Blizzard Flight Cancellations: Know Your Passenger Rights Under DOT Rules

A major winter storm on February 23, 2026, led to significant Irregular Operations (IROP) across the United States, with data from Cirium indicating that over 19% of all U.S. flights were canceled. This figure stands in stark contrast to the typical daily domestic cancellation rate of approximately 1%. Such large-scale disruptions underscore the critical importance for passengers to understand their rights and the operational procedures airlines implement during severe weather events.

Flight disruptions caused by weather can extend for days as airlines work to reset their networks, reposition aircraft, and get crews back into their scheduled rotations. While frustrating for travelers, airlines often engage in proactive cancellations ahead of major storms. This strategy is designed to prevent aircraft and personnel from being stranded at airports with severe weather, which ultimately facilitates a faster recovery of the entire flight network once conditions improve.

Passenger Rights During Weather Disruptions

Under regulations set by the U.S. Department of Transportation (DOT), passengers have specific entitlements when flights are disrupted, regardless of the cause. The most fundamental right concerns cancellations. According to the DOT, a consumer is entitled to a full cash refund if an airline cancels a flight for any reason and the passenger chooses not to accept an alternative flight. This rule applies even when the cancellation is due to weather, which is considered outside the airline's control.

For significant delays, passengers also have rights. The DOT defines a "significant delay" as three hours or more for domestic flights and six hours or more for international flights. If a flight is delayed by this duration and the passenger opts not to travel, they are also entitled to a full refund. These regulations are detailed on the DOT's official refunds information page.

It is crucial to distinguish between refund eligibility and compensation for amenities. While passengers are entitled to a refund for a canceled flight, airlines are not legally required to provide compensation such as meal vouchers or hotel accommodations for delays or cancellations caused by weather. These controllable-versus-uncontrollable distinctions are outlined in each airline's customer service plan, which can be compared on the DOT's Airline Customer Service Dashboard.

Airline Procedures and Recommendations

In advance of severe weather, most major U.S. airlines issue travel waivers. These waivers allow passengers with bookings to, from, or through affected airports to change their flights to a different day without incurring a change fee, even for restrictive basic economy tickets. This provides flexibility for travelers who wish to alter their plans to avoid the storm's peak impact.

According to Matas Cenys, head of product at Sailey, passengers should monitor their airline's mobile app closely. “If your flight is within 48 hours of the storm window, monitor your airline app closely," Cenys advises. "Enable notifications, and consider rebooking to the earliest departure before the weather peak or the first flights after it passes. Airlines often waive change fees during severe weather. Use those windows quickly.”

If a flight is canceled, passengers should contact the airline immediately through their app, website, or customer service phone number. While airport help desks are an option, they often experience long lines during major IROP events. When rebooking, airlines will typically place passengers on the next available flight at no additional cost.

The Broader Impact of Weather on Aviation

Weather remains the single largest factor in air travel disruptions. The Federal Aviation Administration (FAA), the U.S. agency regulating civil aviation, reports that weather accounts for over 75% of all flight delays. These delays, managed by Air Traffic Control (ATC) to ensure safety, have a significant economic impact. The FAA estimates that flight delays cost the U.S. economy $32.9 billion annually, a figure that includes airline operating costs and lost passenger time.

The increasing frequency of extreme weather events continues to challenge the resilience of the national aviation system. Proactive network management and clear communication with passengers are key strategies the industry uses to mitigate the operational and financial impact of inevitable weather-related disruptions.

Why This Matters

For passengers, understanding the difference between a legal right to a refund and an airline's customer service policy for amenities is critical for managing expectations during weather-related IROP. For the aviation industry, the rising impact of extreme weather events necessitates continued investment in predictive technologies and operational strategies to minimize network disruptions and expedite recovery, ensuring the safety and efficiency of the national airspace.
