On the eve of Reagan National’s unprecedented Independence Day shutdown, three of the country’s busiest airports have independently buckled today — and none of it is connected to tomorrow’s planned closure.
Chicago O’Hare International Airport has recorded 326 delayed flights and 11 cancellations today, with United Airlines absorbing the largest share of delays and Jazz (Air Canada Express) accounting for the most cancellations. LaGuardia Airport in New York is under an active FAA Ground Program, triggered by high winds combined with localized airspace holds tied to rehearsal flights for tomorrow’s Salute to America 250 commemoration — 117 flights delayed, 9 cancelled, with average arrival delays of 62 minutes and tarmac waits stretching as long as 141 minutes. San Francisco International Airport has added a further 94 delays and 4 cancellations, led by United Airlines’ 63 delayed departures.
This is Day 94 of the ongoing US aviation crisis that began April 1 — and it lands directly on the eve of tomorrow’s Reagan National closure, when the airport shuts completely from noon to 7PM for the 250th anniversary “Salute to America” event, an unprecedented step that will ripple into Boston, JFK, LaGuardia, Newark, Philadelphia, and BWI. Today’s disruption at LaGuardia in particular appears to be an early preview of exactly that ripple effect, a full day before the official closure window even begins.

There’s an important distinction to make today: none of the three major disruptions — Chicago, LaGuardia, or San Francisco — are directly caused by tomorrow’s Reagan National closure. That event hasn’t even started yet. What’s happening today is the ordinary summer disruption engine — weather, airspace congestion, and hub saturation — running at full intensity on the single busiest travel day of the year, one day before an additional, deliberate layer of disruption gets added on top of it at six more East Coast airports.
Chicago O’Hare’s 326 delays represent one of its worst single-day totals this crisis period, driven primarily by United Airlines’ hub congestion — when O’Hare backs up, it doesn’t stay contained to Illinois. Today’s backlog has already rippled into Toronto Pearson, Dallas/Fort Worth, Boston Logan, Cleveland-Hopkins, and Minneapolis-St Paul, five airports whose incoming O’Hare connections arrived late or were cancelled outright.
LaGuardia’s situation is the most operationally distinct: an FAA-mandated Ground Program specifically triggered by the combination of high wind velocity and localized airspace holds connected to rehearsal and positioning flights ahead of tomorrow’s Salute to America festivities — including the Harbor Sail 4th 250 tall-ship flotilla and associated military flyover rehearsals affecting JFK, LaGuardia, and Newark approach paths. In effect, the 250th anniversary disruption many travellers were bracing for tomorrow has already started leaking into today’s schedule.
Chicago O’Hare International Airport recorded 326 delayed flights and 11 cancellations today. United Airlines, for which O’Hare is a primary hub, recorded the highest number of delayed flights of any carrier operating there. Jazz, Air Canada’s regional subsidiary, accounted for the largest share of cancellations, disproportionately affecting passengers on regional Canadian connections. American Airlines also reported a substantial number of delays, though its cancellation count remained limited. Delta Air Lines recorded both delays and at least one cancellation. Other carriers reporting disruption included Contour Airlines, SkyWest, Air Canada mainline, Alaska Airlines, and Lufthansa.
Because O’Hare functions as one of the country’s primary connecting hubs, today’s backlog cascaded into five other major airports: Toronto Pearson, Dallas/Fort Worth, Boston Logan, Cleveland-Hopkins, and Minneapolis-St Paul all recorded knock-on disruption tied to delayed or cancelled O’Hare-originating aircraft.
LaGuardia recorded 117 delays and 9 cancellations today under an active FAA Ground Program, implemented to manage reduced runway capacity caused by high winds and localized airspace restrictions connected to rehearsal activity ahead of tomorrow’s 250th anniversary commemoration. Average arrival delays reached 62 minutes, with some aircraft facing tarmac waits as long as 141 minutes.
LaGuardia’s intersecting-runway layout and its position within dense Northeast airspace make it especially sensitive to exactly this kind of combined wind-and-airspace-restriction event — a single hold can ripple across the entire regional network within minutes.
The New York–Toronto corridor absorbed the heaviest impact of any international route today: inbound flights from Toronto Pearson recorded 2 cancellations and 1 delay, while inbound flights from Toronto City Centre saw 1 cancellation and 3 delays — a 75% delay rate on that route alone. Outbound LaGuardia-to-Toronto-Pearson services fared similarly badly, with 3 cancellations and 2 delays. Jazz Aviation and Endeavor Air absorbed the bulk of today’s cancellations, while mainline carriers largely avoided outright cancellations in favor of absorbing delays. Miami and Orlando-bound routes also saw elevated congestion, with delay rates reaching as high as 33% on some Florida services.
San Francisco recorded 94 delays and 4 cancellations today. United Airlines accounted for the largest share by far, with 63 delayed flights, reflecting significant gate and taxiway congestion that dispatchers attributed to constrained gate utilization. Southwest Airlines reported 25 delays and 1 cancellation, affecting West Coast and Southwest regional corridors. Air Canada recorded 6 delays and 1 cancellation, affecting transborder connections to Toronto, Vancouver, Calgary, Edmonton, and Montreal. KLM Royal Dutch Airlines recorded a single cancellation on its transatlantic route, with no reported delays.
As covered in our full 250th anniversary airspace guide, Reagan National Airport shuts down completely from noon to 7PM tomorrow, July 4, for the Salute to America National Special Security Event, with related airspace restrictions extending into Boston, JFK, LaGuardia, Newark, Philadelphia, and BWI. American, Delta, United, and Southwest have active rebooking waivers covering travel scheduled July 3–5 for tickets purchased by June 17. If you’re flying through any of these seven airports over the holiday weekend and haven’t checked your airline’s waiver terms yet, today is the last full day to do so before the closure begins.
Chicago O’Hare: Today’s delays are hub-congestion driven, which can sometimes qualify as controllable depending on the airline’s specific stated reason. Ask the gate agent for the cause in writing before assuming either way.
LaGuardia: Today’s FAA Ground Program was triggered by weather (high winds) combined with airspace restrictions tied to a federal event — both are very likely to be classified as outside airline control, making cash compensation unlikely.
San Francisco: United’s 63 delays reflect gate/taxiway congestion, a pattern that can sometimes be classified as controllable if tied to inadequate staffing or scheduling. Again, request the specific cause in writing.
Regardless of cause, any cancelled flight today entitles you to a full refund to your original payment method if you decline rebooking. This applies at all three airports.
Airlines must get you to your final destination. Given how compressed rebooking inventory will be ahead of the July 4 weekend, ask about rebooking on partner or competing carriers if your own airline’s next available flight is unreasonably delayed.
Step 1: Get the specific stated cause in writing from your airline. Step 2: File directly with the airline first. Step 3: Escalate to airconsumer.dot.gov if unresolved. Step 4: For card purchases, consider a chargeback if a refund isn’t processed within 7 business days.
