Washington Dulles International Airport Concourse CD Map (Most Up-To-Date)
Concourse C/D is a single long, straight airside spine with Concourse C flowing into Concourse D at the C30/D1 numbering flip, plus one major offset connector: the Concourse C AeroTrain station sits well south of the gates and connects via the PenFed-branded tunnel. Within the Dulles main-airport complex, the fastest “shape read” is simple: rail reaches C (via tunnel), but D depends on Mobile Lounges or a long walk.
Map Table
| Zone | Key landmark | Connection | Walk time |
|---|---|---|---|
| Concourse D core | D1/D3 rotunda, Mobile Lounge dock | Mobile Lounge ↔ Main Terminal | 0–2 min to D1 gates |
| C↔D interface | C30 / D1 numbering flip | airside corridor | 5–8 min to C18 area |
| Concourse C AeroTrain access | between C18, United Polaris Lounge | PenFed tunnel ↔ AeroTrain | 5–7 min to platform level |
| South offset station | Concourse C AeroTrain station | AeroTrain ↔ Main Terminal / A | station-to-gates via tunnel |
Washington Dulles International Airport (IAD) Concourse C/D Map Strategy
- Commit early: D-gates favor the post-security Mobile Lounge path; the AeroTrain-to-C option locks in the PenFed tunnel plus a long, no-moving-walkway walk to reach D.
- Use the C↔D “flip” as your north star: the true border is the C30/D1 numbering change, not a separate building or doorway.
- Navigate by anchors, not vibes: “AeroTrain” access is between Gate C18 and the United Polaris Lounge; the main D decision fork is the D1/D3 rotunda where “walk to Concourse C/AeroTrain” competes with “Mobile Lounge/Main Terminal.”
- Avoid impossible shortcuts: no AeroTrain station in Concourse D, no direct rail hop from Concourse C to Concourse B, and no faster airside path to the Main Terminal from D besides Mobile Lounges.

In 2025, Concourse C/D still runs as the “temporary-permanent” United-heavy linear concourse where the AeroTrain serves Concourse C indirectly through the PenFed tunnel, and Concourse D remains effectively rail-free. A current printable map matters most for spotting the C18/Polaris Lounge tunnel exit and the D1-area Mobile Lounge dock so you don’t accidentally commit to a slow, high-variability reroute.

What is the exact post-security Mobile Lounge boarding location for passengers going to Concourse D (doorway/zone name on the map)?
The post-security boarding point is the Main Terminal Mobile Lounge Dock signed for “Shuttle to D Gates” on the Departures/Ticketing Level. It sits in the airside departures-level circulation near the East Security exit area and is separate from the AeroTrain escalators down to the station level.
Use the map to stay on the post-security upper level after screening and follow “D Gates / Mobile Lounge” to the shuttle docks rather than “AeroTrain.” If you descend to the AeroTrain platform level, you’ve already passed the correct D-gates Mobile Lounge boarding zone and will be committed to the C-station + PenFed tunnel + long walk option.
Which Concourse D gate range is closest to the C↔D connector (shortest airside walk), based on the map?
The closest Concourse D gates are the low-number D gates clustered around D1–D4. The C↔D interface is the numbering flip where Gate C30 transitions directly into Gate D1 along the same continuous corridor.
| Reference point | Closest D gate range | Why it’s closest |
|---|---|---|
| C↔D interface | D1–D4 | immediately adjacent to C30/D1 junction |
| D concourse midpoint landmarks | D1/D3 area | same node as the border transition |
What is the exact walking distance (in feet/meters) from the C↔D connector to the Concourse C AeroTrain station entrance (airside)?
The walking distance is about 1,800–2,000 feet (roughly 550–610 meters) from the C↔D connector at C30/D1 to the Concourse C AeroTrain station entrance via the PenFed tunnel access point near C18. This total reflects the C30/D1-to-C18 corridor segment plus the PenFed tunnel run and its vertical circulation components before you reach the station threshold area.
| Segment | Approx. distance |
|---|---|
| C30/D1 to C18 area | ~1,000 ft (~305 m) |
| PenFed tunnel + vertical circulation to station access | ~760–1,000 ft (~230–305 m) |
| Total | ~1,800–2,000 ft (~550–610 m) |
What is the exact airside walking path (named corridors/landmarks) from Concourse D to the Concourse C AeroTrain station entrance without taking a Mobile Lounge?
The airside path runs from the D1/D3 rotunda through the main C/D corridor to the PenFed tunnel entrance between Gate C18 and the United Polaris Lounge. You stay entirely in the public secure concourse corridor and never enter the Mobile Lounge dock area.
From Concourse D, walk toward decreasing D gate numbers to the C↔D interface at Gate D1 where numbering flips to Gate C30. Continue straight in the same central corridor past the C20 gate area until you reach the signed AeroTrain access point at the PenFed-branded tunnel entrance located between Gate C18 and the United Polaris Lounge. Look for overhead signs reading “AeroTrain to Main Terminal / Concourse A/B.”
Where is the international-arrivals “Plane Mate” / people-mover loading point located (on-map corridor/turnoff) for reaching CBP/International Arrivals from C/D?
The international-arrivals Plane Mate loading point is not a public, walk-up dock in the C/D concourse; it’s accessed through the sterile international-arrivals corridor tied to the low C gates (C1–C14) or directly at the aircraft door. That means you cannot “walk to CBP” from Concourse C/D like a normal connection.
On the map, the usable locator is the segregated glass-walled sterile corridor system in the C1–C14 zone, which funnels arriving international passengers away from the main concourse to the Plane Mate interface for transport to the Main Terminal International Arrivals Building (CBP/FIS). In Concourse D, international deplaning typically routes straight into Plane Mate handling at the gate/aircraft position rather than a general concourse-side loading bay.
Where are the nearest restrooms to the Concourse D Mobile Lounge dock, and what is the shortest walking distance to them (airside)?
The nearest restrooms are the restrooms by Gate D1, immediately off the D1/D3 rotunda where the Mobile Lounge dock enters Concourse D. From the Mobile Lounge doors into the concourse, the walk is essentially a one-minute hop across the rotunda—about 100–200 feet (30–60 meters), depending on where your lounge parks in the dock position.
| Start point | Nearest restrooms | Shortest walk |
|---|---|---|
| Concourse D Mobile Lounge dock | near Gate D1 | ~100–200 ft (~30–60 m) |
Where is the vertical access point (escalator/elevator/stairs) between the Concourse C level and the AeroTrain platform at the C-station (exact map position)?
The vertical access point is at the PenFed tunnel/AeroTrain access node between Gate C18 and the United Polaris Lounge. This is the map-labeled transition where you leave the Concourse C corridor, enter the tunnel complex, and then take the long escalators/elevators down to the AeroTrain platform level.
Follow the “AeroTrain to Main Terminal / Concourse A/B” signs to the entrance between C18 and the Polaris Lounge; the escalator/elevator bank is immediately inside that access point as you drop from the concourse level into the connector-to-station stack.
What is the exact walking distance from the Concourse C AeroTrain station exit to the closest Concourse C gate corridor (gate cluster nearest the station)?
The walking distance is about 1,000 feet (roughly 305 meters) from the Concourse C AeroTrain station to the first Concourse C gate corridor at the C18 area. This includes the PenFed tunnel segment (about 760 feet) plus the added distance from vertical circulation and approach/exit corridors between the platform and the concourse-level emergence point.
| Start | End | Approx. distance |
|---|---|---|
| AeroTrain (Concourse C station) | Concourse C gates at C18 junction | ~1,000 ft (~305 m) |
On the map, what is the next AeroTrain station stop after Concourse C when riding toward Concourse B (single next-stop)?
There is no next stop toward Concourse B from Concourse C because Concourse C is not on a through line to B. The only train direction from Concourse C runs back along the loop toward Concourse A and the Main Terminal hub, and reaching Concourse B requires returning to the Main Terminal to switch lines.
Where on Concourse D are the “Walk to AeroTrain / Concourse C” wayfinding decision points (map-labeled junctions) that let passengers avoid boarding the Mobile Lounge by mistake?
The key decision point is the central rotunda node around Gates D1/D3 where Concourse D meets the Mobile Lounge dock and the corridor continues toward Concourse C. This is where map signage typically splits between “Mobile Lounge / Main Terminal” (to the dock) and “Walk to Concourse C / AeroTrain” (stay in the concourse corridor toward the C30/D1 numbering flip).
A second practical decision cue is the C↔D interface itself at the Gate D1 to Gate C30 transition: once you pass into the C-numbered gates, you’ve committed to the walking route toward the C18/Polaris Lounge PenFed tunnel entrance for AeroTrain access.
What is the exact walking distance from the Concourse D Mobile Lounge dock to the C↔D connector hallway entrance (airside)?
The walking distance is under about 200 feet (roughly 60 meters) because the Concourse D Mobile Lounge dock opens into the D1-area rotunda essentially adjacent to the C↔D interface. The connector hallway is the same continuous concourse corridor that immediately leads you past Gate D1 toward the Gate C30/D1 numbering flip.
| Start | End | Approx. distance |
|---|---|---|
| D Mobile Lounge dock (D1 rotunda entry) | C↔D interface corridor | <200 ft (<60 m) |
Where is the Mobile Lounge drop-off point in the Main Terminal relative to the escalators/elevators down to the AeroTrain platform (shortest mapped path)?
The Mobile Lounge drop-off is at the Main Terminal Shuttle Docks on the post-security Departures/Ticketing Level near the East Security egress zone. The AeroTrain escalators/elevators down are reached by staying on the same post-security level and walking inward toward the centrally located AeroTrain entrance before descending.
From the shuttle dock doors, follow overhead “AeroTrain” signs along the main post-security concourse spine to the bank of long escalators/elevators; you do not need to change levels until you reach the AeroTrain entrance, where you then descend to the platform.
