Southwest Airlines operates out of Concourse C at Denver International Airport, commonly called DIA or DEN. While your departing or arriving gates are located in Concourse C, all ticketing, check-in, and baggage drop take place in the main Jeppesen Terminal. Knowing how to navigate between these zones prevents missing your flight, especially during peak travel hours.
Understanding the layout before you arrive saves valuable time. Denver International Airport features a single main terminal building connected via an underground automated train system to three separate concourses: A, B, and C. Because Southwest flights service Concourse C exclusively, passengers must factor in security wait times and train transit times before boarding.
Check-In and Baggage Drop Location
If you need to check bags or print a physical boarding pass, head directly to the Jeppesen Terminal on Level 6, East Side. Southwest ticket counters and self-service kiosks sit near the East side doors.
- Curbside Check-In: Available on Level 6 outside the main terminal doors if you are traveling light or checked in via the app and only need to drop bags.
- Bag Drop Cutoff: Checked luggage must be processed at least 45 minutes before domestic departures. Arriving two hours early ensures you won't feel rushed.
- Baggage Claim: When returning to Denver on a Southwest flight, your luggage arrives at the East Side baggage claim on Level 5 of the Jeppesen Terminal.
For official updates on security wait times and airport maps, consult the Denver International Airport Official Site before you leave for the airport.
Getting to Concourse C
After dropping your bags and clearing TSA security screening in the Jeppesen Terminal, you'll need to reach Concourse C.
- Follow the overhead airport signage pointing toward the underground train system.
- Board the Automated Guideway Transit System (AGTS) train, which runs beneath the tarmac.
- Ride the train to the third and final stop, which is Concourse C.
- Exit the train, ascend the escalators into the main concourse area, and locate your assigned departure gate on the digital monitors.
The train ride takes less than three minutes, but crowding during peak morning and holiday rushes can add ten to fifteen minutes to your terminal transit time.
Concourse C Amenities and Gate Layout
Concourse C hosts dozens of gates stretching from the low 30s through the high 50s. Southwest utilizes the vast majority of these gates.
While waiting to board, you'll find plenty of dining, shopping, and seating options throughout the concourse. Local Colorado craft breweries, fast-casual restaurants, and coffee shops line the central spine. Power outlets are available near many gate seating clusters, though high-traffic areas fill up quickly during afternoon bank delays.
Common Mistakes to Avoid at DIA
Flying out of Denver requires careful planning due to the airport's massive passenger volume. Travelers often make a few preventable errors:
- Heading to the wrong terminal side: Parking on the West side when flying Southwest means a long walk across the massive Jeppesen Terminal to reach the East check-in desks. Look for signs for Garage East or East Terminal drop-off.
- Underestimating security lines: TSA checkpoints at DEN can experience massive lines during early morning banking hours (5:00 AM to 8:00 AM). Always check live security wait times on the airport app before entering the queue.
- Forgetting the train ride: Don't mistake Concourse C for an adjacent walking pier. You must take the underground train, which means you cannot walk straight from security to your gate without boarding the transit system.

Frequently Asked Questions
Can I walk to Concourse C from the main terminal?
No, Concourse C is detached from the main Jeppesen Terminal. You must ride the underground train system after clearing security.
Where should my driver drop me off for Southwest?
Your driver should follow airport signs for Jeppesen Terminal East, Level 6 (Departures). This puts you right outside the Southwest ticketing lobby.
What should I do if my Southwest flight arrives at a different gate or concourse?
While Southwest primarily operates out of Concourse C, irregular operations, weather diversions, or gate congestion can occasionally cause aircraft to park at Concourse A or B. Always verify your arrival gate on the airport monitors or your mobile app before heading to baggage claim.
Is PreCheck available at the East security checkpoint?
Yes, TSA PreCheck lanes operate on both the East and West sides of the Jeppesen Terminal. Using the East checkpoint places you closest to the train escalators leading to Concourse C.
