Passengers traveling through U.S. airports faced schedule changes Monday morning, with FlightAware figures cited in the original report showing more than 1,420 delays and 65 cancellations by 10 a.m. EST.

Globally, the same snapshot recorded more than 13,000 delayed flights and 507 cancellations. These figures reflect conditions at the time of reporting, not final totals for the day.

What was behind the disruptions?

The Federal Aviation Administration flagged low clouds at San Francisco as a potential source of flight disruptions. According to the supplied report, no other FAA alerts were listed at 10 a.m.

That information does not establish a single cause for the delays nationwide. The report did not provide a broader breakdown of why individual flights were affected.

What travelers can do when plans change

For passengers facing disruption, checking the airline’s website or app is a useful first step. Enabling notifications can help travelers track revised departure times, gate changes, and cancellations.

If a flight is canceled, explore rebooking options promptly—but review the full journey before accepting an alternative. Consider connection time, arrival time, and the possibility of an overnight stop, rather than focusing only on the earliest available departure.

Travel speaker Eryn Gordon, speaking to Advance Local, advised passengers to approach cancellations as a planning problem. Her recommendations included saving a screenshot of the airline’s rebooking policy before traveling and checking whether a replacement itinerary could leave passengers separated from their luggage or waiting overnight at a connecting airport.

Keep essential belongings accessible in your carry-on, and review your airline’s refund and rebooking policies if the disruption continues.

A replacement flight is only part of the solution: the goal is to find a workable route all the way to your destination.
