Denver International Airport is one of the world's busiest airports
Denver International Airport (DEN) is one of the busiest airports in the world. In 2023, it was the sixth busiest airport in the world and the third busiest in the United States, serving around 77.8 million passengers, a 12% increase from 2022. In 2024, DEN set a new record, serving 82.3 million passengers, a further 5.8% increase.
Denver has traditionally been home to one of the busier airports in the United States due to its ideal mid-continent location for an airline hub. Several airlines, including United Airlines and Continental Airlines, had hubs at the former Stapleton International Airport, which helped make it the sixth-busiest airport in the country by the 1960s. However, Stapleton had limited capacity for expansion, which often led to long delays and nationwide travel disruptions in bad weather.
Denver International Airport has one terminal, the Jeppesen Terminal, named after aviation safety pioneer Elrey Borge Jeppesen, and three midfield concourses with a total of 169 gates. Concourse A can be accessed directly from the terminal building via a pedestrian bridge or the underground train system that services all three concourses. Passengers must use the train to access Concourses B and C. All international arrivals without border pre-clearance are processed in Concourse A, which also has four 3-jetway international gates that can support the two largest commercial aircraft in the world, the Airbus A380 and the Boeing 747-8.
DEN is the primary economic engine for the state of Colorado, generating over $36 billion for the region annually. The airport offers a range of amenities for travellers, including dining options, shopping, lounges, and self-care services. It is also known for its extensive public art collection, featuring four murals by Chicano artist Leo Tanguma, and Colorado-inspired rotating exhibitions. DEN provides free wireless internet access throughout the airport and a free cell phone waiting lot located approximately three miles west of the Jeppesen Terminal.

TSA PreCheck and CLEAR users experience shorter wait times
Denver International Airport is one of the busiest airports in the world, so it's important to plan your visit carefully. The airport recommends that passengers arrive at least two hours before boarding time. There are plenty of dining options, shops, lounges, and self-care services to enjoy after checking in. Free wireless internet is also available throughout the airport.
If you're looking to streamline your security screening process at Denver International Airport or any other airport, consider enrolling in TSA PreCheck or CLEAR. Both programs offer shorter wait times and a more efficient travel experience.
TSA PreCheck allows travelers to go through a dedicated lane with less rigorous screening protocols. About 99% of TSA PreCheck passengers wait less than 10 minutes. Children 17 and under can also join an adult with TSA PreCheck when it appears on the child's boarding pass. To enroll, simply follow three steps or walk into any enrollment location. The process includes fingerprinting, document and photo capture, and payment.
CLEAR uses biometric technology, such as fingerprint and iris recognition, to verify your identity quickly. This allows travelers to bypass traditional ID checks and move directly to a dedicated lane for screening. CLEAR members are paired with a CLEAR representative who assists them through security. While CLEAR can be used independently, combining it with TSA PreCheck can further reduce wait times. According to users, the combination of CLEAR and TSA PreCheck has resulted in wait times as low as two minutes during the morning rush.
By leveraging CLEAR's biometric technology for swift identification and TSA PreCheck's simplified screening process, travelers can significantly reduce their time spent in security lines, making their overall airport experience smoother and less stressful.

DEN provides free wireless internet access throughout the airport
Denver International Airport (DEN) provides free wireless internet access throughout the airport. This means that passengers can enjoy complimentary WiFi in all areas of the Jeppesen Terminal and across all three concourses.
There are two WiFi networks available: "DEN Airport Free WiFi" and "DEN Airport Free WiFi 2.4". The latter operates on the 2.4 GHz frequency, which may be preferable for certain devices or in areas with high network congestion. The average speed of the WiFi is around 61 Mbps, but this can vary depending on various factors, such as how many travellers are connected, how far you are from the main WiFi points, and the type of device you are using.
To connect to the WiFi, simply enable the WiFi connection on your device, open your device's WiFi settings, and select one of the two WiFi networks mentioned above. You will then need to accept the terms and conditions to gain unlimited access to the airport's WiFi.
While the WiFi is a great way to stay connected, check your flight status, or browse the internet while waiting for your flight, it is important to note that it is a free hotspot accessible to everyone. As such, it lacks the security provided by private WiFi hotspots. Therefore, it is recommended to avoid accessing personal or financial information while connected to the airport's WiFi. Instead, consider using a VPN, a prepaid SIM card, data roaming, or pocket WiFi for more sensitive activities.
