Denver Airport Delays: What's The Holdup?

Denver International Airport (DEN) is one of the busiest airports in the world, generating over $36 billion for the state of Colorado annually. With such a high volume of traffic, it is inevitable that some flights will experience delays. Several factors can contribute to flight delays at DEN, including weather conditions, construction, and air traffic congestion. Real-time status updates on the airport's website provide information on any current delays, which can help travellers stay informed about potential disruptions to their journeys.

Delays caused by weather conditions

Denver International Airport (DEN) is one of the busiest airports in the world, and delays are not uncommon. Weather conditions can significantly impact the timely departure and arrival of flights at this airport.

Adverse weather conditions such as heavy snowfall, strong winds, or reduced visibility due to fog or snow can cause flight delays and even cancellations at Denver Airport. Winter storms can disrupt airport operations, leading to gate hold and taxi delays. In such cases, the safety of passengers and staff takes precedence, and travellers can expect delays ranging from a few minutes to several hours or even days in extreme weather events.

Thunderstorms are another weather phenomenon that can cause flight delays at Denver Airport. While they are more common in the summer months, they can occur at any time of the year. Thunderstorms bring lightning, strong winds, and heavy rain, which can impact aircraft operations and cause delays as a safety precaution.

Even without extreme weather events, regular changes in atmospheric pressure and wind speed and direction can affect the takeoff and landing of aircraft. These weather conditions may cause shorter airborne delays for arriving flights as they approach the airport or minor gate hold and taxi delays for departing flights.

It is always advisable for travellers to stay updated on the weather forecast and check the airport's website or their airline's website for delay information before heading to Denver Airport. The Federal Aviation Administration (FAA) also provides a map of US airports, indicating those experiencing delays, which can be a helpful resource for travellers.

Delays caused by airport construction

Denver International Airport (DEN) is one of the busiest airports in the world, and construction projects are often underway to ensure it remains a primary economic engine for the state of Colorado. While construction is necessary for the airport's development and improvement, it can sometimes cause delays in flight operations.

One notable example of delays caused by airport construction at DEN is the Great Hall Project, which aimed to renovate the Jeppesen Terminal at a cost of $650 million. The project, undertaken by Great Hall Partners (GHP), encountered significant setbacks primarily due to the discovery of weaker-than-expected concrete in the terminal after construction had already started. This issue prompted GHP to file a compensation claim and request an extension, arguing that they had encountered different conditions than what was initially disclosed. However, DEN denied these claims, citing that GHP had "failed to account for its concurrent delay or meet the requirements to establish the occurrence of a relief event." The dispute between the airport and the developer caused a rift in their relationship and resulted in mediation over the budget and schedule of the project. The project's completion date was pushed back by at least three years, impacting investors and causing operational challenges within the terminal.

In addition to the Great Hall Project, other construction projects at DEN have also contributed to delays. For instance, construction activity near Jackson Gap and 75th Ave. has resulted in detours and impacted travel to and from the airport. While a temporary off-ramp has been put in place, drivers on Jackson Gap have been unable to travel westbound on E 75th Ave. to the Pikes Peak shuttle lot. Such construction projects can cause gate hold and taxi delays of up to 15 minutes for departing flights and airborne delays of up to 15 minutes for arriving flights.

It is important to note that while construction-related delays can be inconvenient, they are often necessary for the long-term improvement of airport facilities and services. Airport authorities strive to minimise the impact of construction on flight operations and passenger experience, implementing detours and temporary solutions to maintain efficiency as much as possible.

Delays caused by air traffic control

Denver International Airport (DEN) is one of the busiest airports in the world, and delays are not uncommon. While there are many factors that can contribute to flight delays at Denver Airport, air traffic control is certainly one of the key factors. Delays caused by air traffic control can have a significant impact on travel plans and the overall airport operations.

On a general level, air traffic control delays at Denver Airport can result in gate hold and taxi delays for departing flights and airborne delays for arriving flights. These delays can range from a few minutes to 15 minutes or less, depending on the specific situation and the volume of air traffic at the time. It's important for passengers to stay updated on the status of their flights, as these delays can change rapidly.

One notable instance of delays caused by air traffic control at Denver Airport occurred in May 2023. A ground stop was called on a Sunday morning due to a shortage of air traffic controllers, leading to cancellations and disruptions. According to aviation expert Carmen Reale, this issue could persist during the summer months, as the high demand for air travel may further strain the already limited number of air traffic controllers.

To manage the potential for delays, the Federal Aviation Administration (FAA) has implemented several strategies. These include optimising commercial airspace, activating additional high-altitude routes, and encouraging airlines to reduce their schedules to make the workload more manageable for air traffic controllers. The FAA also highlights the critical need for consistent funding to hire and train the required number of controllers to handle the complex airspace safely and efficiently.

Passengers travelling through Denver Airport are advised to take certain precautions to minimise the impact of potential delays. Signing up for airline alerts, arriving at the airport early, and regularly checking security wait times and parking availability can help travellers stay ahead of any unexpected delays caused by air traffic control or other factors.

Delays caused by detours

Denver International Airport (DEN) is one of the busiest airports in the world. While it is a major hub for travel, there are often delays. Delays can be caused by a variety of factors, including detours due to construction or road closures.

On January 3, 2025, the airport experienced general departure and arrival delays due to gate hold and taxi delays, lasting 15 minutes or less. While these delays were minimal, they could have been caused in part by the detour on the off-ramp from Pena Blvd to Jackson Gap. This construction activity may have impacted travel, causing detours and delays for those driving to the airport.

Similarly, on January 5, 2025, the airport again experienced general departure and arrival delays of 15 minutes or less. It is possible that these delays were also influenced by the ongoing construction and detours near the airport. Drivers on Jackson Gap were unable to travel westbound on 75th Ave to the Pikes Peak shuttle lot, which may have caused confusion and delays for passengers trying to reach the airport.

Detours can cause delays at Denver Airport, as they impact the timely flow of traffic to and from the airport. Passengers may find themselves stuck in traffic or taking longer routes to reach their gates, which can lead to gate hold and taxi delays. While the airport provides updates on general departure and arrival delays, it is essential for passengers to stay informed about potential detours and plan their routes accordingly to minimise the risk of missing their flights.

Delays caused by other airports

When considering the causes of flight delays at Denver International Airport (DEN), it is important to acknowledge the impact of delays originating from other airports. While DEN itself may experience efficient operations, the ripple effects of delays from across the aviation network can contribute to hold-ups at this airport.

One significant factor is the busy nature of DEN, which is one of the busiest airports in the world. This high volume of traffic means that even minor delays at other airports can have a cascading effect, leading to knock-on delays at DEN. For instance, if an aircraft destined for DEN is delayed at its departure airport, it may arrive late at DEN, causing subsequent departure delays for that aircraft from DEN to its next destination. This disruption can then propagate throughout the network.

Additionally, DEN serves as a hub for several major airlines, including United Airlines, Frontier Airlines, and Southwest Airlines. These airlines rely on DEN as a key connection point in their networks. Delays at other airports within these airlines' networks can impact the timely arrival and departure of flights at DEN. This is particularly notable during peak travel seasons or when there are unforeseen disruptions, such as adverse weather conditions or air traffic control issues at other airports.

It is also worth noting that DEN experiences a significant number of connecting flights and passenger transfers. Delays at the departure airports of these connecting flights can impact the overall punctuality of services at DEN. This is especially relevant when considering the potential for delays at major connecting hubs, which can have a more pronounced effect on DEN's operations.

To mitigate these delays, airlines and air traffic management organisations employ various strategies, including rescheduling flights, utilising alternative routes, and deploying reserve aircraft and crew. However, the complex nature of the global aviation network means that delays caused by other airports will likely continue to impact DEN to some extent.
