- The FAA warned Tuesday that Atlanta, San Francisco, New York JFK, Nashville, and Memphis could face air traffic controls, with storms and construction tightening available U.S. airspace.
- On Monday, FlightAware tracked 7,198 delays and 620 canceled flights either within the U.S., coming in, or departing.
- Pressure mounted at Chicago O’Hare, which logged 1,242 delays and 491 cancellations Monday.
U.S. air passengers ran into more disruption Tuesday, with the Federal Aviation Administration flagging possible ground stops or delays at key airports. The move stretched out the storm and construction crunch that slammed Chicago O’Hare just the day before.
This isn’t limited to a single airport anymore. The FAA’s Tuesday operations plan pointed to thunderstorms expected near Atlanta, Nashville, and Memphis. Meanwhile, San Francisco, Seattle, Denver, and New York JFK continued to wrestle with low ceilings, runway projects, and ongoing traffic restrictions. A ground stop pauses departures still on the ground, while ground delay programs bump flights to later slots, stretching out arrivals.
Delays don’t just stick to one airport—they ripple quickly. A hold-up in Chicago might strand crews in Dallas, cause missed connections in Atlanta, or jam up gates in New York. According to FlightAware, there were 7,198 delays and 620 cancellations tied to U.S. flights on Monday, within a global total of 20,717 delayed flights for the day.
The system hadn’t collapsed early Tuesday, though it was under pressure. FlightAware logged 608 delays and 120 cancellations for U.S. flights—departures, arrivals, and domestic runs all included.
FlightAware data showed 58 delays and 85 cancellations at Chicago O’Hare early Tuesday, after a busier Monday. Atlanta reported 56 delays with four cancellations, while JFK saw 22 delays and just one cancellation.
The setup took shape late Monday. The FAA issued a ground delay program at O’Hare, citing traffic restrictions for inbound Chicago flights due to thunderstorms. Earlier, flights around Dallas-Fort Worth faced stops as storms swept through Texas. Later, the agency listed delay programs for Seattle and San Francisco, this time because of construction. Thunderstorms prompted similar measures in Memphis and Louisville.
O’Hare bore the brunt, logging 1,242 delays and 491 canceled flights Monday, according to FlightAware. Atlanta—Delta’s main hub and the globe’s top passenger airport—saw 432 flights delayed, eight scrapped. Over at New York JFK, 146 delays and just two cancellations were tallied.
Delta’s network leans hard on Atlanta. Over in Dallas-Fort Worth, American Airlines runs its biggest hub, pushing out more than 900 flights on peak days. Chicago? It’s split: American controls O’Hare, Southwest dominates at Midway. United runs about 50% of San Francisco’s passengers, while Alaska has around a tenth—so local rules there hit both.
American’s CEO Robert Isom has already pointed to O’Hare as a vulnerable spot. Last week, he warned that without federal help on congestion, the airport could be “in a delay program for the very first flight of the day.” Isom also said American plans to defend its Chicago hub against United.

San Francisco’s situation is a different story. The FAA has slashed the number of permitted landings there, citing runway repaving and a pause on specific side-by-side approaches. Hourly arrival caps dropped to 36 from the previous 54. That shift puts about 25% of inbound flights at risk of delays of 30 minutes or more, according to the airport.
Capacity comes with its share of politics. Transportation Secretary Sean Duffy has advocated for air-traffic control modernization funding, arguing airlines at times book more flights than airports can realistically process, and pointing to software upgrades as a way to scatter flights with “way less disruption.” Reuters
The plan comes with tradeoffs. Storms that fizzle or move could leave some restrictions unused. But throw in bad weather, SFO construction, JFK taxiway projects, and late arrivals from Monday, and cancellations can pile up fast as planes and crews lose their place in the schedule.
U.S. airline refund policies don’t go as far as many passengers think. The Transportation Department’s rules only guarantee a refund if the airline cancels or substantially delays a flight and the passenger opts out. Otherwise, airlines typically aren’t required to compensate domestic travelers just because a flight was delayed or canceled.
