(UNITED STATES) — U.S. airlines recorded 1,286 cancellations and 9,783 delays on July 6, 2026, as weather-driven FAA ground stops disrupted operations at several major airports.

FlightAware tracked the cancellations and delays on flights within, into, or out of the United States. More than 1,000 flights were canceled in a single day, creating widespread disruption across the national air network.

The FAA imposed ground stops at major hubs as weather affected airport operations. LaGuardia, Boston Logan, John F. Kennedy International Airport, Newark, and San Francisco ranked among the airports tied to the disruption.

Republic, JetBlue, Endeavor Air, Delta, and PSA Airlines recorded the hardest-hit operations that day. The cancellations and delays affected both flights traveling through the airports and services scheduled to depart from or arrive at them.

Ronald Reagan Washington National Airport also faced a separate interruption tied to America 250 events. The airport was scheduled to suspend operations on July 4 starting at noon, with the closure expected to trigger additional cancellations.

The July 6 disruption came during a holiday period that placed added pressure on the U.S. air system. Weather at major hubs combined with the airport suspension in Washington to create separate sources of interruption across the network.

By July 8, conditions had eased but remained unstable. FlightAware recorded 424 cancellations and 2,785 delays across a dozen states that day.

The figures represented a lower level of disruption than the July 6 total, but cancellations and delays continued at multiple locations. Carrier-specific cancellations remained part of the problem even as the nationwide spike receded.

The FAA said more than 300,000 flights took off uninterrupted over the July Fourth weekend. That figure covered the broader holiday period, while the FlightAware counts captured cancellations and delays on specific days.

The contrasting figures showed how uneven the travel period became. More than 300,000 flights departed without interruption over the weekend, yet weather-related ground stops and airport closures still produced thousands of delays and cancellations at affected hubs.

LaGuardia and the other airports tied to the July 6 disruption serve as connecting points for flights moving through different parts of the country. When weather stops operations at those hubs, delays can spread to flights scheduled elsewhere, as aircraft and crews remain out of position.

The July 6 totals included flights within the United States as well as flights traveling into or out of the country. FlightAware’s count therefore covered a broad range of domestic and international services linked to the U.S. system.

Airlines with heavy disruption included both large carriers and regional operators. Republic, Endeavor Air, and PSA Airlines operate alongside larger brands in the U.S. network, while JetBlue and Delta also ranked among the carriers facing the greatest effect that day.

Ground stops differ from ordinary delays because they halt or restrict departures headed toward an affected airport. Weather conditions at the hub can force the FAA to manage traffic before aircraft leave their origin airports, limiting the number of flights entering the disrupted area.

The July 6 numbers reflected the result of those restrictions across the network. FlightAware counted 1,286 cancellations and 9,783 delays, while the FAA ground stops affected operations at several major hubs.

Washington’s July 4 airport suspension added another disruption during the same holiday period. Ronald Reagan Washington National Airport was scheduled to stop operations at noon for America 250 events, with airlines expected to cancel flights affected by the closure.

By July 8, FlightAware’s totals had fallen to 424 cancellations and 2,785 delays across a dozen states. The system had begun to recover, but the remaining figures showed that operations had not returned to a fully stable pattern.

The changes from July 6 to July 8 followed two different phases of the disruption. The first brought more than 1,000 cancellations and nearly 10,000 delays in one day; the second brought lower totals spread across a dozen states.

FlightAware’s figures provided the daily count of cancellations and delays, while the FAA supplied the broader holiday measure of uninterrupted departures. Together, the figures captured the difference between overall holiday operations and the concentrated disruption at weather-affected airports.

Airlines continued dealing with the effects of the earlier interruptions as the system eased. Flights canceled at one hub can leave later services without an aircraft or crew, creating carrier-specific cancellations after the original weather event has passed.

The July 8 figures included 424 cancellations and 2,785 delays, indicating that the disruption remained active even after the sharpest increase had passed. Major hubs continued to experience lingering delays, and individual airlines faced cancellations tied to their own schedules.

The airport suspension in Washington followed a separate timetable from the July 6 weather disruptions. Ronald Reagan Washington National Airport was scheduled to suspend operations on July 4 beginning at noon, while weather-related FAA ground stops affected LaGuardia, Boston Logan, JFK, Newark, and San Francisco on July 6.

Holiday travel therefore faced more than one operational constraint. Weather disrupted flights at major hubs, while the America 250 events led to a planned suspension at Ronald Reagan Washington National Airport.

The FAA’s figure of more than 300,000 uninterrupted departures over the July Fourth weekend showed that most flights continued to operate. The daily cancellation and delay counts, however, reflected the pressure concentrated at particular airports and among particular carriers.

By July 8, the system was easing rather than fully settled. FlightAware still showed hundreds of cancellations and thousands of delays across a dozen states, leaving passengers and airlines to manage the remaining effects of the holiday disruptions.
