More than 1100 flights were delayed or cancelled across US as major carriers including Spirit, Delta, American, United, JetBlue, Qatar Airways, Korean Air, Swiss, Virgin Atlantic, TAP Air Portugal, Emirates, Singapore Airlines, Air Canada, and LATAM faced widespread operational disruptions at key US airports—JFK, Miami, Houston, Newark, Chicago, Charlotte, and Atlanta—due to severe weather conditions and an emerging Pacific storm system. This sweeping wave of delays and cancellations was driven by thunderstorms across major metro areas, low visibility, and a growing tropical threat off the southern coast of Mexico, forcing airlines to adjust schedules, ground aircraft, and rebook passengers amid mounting travel chaos.

Chaos Hits US Airports as Airlines Scramble to Adapt

From coast to coast, airlines scrambled to keep up with turbulent skies and sudden weather shifts. In total, 1,094 delays and 32 cancellations were reported across just seven airports, bringing widespread travel headaches to thousands.

At Chicago O’Hare International Airport, delays reached a staggering 203, with American Airlines alone contributing to 50 delayed flights. United wasn’t far behind, facing 41 delays and 4 cancellations. Other affected airlines included Alaska, Delta, Spirit, GoJet, and Lufthansa. Notably, PSA Airlines saw 7 of its 18 flights delayed, reflecting a particularly rough day for regional operators.

Meanwhile, Charlotte Douglas International recorded 209 delays and 2 cancellations, largely driven by Piedmont Airlines (54 delays) and American Airlines (86 delays). PSA and Contour also reported high disruption rates.

Houston and Miami See Widespread Delays

Houston Bush Intercontinental logged 103 delays and 2 cancellations, with United Airlines alone accounting for 46 delays, reinforcing its central hub status. Other international carriers like Air Canada, All Nippon, Lufthansa, Emirates, and Avianca El Salvador also experienced smaller disruptions.

At Miami International Airport, travelers didn’t fare much better. The airport reported 124 delays and 1 cancellation, heavily skewed by American Airlines’ 76 delayed flights. International airlines such as British Airways, TAP Air Portugal, Turkish Airlines, and LATAM also saw significant percentages of their scheduled flights impacted.

Newark and JFK Also Hit Hard

Newark Liberty International Airport reported 79 delays and 8 cancellations, the highest cancellation count among the seven. United Airlines took the brunt with 38 delays and 6 cancellations, followed by Dreamjet, El Al, and Air India. GoJet, JetBlue, and TAP also experienced operational hiccups.

Just across the Hudson, New York JFK International Airport saw 113 delays and 6 cancellations. JetBlue suffered the worst of it with 47 delays, while Delta and American collectively had over 20 flights delayed or cancelled. International carriers like Qatar Airways, Virgin Atlantic, Swiss, and Singapore Airlines all reported service disruptions, particularly on transatlantic and intercontinental routes.

Boston and Atlanta Not Spared

In Boston Logan International Airport, 86 delays and 4 cancellations were reported. Local carrier Cape Air accounted for all four cancellations, while JetBlue, American Airlines, and Delta led the pack in delays. Qatar Airways, Japan Airlines, and Etihad also reported notable slowdowns.

Meanwhile, Hartsfield-Jackson Atlanta International Airport, one of the busiest in the world, experienced 177 delays and 4 cancellations. Delta Airlines had an outsized share with 112 delays, followed by Frontier and American. Even long-haul players like KLM, Turkish Airlines, and Ethiopian Airlines saw individual flights impacted by delays.

Why It’s Happening: Weather and a Brewing Storm

While some of the delays stemmed from ground operations and aircraft availability, the larger cause points to widespread weather instability. Thunderstorms, fluctuating wind patterns, and low visibility across several metro areas disrupted runway sequencing and aircraft turnaround.

To make matters worse, the National Hurricane Center (NHC) issued an alert about a developing system in the eastern Pacific Ocean, labeled EP95. Located off the coast of southern Mexico and Guatemala, the storm is slowly organizing and has an 80% chance of developing into a tropical depression or tropical storm within the next seven days. If it gains strength and moves toward North America, more disruptions could follow.

Passengers Urged to Monitor Flights

Airlines are urging travelers to check their flight status frequently, opt into text/email notifications, and arrive early at airports as the impact continues into the week. Carriers like Emirates, Qatar Airways, and United are offering free changes or rebooking options for affected passengers, while JetBlue and Spirit have taken to social media to notify travelers of high congestion at gates and check-in counters.
