FAA Daily Air Traffic Report, September 1, 2025
Scattered thunderstorms and Labor Day volume are today's twin disruptors, concentrating along the Gulf Coast, across Central and South Florida, and over oceanic tracks east of New York. The FAA Daily Air Traffic Report highlights possible ground stops or delay programs at Florida hubs, Dallas and Houston, and select Northeast and Mountain West airports, with reroutes active between the Northeast and Florida. Oceanic route L455 is closed into the afternoon, and a VIP movement TFR will briefly reshape flows near Washington, D.C., later today.
Key Points
- Why it matters: Storms and holiday crowds raise misconnect risk and mid-day delays across multiple hubs.
- Travel impact: GDPs or ground stops are possible at MCO, TPA, MIA, FLL, PBI, DFW, DAL, IAH, and HOU.
- What's next: NE-to-Florida partial reroute through 1100 a.m. to 1200 p.m. CT, Ski Country FCA 1000 a.m. to 300 p.m. CT.
- Oceanic L455 closed until about 1:00 p.m. CT, alternate tracks in use.
- VIP TFR mid-afternoon near Cincinnati and Washington, D.C., expect minor procedural tweaks.
Snapshot
The FAA's midday plan, effective September 1, calls thunderstorms along the Mexico boundary, the Gulf Coast within Houston Center airspace, and from the Jacksonville and Miami boundary south into the Caribbean. Florida hubs, including Orlando International Airport (MCO), Tampa International Airport (TPA), Miami International Airport (MIA), Fort Lauderdale-Hollywood International Airport (FLL), and Palm Beach International Airport (PBI), are on watch for ground stops or ground delay programs beginning late morning to early afternoon Central time. Dallas Fort Worth International Airport (DFW), Dallas Love Field (DAL), George Bush Intercontinental Airport (IAH), and William P. Hobby Airport (HOU) follow around midday to early afternoon. Low ceilings may slow San Diego International Airport (SAN), Los Angeles International Airport (LAX), Seattle-Tacoma International Airport (SEA), and San Francisco International Airport (SFO) early.
Background
The Air Traffic Control System Command Center (ATCSCC) publishes the FAA Daily Air Traffic Report as an operational plan, then updates it after strategic planning webinars. On September 1, the plan combines convection-driven tactics in Florida and the Gulf with crowd-driven initiatives at Colorado mountain fields and select Northeast airports. Travelers can compare today's pattern with recent days, such as our FAA Daily Air Traffic Report, August 31, 2025, to see how reroutes and delay programs shift as storms pulse and traffic peaks.

Latest Developments in the FAA Daily Air Traffic Report
Florida and Gulf thunderstorms drive terminal programs
Thunderstorms are the main constraint for Central and South Florida and across Houston's airspace. Ground stops or delay programs are possible after 1100 a.m. CT at Miami International Airport (MIA), Fort Lauderdale-Hollywood International Airport (FLL), and Palm Beach International Airport (PBI), after 1200 p.m. CT at Orlando International Airport (MCO) and Tampa International Airport (TPA), after 100 p.m. CT at George Bush Intercontinental Airport (IAH) and William P. Hobby Airport (HOU), and after 1100 a.m. CT at Dallas Fort Worth International Airport (DFW) and Dallas Love Field (DAL). Ronald Reagan Washington National Airport (DCA) and Teterboro Airport (TEB) carry afternoon watch windows, with gusty winds and volume likely to push minor spacing at times in the Northeast.
En route constraints, reroutes, and oceanic closures
Two tactical items frame the late morning. A partial Northeast-to-Florida route via J48 is active for planned departures 700 a.m. to 1100 a.m. CT, steering traffic around weather over Jacksonville Center. A Ski Country Flow Constrained Area is required 1000 a.m. to 300 p.m. CT to meter holiday peaks into Aspen/Pitkin County Airport (ASE), Eagle County Regional Airport (EGE), Rifle Garfield County Airport (RIL), Friedman Memorial Airport (SUN), and Jackson Hole Airport (JAC). Over the Atlantic, New York Oceanic advises that track L455 is closed due to thunderstorms until about 1:00 p.m. CT, with users expected to file alternates. Gulf route closures are probable into early evening.
Staffing, VIP TFRs, construction, and space operations
Staffing triggers remain in effect for the Philadelphia TRACON area and Chicago C90 until 1200 p.m. CT. A VIP movement is scheduled with a departure near Cincinnati/Northern Kentucky International Airport (CVG) around 300 p.m. CT and an arrival at Joint Base Andrews (ADW) near 4:00 p.m. CT, with associated temporary flight restrictions. Runway and taxiway projects include nightly closures at Philadelphia International Airport (PHL), taxiway work at Fort Lauderdale-Hollywood International Airport (FLL), a runway closure at William P. Hobby Airport (HOU), and ongoing work at Minneapolis-Saint Paul International Airport (MSP), LaGuardia Airport (LGA), John F. Kennedy International Airport (JFK), O'Hare International Airport (ORD), Indianapolis International Airport (IND), George Bush Intercontinental Airport (IAH), San Francisco International Airport (SFO), and San Diego International Airport (SAN). SpaceX windows mid-week at Vandenberg and Cape Canaveral carry minimal NAS impact today.
Analysis
Today's plan blends familiar late-summer patterns. Florida convection, plus Gulf and Atlantic thunderstorms, narrows viable routes and compresses schedule recovery windows. The partial J48 reroute helps, but northeast-to-Florida flows will still see longer block times through late morning. Oceanic closures, such as L455, trim flexibility for eastbound departures from the Mid-Atlantic and Northeast, which can cascade into gate holds and EDCTs as crews wait for new clearances. The Ski Country FCA protects small-field operations where runway environments, terrain, and parking are tight, so travelers into Aspen, Eagle, Jackson, Sun Valley, and Rifle should expect metering and potential diversions during peak banks. Add in staffing triggers around Philadelphia and the Chicago TRACON, and the result is a classic holiday squeeze where minor disruptions stack quickly. To protect connections, travelers should prefer earlier departures, avoid tight layovers touching Florida or the Rockies this afternoon, and monitor airline apps for reroute-driven seat or gate changes that might not trigger email alerts. If your routing crosses the Gulf or Atlantic, pad for airborne holds or longer over-water tracks noted in the FAA Daily Air Traffic Report.
Final Thoughts
Holiday demand, summer storms, and a few strategic constraints are enough to ripple across hubs today. If your trip touches Central or South Florida, the Gulf Coast, Ski Country fields, or oceanic tracks, build in buffer time and consider moving to earlier flights where possible. Watch for late-day VIP TFR timing near Washington, D.C., and for lingering Gulf route limits through early evening. Keep the FAA Daily Air Traffic Report handy, and check for midday updates after the 8:15 a.m. CT planning webinar.
