Denver International (DEN) Airport Guide

Layout

• Jeppesen Terminal — main check-in and security.
• Concourse A — international, Frontier, some United.

The underground train connects all three concourses to the terminal.

Getting there

• A-Line train to Union Station — 37 minutes.
• Lyft/Uber — 30–45 min from downtown.

Security and lounges

• Multiple TSA PreCheck checkpoints across the bridge security and concourse-level.
• United Club locations on B; Centurion in C; Capital One in A.

Weather

• Strong winter storms can close runways briefly; deicing is well practiced.
• Spring/summer thunderstorms drift through afternoons; convective NEXRAD overlays in FlightyFlow help.
