Navigating Denver International Airport can feel overwhelming if you don't know how the Jeppesen Terminal connects to its three massive satellite concourses. The secret to a stress-free connection is mastering the underground train system and understanding that the airport is split into a central main terminal and isolated boarding zones.
DEN consists of the massive Jeppesen Terminal (divided into East and West sides for baggage and ticketing) and three independent concourses: Concourse A, Concourse B, and Concourse C. Unlike airports with connected piers, you can't walk between these terminals. You must ride the underground train or take the pedestrian bridge to Concourse A, making a reliable Denver airport gate map essential before you land.
Jeppesen Terminal Layout and Security
The main Jeppesen Terminal is where your journey begins or ends. It's shaped like a massive tent with white fiberglass peaks.
- Level 5: Baggage claim and international arrivals.
- Level 6: Passenger drop-off, ticketing counters, and check-in kiosks.
- Security Checkpoints: Located on the north and south ends of Level 6, plus a security screening area on Level 5.
If you're flying out, you'll check in on Level 6, clear security, and then head down to the underground train level. You can check current checkpoint wait times directly via the Denver International Airport Official Site.
Decoding Concourses A, B, and C
Once you're past security, you leave the main Jeppesen Terminal entirely. The gate layout is split across three distinct concourses that run parallel to each other.
Concourse A
Concourse A is the closest to the main terminal. You can actually walk to Concourse A via an elevated pedestrian skybridge from the Jeppesen Terminal, which features a moving walkway and floor-to-ceiling windows showing parked aircraft. Alternatively, you can take the underground train. Concourse A handles a mix of domestic and international carriers, including United, Delta, and British Airways.
Concourse B
Concourse B is the largest concourse at DEN and serves as the primary hub for United Airlines. It spans a massive footprint with gates ranging from B1 to B95. Because of its size, if you arrive at one end and your connecting gate is at the other, you're in for a 15-minute power walk. Keep an eye on the moving walkways and gate monitors.
Concourse C
Concourse C sits furthest from the main terminal and primarily hosts Southwest Airlines and Alaska Airlines. Gates range from C1 to C49. To reach Concourse C, you must ride the underground train. It's the final stop on the inbound train route from the main terminal.
Mastering the Underground Train System
The underground automated underground train links the Jeppesen Terminal to Concourses A, B, and C. It runs 24/7, arrives every couple of minutes, and takes less than three minutes to travel from the main terminal to Concourse C.
- Heading Out: After clearing security, follow overhead signs down the escalators to the train platform in the center of the terminal.
- Boarding: Stand behind the yellow safety lines and let arriving passengers exit before you board. The automated voice will announce your current concourse.
- Returning: When you land at Denver and want to exit to baggage claim, board the train heading toward the Jeppesen Terminal / Main Terminal.
Don't panic if you miss your train stop; it loops continuously between the main terminal and Concourse C.
Common Mistakes to Avoid at DEN
Travelers frequently make a few avoidable errors that ruin their tight connections at Denver International Airport.
- Mistaking Baggage Claim Sides: The Jeppesen Terminal is split into East and West sides. If you tell your rideshare driver or pickup party to meet you at East Baggage Claim when you're actually at West, you'll face a long walk across the terminal. Check your baggage carousel assignment before heading down to Level 5.
- Ignoring Train Direction Signs: Make sure you're boarding the train in the right direction. Signs clearly indicate whether the train is heading toward the concourses or back to the main terminal.
- Underestimating Concourse Length: Concourse B is exceptionally long. If you have a 30-minute connection, don't stop for food at the first spot you see; check your gate distance first.
