A Stress-Free Guide to Terminal/Concourse Hopping at Denver Airport

When it comes to seamlessly transferring between terminals, no major US airport does it better than Denver.

In fact, this is one of my favorite things about Denver Airport.

There are several reasons why someone would want to terminal hop at an airport:

• You’re connecting and need to switch terminals for your connection
• You want to check out a specific restaurant or coffee shop in another terminal
• You want to shop at a store in another terminal
• You have special Lounge access in another terminal
• You’re traveling in a group and want to meet up for a meal before going off to your separate terminals

Ever had to transfer terminals at LAX or Chicago O’Hare? If you have, I’m willing to bet that your first time was probably your last time – unless there was no other option.

You won’t feel this way if you have to switch terminals at Denver Airport. It’s the best when it comes to transferring between terminals.

There’s no exiting the airport. No re-entering through security. No buses or trains outside the airport. No 30+ minute walks. No major hassles.  There’s also moving walkways throughout the entire airport that make it faster to get from gate to gate.

Denver Airport Terminals

Denver Airport consists of one main terminal, named Jeppesen Terminal, and three concourses (or terminals) where you’ll find A, B, and C Gates.

What makes DEN unique is that all concourses are connected via an automated underground train system, eliminating the need for traditional above-ground shuttles or buses.

Important: Do not confuse Denver’s underground train system with the Denver Airport train.

Terminal Layout

The Jeppesen Terminal (often called the main terminal) is where you’ll find check-in counters, security checkpoints, and baggage claim. Everything starts or ends here.

From the main terminal, the concourses are arranged in alphabetical order from west to east:

• Concourse A: Frontier Airlines, JetBlue, Delta Airlines, United Airlines (limited gates) and international flights
• Concourse B: United Airlines
• Concourse C: Southwest Airlines and other domestic carriers (including American Airlines, Alaska Airlines)

One helpful feature to remember is that Concourse A is the only one connected to the main terminal by a pedestrian bridge, in addition to the train system. In other words, it’s the only Concourse that you can walk to from the main terminal.

The pedestrian bridge offers stunning views of the airfield and mountains, and it’s a great backup option if you’re heading to or from Concourse A. Just note that it will take you much longer than the tram.

In order to access Concourses B and C, you must take the underground train.

How to Use the Underground Train System

Denver Airport’s underground train system is located at the ground level in the center of each concourse.

Each train stop is accessed via escalators or elevators that go down to the ground level from the main level, which is where you’ll find gates and most restaurants.

There is one train platform and a train on each side going in opposite directions. There will be a sign above each side showing where that train is headed.

How to Ride the Train (Step-by-Step)

1. Look for the train icon on overhead signs throughout the airport
2. Follow signs to the nearest train platform (they’re clearly marked with black and white “TRAIN” signs)
3. Descend the escalator or elevator to the train level
4. Wait behind the yellow safety line on the platform
5. When the train arrives, wait for passengers to exit before boarding
6. Hold onto handrails (on the side and above) – the train accelerates quickly
7. Listen for automated announcements indicating the next stop
8. Exit when your concourse is announced

Important note: Trains run continuously in both directions and make the same stops in the same order. Pay attention to the signage to get on the train going in your direction.

How to Terminal Hop

1. Head to the train platform in your concourse
2. Check signage to see the train that you’ll need to board
   • If you’re in Terminal A, there will be one train going to Baggage Claim and another train going to B and C Gates
   • If you’re in Terminal B, there will be one train going to A Gates and Baggage Claim and another train going to C Gates
   • If you’re in Terminal C, there will be one train going to B, A Gates and Baggage Claim

Travel Times Between Terminals

Here are the estimated travel times between different points:

• Main Terminal to Concourse A: 2 minutes
• Main Terminal to Concourse B: 3 minutes
• Main Terminal to Concourse C: 4 minutes
• Between any two adjacent concourses: 2 minutes
• Full circuit (Terminal → C → Terminal): 8 minutes

Trains arrive every 2 minutes during peak hours and every 4 minutes during off-peak times, so you rarely have to wait long.

Accessibility and Special Needs

Denver Airport excels in accommodating passengers with mobility issues or special needs:

• All train platforms are equipped with elevators
• Level boarding means no steps between platform and train
• Priority seating areas are clearly marked on each train car
• Visual and audio announcements are provided for all stops
• Wheelchair assistance is available (request through your airline)
• Service animal relief areas are available in each concourse

For passengers using wheelchairs or mobility devices, the trains feature dedicated spaces with secure holding areas and extra handrails.

Backup Plans When Things Go Wrong

While the train system is highly reliable, it does break down occasionally, so it’s good to know your alternatives.

If the train system is temporarily down:

• Shuttle buses operate between all terminals as a backup
• The pedestrian bridge to Concourse A remains accessible
• Airport staff will be positioned throughout to provide directions
• Electronic signs will display current alternative routes
• Additional staff will be available to assist passengers with mobility needs

Emergency Contingency Tips:

• Always allow extra time for connections (minimum 45 minutes recommended)
• Save the airport’s information number in your phone: 303-342-2000
• Download the DEN airport app for real-time updates
• Look for airport ambassadors in white shirts for assistance
