Frontier operates out of Concourse A, one of the airport’s three primary concourses (A, B, and C). This concourse has become synonymous with the airline's budget-friendly approach and serves as the departure and arrival point for the majority of Frontier flights.

• RTD A Line Commuter Rail: Offers a direct connection from Union Station to DEN

• Ride-share services like Uber and Lyft

• Airport shuttles, rental cars, and taxis

• Private vehicles with long-term and short-term parking options

Once at DEN, head to the Jeppesen Terminal – Level 6 East Side, where Frontier Airlines’ check-in counters are located. From there, passengers proceed to Concourse A via either the bridge walkway or the underground train (AGTS).
