Updated September 20, 2026: This story uses live or recently published sources where available. Flight totals can change throughout the day, so travelers should confirm the exact flight with the operating airline.
US air travel is moving through another high-disruption period, but the national picture is not the same as the status of any one flight. FlightAware's live snapshot currently shows 17,929 total delays worldwide, including 5,386 involving flights within, into or out of the United States. It also shows 1,042 cancellations worldwide, including 625 involving the United States. Those figures are live operational counts and can change before you reach the airport.
What is causing the disruption?
There is no single nationwide cause. Weather, air-traffic restrictions, airport congestion, aircraft positioning and crew availability can interact. The FAA's daily reporting system specifically warns that thunderstorms, low clouds and winds can slow operations at major airports, while recent Chicago storms produced large numbers of cancellations and FAA traffic-management measures.
Why today's cancellations are not all the same
A weather cancellation, an aircraft-maintenance cancellation and a planned schedule cut are different events. The distinction matters because the passenger's rebooking options and the likelihood of recovery can differ. Reuters reported this week that American Airlines, United Airlines and Southwest are also reducing or reassessing planned capacity because of higher fuel costs, including some later-2026 flying.
What travelers should do now
- Check the operating airline first, not just a third-party tracker.
- Check the departure and arrival airports.
- Look at the inbound aircraft when the airline provides that information.
- If you have a tight connection, ask about alternatives early.
- Keep receipts and booking records if your itinerary changes.
