Duffy Says US Air Traffic Control and Airports Need Another $30 Billion

US Transportation Secretary Sean Duffy has put a new figure on what it will cost to modernise the country’s air traffic control system and airports: another $30 billion. He made the case on 23 September at the Aero Club of Washington, according to Aviation International News.

The new total is nearly $10 billion higher than the amount originally requested, AIN reported, a sign that the estimated scale of the programme has grown since the first ask.

Money already approved

Congress approved $12.5 billion in the previous year to modernise the air traffic system, after decades of congestion complaints and technical failures. Duffy’s latest request sits on top of that funding and covers both air traffic control equipment and airport projects. The AIN report did not detail how the $30 billion would be divided or what legislative vehicle Duffy expects to carry it.

The argument from the Northeast outage

The request came two days after an outage showed how fragile parts of the system remain. On 21 September the FAA halted flights at Newark, Philadelphia, JFK, LaGuardia and Teterboro after Philadelphia TRACON lost its primary communications circuit and its backup fibre line was found to have been cut at a construction site in New Jersey. Duffy said the incident underscored the need for infrastructure modernisation funding to prevent future disruptions.

Average delays at Newark reached 306 minutes by evening, and the stoppage came as around 130 world leaders arrived in New York for the United Nations General Assembly.

Technology on the same track

Modernisation is not only about cables and radars. On 21 September the FAA also began limited use of SMART, an AI-supported planning platform that combines about 200 data streams to anticipate congestion. Duffy said SMART “will slash those frustrating delays, reduce stress on air traffic controllers, and lower travel prices.”

The department’s pitch is that hardware, communications links and software tools need to be funded together. A new traffic management tool can only help if the circuits that carry data to controllers are resilient, and the Philadelphia episode showed what happens when a single link fails.

What to watch

The request now has to go through Congress. Lawmakers will want to see a breakdown of how the money would be spent, which facilities would be upgraded first and how the FAA would measure progress, none of which was in the material reviewed for this report. The agency also faces other pressures, including staffing, which remain outside this funding discussion.

Airlines, airports and controller unions have all argued for sustained investment in recent years. Duffy’s number gives them a new baseline for that debate, and the path through the appropriations process will show how much support it carries.
