446 US Flights Canceled Today — Seattle, Chicago, New York Hit Hardest

Thousands of passengers across the United States are stranded at terminals today after a convergence of extreme weather systems triggered 446 flight cancellations and 4,910 delays nationwide, according to FlightAware data. Seattle, Chicago, Charlotte, New York, and Cleveland are among the worst-affected cities, with PSA Airlines, Delta, United, Southwest, and Alaska all reporting widespread disruptions caused by snow, ice, high winds, and a concurrent equipment outage at Chicago O'Hare.

The disruptions span virtually every major US hub, from Honolulu to Boston, making this one of the most geographically extensive single-day disruption events of 2026 so far.

What Is Causing the Chaos: A Multi-System Weather Assault

The scale of today's disruption reflects the unusual coincidence of several distinct weather events hitting the country simultaneously.

Polar Vortex in the Midwest and East: Frigid air from a polar vortex is driving temperatures in Minneapolis and Chicago to lows near 0°F (-18°C) and single digits. Chicago O'Hare is experiencing both equipment outage-related ground delays and wind-driven departure delays simultaneously.

Bomb Cyclone and Great Lakes Snowstorms: Two storm systems are targeting the northern Great Lakes and northern US tier. The second storm is forecast to intensify into a bomb cyclone — an unusually powerful event for a land-based system — bringing 3 to 4 feet (1 to 1.2 meters) of snow accumulation to parts of the region.

Snow and Ice at Seattle-Tacoma: SeaTac is under a ground stop and ground delay program due to snow and icy conditions, which has pushed the airport to 78 cancellations — the highest of any single US airport today.

Triple-Digit Heat Dome in the Southwest: A heat dome is parked over the Southwest, with Phoenix, Arizona, projected to reach 107°F (42°C). At this early point in the year, passengers are not acclimatized to such heat, and operational stress at Southwest-heavy airports is elevated.

Flooding in Hawaii: An atmospheric river is driving persistent heavy rain and flash flooding across Oahu. Daniel K. Inouye International Airport (HNL) has recorded 22 cancellations and 36 delays, with a flash flood warning in effect.

High Winds and Wildfire Risk in Texas: Winds reaching up to 60 mph (97 km/h) are sweeping through Texas, Kansas, Oklahoma, and parts of the Gulf Coast, elevating wildfire risk and affecting airport operations in the region.

Alaska Cold Wave: Temperatures in Alaska are running approximately 30 degrees colder than seasonal norms, compounding operational challenges at Alaskan airports.

The Worst-Hit US Airports Today

Seattle-Tacoma (SEA)	78	340
Chicago O'Hare (ORD)	28	1,118
LaGuardia (LGA)	37	176
Reagan National (DCA)	32	172
Detroit Metro (DTW)	25	239
John F. Kennedy (JFK)	16	203
Charlotte Douglas (CLT)	18	203
Newark Liberty (EWR)	22	138
Daniel K. Inouye / Honolulu (HNL)	22	36
Billings Logan (BIL)	19	4
Minneapolis St. Paul (MSP)	20	109

Houston Bush (IAH)	9	73
Denver (DEN)	7	98
Atlanta Hartsfield-Jackson (ATL)	9	96
Phoenix Sky Harbor (PHX)	4	80
Miami (MIA)	5	86

Chicago O'Hare's 1,118 delays is the highest of any single airport in the country — more than three times the next closest figure — driven by the combination of equipment outage ground delays and wind-related departure holds.

Airlines Taking the Biggest Hit

Airline	Cancellations	Delays
PSA Airlines	50	156
SkyWest	46	411
Endeavor Air (DAL)	39	188
Delta Air Lines	31	372
Alaska Airlines	24	186
Republic	22	237
Hawaiian Airlines	22	19
United Airlines	9	455
Horizon (ASA)	13	45
Frontier	7	58
Southwest Airlines	4	568
American Airlines	1	563
Envoy Air	3	259
JetBlue	4	173
Piedmont	3	93
GoJet	3	91

American Airlines' 563 delays and Southwest's 568 delays on minimal cancellations confirm that both carriers are managing widespread network disruption through schedule holds rather than outright cancellations, which typically means longer waits rather than fully abandoned flights.

What Affected Passengers Should Do Now

Check status now, not at the airport. All major carriers offer real-time flight status through their apps and websites. Seattle and Chicago situations in particular are volatile — status is changing hour by hour.

Rebook before queues form. Most airlines are offering waiver rebooking at no additional fee for weather-affected itineraries. Call or use the app immediately rather than waiting until you reach the airport desk.

Know your rights on cancellations. If your flight is canceled, the operating airline is obligated to offer rebooking on the next available flight. Meals and hotel accommodation may be provided depending on the carrier's policies and whether the delay qualifies as within the airline's control.

Pack essentials for potential overnight delays. With bomb cyclone conditions developing in the Great Lakes region, some disruptions may extend overnight. Carry medications, chargers, and a change of clothes in your carry-on.

Consider travel insurance for future bookings. For any upcoming travel during the remaining weeks of the northern winter or Southwest heat season, trip cancellation insurance that covers weather delays is now a practical necessity, not an optional add-on.

What This Means for the Coming Days

The bomb cyclone system in the Great Lakes is still developing, meaning disruptions at Chicago, Detroit, Minneapolis, Cleveland, and connecting airports are likely to extend into March 15. Seattle snow conditions are subject to rapid change — check SeaTac's FAA advisory status before heading to the airport.

Phoenix and Southwest operations face stress from the early heat dome through the weekend. Honolulu travelers should monitor the flash flood warning and confirm airport access routes before departure.
