Once inside the airport, Delta passengers will proceed to Concourse A, accessible through the Jeppesen Terminal. Travelers can reach Concourse A by walking across the pedestrian bridge from the main terminal or using the underground train system that connects all concourses.
The pedestrian bridge is not only convenient but also provides a unique view of airport operations and runways. For those with luggage or mobility concerns, the train remains the fastest and most efficient route to reach Concourse A, where Delta’s gates are located.
Delta offers multiple check-in options at DEN to accommodate a variety of traveler preferences. At the Jeppesen Terminal, passengers can check in using self-service kiosks or head to the staffed Delta counters for assistance with luggage and special services. Sky Priority lanes are available for Medallion members and passengers in premium cabins, ensuring expedited service.
Mobile check-in through the Delta app allows travelers to skip the ticket counter entirely, receiving digital boarding passes and updates directly on their smartphones. This technology-first approach reflects Delta’s broader commitment to digital innovation and efficient airport operations.
Security screening at DEN is handled by the Transportation Security Administration (TSA) and offers several lanes, including standard, TSA PreCheck, and CLEAR. Delta partners with both TSA PreCheck and CLEAR to help eligible travelers move through screening quickly and with less stress.
