I don’t have access to live flight data right now, but here’s the latest situation based on recent reports:

• What’s happening: The FAA has ordered temporary reductions in flight capacity at a group of major U.S. airports due to the ongoing government shutdown, leading airlines to cancel or reduce numerous flights for Friday. Estimates indicate hundreds to over 800 cancellations nationwide on Friday, with many flights affected concentrated at large hubs. The reductions are being implemented to ease pressure on air traffic control operations during the shutdown.

• Which airlines are most affected: The largest U.S. carriers—American, United, and Delta—have each announced sizable daily cancellations (on the order of a couple hundred flights combined per day initially), with smaller but still significant cuts affecting other carriers as well. Delta and United have reported cancellations in the low hundreds per day when combined with weekend adjustments; American has indicated roughly a 4% to 4–5% reduction in schedules for the period.

• Airports impacted: The reductions cover 40 major airports across the U.S. The FAA’s order targets these hubs to manage traffic volumes amid staffing constraints tied to the shutdown. The list includes many of the nation’s largest airports, such as those in Atlanta, Dallas, Los Angeles, New York/Newark, Miami, Denver, and others.

• What travelers should do: If traveling Friday or in the near term, check your flight status with your airline, verify alternate routes or return dates, and stay updated on official FAA and airline communications. Expect potential rebooking options, delays, and longer reassessment windows for itineraries affected by the reductions.

Direct answer:

• On Friday, hundreds of flights were canceled or reduced as the FAA imposed a 10% capacity reduction at 40 airports due to the government shutdown. Major airlines (American, United, Delta) reported substantial cancellations (roughly 170–220 flights per day for each on Friday, with additional impacts over the weekend), and total Friday cancellations were reported in the hundreds to over 800 nationwide, depending on the source. Airports across the 40 affected hubs were impacted, with delays and rebooking options commonly available for affected travelers. Travelers should monitor their specific flight status and airline communications for the most accurate, up-to-the-minute information.
