The federal government is moving forward with a massive $22 billion overhaul of Washington Dulles International Airports. U.S. Transportation Secretary Sean Duffy confirmed the ambitious plan on Tuesday, May 12, 2026, aiming to transform the aging facility into a modern transit hub by 2034.

According to reporting by Reuters, Duffy announced the initiative at a Washington conference, signaling a major investments push. The comprehensive revitalization will replace decades-old temporary concourses and phase out the airport’s polarizing mobile lounges, all while preserving its iconic mid-century architecture.

The detailed blueprint, initially revealed by the industry publication Airport Architecture, accelerates a previously approved $7 billion master plan into an eight-year mega-project. This development follows a record-breaking year for Dulles, which handled 29 million passengers in 2025, representing a 6.4% increase from the previous year, according to MWAA data.

Infrastructure Upgrades and Architectural Preservation

The cornerstone of the $22 billion project is a delicate balance between modernization and historical preservation. The main terminal, designed by renowned Finnish architect Eero Saarinen and opened in 1962, will be protected and integrated into the new layout.

Expanding the Main Terminal and AeroTrain

According to industry research detailing the MWAA proposal, the plan allocates $6.2 billion to expand the main terminal 300 feet to the east and west. This expansion includes renovated ticket counters and a new above-ground connector to Concourse A.

Furthermore, a $3.75 billion expansion of the underground AeroTrain system will connect all concourses. This critical upgrade will effectively eliminate the need for the 1960s-era mobile lounges for regular passenger operations, addressing a long-standing grievance among travelers.

New Linear Concourses

The airport will transition to a highly efficient linear concourse layout, similar to Atlanta’s Hartsfield-Jackson. The 1980s-era Concourses C and D, originally built as temporary structures and often criticized for their cramped spaces, will be demolished. In their place, the MWAA plan outlines three major builds:

• Concourse B ($2.26 Billion): A new facility featuring 33 regional Commercial-Aircraft gates.
• Concourse C ($4 Billion): A massive buildout that will integrate the currently under-construction 14-gate Concourse E, which is slated to open in Fall 2026.
• Concourse D ($3.7 Billion): A new concourse dedicated to accommodating domestic flights.

Political Momentum and Industry Support

The accelerated timeline is heavily driven by the Trump administration. In December 2025, President Donald Trump publicly criticized the facility’s operational layout, prompting the Department of Transportation to issue a Request for Information for new terminal concepts.

Transportation Secretary Sean Duffy solidified this commitment during his recent remarks in Washington.

“We’re going to rebuild Dulles,” Duffy said.

United Airlines Backs the Vision

United Airlines, which accounts for nearly 70% of passenger traffic at Dulles, is a major proponent of the overhaul. United CEO Scott Kirby reportedly met with President Trump in February 2026 to discuss the hub’s future. According to industry reports, Kirby has praised the design, noting it will create beautiful, open spaces and potentially the best airport in the country.

Financial Implications and Funding Challenges

While the vision is grand, the financial mechanics of the $22 billion price tag, which covers construction, inflation, and financing over eight years, remain a complex puzzle.

Bonds, Fees, and Federal Subsidies

MWAA presentations indicate the project is proposed to be funded through $21.8 billion in new bonds and $1.1 billion in airport fees. However, Reuters reports that Secretary Duffy declined to specify the exact federal contribution during his Tuesday announcement.

Industry analysts warn that without substantial federal subsidies, the financial burden could shift to the airlines. Estimates suggest the cost per enplanement could soar to $90.64 by 2035, significantly impacting operating costs at the critical international gateway.

AirPro News analysis

The proposed Dulles revitalization represents a monumental shift in U.S. strategy infrastructure, contrasting sheer ambition against potential financial strain. Completing a $22 billion mega-project in just eight years is an aggressive timeline that will require unprecedented coordination between the MWAA, the Department of Transportation, and airline partners. While the elimination of the mobile lounges and temporary concourses will drastically improve the passenger experience, the looming threat of a $90+ cost per enplanement could force airlines to pass costs onto consumers if federal funding falls short. The careful preservation of Saarinen’s masterpiece, however, ensures that the airport’s cultural heritage will survive its operational transformation.

This article is based on an official press release from Ontario International Airport.

Airports (ONT) has officially initiated the environmental review process for a comprehensive expansion program named ONT BOLD (“Building Our Legacy & Destiny”). Announced on May 7, 2026, the project is designed to address rapid passenger growth and modernize the airport’s infrastructure to serve the expanding Inland Empire region.

According to the official press release from the Ontario International Airport Authority (OIAA), the airport has issued a Notice of Preparation (NOP) for an Environmental Impact Report (EIR). This regulatory milestone marks the first formal step in a phased development timeline that officials project could span up to 10 years following the receipt of environmental approvals.

The proposed expansion will feature a new 650,000-square-foot Terminal 3, the modernization of existing facilities, and the integration of advanced aviation technologies. By launching the California Environmental Quality Act (CEQA) review process, the OIAA aims to solidify ONT’s position as a premier Southern California passenger gateway and global supply chain hub.

Addressing Unprecedented Regional Growth

Surging Passenger Demand

The necessity for the ONT BOLD project is driven by significant growth since the airport returned to local control in 2016. According to project data, passenger volume has increased by nearly 70% over the past decade, with the airport now handling over 7 million passengers annually. During peak travel periods, current demand already exceeds the design capacity of the existing terminal facilities.

This surge mirrors the broader demographic trends of the Inland Empire, which is currently home to over 4.5 million residents and is projected to grow by another million by 2050. Airport officials note that when factoring in regional drive times, more than 10 million Southern Californians live or work closer to ONT than any other commercial airport.

Interim Upgrades Underway

While the ONT BOLD project represents a long-term solution, the OIAA is already executing interim improvements. An $11 million Transportation Security Administration (TSA) security expansion project is currently underway in Terminals 2 and 4. This interim project, which began in Spring 2025, is slated for completion in Fall 2026 to help manage immediate capacity constraints.

The ONT BOLD Master Plan

Terminal 3 and International Capacity

The centerpiece of the ONT BOLD program is the proposed Terminal 3. As detailed in the project announcement, this new three-level, 650,000-square-foot facility is designed to serve both domestic and international passengers. Crucially, Terminal 3 will feature a new Federal Inspection Services (FIS) facility. This addition is essential for processing international arrivals and securing certification from U.S. Customs and Border Protection (CBP), which will significantly boost ONT’s capacity as an international gateway.

In tandem with the new construction, the project outlines the modernization and expansion of Terminals 2 and 4, which were not originally designed to meet modern security and accessibility standards. The broader infrastructure overhaul also includes a new multi-story parking garage, optimized terminal roadways, upgraded taxiways, and a new Central Utility Plant and Fuel Farm.

Technological Innovation: MARS Gates

A standout feature planned for the new Terminal 3 is the implementation of Multiple Aircraft Ramp System (MARS) stands. Breaking from the conventional model of fixed aircraft-gate assignments, MARS gates utilize a network of adjustable walkways and overlapping stands. This flexible configuration can accommodate either two narrowbody aircraft or a single widebody jet simultaneously.

According to industry data provided in the project overview, this technology maximizes the utilization of existing tarmac space, effectively increasing airport capacity without requiring sprawling additional infrastructure. Furthermore, the system utilizes two passenger boarding bridges per gate, which is expected to drastically reduce boarding and deplaning times and improve the overall passenger experience.

Environmental Review and Community Engagement

The issuance of the NOP officially opens the public scoping phase of the CEQA review process. The OIAA has scheduled a Public Scoping Meeting for Thursday, May 21, 2026, from 5:30 to 7:30 p.m. at the OIAA Boardroom to gather community and stakeholder feedback. Written responses to the NOP must be submitted by June 8, 2026.

Local leaders emphasized the importance of community collaboration during this phase. Alan D. Wapner, President of the OIAA Board of Commissioners and Ontario Mayor pro Tem, highlighted the project’s regional significance in the official release:

“Project BOLD is about more than building facilities, it’s about building the future of this airport and the region we serve. As demand continues to grow, we have a responsibility to ensure ONT remains convenient, accessible and ready to connect the Inland Empire with the world. This is the first step in a transparent and collaborative effort to shape ONT’s next chapter.”

Curt Hagman, San Bernardino County Supervisor and OIAA Board Vice President, echoed this sentiment, noting the strategic nature of the expansion:

“ONT BOLD represents a thoughtful, phased approach to meeting the demands of a fast-growing region. We’re investing in infrastructure that strengthens our role as a major passenger gateway and global supply chain hub, while maintaining the ease and efficiency travelers value.”

Atif Elkadi, CEO of the Ontario International Airport Authority, also commented on the airport’s trajectory:

“We are proud of the trajectory we’re on, and even more excited about where we’re headed. We serve one of the most dynamic economic and population centers in the United States, and that gives us a unique opportunity, and responsibility, to lead.”

AirPro News analysis

The launch of the ONT BOLD environmental review signals a critical maturation point for Ontario International Airport. By investing heavily in international processing capabilities (the new FIS facility) and high-efficiency infrastructure like MARS gates, ONT is positioning itself to compete more directly with larger hubs such as Los Angeles International Airport (LAX). The emphasis on maintaining its reputation for convenience while scaling up operations will be a delicate balancing act over the projected 10-year construction period.

Financially, the OIAA has made it clear that projects of this scale are typically funded through a combination of airport revenues, debt, passenger facility charges (PFCs), and federal or state grants. By explicitly stating that no local tax dollars will be used, airport leadership is likely aiming to preempt local financial concerns ahead of the May 21 public scoping meeting. We will continue to monitor the CEQA process as specific designs and cost estimates are refined.
