Washington Raises Air Traffic Control Modernization Request to $50 Billion After Flight Halt
Key Facts
The U.S. administration raised its funding request for air traffic control modernization to $50 billion late Friday, November 13, after seeking $30.1 billion earlier in the day to upgrade airports and the system, Reuters reported. The increase followed a Federal Aviation Administration nationwide ground stop for departures that lasted about five hours and affected thousands of flights. The administration said the funding targets an aging network, while American, Delta, United and Southwest announced their support for the initial request. Transportation Secretary Sean Duffy said modernizing the system was "an emergency," adding: "What could be more important than having an air traffic control system that actually works?" The move puts aviation infrastructure funding on the political agenda after an outage exposed its broad operational impact.
The initial request included $10.1 billion to modernize air traffic control, Reuters reported, including $7.2 billion for a common automation platform and controller workstations, and $2 billion for cloud computing. The plan also included $2 billion to replace and upgrade FAA air traffic control towers, and $18 billion for airport projects. Of that amount, $10 billion was earmarked to modernize or replace aging terminals. These items show that the initial request combined upgrades to air traffic control systems and airport facilities, before the administration raised the total to $50 billion later that same day. The information available did not break down the additional amount after the request was raised.
The FAA said the ground stop was issued after communication problems affected several air traffic control centers, and that its technicians were investigating the issue. Officials said new technology added to the system had burdened older components, causing intermittent gaps in communications and radar. Duffy said old switches and routers had been overloaded with data, while newer switches operating on Internet Protocol technology had not failed. He added that the system relied on outdated analog communications and that the department had replaced 68% of its old copper communications network with high-speed fiber. Officials linked the technology upgrade to the need to address the existing equipment supporting it.
The ground stop disrupted air traffic and passengers during the crisis. The Associated Press estimated that about 11,000 flights carrying more than 1.5 million passengers were scheduled to depart U.S. airports after 4 p.m. Eastern time on November 13. By 7:05 p.m., 670 flights had returned to their airports of origin and 157 had been diverted to other airports, according to Cirium data cited by the agency. Duffy said the airspace reopened at 8:15 p.m. Eastern time, but noted that flights would not resume immediately. Officials said returning aircraft and crews to their locations would delay the return of the flight schedule to normal.
The new funding request comes after Congress approved $12.5 billion over five years in July 2025 to modernize air traffic control and increase controller hiring, Reuters reported. Congress also approved $1.9 billion to replace aging air traffic control centers, which manage traffic between airports, as Duffy noted. In the context of aviation safety risks, an airborne collision at Ronald Reagan Washington National Airport killed 67 people in January 2025. Duffy said fixing the system required full funding for a new build rather than scattered patches, describing the issue as one that affected the safety of American families. This background frames a long-term modernization program, while details of Congress's response to the expanded request remain before lawmakers.
In the near term, Duffy said he expected flights to be operating again before the Thanksgiving holiday travel peak during the following weekend, but also noted the possibility of further disruptions. The company closed at $86.25 on November 13, according to EL7 data. Officials said restoring the full flight schedule could take days because aircraft and crews were out of position, while Duffy explained that reopening the airspace did not mean every flight would take off immediately. A return to regular operations depends on aircraft and crews getting back into position and communications stabilizing at control centers. Officials gave no assurance that the outage would not recur.
