IAD Global Gateway

Big changes are coming to Dulles! The recently announced transformation called Dulles Global Gateway will modernize and expand the airport with new and renovated facilities, enhanced passenger amenities, and improved ways to navigate the airport.

A project of this scale is bound to raise questions. Here are answers to some of the most common ones:

Are you keeping the Main Terminal architecture designed by Eero Saarinen?
Yes, the project will preserve Saarinen’s architecture and iconic main terminal.

Will this project mean higher airline ticket prices?
Airlines set ticket prices based on market conditions which are historically not correlated with airport costs.

Will everything happen at once?
The program will be built in phases. More information on the phasing is available here.

Will taxpayer money fund the transformation?
No, it will be funded by Airports Authority bonds which are paid back using revenue generated by the airport and fees charged to the airlines—not taxpayer money.

What does this mean for parking?
While the project will renovate and expand existing parking facilities and add another garage near the Main Terminal, expansion of parking space will keep pace with matching demand.

Why are you calling the project Dulles Global Gateway?
Because Dulles is the world’s gateway to the capital of the United States and for all of us in the capital region, it is our gateway to the world.

Why is the project called Dulles Global Gateway?

All projects under this program will enhance Dulles International Airport’s long-standing position as the National Capital Region’s “gateway to the world.” As the fastest-growing international gateway airport in the United States, and as the premier international airport for the Washington, D.C., region, the Dulles Global Gateway name reflects the airport’s position as the Washington, D.C., region’s premier international airport, with nearly 50 airlines serving more than 160 nonstop destinations around the world.

What will the Dulles renovation projects (IAD Global Gateway)  include?

• An expanded and upgraded the Main Terminal, with new and more-efficient ticketing areas and security facilities all on the same level to ease passenger flow and make the airport more “walkable” for travelers;
• International gates located in the expanded Main Terminal for greater efficiency and easier passenger access to U.S. Customs processing;  
• More close-in parking, more-convenient passenger drop-off areas near the main entrance for easy access to and from buses, taxis, limos and ride-share cars;
• New or upgraded concourses with wayfinding features and other services to give travelers a more efficient, relaxed and enjoyable time in the airport;  
• More-spacious gate areas with more comfortable seating options and features such as work stations and phone chargers;
• Extension of the underground AeroTrain system that connects the terminal and concourses, allowing retirement of the aging “mobile lounge” vehicles;  
• New and updated concessions to give travelers more shopping and dining options and a more vivid “sense of place” in the U.S. capital region;
• More and larger passenger lounges and other amenities to give travelers a more pleasant journey;
• Reimagined roadways throughout the airport campus to move traffic more efficiently.

What are the major phases of the project and their estimated timetables and costs?

The main phases of the project are as follows:

• Expansion of the Main Terminal (retaining Saarinen architecture) with new ticketing areas, an expanded U.S. Customs facility with new international gates nearby, baggage basement connections, a walkable connector to the current A/B Concourse, and replacing Concourse A’s regional gates with contact gates. Construction could begin in the spring of 2027. Estimated cost: $6.2 billion.
• Extension of the underground AeroTrain from the current Concourse A to the western side of the yet-to-be-built Concourse D and construction of a “center spine” tunnel for passengers and baggage transit from the current Concourse B (which will become Concourse A) to the new Concourse D. Construction is expected to begin in early 2028. Estimated cost: $3.75 billion.
• Extension of the currently under-construction Concourse E (to be renamed Concourse C) in three phases to add gates, connecting to an AeroTrain station for the western-most segment of the concourse, and construction a south-central utility plant. Design-Construction on the second and third segments began in 2026; final section is expected to begin in the summer of 2027. Estimated cost: $4 billion.
• Construction of a new concourse G at the southern end of the airfield in line with the Air Traffic Control tower. Gates will serve domestic flights, to be built in four phases to match demand. Design-construction of the first two phases on the eastern side of the airfield is expected to begin in the summer of 2027; construction of the final two phases is forecast to begin in the fall of 2039. Estimated cost: $3.7 billion.
• Demolition of the current C/D concourse will occur after replacement gates become available.  
• Construction of a 33-gate regional concourse in its place will be timed based on demand.  

What other projects are expected to happen on the landside?  

Projects beyond the terminals and airfield may include new parking structures, a new closer-in rental car center, new cargo facilities, potential development of a hotel, convention center and other businesses and entertainment venues. These projects, which add private investments to the mix through public-private partnerships, could push total investment across the Dulles campus to $30 billion, provide more jobs and new business opportunities to support local economic growth and make Dulles a popular destination for local residents as well as travelers.  

What new parking facilities will be built?

When demand requires additional spaces, parking facilities will be constructed. Initially, new levels will be added to the Saarinen Circle parking area just in front of the Main Terminal, to create more close-in parking within steps of the airport’s front door.  A new parking deck also is planned on the east side of the Saarinen Circle.  

How much taxpayer money will fund this $22 billion project?

No taxpayer funds are designated for this project, other than an anticipated federal grant for about $150 million to cover a small fraction of the demolition of the aging C/D Concourse. The Dulles Global Gateway initiative is being financed by the Airports Authority and ultimately will be paid for by the revenue generated by the airport such as concessions, parking and for normal fees charged to the airlines for operating at Dulles.  However, if government grants are made available, the Airports Authority will apply for them.  

How are you preserving the Saarinen architecture?  

The Administration’s initiative for modernizing Dulles clearly calls for preserving the Saarinen architecture and tower in the airport’s Main Terminal. The Airports Authority is consulting with the Saarinen family on plans for the project to ensure that Saarinen’s architectural vision is maintained.

How much will the project increase costs to airlines (cost per passenger) and when?

The cost per enplaned (departing) passenger (also known as CPE, which is the standard metric used in the aviation industry) is influenced by increases in costs and mitigated through the growth of passengers and non-airline revenue sources such as terminal concessions, parking and real estate rents.  Through the Airports Authority leadership’s careful management of these factors, airlines today at Dulles have a lower cost per passenger than they did 20 years ago.  That has put the airport in a very competitive position within the industry with room for investment.  Airports Authority leadership is committed to this continued fiscal discipline to ensure that Dulles remains comparable to other similar hubs now and in the future through phased construction to match the growth in consumer demand. Debt-service costs will be incorporated into Dulles Airport’s charges to airlines as those expenses are incurred over the years. Dulles’ per-passenger cost to airlines is expected to remain comparable with other airports, many of which are also engaged in major construction projects that will escalate their costs.

What impact will these projects have on airline ticket prices at Dulles?  

The cost per enplaned (departing) passenger (CPE ) is an industry metric used by airports and airlines to determine average costs for operations at a particular airport on a per-passenger basis. It is not a major component of air fares or ticket prices. Air fare is a market-driven determination made by airlines serving any airport or destination.  

Dulles International Airport’s record-setting passenger growth is outpacing its current terminal gate capacity. The airport’s existing gates are fully utilized several times per day, and passengers fill the waiting areas and concession locations. The new Concourse E will give passengers direct access from the airport's AeroTrain system while providing an enhanced customer experience and increasing the airport's capacity for domestic and international flights. The facility can be expanded through future projects with minimal impact on airport operations. 

Concourse E Will Feature: 

• Spacious and comfortable seating areas
• Jetbridges to aircraft at each gate
• 46,000 square feet of concessions space
• 40,000 square foot airline club
• Direct access to AeroTrain
