For passengers flying through Denver International Airport (DEN) with Frontier Airlines, being well-informed about the frontier airlines denver terminal is essential.

But with its vast layout and multiple concourses, Denver International can be overwhelming without the right preparation.
Introduction to Denver International Airport (DEN)
Denver International Airport is one of the busiest and largest airports in the United States. Spanning over 33,000 acres, DEN serves as a central hub for domestic and international travel, with Frontier Airlines operating a significant portion of its flights from here. The airport's efficient design, modern amenities, and expansive layout make it a fitting home base for Frontier, which has established a strong presence in Denver over the past decade.
The airport comprises the Jeppesen Terminal and three concourses—A, B, and C—accessible via automated train or pedestrian bridge. Frontier Airlines primarily operates out of Concourse A, which is the main area of focus for this guide.
Frontier Airlines: A Low-Cost Carrier with High Reach
Frontier Airlines is a budget-friendly airline known for offering affordable fares and a pay-as-you-go service model. From its Denver hub, Frontier serves over 100 destinations across the U.S., Mexico, and the Caribbean. Its model allows passengers to customize their travel experience by choosing only the services they need—whether it’s checked baggage, seat selection, or in-flight refreshments.
Due to this structure, understanding how Frontier operates within DEN is especially important for travelers who want to avoid last-minute fees or confusion.
Getting to the frontier airlines denver terminal
Travelers can reach Denver International Airport via several convenient methods:
