The National Weather Service advised against travel as the system stretched across much of the country. Travelers should check official channels for operational updates.

A large winter storm has caused extensive disruption across the U.S. air network, with more than 15,000 flights impacted. As of early Saturday morning, at approximately 5:40 a.m., FlightAware reported nearly 10,000 cancellations scheduled through Monday, along with an additional 5,000 flights experiencing delays.

Several major carriers reported significant operational impacts. American Airlines recorded 822 cancellations and 30 delays on Saturday. Southwest Airlines reported 571 cancellations and 33 delays. Delta Air Lines logged 165 cancellations and 33 delays, while United Airlines reported 150 cancellations and 45 delays.

According to the Federal Aviation Administration, multiple airports experienced temporary closures due to the storm. These included Harry Reid International Airport in Las Vegas, John Wayne Airport in Orange County, and San Diego International Airport. Air traffic professionals and weather teams have been engaged in snow removal and aircraft de-icing to keep operations moving where possible. The FAA advised travelers to monitor its official channels for real-time updates on airport status.

The weather system spans roughly 2,300 miles and is affecting areas from New Mexico to Maine. With a large portion of the country under winter weather alerts, the National Weather Service has advised people to avoid travel where feasible.

Passengers booked to travel during this period should be aware of potential schedule changes, including day-of delays and cancellations. Where airports are open, knock-on effects may still lead to irregular operations as carriers and airports address weather-related constraints and recover schedules.
