How Much Does Dulles Airport Parking Cost? (2026 Rates by Lot)

On-airport parking at IAD starts at $7 per hour across most lots, with daily maximums that cap your cost after the first full day. Based on current rates published by MWAA (verified April 2026), here is what you will pay at each official lot.

The Economy Lot is the clear winner for cost. At $15/day, a five-day trip costs $75 total. The same trip in the Terminal Lot runs $160 — more than double. For travelers who don't mind a short shuttle ride, the savings add up fast. The Economy Lot holds 11,431 vehicles, making it the largest facility at IAD by a wide margin. All lots accept major credit cards and cash.

The hourly rate of $7/hour applies to the Terminal Lot, Garage 1, and Garage 2. Short trips under three hours cost the same across all three. The main difference is proximity to the terminal and the daily cap. If you're picking someone up or dropping off quickly, any of these three lots work equally well on an hourly basis.

What Are the Official IAD Parking Lot Options?

IAD has five official on-airport parking zones, each serving a different type of traveler. Together they hold roughly 21,500 vehicles across all facilities. Here's what makes each zone unique.

Valet Parking

Valet parking is the most hands-off option at IAD. You drive to the Main Terminal entrance, hand over your keys, and walk directly to check-in. No shuttle, no walking to a garage. The cost is $39/day, making it the most expensive on-airport option. It's best suited for short trips where convenience is worth the premium.

Terminal Lot

The Terminal Lot sits directly across from the Main Terminal building. It charges a daily maximum of $32 and connects to the terminal via an underground pedestrian walkway with two access points. This is the closest self-park option to check-in. For more detail, see our guide on Dulles Airport Terminal Lot rates and access tips.

Garage 1 and Garage 2

Garage 1 and Garage 2 are both capped at $21/day — the sweet spot between convenience and cost for most travelers. Garage 1 connects to the terminal via an underground walkway with moving sidewalks. That same tunnel connects directly to the Silver Line Metro station, which is useful if someone is meeting you without a car. Garage 2 uses a covered pedestrian walkway and is noted as the most convenient option for international travelers. For a side-by-side breakdown, read our article on whether Dulles Garage 1 or Garage 2 is the better choice.

Economy Lot

The Economy Lot offers the lowest on-airport rate at $15/day flat. A free shuttle bus runs 24/7 from Curb 2F — look for buses marked "ECONOMY." The lot is uncovered and large, so allow a few extra minutes to reach your car on return. It's the best value for trips of three or more days.

How Do You Get from the Dulles Parking Lots to Your Terminal?

Getting from your parking spot to the terminal depends on which lot you use. Each zone has a different access method, and some are significantly faster than others.

• Valet: Walk directly from the Main Terminal drop-off — no transit needed
• Terminal Lot: Underground pedestrian walkway; two entrance points, no shuttle required
• Garage 1: Underground walkway with moving sidewalks; also connects to Silver Line Metro
• Garage 2: Covered pedestrian walkway to terminal; recommended for international flights
• Economy Lot: Free shuttle bus from Curb 2F, 24/7; look for "ECONOMY" signs

For Economy Lot users, the shuttle runs around the clock. Add 10–15 minutes to your airport arrival time to account for the shuttle wait and ride. During peak travel periods — including summer, Thanksgiving, and winter holidays — shuttles can be busier. The on-airport parking assistance line is available 24 hours at 703-572-4500 for lost vehicles, flat tires, and jump starts.

IAD is currently mid-way through a $7 billion capital improvement plan. Concourse E is under construction and expected to open in fall 2026, adding 14 gates for United Airlines. Minor terminal congestion is possible near active work zones. Check the Dulles Next construction updates page for the latest impact on terminal access.

Is Off-Site Parking Near Dulles Airport Cheaper?

Off-site hotel parking near IAD is significantly cheaper than on-airport options. Based on current Triply rates, seven verified lots in Herndon, Chantilly, Sterling, and surrounding areas start at $5.99/day — saving you up to 61% compared to the Economy Lot and up to 85% compared to Valet. Every option listed includes a free shuttle to the terminal.

A few important notes about off-site shuttles: most are not 24/7. The Hyatt Regency comes closest, with scheduled service every 30 minutes from 6 AM to 11 PM and on-demand service overnight. The Crowne Plaza is the only fully 24/7 option among hotel lots. If you have an early morning or late-night flight, verify shuttle hours before booking. The Comfort Suites shuttle, for example, stops at 9:30 PM — a real problem for late arrivals.

Some lots also have coupon pricing through third-party booking platforms. The Hyatt Regency drops to $5.75/day via onestopparking.com and $5.95/day via book2park.com. The DoubleTree Formerly Hilton starts at $8.25/day via book2park.com. These are among the lowest verified IAD parking rates available anywhere.

How Can You Save Money on Dulles International Airport Parking Cost?

There are several reliable strategies to reduce your IAD parking bill. None require special memberships or hard-to-find deals.

1. Book off-site hotel lots: Rates start at $5.99/day vs $15/day on-airport — a saving of up to $9/day or $63 on a week-long trip.
2. Use coupon platforms: Book the Hyatt Regency through onestopparking.com from $5.75/day — cheaper than any on-airport option by a wide margin.
3. Pre-book online: Reserve at reserve.flydulles.com to lock in the lowest on-airport rates and guarantee your space.
4. Choose Economy over Garage: Saving $6/day vs Garage 1 adds up to $42 on a seven-day trip — just add 10 minutes for the shuttle.
5. Avoid the Terminal Lot for multi-day trips: At $32/day, a seven-day stay costs $224. The Economy Lot costs $105 for the same period — a $119 difference.
6. Compare before you book: Prices vary by date and availability. Search IAD parking options on Triply to see real-time rates across on-site and off-site lots.

Timing matters too. IAD parking lots fill up fast around major holidays. Thanksgiving and Christmas are the busiest periods of the year. Pre-booking 2–3 weeks ahead during peak seasons helps you avoid paying walk-up rates or finding lots full on arrival.

Should You Park at Dulles or Take the Silver Line Metro?

The WMATA Silver Line now serves Washington Dulles International Airport directly, with a dedicated station at the airport. The Metro ride from downtown D.C. takes approximately 53 minutes. For solo travelers without heavy luggage, this can be more cost-effective than parking for multi-day trips.

Here's a quick cost comparison for a five-day trip:

• Economy Lot (on-airport): $75 total ($15 x 5 days)
• Garage 1 or 2 (on-airport): $105 total ($21 x 5 days)
• Comfort Suites Chantilly (off-site): ~$30 total ($5.99 x 5 days)
• Silver Line Metro (round trip from downtown D.C.): Fares vary by origin station — check WMATA's fare calculator for exact pricing

Parking makes the most sense if you live in Northern Virginia suburbs near Herndon, Reston, Sterling, Ashburn, or Chantilly — where driving to IAD is faster and more direct than connecting to the Metro. The Metro is a better fit for travelers coming from inside the Beltway or from Tysons Corner, Vienna, or Fairfax. The Silver Line station connects to Garage 1 via the same underground tunnel, so Metro and parking aren't mutually exclusive — some travelers park at a suburban Metro station and ride in.

Before you drive, it's worth checking real-time traffic on Waze, especially if you're traveling during rush hour on the Dulles Toll Road (VA-267) or the Dulles Access Road. Travel times to IAD range from 35 to 75 minutes depending on traffic conditions.

How Do You Reserve Dulles Airport Parking in Advance?

Pre-booking your IAD parking space is the smartest move for busy travel dates. It takes about two minutes and guarantees your spot — you won't arrive to a full lot.

For a full walkthrough of the reservation process and what to expect on arrival, the Dulles Airport parking booking guide covers every step in detail.

One practical tip: if you're flying United Airlines from Concourse C or D, Garage 2 is the most convenient on-airport option due to its covered walkway access. International travelers on Concourse A (Air France, Lufthansa, British Airways, Emirates, and others) will also find Garage 2 a smooth walk. Concourse E is expected to open in fall 2026 — once it does, gate access patterns may shift slightly. Review the official IAD parking information page for any updates closer to your travel date.

Making sure you know your TSA security screening requirements ahead of time also helps with overall travel planning. Paired with a pre-booked parking spot, it removes most of the stress from departure day.
