FAA Daily Air Traffic Report: September 11, 2025
A busy convective pattern in Florida and the Rockies, paired with low ceilings on the West Coast, shapes the FAA's plan for September 11, 2025. The Air Traffic Control System Command Center signals possible ground delay programs for Boston, San Francisco, Seattle, Washington National, LaGuardia, Orlando, Tampa, Miami, Fort Lauderdale, and Denver, with additional reroutes tied to military activity and Gulf closures. SpaceX launch windows later in the week appear in the planning deck.
Key Points
- Why it matters: Expect pushback holds, metering, and missed connections if ground delay programs activate.
- Travel impact: Florida hubs and Denver face thunderstorms, while Seattle and San Francisco contend with low ceilings.
- What's next: Midday planning updates will refine initiatives, including any airspace flow program needs.
- VIP movements and special-use airspace may prompt brief reroutes near the Mid-Atlantic and Gulf.
- Watch NAS Status for live ground stops or program activations through the day.
Snapshot
Terminal risks center on afternoon storms in South and Central Florida and around Denver International Airport (DEN). Low ceilings are in play at Seattle-Tacoma International Airport (SEA) and San Francisco International Airport (SFO), where morning inbound rates may be trimmed. The Command Center flags potential ground delay programs at Ronald Reagan Washington National Airport (DCA), LaGuardia Airport (LGA), General Edward Lawrence Logan International Airport (BOS), SFO, SEA, Orlando International Airport (MCO), Tampa International Airport (TPA), Miami International Airport (MIA), and Fort Lauderdale-Hollywood International Airport (FLL). Expect capping, tunneling, and regional routes, plus Gulf route closures, if convection organizes. Planned SpaceX windows later this week could add short oceanic constraints, although they do not directly affect most commercial flows.
Background
The FAA Daily Air Traffic Report outlines likely constraints and management tools, including a ground delay program that meters arrivals by assigning expect departure clearance times, and an airspace flow program that meters traffic through constrained en route sectors. These initiatives keep demand aligned with capacity during weather, runway work, or special-use airspace events. For historical context and trend lines, compare today's plan with recent coverage in FAA Daily Air Traffic Report: September 10, 2025 and FAA Daily Air Traffic Report: September 9, 2025.

Latest Developments
Florida storms and West Coast ceilings may trigger programs
The Operations Plan highlights thunderstorms around MIA, FLL, MCO, TPA, and DEN, with low ceilings at SEA and SFO. Terminal initiatives are listed as possible for DCA, SEA, LGA, SFO, BOS, MCO, TPA, MIA, FLL, and DEN on September 11, with Seattle and San Francisco specifically noted for morning low-ceiling impacts. The plan also lists LAS for wind risk. Travelers should expect gate holds and EDCTs if a ground delay program is issued, especially during afternoon peaks in Florida and the Northeast. Check airline alerts frequently, since metering can shift with storm intensity and ceiling lifts.
Reroutes around Florida and Gulf; special-use airspace active
En route notes call out potential regional routes, capping, and tunneling, with Gulf route closures marked as probable. Flow-constrained areas include Ohio Valley to Florida streams and South Florida arrivals, with STAVE and Y-route advisories referenced. The plan also flags the Eglin water test area and oceanic transmitter maintenance, which can prompt minor re-routes. VIP movements appear on the board, and a Temporary Flight Restriction over New York spans September 10 to 11. SpaceX launch windows from Florida and California later this week are listed as primary and backup UTC windows, a routine factor for oceanic corridors.
Analysis
Operationally, today's risk splits three ways. First, Florida convection can stall arrivals into Orlando International Airport (MCO), Tampa International Airport (TPA), Miami International Airport (MIA), and Fort Lauderdale-Hollywood International Airport (FLL), which often triggers a ground delay program during the late-day push. If storms pulse, expect reroutes and escape routes for North-South flows. Second, low ceilings at Seattle-Tacoma International Airport (SEA) and San Francisco International Airport (SFO) reduce acceptance rates, increasing the likelihood of a program if the marine layer lingers. Third, Denver International Airport (DEN) sits on the boundary of afternoon buildups that can create short airborne holding or departure metering.
For you, the practical playbook is simple. Build extra connection time on itineraries touching these hubs, and monitor your reservation for an EDCT if a ground delay program posts. If your carrier offers same-day changes without a fare difference, moving to a morning departure can dodge Florida storms. For transcons to or from SFO and SEA, pad arrival buffers for meetings or last-mile ground transfers. Remember that an airspace flow program may be added later if storms organize along common corridors, even if none are active early. NAS Status is the fastest signal of a newly issued ground stop or ground delay program, often appearing before push notifications from airlines.
Final Thoughts
Weather and low ceilings dominate the September 11 outlook, but the day remains manageable with preparation. Florida hubs and Denver are the main thunderstorm risks, while Seattle and San Francisco hinge on ceiling improvements. Keep an eye on NAS Status, watch for EDCTs, and consider moving to earlier departures if your itinerary is tight. If you are connecting through multiple risk nodes, build buffers and download your airline's app for gate-change alerts. With a little flexibility, you can stay ahead of any metering that emerges from the FAA Daily Air Traffic Report.
