FlightAware data shows live spikes in flight cancellation and delay activity, with 24,430 total delays and 936 cancellations reported worldwide on its live tracking page.
FlightAware’s live cancellations page lists “Total cancellations today: 936” and “Total cancellations within, into, or out of the United States today: 259,” reflecting elevated disruption across U.S. routes, according to the site’s published counters.
Travel reporting compiled by Yahoo (via a silive.com report) says Miami International Airport recorded 70 delays and 42 cancellations on Tuesday, and noted that American Airlines had 75 delays and 31 cancellations that same day.
The Yahoo piece also cites the Federal Aviation Administration’s traffic updates, warning that thunderstorms could produce additional delays or cancellations in Florida, Minneapolis-St. Paul, Houston and Denver — a reminder of how weather, rather than a single carrier issue, often drives wide-scale flight disruption.
Airline and airport disruption trackers such as FlightAware and FlightRadar24 publish disruption indexes and per-airport delay pages that show which hubs are most affected; FlightAware’s table lists busy U.S. airports such as Boston Logan and Seattle-Tacoma among those with elevated delays today.
Passengers planning travel should check airline apps and official airport pages for rebooking options and gate updates. For context on recent U.S. operational problems, airports have faced similar interrupting events this month — for example, the FAA imposed a ground stop at LaGuardia during thunderstorms on September 3, 2026, and San Diego recorded large delays after an unusual airspace object sighting earlier in the month.
Those earlier disruptions are documented in domestic coverage: the FAA ground stop at LaGuardia was reported on September 3, and San Diego delays tied to a drone or weather-balloon sighting were reported September 5, illustrating how both weather and airspace incidents can cascade into cancellations and long delays.
Flight trackers and the FAA publish near-real-time feeds that show cancellations and delays by carrier and airport; travelers can use those official feeds and individual airline travel-alert pages to check eligibility for rebooking or refunds.
