Why the frontier airlines denver terminal Is So Important
Denver International Airport is Frontier Airlines’ primary base of operations. Frontier, a low-cost airline headquartered in Denver, operates the bulk of its flights out of this airport, using it as a central launching point for domestic and international destinations. Because of its strategic location and sheer size, the plays a pivotal role in connecting travelers across North America and beyond.
With over 100 destinations served from Denver and flights departing nearly every hour, this terminal handles significant passenger traffic daily. Knowing how to navigate it properly can make all the difference in your airport experience.
Where Is the Terminal Located?
Frontier Airlines operates primarily from Concourse A at Denver International Airport. While other carriers also share this concourse, a large portion—especially the east end—is dedicated to Frontier.
You’ll begin your journey in the main Jeppesen Terminal (Level 6) where Frontier's check-in counters are located. From there, you can reach Concourse A in two ways:
The pedestrian bridge—offering scenic views and a quieter journey.
The underground train (people mover)—a faster ride, especially during bad weather or peak travel times.
Once you reach Concourse A, follow signs to the east end of the terminal. That’s where the Frontier-specific gates and amenities are located.
The New Ground Boarding Facility
One of the most notable developments at the addition of a 120,000-square-foot ground boarding facility. This modern area, located at the easternmost end of Concourse A, features 14 new gates designed exclusively for Frontier Airlines operations.
Rather than using traditional jet bridges, these gates employ ground boarding ramps that allow passengers to board and deplane via both the front and rear doors of the aircraft. While this setup might feel unconventional to some travelers, it dramatically reduces turnaround time, allowing Frontier to keep fares low and operations efficient.
Notably, this new facility includes:
Spacious, tech-enabled seating areas
Water bottle refill stations
Family restrooms and nursing rooms
Pet relief areas
Charging stations at every gate
Retail and food outlets geared toward travelers on the go

Frontier recommends passengers arrive at least two hours before a domestic flight and three hours before an international one. Check-in counters for Frontier are located on the east side of the Jeppesen Terminal, with ample signage to guide you.

At the counter – for passengers with checked baggage or special needs
Via self-service kiosks – fast and easy, ideal for carry-on travelers
Through the Frontier mobile app – check-in, seat selection, and boarding pass, all in one
Passengers who have pre-paid for bags and printed their boarding passes in advance will find the process even faster.
TSA Security and Moving to Concourse A
After check-in, passengers proceed to TSA security checkpoints located on Level 5. Depending on your gate assignment, you'll want to pass through the security line that connects directly to Concourse A, either by the pedestrian bridge or the train.
