Navigating Denver International Airport (DEN) can feel overwhelming due to its massive layout, heavy foot traffic, and ongoing construction projects. Whether you're catching a tight connection or checking bags for the first time, understanding the core structure of the Jeppesen Terminal and its three detached concourses saves you from wasted steps and missed flights.
The primary search intent for travelers looking up a Denver airport gates map centers on figuring out how the central terminal connects to Concourses A, B, and C, locating security checkpoints, and finding specific gate numbers quickly. This guide breaks down the terminal layout, current concourse alignments, and practical strategies to move through DEN without stress.
Understanding the Jeppesen Terminal Layout
The iconic tented Jeppesen Terminal is the central hub of DEN, split into East and West sides based on your airline. The terminal is organized across several vertical levels, and knowing which floor you need prevents frustrating detours:
- Level 4: Passenger pick-up, baggage drop-off access, and hotel connections.
- Level 5: International arrivals, baggage claim, ground transportation, and temporary ticketing relocations due to ongoing terminal renovations.
- Level 6: Main airline check-in counters and access to the East and West security screening checkpoints.
Even-numbered terminal doors sit on the West side, while odd-numbered doors sit on the East side. Matching your drop-off door to your specific airline before arriving at Peña Boulevard keeps your journey smooth from the start.
Breaking Down the Concourses: Gates A, B, and C
Beyond security, DEN operates with three distinct concourses that are physically separated from the main terminal. You can't just walk out of security straight into a gate area; you have to travel underground or across a pedestrian bridge.
Concourse A
Concourse A features gates numbered A26 through A87. It handles many domestic departures alongside all international arrivals that lack border pre-clearance. You can reach Concourse A either by taking the underground train or by walking across the pedestrian skybridge directly from the Jeppesen Terminal. The skybridge features moving walkways and offers a clear view of the tarmac, making the walk straightforward if you prefer to avoid the train.
Concourse B
Concourse B is the primary hub for United Airlines and United Express, housing gates ranging from the lower B gates up into the high B80s. This concourse is exclusively accessible via the underground Automatic Guideway Transit System (AGTS) train from the main terminal or Concourse A. Allow extra time during peak morning hours, as Concourse B sees the heaviest volume of passenger traffic at DEN.
Concourse C
Concourse C features gates C23 through C67, primarily serving low-cost and domestic carriers like Southwest Airlines. Like Concourse B, Concourse C is only reachable via the underground airport train. The train ride from the main terminal takes roughly six to eight minutes, so factor this transit time into your gate-arrival calculations.
Navigating Airport Construction and Gate Changes
DEN is undergoing multi-year infrastructure expansions, which frequently shift ticket counter locations, security lanes, and gate configurations.
- Ticketing Relocations: Portions of Level 6 ticket counters are regularly updated or moved. Many non-United airlines temporarily shift ticketing desks to Level 5 during terminal renovations. Check your airline's app the morning of your flight to confirm your exact check-in zone.
- Active Construction Zones: Temporary walls, adjusted pedestrian pathways, and closed elevators appear across the terminal. Rely on the official DEN Interactive Map rather than outdated static PDFs to track real-time path changes.
- Last-Minute Gate Swaps: Regional flights often change gates shortly before boarding. Keep airport notifications turned on via your airline's mobile app to catch gate reassignments instantly.
For official updates on security wait times and parking availability, consult the Denver International Airport Official Site before heading to the airport.
Practical Strategies for Fast Transit
Moving through a busy hub like DEN requires a solid routine to avoid bottlenecks. Use these actionable habits to streamline your trip:
- Match your airline to the correct side: Check if your carrier operates out of Terminal East or Terminal West before your driver pulls up to Peña Boulevard. Dropping off on the wrong side forces a tedious walk across the terminal.
- Use security slot reservation programs: If available during your travel window, book a free time slot with DEN Reserve to bypass standard security queues.
- Choose the right transit method for Concourse A: If the security line or train lobby is congested, walk across the pedestrian bridge to Concourse A instead of waiting for the underground train.
- Buffer your connection times: If you're changing concourses, remember that you must ride the train back to the central underground station level and transfer to another concourse line. Give yourself at least 45 minutes for tight terminal-to-concourse connections.
Frequently Asked Questions
How do I get between Concourses A, B, and C?
The underground train system connects all three concourses and the main terminal. You simply exit your train at the desired concourse station, ride the escalator up to the gate level, and follow overhead signs. Alternatively, you can walk between the Jeppesen Terminal and Concourse A using the pedestrian bridge.
Where are the international arrivals processed?
International flights without pre-clearance land and clear customs at the Federal Inspection Station located inside Concourse A or the main Jeppesen Terminal Level 5, depending on the specific flight route. Follow airport signage immediately upon exiting the aircraft.
What should I do if my gate changes while I am on the train?
If your airline announces a gate change while you're mid-transit, exit the train at the next concourse platform, check the monitors near the station escalators, and board the reverse train if you need to head back to a different concourse.
Can I walk between Concourses B and C?
No, there are no pedestrian walkways connecting Concourse B to Concourse C or Concourse A. You must use the underground train system to travel between these concourses.
