Dulles Airport Parking Garage: Rates, Access & Tips

Back to Complete IAD Airport Parking Guide

Dulles Airport parking garages are covered, self-park structures located on the airport grounds at Washington Dulles International Airport (IAD), offering $7/hour with a $21/day maximum. There are two garages — Garage 1 and Garage 2 — both connected to the Main Terminal via underground pedestrian walkways. They sit between the cheapest Economy Lot ($15/day) and the most expensive Terminal Lot ($32/day), making them a popular middle-ground for most travelers.

• Daily rate: $21/day maximum for both Garage 1 and Garage 2 (verified April 2026)
• Hourly rate: $7/hour — same for both garages
• Total garage capacity: 8,235 spaces combined (Garage 1: 4,508 + Garage 2: 3,727)
• Terminal access: Underground pedestrian walkways connect both garages to the Main Terminal
• Pre-booking recommended: Reserve at reserve.flydulles.com for a guaranteed spot
• Off-airport savings: Hotel lots start at $5.99/day — up to 71% less than the garage daily rate

What Are the Dulles Airport Parking Garage Rates for 2026?

Both Garage 1 and Garage 2 charge $7 per hour, with a daily cap of $21 — per MWAA's official rate schedule (verified April 2026). That cap kicks in after your third hour, so short stays and multi-day trips both hit the same ceiling.

Here's how the full on-airport rate card stacks up:

For a 3-day trip, both garages cost $63 total. For a 7-day trip, that rises to $147. The Economy Lot would cost $105 for the same week — saving you $42 at the cost of a shuttle ride. For long trips, that gap grows fast.

Which Dulles Parking Option Is Best for Your Trip?

The garages make the most sense for short trips of 1–3 days, when the $21/day cap beats the hassle of a shuttle. For longer stays, the savings shift quickly toward the Economy Lot or off-airport lots.

Garage vs. Economy Lot vs. Off-Airport: A Quick Comparison

• Garage 1 or 2 ($21/day): Best for short trips. Covered parking, walkway to terminal, no shuttle needed. Easy for early flights or late returns.
• Economy Lot ($15/day): Best for trips of 4+ days. Free 24/7 shuttle from Curb 2F runs continuously. Learn more about the IAD Economy Lot including shuttle frequency and location details.
• Comfort Suites Chantilly ($5.99/day): Best for budget travelers. 12 minutes from IAD, on-demand shuttle runs 6:15 AM–9:30 PM. Not ideal for very early or very late flights.
• Hyatt Regency Dulles ($7.85/day): Best off-site option overall. 5–8 minutes from IAD, 24/7 shuttle. Book via onestopparking.com from $5.75/day.
• Dulles Airport Parking by Crowne Plaza ($9.95/day): Best covered off-site option. 75% covered deck, 24/7 shuttle every 30 minutes, EV charging available.

For a 5-day trip, Garage 1 or 2 costs $105. The Comfort Suites lot costs just $29.95 for the same five days — a saving of over $75. See our detailed breakdown of Garage 1 vs Garage 2 if you need help choosing between the two on-airport options.

How Do the Garages Connect to the Dulles Main Terminal?

Both garages connect to the Main Terminal through dedicated pedestrian walkways — no shuttle needed. The connection is direct, sheltered, and works around the clock.

• Garage 1: Underground pedestrian tunnel with moving sidewalks leads directly to the Main Terminal. The same tunnel connects to the Silver Line Metro station at IAD — useful if you're catching transit after parking.
• Garage 2: Covered pedestrian walkway to the terminal. MWAA notes this garage is particularly convenient for international departures — making it a strong pick for flights on Concourse A carriers like British Airways, Lufthansa, Emirates, and Qatar Airways.

The walk from either garage to the check-in counters is manageable with carry-on luggage. If you have heavy bags or mobility concerns, the moving sidewalks in Garage 1's tunnel are a real help. Note that all ticketing and baggage check happens at the Main Terminal regardless of your airline or concourse.

Once through security, you'll reach your gate via the airport's Mobile Lounges (for Concourses A and B) or the AeroTrain (for Concourses C and D, and the new Concourse E opening fall 2026). The AeroTrain is an automated people-mover inside the secure zone — you board it after clearing TSA security screening, not from the parking garage itself.

How Do You Reserve a Dulles Airport Parking Garage Spot in Advance?

Pre-booking your garage spot locks in your space and can save you from arriving to a full lot. MWAA strongly recommends advance reservations, especially during holidays and peak summer travel.

1. Go to reserve.flydulles.com — the official MWAA booking portal.
2. Enter your travel dates (arrival and departure).
3. Select Garage 1 or Garage 2 from the available options.
4. Review the rate and confirm your booking. You'll receive a confirmation with a barcode for gate entry.
5. On travel day, use the barcode or license plate to enter the garage — no ticket needed.

All major credit cards and cash are accepted at the exit lanes. Pre-paid reservations may offer a small rate advantage and guarantee availability. For 24-hour parking assistance — including lost vehicles, flat tires, or jump starts — call 703-572-4500.

If you'd rather compare the garages against off-site options before booking, browse all IAD parking rates on Triply to see current availability and pricing across all lots.

Where Is the Dulles Airport Parking Garage Located?

Both garages sit close to the Main Terminal on the airport grounds. They're accessible directly off the Dulles Access Road (free, airport-use only) — the most direct route from I-66 and the Dulles Toll Road (VA-267).

Follow signs for "Garages" as you approach the terminal complex. If you're coming from the Herndon or Reston area, take the Dulles Access Road east. From Sterling or Ashburn, approach via VA-28 (Sully Road) to the airport spur. The garages are clearly signed from all main airport entry points. Before you leave, check real-time traffic on Waze — IAD sits 26 miles west of D.C. and the Dulles Toll Road can back up significantly during rush hour.

Garage 2 is slightly closer to the international concourses, which is worth factoring in if you're flying on an airline in Concourse A. Garage 1 offers the Metro tunnel connection — handy if someone is dropping you off and using transit home.

What Are the Long-Term Parking Options at Dulles Airport?

For trips longer than 3–4 days, the garages become expensive fast. At $21/day, a 10-day trip runs $210 in Garage 1 or 2. The Economy Lot caps at $15/day — that same trip costs $150, saving you $60. Off-airport lots cut costs even further.

Here's how long-term costs compare across verified IAD options:

• Garage 1 or 2: $21/day — $147 for 7 days, $210 for 10 days
• Economy Lot: $15/day — $105 for 7 days, $150 for 10 days
• Hyatt House Dulles Airport: $6.95/day — $48.65 for 7 days, $69.50 for 10 days
• Spark By Hilton Sterling Dulles Airport: $6.50/day — $45.50 for 7 days, $65 for 10 days
• Comfort Suites Chantilly: $5.99/day — $41.93 for 7 days, $59.90 for 10 days

For a 10-day trip, the Comfort Suites lot saves you over $150 versus the garage. The trade-off is the shuttle — but shuttles at most hotel lots run every 30 minutes or on demand. For a deeper look at extended IAD parking strategies, see our Dulles Airport long-term parking guide.

Is There EV Charging Available in the Dulles Parking Garage?

EV charging stations are available at IAD, though availability inside the garages specifically is limited. MWAA operates electric vehicle charging stations at the airport — check the official EV charging page for current locations and availability before you arrive.

For off-airport options, the Dulles Airport Parking by Crowne Plaza lot ($9.95/day) offers EV charging in its 75% covered parking deck — one of the few off-site lots near IAD to include this amenity. The airport is also mid-way through a 100 MW solar power facility project (started 2023) with battery storage and electric bus charging equipment, signaling a broader push toward electrification on site.

If EV charging is essential for your trip, confirm availability at your chosen lot before booking. The Crowne Plaza deck is the most reliable off-site option with verified chargers. For on-airport charging, call 703-572-4500 to confirm current garage availability before you drive in.

Tips to Save Money on Dulles Airport Parking Garage Costs

Saving on IAD garage parking is straightforward once you know the levers. Here are the most effective strategies:

• Book in advance: Reserve at reserve.flydulles.com to lock in your spot — especially around holidays. Lots fill up during peak summer weeks and Thanksgiving.
• Choose Economy for trips over 3 days: At $15/day vs $21/day, you save $6/day. On a 7-day trip that's $42 back in your pocket.
• Compare off-airport hotel lots: Hotel lots from $5.99/day run reliable shuttles and offer free cancellation. A 7-day stay at Hyatt House ($6.95/day) costs just $48.65 vs $147 in the garage.
• Use coupon codes for hotel lots: The Hyatt Regency Dulles books from $5.75/day via onestopparking.com — that's a real saving over the $7.85/day standard rate.
• Avoid the Terminal Lot for multi-day parking: At $32/day, it's designed for short stops and pickups. The garages give you the same covered access for $11/day less.
• Check Dulles Airport parking availability before you leave home — especially during peak periods, garages fill earlier than expected.
• Consider TSA PreCheck if security times are a concern: TSA PreCheck speeds up your airport experience regardless of where you park — worth pairing with a well-placed garage spot for a smooth morning.

One more thing to flag: Concourse E is opening in fall 2026, adding 14 new gates for United Airlines. The D2 project replacing Concourses C and D starts October 2026. Minor construction congestion around the terminal is possible — give yourself a few extra minutes when driving in during this period.
