently ranked among the top 20 busiest airports in the world every year since 2000.

The airport's infrastructure reflects its magnitude. The Jeppesen Terminal, named after aviation safety pioneer Elrey Borge Jeppesen, boasts a distinctive peaked roof designed by Fentress Bradburn Architects, reminiscent of snow-capped mountains. A pedestrian bridge connects the terminal to Concourse A, offering travellers a unique experience as they walk above taxiing planes. The expansive layout of DEN not only facilitates efficient air traffic management but also incorporates aesthetic and functional considerations, solidifying its reputation as one of the most impressive aviation hubs in the world.

It is susceptible to hot and high conditions due to its elevation

Denver International Airport (DEN) is a major airport in the Western United States, serving metropolitan Denver, Colorado. It is the largest airport in the Western Hemisphere by land area, covering 33,531 acres (52.4 sq mi; 135.7 km2). DEN is located 23-25 miles (37-40 km) from Downtown Denver and is known for its unique design, resembling the snow-capped mountains of Colorado.

Due to its elevation of 5,280-5,430 feet (1,656 m) above sea level, the airport experiences "hot and high" conditions. This elevation is higher than the city of Denver, which sits at 5,280 feet. The high altitude can lead to a range of issues, including altitude sickness, breathlessness, and dehydration. The thinner air at higher altitudes contains approximately 4% less oxygen than at sea level, which can cause headache, fatigue, and disrupted sleep. These symptoms are more likely to affect individuals with underlying lung problems or those engaging in strenuous activity. However, the effects of elevation are typically mild and brief for most travellers passing through the airport.

The airport's elevation also has implications for aircraft operations. The reduced air density at higher altitudes requires longer runways for aircraft to achieve the necessary speed for takeoff and landing. As a result, DEN features the longest public-use runway in North America, Runway 16R/34L, which is 16,000 feet (3.03 mi; 4.88 km) in length. This extended runway is a necessary safety measure to ensure aircraft can safely take off and land, even under challenging weather conditions.

The elevation of the airport and the surrounding region is a significant consideration for aviation operations. Aircraft performance is influenced by the air density, and the reduced oxygen levels can impact engine efficiency and lift generation. Therefore, the high altitude of DEN presents unique challenges and requirements for aircraft operating at this airport.

Additionally, the airport's elevation contributes to the region's weather patterns and climate. The "high and dry" conditions can result in lower humidity and increased solar radiation, impacting aircraft performance and passenger comfort. Overall, the elevation of DEN presents a unique set of considerations for airport operations, aircraft performance, and passenger well-being.

The airport has plans to expand its runways from 6 to 12

Covering an area of 33,531 acres (52.4 sq mi; 135.7 km2), the Denver International Airport (DEN) is the largest airport in the Western Hemisphere by land area and the second-largest airport in the world. DEN currently has six runways, five of which are 12,000 feet long, while the sixth, brought into service in 2003, is 16,000 feet long and 200 feet wide. This makes it the longest public use runway in North America and the seventh-longest in the world.

DEN is a major hub for United Airlines and the largest operating base for Frontier Airlines and Southwest Airlines. With over 40,000 employees, it is the largest employer in Colorado. The airport has consistently ranked among the top 20 busiest airports in the world every year since 2000. In 2021 and 2022, it was the third busiest airport in the world. In 2023, it was the sixth busiest airport globally and the third busiest in the United States, serving around 77.8 million passengers. In 2024, DEN set a new all-time passenger record, serving 82,358,744 passengers.

DEN's large size is mainly due to future-proofing, and the airport currently has plans to expand its runways from six to twelve. The airport's elevation of 5,430 feet above mean sea level makes it susceptible to hot and high conditions, necessitating longer runways for aircraft to reach safe takeoff speeds. The additional runways will also allow for more efficient operations, with a maximum of four runways in use simultaneously.

To accommodate the expansion, DEN will need to acquire additional land, as the current site already spans a vast area, nearly twice the size of its closest US counterpart, Dallas-Fort Worth International Airport (DFW). The expansion will require significant planning and adherence to various laws and regulations regarding runway and taxiway construction. DEN's expansion plans are part of its ongoing efforts to enhance capacity and improve the overall airport experience for passengers and airlines.
