Parking at IAD Airport Cost: Every Rate Compared 2026

Back to Dulles Airport Parking Rates | Complete IAD Airport Parking Guide

Parking at IAD airport cost ranges from $20/day at the Economy Lot to $45/day for curbside valet on-airport, but the Hyatt Regency Dulles Airport off-site lot on Triply runs about $10/day, making it the clear winner for trips of four days or more. Washington Dulles International Airport offers five official parking options managed by the Metropolitan Washington Airports Authority (MWAA), plus two off-site lots in Herndon that Triply sells. On-airport lots connect to the Main Terminal by free shuttle, walkway or valet drop-off, and both off-site lots run a complimentary shuttle. On-airport rates are drive-up rates checked on flydulles.com in October 2026. Off-site rates are for a 7-day stay booked ahead and change by date.

• Economy Lot: $20/day, the cheapest on-airport option, free 24/7 shuttle from Curb 2F
• Garages 1 & 2: $25/day, walkway access to the terminal, best balance of price and convenience
• Terminal Lot: $40/day, closest self-park, underground walkway with two access points
• Valet: $39/day at the Service Center or $45/day curbside, no shuttle needed
• Hyatt Regency Dulles Airport (off-site, on Triply): about $10/day, about 52% less than the Economy Lot and 62% less than the garages, complimentary shuttle, 4-day minimum booking
• DoubleTree Washington Dulles Airport (off-site, on Triply): about $26/day, more than the Economy Lot and the garages, complimentary shuttle for online bookings
• Reserving at reserve.flydulles.com guarantees a space and gets the airport's lowest rates

What Are the Official IAD Parking Lots and Their Rates?

IAD has four distinct on-airport parking zones, each priced by how close you park to the terminal. All lots accept major credit cards and cash. Based on the airport's drive-up rates (checked on flydulles.com in October 2026), here's the full breakdown:

The on-airport lots hold roughly 21,500 vehicles total — the Economy Lot alone fits 11,431 cars, making it the largest facility by far. Garage 1 holds 4,508 vehicles, Garage 2 holds 3,727, and the Terminal Lot holds 1,852. For parking assistance, MWAA's 24-hour line is 703-572-4500 (covers lost vehicles, flat tires, and jump starts).

How Does Short-Term vs. Long-Term Parking at IAD Compare in Price?

For short stays under three hours, the Terminal Lot and Garages 1 and 2 are the most cost-effective on-airport choices, at $7 per hour. Valet is a flat $39 or $45 for day 1. For anything longer than one full day, the math shifts quickly toward the Economy Lot or, for trips of four days or more, the Hyatt Regency off-site lot.

Short-Term Parking (Under 24 Hours)

• Valet: Premium but fast. Day 1 is a flat $39 at the Service Center or $45 curbside, then $10/hr from day 2 up to that day's maximum.
• Terminal Lot: Great for 2 to 4 hours. At $7/hr capped at $40/day, it's the closest self-park option.
• Garages 1 & 2: Same $7/hr rate but cap out at $25/day, saving $15/day vs. the Terminal Lot for overnight stays.

Long-Term Parking (Multiple Days)

• Economy Lot: At $20/day flat, a 7-day trip costs $140. No hourly rate, daily flat fee only.
• Garage 1 or 2: At $25/day, a 7-day trip costs $175, and you get a walkway to the terminal instead of a shuttle.
• Hyatt Regency Dulles Airport (off-site, on Triply): At about $10/day, a 7-day trip costs about $67, roughly 52% less than the Economy Lot. It has a 4-day minimum booking.
• DoubleTree Washington Dulles Airport (off-site, on Triply): At about $26/day, a 7-day trip costs about $183, which is more than the Economy Lot ($140) and the garages ($175).

What Off-Site Parking Options Are Near IAD — And Are They Worth It?

Off-site parking near Dulles can be worth it, but only one of the two lots Triply sells undercuts the airport. Both are in Herndon, listed 1.9 and 2.1 miles from IAD, and both run a complimentary shuttle. The Hyatt Regency Dulles Airport is about $10/day, roughly 52% less than the $20/day Economy Lot and 62% less than the $25/day garages. The DoubleTree Washington Dulles Airport is about $26/day, which costs more than both.

The Hyatt Regency Dulles Airport stands out for early or late flights: its complimentary shuttle runs 24/7, every 30 minutes from 6 AM to 11 PM and on demand overnight. Check in at the front desk before you park, and note the 4-day minimum booking. The DoubleTree Washington Dulles Airport is parking only (no hotel stay needed) and takes full-size vans, pickup trucks and large SUVs at no extra charge, but it costs more than the Economy Lot and the garages, and there is no shuttle from midnight to 4 AM. Choose it for the vehicle allowance or the shuttle, not for price.

Important: Check shuttle hours before booking if your flight departs very early or lands late. The Hyatt Regency shuttle runs on demand from 11 PM to 6 AM, but the DoubleTree Washington Dulles shuttle does not run from midnight to 4 AM. Missing a shuttle can mean an expensive taxi.

How Do You Get From IAD Parking to the Terminal?

Getting from your parking spot to the Main Terminal depends on which lot you use. IAD offers three distinct connection methods, all managed by MWAA.

Underground Walkway (Garages 1 & 2, Terminal Lot)

Garage 1 connects via an underground pedestrian tunnel with moving sidewalks — the same tunnel links to the Silver Line Metro station. Garage 2 uses a covered pedestrian walkway and is particularly convenient for Concourse A international flights. The Terminal Lot has two underground walkway access points directly across from the building.

Free Shuttle (Economy Lot)

The Economy Lot uses a free 24/7 bus service. Catch it at Curb 2F — look for buses marked 'ECONOMY' or 'GARAGES'. The shuttle runs around the clock, so it works even for red-eye flights. Budget a few extra minutes during peak travel periods.

Valet Drop-Off

Valet parking at IAD means you hand over your keys and skip the shuttle. Curbside drop-off (Departures Zone 3, 4 AM to 10 PM) is $45/day. Service Center drop-off in the Terminal Lot (24 hours) is $39/day. All pickups are at the Valet Service Center.

Once inside, United Airlines flights depart from Concourses C and D (and soon Concourse E, opening fall 2026 as part of a $500M+ expansion). All other airlines use the Main Terminal for ticketing and bag check before heading to their respective concourse.

Is It Cheaper to Park at Dulles or Take an Uber/Lyft?

The break-even point for parking vs. rideshare at IAD is roughly a 2–3 day trip, depending on where you're coming from. Here's how the math works for common scenarios.

Rideshare from Common Locations (Estimated Round-Trip)

• Herndon / Reston: ~$30 to $50 round-trip by rideshare vs. $40 for 2 days in the Economy Lot
• Tysons Corner / Vienna: ~$60 to $90 round-trip vs. $40 (Economy) or $50 (Garage)
• Fairfax / Centreville: ~$50 to $80 round-trip vs. $40 to $50 for 2 days parking
• Downtown D.C.: ~$80 to $120 round-trip, while the Silver Line Metro (~53 minutes) costs a fraction of that

When Parking Wins

• Trips of 2+ days from Herndon, Reston, Sterling, or Ashburn
• Traveling with family (rideshare cost multiplies; parking cost doesn't)
• Early morning flights where rideshare surge pricing hits
• Trips of 4 days or more, where the Hyatt Regency at about $10/day undercuts the airport lots

When Rideshare Wins

• Same-day trips or stays under 24 hours
• Coming from downtown D.C. or Alexandria — Silver Line is often fastest and cheapest
• You don't want to deal with shuttle logistics or construction congestion

For travelers arriving via the Silver Line, Garage 1's underground tunnel connects directly to the Washington Dulles International Airport Metro station. Our Dulles Airport Metro parking strategy guide covers the best lots to use if you're combining driving, parking, and rail on the same trip.

How Can You Save Money on Parking at IAD Airport?

Saving money on IAD parking cost is mostly about picking the right lot for your trip length. Here are the strategies that actually work.

1. Reserve with the airport if you park on-airport. Booking at reserve.flydulles.com guarantees your space and gets the airport's lowest rates.
2. Use the Hyatt Regency off-site lot for trips of 4 days or more. At about $10/day it is about half the $20/day Economy Lot rate. Over 7 days that's about $67 vs. $140, a saving of about $73.
3. Don't pick the DoubleTree Washington Dulles for price. At about $26/day it costs more than the Economy Lot ($20) and the garages ($25). It makes sense for its vehicle allowance (full-size vans, pickups and large SUVs at no extra charge) or if you want a parking-only lot with a complimentary shuttle.
4. Choose Garage 1 or 2 over the Terminal Lot. You save $15/day vs. the Terminal Lot with only a slightly longer walk through a tunnel or covered walkway.
5. Plan around holiday peak periods. Thanksgiving, spring break and Fourth of July weekend are busy travel times, so book ahead.
6. Check TSA PreCheck status. TSA PreCheck speeds up security, which means you can arrive later and spend less time in short-term parking if you're picking someone up or dropping off.
7. Use the cell phone lot. If you're picking someone up, the free cell phone lot at 44910 Autopilot Dr costs nothing, so there's no need to pay for Terminal Lot parking while you wait.

IAD is also in the middle of a $7 billion capital improvement program. Concourse E opens fall 2026, and the D2 project (replacing Concourses C and D) begins October 2026. Construction may cause minor congestion near the terminal — budget extra time and consider checking the Waze live traffic map before you leave for the airport.

What Is the Cheapest Parking Option at Washington Dulles Airport?

The cheapest on-airport option is the Economy Lot at $20/day. The cheapest option on Triply is the Hyatt Regency Dulles Airport at about $10/day, with a complimentary shuttle to the terminal and a 4-day minimum booking.

For budget travelers on multi-day trips, the Hyatt Regency is the one off-site lot Triply sells that beats the airport on price. A 5-day trip at about $10/day costs about $48 total, vs. $100 in the Economy Lot or $125 in Garage 1. The DoubleTree Washington Dulles, at about $26/day, does not save money against either.

Is There a Way to Park for Free at IAD?

Free parking at IAD is limited but available in one specific case. The Cell Phone Lot at 44910 Autopilot Drive is completely free, for up to 1 hour, for anyone waiting to pick up arriving passengers. You park, wait for a text that your passenger has landed, then drive to the terminal for pickup. It's intended for short waits only, not extended stays.

No other on-airport lot offers free parking. For more on what's actually free at Dulles, see our full guide on IAD airport free parking options.

Ready to Book IAD Parking at the Best Available Rate?

Parking at IAD airport cost ranges from about $10/day off-site to $45/day for curbside on-airport valet, and the right option depends on your trip length, flight time and how much walking you want to do. For trips of 4+ days, the Hyatt Regency Dulles Airport lot saves about 52% to 76% vs. the airport's own lots. For short trips or heavy bags, the Terminal Lot or Valet is worth the premium.
