The Federal Aviation Administration (FAA) has awarded $870 million in FAA airport infrastructure grants covering 339 projects at airports across 44 states and two US territories, the agency announced on 4 August 2026. The package is the fifth and final instalment under the Airport Infrastructure Grant (AIG) programme, bringing the total disbursed since fiscal year 2022 to $14.5 billion, according to the FAA’s AIG programme page.
Largest grants: LAX leads, Miami and smaller airports follow
Los Angeles International Airport (LAX) is the biggest single beneficiary, receiving $289 million for a new terminal access road. Miami International Airport (MIA) will receive $50 million to reconstruct part of its terminal roof. Several regional and smaller airports are also in the funding round: Akron-Canton Airport in Ohio receives $9.1 million to rehabilitate passenger boarding bridges and rebuild airport facilities; Juneau International Airport in Alaska gets $4.2 million for snow removal equipment; Charleston International Airport in South Carolina receives $3.7 million for a terminal expansion; and Sugar Land Regional Airport in Texas is awarded $3.5 million for runway reconstruction.
Washington Dulles International Airport, which is separately the subject of a much larger capital programme valued at more than $20 billion over the next decade, also received a share of this AIG round. According to Construction Dive, Dulles received approximately $23.11 million through the programme, a figure that sits well below the scale of the broader overhaul being developed by United Airlines, the Metropolitan Washington Airports Authority and the US Department of Transportation.
The AIG programme funds runway and taxiway work, terminal improvements, baggage systems, airport roads, planning and other safety-related projects. Airports receive a portion of available funding based on passenger traffic, and the FAA can award additional money when the cost of an airport’s planned projects exceeds its annual allocation.
FAA airport infrastructure grants close out a five-year programme
The AIG programme was established under the 2021 Infrastructure Investment and Jobs Act, which set aside $15 billion for airport infrastructure over five years beginning in FY 2022. The FAA’s own figures confirm this latest $870 million disbursement is the fifth and final instalment, with the cumulative total across the programme reaching $14.5 billion. The pace of disbursement has been a stated priority for the agency’s leadership.
US Transportation Secretary Sean Duffy said the investment was aimed at delivering a more seamless experience at airports of all sizes. ‘From our regional hubs to some of America’s busiest airports, we are investing in critical infrastructure that will provide American families with a more seamless, efficient travel experience for years to come,’ Duffy said.
FAA Administrator Bryan Bedford framed the speed of grant release as a deliberate response to rising passenger volumes. ‘We’re making airports safer and more convenient for travelers across the U.S.,’ Bedford said. ‘We’re releasing grants at record speed to ensure we keep up with the growing demand for travel.’ The FAA did not provide construction schedules for the projects highlighted in its announcement.
Dulles overhaul remains a separate, far larger undertaking
The $870 million package should not be conflated with the proposed Dulles redevelopment, which was announced separately last week and is on an entirely different financial scale. That capital programme, valued at more than $20 billion over the next decade, calls for more than five million square feet of new or renovated space. It includes a replacement for Concourses C and D, upgrades to the main terminal and ticketing areas, additional gates, expanded security screening, new baggage systems, and further lounges and concessions.
The original Eero Saarinen-designed terminal at Dulles will be preserved under the plan. The AeroTrain system would also be expanded, and a central walking tunnel added, which would allow the airport to retire its ageing mobile lounges. A new Concourse E with 14 United gates is already under construction and is expected to open in late 2026.
With the AIG programme now fully disbursed, future federal airport capital support will depend on separate appropriations or programme reauthorisation. The FAA’s fifth and final AIG instalment closes a chapter in US airport infrastructure funding that began with the 2021 act.
