How Much Does Parking at Dulles Airport (IAD) Cost?

IAD parking rates vary widely depending on how close you park to the terminal and whether you use an on-airport or off-site lot. Based on current rates from the Metropolitan Washington Airports Authority (MWAA) and verified off-site providers, here's the full picture (verified April 2026).

The on-airport Terminal Lot and Valet options are best for very short trips or travelers who prioritize proximity above all else. For anyone parking multiple days, the savings from off-site lots add up fast. A 7-day trip in the Economy Lot costs $105. That same trip at Comfort Suites Chantilly costs just $41.93 — a saving of over $63.

What Are the Cheapest Parking Options at IAD?

The cheapest parking at IAD comes from off-site hotel lots in the Herndon, Sterling, and Chantilly areas. All seven verified lots offer free cancellation and free shuttle service to the terminal.

Top 3 Cheapest Off-Site Lots at IAD

• Comfort Suites Chantilly - Dulles Airport — $5.99/day. The lowest verified rate near IAD. Uncovered self-park. On-demand shuttle runs 6:15 AM to 9:30 PM. Book early — this lot fills up during peak travel periods.
• Spark By Hilton Sterling Dulles Airport — $6.50/day. Just 8 minutes from the terminal. Hourly shuttle runs 6 AM to 10 PM. Good option if you need an early morning pickup.
• Hyatt House Dulles Airport — $6.95/day. Shuttle every 30 minutes from 6 AM to 11 PM. First-come, first-served on the shuttle. Arrive with extra time during busy periods.

Cheapest On-Airport Option

The IAD Economy Lot is the most affordable on-airport choice at $15/day. It holds 11,431 spaces — the largest single lot at Dulles. A free shuttle labeled "ECONOMY" runs 24/7 between the Economy Lot and Curb 2F at the Main Terminal. For more details on how the Economy Lot shuttle works, see our guide to Dulles Airport Economy Parking Bus.

Pre-booking the Economy Lot is available at reserve.flydulles.com for a guaranteed space and the lowest published rates.

How Does Off-Site Parking Compare to Official IAD Parking?

Off-site parking near IAD can cost 60% less per day than the on-airport garages. The main trade-off is a short shuttle ride — typically 5 to 12 minutes depending on the lot. Here's how the two options stack up.

On-Site vs. Off-Site Parking at IAD

• On-site (MWAA-operated): Rates from $15/day (Economy Lot). Direct pedestrian access via walkways and moving sidewalks. Operated by MWAA. ~21,500 total spaces.
• Off-site (hotel lots): Rates from $5.99/day. Free shuttle required (5–12 min ride). Operated by independent hotels. Security, lighting, and hours vary by property.
• Proximity: Garage 1 and Garage 2 connect directly to the terminal by underground walkway. Off-site lots add a shuttle step to your journey.
• Availability: On-site lots have large capacity, but can fill during Thanksgiving, July 4th, and spring break. Off-site lots are smaller — book ahead.
• Flexibility: All seven verified off-site lots offer free cancellation. MWAA pre-bookings also allow cancellation per their policy.
• Covered parking: The Dulles Airport Parking by Crowne Plaza offers a 75% covered parking deck at $9.95/day — the only covered off-site option in the verified data.

If you're flying internationally from Concourse A — which handles Air France, Lufthansa, British Airways, Emirates, and other carriers — Garage 2 connects directly via a covered pedestrian walkway and is noted as the most convenient on-site option for international departures. For a deep dive on that option, see the guide to Dulles Airport International Parking.

How Do IAD Parking Shuttles Work — and How Long Will You Wait?

Every verified off-site lot near IAD includes a free shuttle to the terminal. Wait times and operating hours vary, so check these details before you book — especially for early morning or late-night flights.

• Dulles Airport Parking by Crowne Plaza: 24/7 shuttle, every 30 minutes on the hour and half-hour. About a 6-minute ride to the terminal. The only off-site lot with around-the-clock service on a fixed schedule.
• Hyatt Regency Dulles Airport: Every 30 minutes from 6 AM to 11 PM. On-demand outside those hours. Closest off-site lot at just 5–8 minutes from the terminal.
• DoubleTree Washington Dulles Airport - Formerly Hilton: Every 30 minutes, 4 AM to midnight. Good for very early flights.
• Hyatt House Dulles Airport: Every 30 minutes, 6 AM to 11 PM. First-come, first-served. Arrives fuller during peak hours.
• Comfort Suites Chantilly: On-demand shuttle from 6:15 AM to 9:30 PM. Call ahead for pickup. Not suitable for overnight arrivals.
• Spark By Hilton Sterling: Hourly shuttle from 6 AM to 10 PM. Less frequent — factor in extra wait time.
• DoubleTree by Hilton Dulles Airport - Sterling: On-demand shuttle, 6 AM to 10 PM.

On-airport shuttle service is different. The free "ECONOMY" and "GARAGES" buses run 24/7 from Curb 2F at the Main Terminal. There's no published frequency for on-airport shuttles, but they run continuously throughout the day and night.

Tip: If your flight departs before 6 AM or arrives after 11 PM, your only off-site options with confirmed service are Crowne Plaza (24/7) and Hyatt Regency (on-demand overnight). Double-check shuttle hours before booking any off-site lot for early or late flights.

How Can You Save Money on IAD Airport Parking?

The biggest savings come from booking early and choosing off-site lots. Here are the most effective strategies, based on verified current rates.

1. Book off-site and save up to 62%. The cheapest verified off-site lot (Comfort Suites Chantilly at $5.99/day) costs 62% less than Garage 1 or 2 ($21/day). Over a 7-day trip, that's a saving of more than $105.
2. Use coupon codes on booking platforms. The Hyatt Regency Dulles lists at $7.85/day — but you can book it from $5.75/day via onestopparking.com or $5.95/day via book2park.com. That's among the lowest verified rates near IAD. The DoubleTree Washington Dulles (Formerly Hilton) also drops to $8.25/day via book2park.com.
3. Pre-book to lock in rates. Walking up to the Economy Lot costs the same as pre-booking, but pre-booking guarantees your space. For off-site lots, advance booking often unlocks lower rates. You can also explore options through the Dulles Airport Parking Promo Code guide for current deals.
4. Choose the Economy Lot for on-airport savings. At $15/day, it's the cheapest MWAA-operated option. The official Economy Lot page confirms the rate and shuttle details.
5. Avoid the Terminal Lot for multi-day trips. At $32/day, a week in the Terminal Lot costs $224. The same week in the Economy Lot is $105. For a 7-day trip, that difference is $119.
6. Check TSA PreCheck status. Getting through security faster with TSA PreCheck means you can arrive later — which gives you more flexibility to use a lot that's slightly farther from the terminal.

Is IAD Airport Parking Safe and Secure?

On-airport MWAA lots are fully secured and staffed. The 24-hour parking assistance line — 703-572-4500 — handles lost vehicles, flat tires, jump starts, and customer service around the clock.

Off-site hotel lots also maintain security, though features vary. Here's what each verified lot offers:

• Comfort Suites Chantilly: 24/7 security, handicapped accessible
• Spark By Hilton Sterling: Security on-site, handicapped accessible
• Hyatt House Dulles Airport: Handicapped accessible, hotel amenities on-site
• DoubleTree by Hilton Dulles Airport - Sterling: Security, handicapped accessible
• Hyatt Regency Dulles Airport: 24/7 security, fully handicapped accessible, restaurant, and fitness center on-site
• DoubleTree Washington Dulles Airport - Formerly Hilton: 24/7 security surveillance
• Dulles Airport Parking by Crowne Plaza: 75% covered deck, luggage assistance, security

All seven lots also offer free cancellation, so you're not locked in if plans change. For travelers with accessibility needs, every verified lot is handicapped accessible — a detail not always prominently listed on booking sites.

How Does IAD Parking Compare to Taking an Uber or the Silver Line Metro?

IAD sits 26 miles west of downtown Washington D.C. That distance makes the cost comparison between parking, rideshare, and transit more meaningful than at closer airports.

Rideshare (Uber/Lyft)

An Uber from D.C. or Northern Virginia to IAD can range from around $35 to $80+ depending on traffic, surge pricing, and pickup location. For a solo traveler on a short trip, rideshare may be cheaper than parking. For longer trips or groups, parking almost always wins on cost.

Silver Line Metro

The WMATA Silver Line connects IAD directly to downtown D.C. in about 53 minutes. This is a strong option for travelers flying solo without heavy luggage. Metro fares are set by WMATA and vary by distance — check WMATA's fare page for current pricing. The Silver Line station at IAD connects via the same underground tunnel as Garage 1, making it easy to combine parking with a Metro segment of your trip.

Parking

For travelers driving from suburban Northern Virginia — Herndon, Reston, Sterling, Ashburn, Chantilly, or Leesburg — parking near IAD is almost always the most practical and affordable choice, especially for trips of 3+ days. At $5.99 to $9.95/day for off-site lots, parking beats rideshare for nearly every multi-day trip.

Before you drive, it's worth checking the Waze live traffic map — the Dulles Access Road and Dulles Toll Road (VA-267) can slow significantly during rush hour, affecting how early you need to leave.

What Should You Know Before Booking IAD Airport Parking?

A few practical details can make a real difference on travel day. Here's what experienced IAD travelers check before confirming a reservation.

• Shuttle hours matter most. Not all off-site shuttles run overnight. If your flight departs before 6 AM, use Crowne Plaza (24/7) or Hyatt Regency (on-demand overnight).
• Factor in shuttle time. Add at least 20–30 minutes to your departure timeline for off-site lots. That includes driving to the lot, parking, waiting for the shuttle, and the 5–12 minute ride.
• Construction is active in 2026. IAD is mid-way through a $7 billion capital improvement program. Concourse E (14 new gates for United Airlines) is expected to open fall 2026. The D2 project begins October 2026 and will replace Concourses C and D. Some terminal areas may be busier than usual — arrive with time to spare.
• Pre-book for peak periods. Holiday travel, spring break, and summer weekends fill both on-airport lots and off-site lots faster than you'd expect. With ~21,500 on-airport spaces, IAD has real capacity — but popular lots still sell out. Book via reserve.flydulles.com for official lots, or compare all options on Triply.
• Free cancellation is standard. Every verified off-site lot in this guide offers free cancellation. Book ahead without risk.
• Need more booking details? See the full guide to Dulles Airport Parking Booking for step-by-step instructions on reserving a spot through official and third-party platforms.

Off-site hotel lots start at $5.99/day with free shuttles, free cancellation, and solid security. The Economy Lot at $15/day is the best on-airport budget pick.
