The Federal Aviation Administration’s July 28 daily air traffic report said thunderstorms could delay flights in Charlotte (CLT (CLT)), Denver , Philadelphia and several Florida airports, including DJT, Fort Lauderdale (FLL (FLL)), Orlando (MCO (MCO)) and Mia (MIA)mi . The same outlook listed the New York-area airports Newark (EWR (EWR)), John F. Kennedy (JFK (JFK)) and LaGuardia (LGA (LGA)), along with Baltimore/Washington (BWI (BWI)), Ronald Reagan Washington National (DCA (DCA)) and Washington Dulles (IAD (IAD)) in the Washington, D.C. region.
The FAA also said low clouds may slow traffic in Seattle and San Francisco (SFO (SFO)), while high winds are expected in Las Vegas . The wording describes possible operational effects rather than confirming that every listed airport is already experiencing a delay. It also does not announce cancellations for individual flights. Conditions and traffic-management measures may change with weather forecasts and other factors beyond the agency’s control.
The agency said its daily report provides a reasonable expectation of impacts to normal air traffic operations, including arrival or departure delays, ground stops and airport closures. The information is intended for air traffic operations planning. The FAA separately advised travelers to check with their air carrier for flight-specific delay information and directed readers seeking current operational information to its live air traffic status service. The daily report should therefore be read as a system-level planning snapshot, not as the final status of a particular itinerary.
A separate FAA announcement from June 22 provides earlier context on how the agency plans to improve traffic-flow management through Strategic Management of Airspace, Routes, and Trajectories, known as SMART. According to the FAA, SMART will continuously analyze airline schedules, weather, airport capacity, airspace conditions and operational constraints to predict traffic flows and identify potential conflicts before they occur. The shared view is intended to help the FAA, airlines and operators coordinate routes and departure and arrival times.
The FAA said initial operations using SMART are planned for fall 2026. The June modernization announcement and the July 28 daily report address different time horizons: the former describes a future traffic-management tool, while the latter records weather-related operational risks for that day. The FAA did not state that the July 28 report was produced by SMART.
