Find the Delta terminal at Denver Airport, its usual Concourse A gate area, how to reach it and why the assigned DEN gate can change.
Delta Air Lines uses Denver International Airport’s single Jeppesen Terminal for check-in and baggage services, while its flights normally arrive and depart from Concourse A. Delta is commonly assigned mid-numbered A gates, often around A24-A30, but the exact gate can change; always verify it on your boarding pass or airport display.
In our Aviation & Real-World Flying coverage, DEN is the passenger-facing IATA code and KDEN is the ICAO code used by pilots and aeronautical charts. Both identify Denver International Airport.
Is Delta in Terminal A or Concourse A at Denver?
Delta is in Concourse A, not a separate Terminal A. DEN has one landside passenger building, Jeppesen Terminal, connected to three airside concourses: A, B and C.
| Service | Delta location at DEN |
|---|---|
| Check-in and bag drop | Jeppesen Terminal, Level 6 |
| Departure and arrival gates | Concourse A, commonly around A24-A30 |
| Checked-baggage collection | Jeppesen Terminal, Level 4; check the display for the assigned carousel |
Passenger drop-off signs direct drivers towards the correct side of Jeppesen Terminal. Do not ask to be dropped at “Terminal A”: Concourse A is beyond security and cannot be reached directly from the road.
Which gates does Delta usually use at Denver Airport?
Delta flights are usually concentrated around the mid-numbered A gates, broadly the A24-A30 area. These are customary operating positions rather than a guaranteed set of gates.
Airport operations may move a flight because of aircraft size, late arrivals, maintenance, weather or another gate remaining occupied. Our explanation of how airline and aircraft gate assignments are made covers why the published gate can change even shortly before boarding.
- Refresh an old mobile boarding pass: a pass saved earlier may still show the original gate.
- Check the operating carrier: a Delta flight number operated by a partner follows that carrier’s check-in and gate arrangements.
- Verify arrivals separately: the gate used by an inbound Delta flight does not determine the gate for a connecting departure.
How do you reach Delta’s Concourse A gates?
After check-in, clear security in Jeppesen Terminal and follow signs for Concourse A.
- Check the gate first. Use the latest boarding pass or departure display rather than assuming the flight will use A26 or another familiar gate.
- Clear an open security checkpoint. Follow the airport’s posted routing because checkpoint arrangements and opening hours can change.
- Take the train to Concourse A. A is the first concourse stop from Jeppesen Terminal.
- Follow the A-gate numbers. Recheck a display after reaching the concourse in case the assignment changed while you were in transit.
Concourse A also has a pedestrian bridge connection from Jeppesen Terminal when the posted security routing permits it. For the pilot or simmer’s view of how the concourse sits among KDEN’s ramps and taxiways, use our KDEN approach plates and airport diagram; passenger displays remain the authority for the live gate assignment.
What should you do if Delta moves the flight to another concourse?
Follow the latest airport display even if it sends you away from Delta’s usual Concourse A area. DEN’s concourses are connected inside security by the underground train, so a move to B or C normally does not require leaving the secure area.
Allow time for the train and the walk to the new gate. A common mistake is staying near the original gate until boarding begins; once a concourse change appears on the display, start moving unless airline staff instruct otherwise.
Where do arriving Delta passengers collect bags?
Delta passengers collect checked baggage in Jeppesen Terminal on Level 4. Take the train from Concourse A to the terminal, then use the arrival screens to find the flight’s carousel because baggage belts are assigned separately from gates.
