Flight cancellations continued across the US today, with 4,798 delays and 689 cancellations reported nationwide. Chicago O’Hare is the biggest disruption hotspot, with over 1,000 delays, while passengers at New York JFK are also facing heavy cancellations. LaGuardia, Reagan National, Newark Liberty, Hartsfield-Jackson Atlanta, Boston Logan and Philadelphia International are also facing significant disruption as thunderstorm activity prompts FAA traffic-management restrictions at several major hubs. Airlines including American Airlines, Republic Airways, SkyWest, Endeavor Air, JetBlue and PSA Airlines are experiencing substantial operational pressure.

• Chicago O’Hare faced the highest delays and cancellations in the US.
• Thunderstorms have triggered FAA ground stops and ground-delay programs at several major hubs.
• American Airlines has the highest delay total, with 423 delays.
• Republic Airways has the highest cancellation total, with 145 cancellations.

What Today’s Flight Disruptions Reveal

The disruption is not being spread evenly across the US network. It is particularly concentrated around major Midwest and Northeast hubs, where thunderstorms have forced air traffic managers to restrict the flow of aircraft.

Chicago O’Hare stands apart from the other airports, recording 1,055 delays and 266 cancellations. Its cancellation count alone represents about 38.6% of the 689 cancellations nationwide.

The pattern at JFK is notably different. Its 141 cancellations account for about 20.5% of all US cancellations today.

LaGuardia and Reagan National are also under significant cancellation pressure, with 89 and 72 cancellations respectively. By contrast, Hartsfield-Jackson Atlanta has 381 delays but only six cancellations, illustrating how severe operational disruption can take the form of prolonged delays rather than widespread flight cancellations.

Boston Logan has recorded 205 delays and 26 cancellations, while Philadelphia International has 151 delays and 30 cancellations. The result is a network where some airports are absorbing large numbers of delayed flights while others are seeing a greater proportion of scheduled services cancelled outright.

Worst-Hit US Airports

Chicago O’Hare

Chicago O’Hare is the clearest focal point of today’s disruption, with 1,055 delays and 266 cancellations. Thunderstorms have affected operations through both a ground stop and a ground-delay program, restricting the movement of flights through one of the country’s busiest aviation hubs.

The latest operational condition is more encouraging but remains disruptive: departure delays are averaging 75 minutes and are decreasing. That improvement does not erase the scale of disruption already affecting passengers and airline schedules.

John F. Kennedy

JFK has recorded 317 delays and 141 cancellations, giving it one of the highest cancellation totals.

Thunderstorms prompted an earlier ground-delay restriction, with the average delay reaching 177 minutes. The combination of substantial delays and an unusually high cancellation count makes JFK one of the most operationally pressured airports in the country today.

LaGuardia

LaGuardia is dealing with 354 delays and 89 cancellations. Thunderstorms prompted an earlier ground-delay restriction, while the latest departure-delay condition is averaging 30 minutes and decreasing.

For passengers, the improving departure-delay trend is positive, but the cancellation total means schedule disruption remains significant. Travelers can still encounter revised departure times or changes to their planned journeys.

Newark Liberty

Newark Liberty has recorded 269 delays and 60 cancellations as thunderstorms affect operations. An earlier ground-delay restriction was imposed, while the latest departure-delay condition is averaging 15 minutes and increasing.

That upward trend is important for travelers because the current delay environment is not moving in the same direction as LaGuardia’s. Passengers should continue checking their flight status rather than assuming an earlier delay estimate will remain unchanged.

Reagan National

Reagan National is seeing 296 delays and 72 cancellations. Thunderstorms triggered an earlier ground-delay restriction, with average delays reaching 59 minutes.

The disruption adds pressure to the wider Washington-area aviation network, where passengers are facing both delayed departures and a substantial number of cancellations.

Hartsfield-Jackson Atlanta

Atlanta has recorded 381 delays but only six cancellations, creating one of the clearest examples today of an airport experiencing heavy operational pressure without a comparable cancellation wave.

Thunderstorms prompted an earlier ground stop. The latest departure-delay condition is averaging 60 minutes and increasing, meaning the airport is still facing worsening delays even though cancellations remain relatively limited.

Airlines Facing The Greatest Operational Pressure

American Airlines

American Airlines has recorded 423 delays and 54 cancellations, giving it the highest delay total. The delay count underscores the scale of operational pressure affecting its schedule, while the cancellation total adds another layer of disruption for passengers.

Republic Airways

Republic Airways has recorded 304 delays and 145 cancellations. Its cancellation count is the highest.

SkyWest

SkyWest has recorded 357 delays and 76 cancellations. Its delay total is second only to American Airlines, showing that its operational pressure is weighted more heavily toward delays than cancellations.

Endeavor Air

Endeavor Air has recorded 261 delays and 100 cancellations. Reaching triple-digit cancellations places the carrier among the airlines facing the strongest cancellation pressure today, alongside a substantial volume of delayed flights.

JetBlue

JetBlue has recorded 261 delays and 68 cancellations. Its disruption includes a sizeable delay burden as well as dozens of cancelled flights, adding to the operational pressure visible across the US network.

FAA Airport Disruptions Today

The operational picture varies significantly from airport to airport.

At Chicago O’Hare, an earlier ground stop and ground-delay program addressed thunderstorm-related constraints. The latest condition is a departure delay averaging 75 minutes, with the trend decreasing.

At LaGuardia, an earlier ground delay was followed by the latest departure-delay condition averaging 30 minutes and decreasing.

At JFK, the earlier thunderstorm-related ground delay was accompanied by a 177-minute average delay.

At Newark Liberty, an earlier ground delay was followed by the present departure-delay condition averaging 15 minutes and increasing.

At Reagan National, an earlier ground delay linked to thunderstorms produced an average delay of 59 minutes.

At Atlanta, an earlier ground stop was followed by a departure-delay condition averaging 60 minutes and increasing.

The contrast matters: some airports are showing signs of improving departure performance, while others are still seeing delays increase.

What Travelers Should Expect

Passengers traveling through Chicago O’Hare, JFK, LaGuardia, Newark Liberty, Reagan National, Atlanta and Boston Logan should be prepared for schedule changes today.

Conditions are changing at different speeds across the network. O’Hare’s latest average departure delay is decreasing, as is LaGuardia’s, while Newark and Atlanta are seeing their latest average departure delays increase. JFK stands out for its high cancellation count alongside substantial delays.

Travelers should check their flight status before leaving for the airport, allow additional time for disrupted operations and keep airline notifications active. Gate assignments and departure times can change as traffic-management conditions evolve.

Overview of Flight Disruptions

The US aviation network is dealing with 4,798 delays and 689 cancellations across flights within, into, or out of the country today. Chicago O’Hare remains the biggest hotspot among US airports, while JFK has the highest cancellation count.

Significant disruption is also affecting New York, with LaGuardia and Newark Liberty facing substantial delays and cancellations, while Reagan National, Atlanta, Boston Logan and Philadelphia International are also under pressure.

Among the major airlines, American Airlines, Republic Airways, SkyWest, Endeavor Air, JetBlue and PSA Airlines are recording substantial disruption. Thunderstorms and the resulting FAA traffic-management measures are driving restrictions at several major hubs, producing a mix of ground stops, ground delays, departure delays and cancellations.

With conditions varying sharply from one airport to another, passengers should continue monitoring flight schedules and airline notifications throughout today as the operational picture evolves.
