Nothing sells a funding request quite like switching off the whole sky. On Friday, Nov. 13, the Federal Aviation Administration halted every departing US flight for more than four hours after communication failures hit multiple air traffic control centers. Hours earlier, the White House had asked Congress for another $30.1B to modernize the system that broke.
The bill comes due: More than 10K flights were disrupted, and the stop was lifted Friday evening, with cancellations rolling into the weekend. Cirium counted ~11K flights scheduled to depart after 4 p.m. ET, carrying more than 1.5M passengers. JetBlue told staff it would scrap the rest of Friday's domestic flying plus Saturday departures to reset crews and aircraft.
- Airline shares slipped after hours, with United down 1.5%, Delta off 2%, and American 1.4% lower.
- Southwest fell 1.7%, and the US Global Jets ETF dropped 1.4%, against a 0.6% after-hours dip for.
What Multi-Day Cancellations Actually Cost
Delta's 2024 CrowdStrike meltdown offers the closest precedent, though it's history and not a forecast for this event. Roughly 7K cancellations over five days cost the carrier an estimated $380M in direct revenue plus $170M in extra non-fuel costs. Passengers have a backstop here. Under a Transportation Department rule, a cancelled flight entitles you to a refund if you decline rebooking.
- Congress approved $12.5B for air traffic control modernization in July 2025, now called a down payment by officials.
- The new ask includes $10.1B for control upgrades, with $2B for cloud computing and airspace telecommunications.
Watch the calendar: The administration wants the Republican-led Congress to move in the final weeks of the year, since Democrats take control in January. Major carriers including American, Delta, United, and Southwest back the request. Officials describe the cause as a telecommunications outage still under review, and say it's unrelated to Thursday's Microsoft outage. The FAA hasn't published a final root cause, and Thanksgiving is two weeks out.
