Volume-related congestion and operational issues are the primary causes

Thousands of air travelers across the United States are facing a major disruption day, with 223 cancellations and 4,272 delays recorded at airports from New York to Las Vegas.

Worst-Hit Airports Right Now

LaGuardia Airport (LGA) — Ground Delays of 142 Minutes

New York's LaGuardia Airport is the single most disrupted airport in the country today, recording 88 cancellations and 416 delays. Ground delays are averaging 142 minutes — more than two hours — attributed to unspecified "other" causes. Airlines most affected include Republic Airways, American Airlines, and Delta Air Lines.

Passengers transiting through LGA should assume their schedules are effectively void and rebook proactively rather than waiting at the gate.

Chicago O'Hare (ORD) and Orlando (MCO) Close Behind

Chicago O'Hare International has logged 20 cancellations and 229 delays — a significant operational burden for one of the world's busiest aviation hubs. Orlando International (MCO) is recording 5 cancellations and 194 delays, with departure waits averaging 30 minutes and climbing, driven by record passenger volumes.

Boston Logan (BOS) adds 16 cancellations and 126 delays, while JFK International registers 12 cancellations and 135 delays, further squeezing the already-congested New York metro airspace.

Las Vegas, Palm Beach, and Florida Airports

Harry Reid International (LAS) in Las Vegas is seeing 5 cancellations and 81 delays, with departure times stretching by an average of 15 minutes and expected to worsen. Palm Beach International (PBI) is among the more severely delayed smaller airports, with departures averaging 90 minutes late — attributed to operational halts. Southwest Florida International (RSW) adds 30-minute departure delays driven by passenger volume surges.

Which Airlines Are Most Affected?

Southwest Airlines — 661 Delays, 18 Cancellations

Southwest Airlines is absorbing the heaviest delay load of any US carrier today, with 661 delays and 18 cancellations across Las Vegas, Orlando, and Palm Beach. For a point-to-point carrier with no hub buffer, delays at one airport ripple immediately to the next destination.

American Airlines — 486 Delays, 14 Cancellations

American Airlines is dealing with 486 delays and 14 cancellations, with LaGuardia, Orlando, and Southwest Florida the worst-affected stations. Delta Air Lines follows with 305 delays and 7 cancellations, particularly at LaGuardia and Atlanta.

Republic Airways Tops Cancellations at 57

Republic Airways — operating regional feeder flights for American, United, and Delta — has the highest cancellation count today at 57, alongside 210 delays. Regional cancellations are especially painful as they strand passengers at smaller airports with fewer rebooking alternatives.

Airline	Cancelled	Delayed
Republic Airways	57	210
Spirit Airlines	27	188
Southwest Airlines	18	661
Endeavor Air (Delta)	18	208
SkyWest Airlines	15	261

What Affected Passengers Should Do Now

Check status before you leave home — with 4,272 delays recorded, your flight's departure time is almost certainly not what your boarding pass says. Check your airline app or FlightAware for live status.
Rebook now, not later — call center and counter queues are building fast. Airlines including Southwest, American, and United have self-service change tools on their apps. Use them before the crowds do.
Know your rights — US carriers are not legally required to compensate for delays caused by volume or operational issues (as opposed to weather). However, most major airlines will offer meal vouchers for delays over 3 hours and hotel accommodation for overnight cancellations — ask explicitly at the customer service desk.
Pack essentials in your carry-on — if your checked bag ends up on a later flight, you'll want medication, a phone charger, and a change of clothes easily accessible.
Watch for downstream effects — even if your outbound flight looks fine, a disrupted inbound aircraft could cancel or re-time your departure with little notice. Enable push notifications from your airline app.

Stay proactive, stay flexible — today's US flight disruptions are widespread but the system is working to clear the backlog.
