How to Get from DCA to Dulles: Reagan National to Dulles Transfer Guide

Getting from Reagan National (DCA) to Dulles International (IAD) takes 35 to 80 minutes, depending on your mode of transport and when you travel. The Metro Silver Line now connects both airports with one transfer downtown, and rideshare is the faster call if you have bags or are running on a tight schedule. The two airports are about 27 miles apart, but highway traffic can stretch a 40-minute drive into 90 minutes on a weekday afternoon.

Can You Make a Same-Day Connection Between DCA and IAD?

Yes, with the right buffer. Book at least 3 hours between your DCA arrival time and your IAD departure time. That covers the transfer itself plus time for IAD check-in and security. Three and a half hours is safer if your DCA arrival is anywhere near the weekday evening rush.

What you cannot do is assume the transfer is short because the two airports share a metro area. They are not close. Dulles sits 26 miles west of downtown DC in Loudoun County, and every route between the two airports passes through or around the I-66 corridor, one of the more congested stretches of road in the region during peak hours.

What You Need to Know Before You Go

Rush hour on I-66 runs roughly 6:30 to 9:30am westbound (toward Dulles) and 3:30 to 7pm eastbound (toward DCA and downtown). A drive that takes 35 to 40 minutes at 11am can easily stretch to 70 to 90 minutes during those windows. The GW Parkway offers an alternate route from DCA that bypasses some of the DC-side congestion, but it cannot absorb heavy traffic reliably.

The Metro Silver Line is the most predictable option when you are not rushed. It runs on a fixed schedule and is not affected by road conditions. The tradeoff is time: the full rail journey from DCA to IAD takes 65 to 80 minutes, including the transfer downtown.

If you are connecting same-day and have a checked bag, factor in the recheck at IAD. That adds at least 15 to 20 minutes at the counter on top of your transfer time. Carry-on only makes the whole operation significantly faster.

Getting from DCA to IAD: All Your Options

Metro Silver Line

The Silver Line extension reached Dulles International in November 2022, the first time DC’s rail network connected the airport. It is now the cheapest and most predictable way to make this transfer, provided you have enough time.

The route from DCA:

1. Take the Blue or Yellow Line from Reagan National Airport station toward downtown DC.
2. Transfer to the Silver Line at Metro Center (easiest on Blue Line) or at Rosslyn.
3. Ride the Silver Line outbound toward Loudoun County. The final stop is Washington Dulles International Airport.

Total journey time: 65 to 80 minutes including the transfer. The Silver Line leg from Metro Center to Dulles alone takes about 45 to 55 minutes across 16 stations. Trains run every 6 to 12 minutes during peak hours and every 15 to 20 minutes off-peak. Check the WMATA app for real-time departures before you board.

Cost: Under $7 one-way with a SmarTrip card (as of early 2026; verify current fares at wmata.com before travel). Load a SmarTrip card at any station kiosk using cash or card. Peak fares are marginally higher than off-peak, typically under $1 difference.

Luggage note: Both stations have escalators and elevators. Silver Line cars have open luggage areas at the ends. A rolling carry-on is no problem. Two large suitcases on a crowded rush-hour train is uncomfortable for everyone. If you are traveling with checked-bag-sized luggage, take a rideshare instead.

Metrobus 5A

The 5A bus connects Dulles Airport to L’Enfant Plaza in downtown DC via Rosslyn. It does not serve Reagan National directly. To use it for a DCA-to-IAD transfer, you would take the Metro from DCA to L’Enfant Plaza or Rosslyn first, then catch the 5A west to Dulles.

The Silver Line made this trip mostly obsolete for airport transfers. The 5A is worth knowing about only if the Metro is disrupted or you are already near L’Enfant Plaza or Rosslyn when you need to get to Dulles.

Key details (as of early 2026; verify at wmata.com before travel):

• Fare: approximately $7.50
• Frequency: every 40 to 80 minutes. Not reliable for tight connections.
• Journey time from L’Enfant Plaza: 40 to 60 minutes to Dulles
• Stops: L’Enfant Plaza, Rosslyn, Dulles terminal

The biggest problem with the 5A is the gap between buses. Miss one and you could wait over an hour for the next. Check the WMATA trip planner for the next departure before committing to this option.

Rideshare (Uber or Lyft)

Off-peak, a rideshare from DCA to IAD runs $50 to $75 and takes 35 to 45 minutes. During rush hour, expect $70 to $120 and anywhere from 60 to 90 minutes depending on I-66 conditions.

This is the right call if you have luggage larger than a carry-on, are traveling in a group, or need to make the connection in under 3 hours total. One person, one carry-on, off-peak travel: the Metro saves money. More than one person or more than one bag: rideshare is the practical choice.

At DCA, rideshare pickup is from the designated Rideshare/TNC area. Follow signs from Terminals A, B, or C. Wait times at DCA are typically 5 to 12 minutes, longer during peak departure windows. Drop-off at IAD is at the Departures level. Most app-dispatched drivers use the Dulles Access Road (a toll road), which is the fastest route to the terminal.

Taxi

Metered taxis from DCA to IAD run $75 to $120 before tip. The main advantage over rideshare is no surge pricing. During high-demand periods, a metered cab may end up cheaper than a surge-priced app. Taxi stands are at the Arrivals level at both airports.

At DCA there is typically a queue during busy periods. You can state your destination before getting in, and the driver should take the Dulles Access Road for the fastest route.

Rental Car

This makes sense only if your itinerary has a gap of a day or more between the two flights. The drive from DCA to IAD off-peak is about 35 to 45 minutes via I-395 and the Dulles Access Road. For same-day connections, skip this option: dropping off the rental at IAD’s car rental center and taking the automated people mover to the terminal adds 30 to 45 minutes to your total transfer time.

Same-Day Connection: How Much Time Do You Actually Need?

Work backwards from your IAD gate.

Allow:

• 20 to 30 minutes to exit your DCA gate and reach the curb or Metro platform
• 35 to 80 minutes for the transfer, depending on mode and time of day
• 60 minutes to reach your IAD gate (carry-on only); 90 minutes if you are rechecking a bag

That totals a minimum of 1 hour 55 minutes if everything runs on time. Build in a buffer. Three hours between DCA arrival and IAD departure is the safe minimum. If the DCA arrival is between 3pm and 7pm on a weekday, add another 30 minutes for traffic risk.

If your DCA flight is delayed: start the rebooking process while you are still in the air. If the two tickets are separate bookings across different airlines, you are not automatically rebooked. Get on the phone or the airline app before you land.

When I-66 Is a Parking Lot

The I-66 westbound corridor, especially between Rosslyn and the Dulles Toll Road entrance near Fairfax, backs up predictably on weekday afternoons from about 3:30 to 7pm. This is not random. It happens consistently during that window.

If you are in a rideshare sitting in that traffic, options are limited. The GW Parkway from DCA bypasses some DC-side congestion but eventually merges near the same bottleneck. A driver who knows the area may route via Route 7 through Falls Church to the Dulles Toll Road further west, which can help.

The Metro Silver Line bypasses all of this. On any weekday afternoon where you have 90 minutes or more to get from DCA to IAD, the Metro is the more reliable choice. For broader context on navigating both airports and the city in between, the Washington DC layover guide covers what is worth your time if you have hours to fill at either end.

Practical Info

IAD to DCA (reverse): The same options apply in reverse. Metro Silver Line takes 65 to 80 minutes. Rideshare from IAD to DCA runs $55 to $90 off-peak. IAD has a designated rideshare pickup area on the lower Arrivals level.

Luggage storage: Neither DCA nor IAD has publicly accessible luggage storage outside the security zones. If you need to store bags between flights, check for partner locations near downtown DC via services such as Radical Storage (verify availability before travel).

Allow enough time back to DCA: If you are returning to DCA from IAD, leave at least 90 minutes for the Metro transfer plus time to reach your gate. Add 30 minutes if departing during the weekday rush.

Lounge access at IAD: If you have a long wait between the DCA arrival and the IAD departure, Dulles has multiple lounges across its terminals. Lounge access via credit card or day pass can make a 3-hour gap substantially more comfortable. See the guide to lounge access without a premium card for practical options.

FAQ

How long does it take to get from DCA to Dulles by Metro?

The Metro Silver Line from Reagan National to Dulles International takes 65 to 80 minutes total, including the transfer at Metro Center. The Silver Line leg alone, from Metro Center to the Dulles Airport station, is about 45 to 55 minutes across 16 stops. Travel time is consistent because it does not depend on road conditions.

What is the cheapest way to get from DCA to IAD?

The Metro Silver Line is the cheapest option at under $7 one-way (as of early 2026). The Metrobus 5A costs roughly the same but requires an extra Metro leg from DCA first, making it slower without saving money. Rideshare starts at about $50 off-peak.

Can I make a same-day connection between DCA and IAD?

Yes, if you allow at least 3 hours between your scheduled DCA arrival and your IAD departure. Less than that is high-risk, particularly on weekday afternoons. The airports are 27 miles apart and every road route between them passes near the I-66 corridor, which routinely backs up during peak hours.

Is Uber from DCA to IAD reliable?

Reliable in terms of availability, not always in terms of time. Off-peak, expect 35 to 45 minutes and $50 to $75. During rush hour or bad weather, that can become 75 to 90 minutes and $90 or more with surge pricing. Pickup at DCA is organized and wait times are usually under 15 minutes. This is the best option for travelers with multiple bags or luggage larger than a carry-on.

What is the minimum connection time from DCA to IAD on the same day?

Budget 3 hours between DCA arrival and IAD departure as your minimum. That covers exiting your gate, making the transfer, and getting through IAD check-in and security with a carry-on. Add 30 minutes if you are rechecking a bag at IAD, and another 30 minutes if the DCA arrival is during the weekday afternoon rush.
