The U.S. commercial aviation sector is facing one of its biggest operational challenges this winter with the arrival of Winter Storm Fern, a weather system threatening mass cancellations, widespread delays, and complex operational decisions for airlines and airports. According to industry estimates and meteorological authorities, the phenomenon could directly or indirectly impact up to 235 million people across a large part of the country.
The event combines heavy snow in the north, ice and freezing rain across broad areas of the central and eastern regions, and risks of power outages and tree damage in the Southeast—a scenario especially challenging for the continuity of air operations.
A Weather Front with Systemic Impact
According to AccuWeather, Fern will bring temperatures not seen in at least five years. Dan DePodwin, the company’s vice president of forecasting operations, was blunt: “This will likely result in thousands of flight cancellations between Saturday, Sunday, and Monday.”
U.S. airlines have already activated large-scale contingency plans, anticipating a domino effect across their networks.
Airlines Activate Waivers and Travel Alerts
The nation’s major airlines began issuing fee-free change policies, a clear sign of the expected magnitude of the impact:
American Airlines
The Fort Worth-based airline included 35 airports in its weather alert. Passengers with flights scheduled between January 24th and 27th can rebook without penalty.

Delta Air Lines
Based in Atlanta, Delta expanded its warning to 65 airports under the “Eastern North America Winter Storm” designation, allowing fee-free changes for travel from January 24th to 26th.
JetBlue Airways
The New York-based company listed 35 airports, with flexibility to modify itineraries for the same critical dates.
Southwest Airlines
Southwest included 46 airports in its advisory, enabling no-cost changes for flights between January 24th and 26th.
For industry executives, these figures reflect a cross-cutting impact on multiple hubs and operational bases, limiting options for a swift network recovery.
Airports in Contingency Mode
Airports also adjusted their operational protocols ahead of the storm’s advance:
- Ronald Reagan Washington National Airport issued a formal warning for significant snowfall, confirming that snow crews will be ready to treat runways and critical surfaces. The airport alerted passengers to potential delays and cancellations, urging them to check their flight status before traveling.
- At Piedmont Triad International Airport (North Carolina), Executive Director Kevin Baker confirmed the airport will remain open, though he acknowledged airlines might cancel flights due to the event’s systemic impacts.
- Dallas Love Field is actively monitoring surface temperatures and conducting runway friction tests, a key point for operational safety. Spokesperson Lauren Rounds confirmed that, in the event of large-scale disruptions, safe areas within the terminal will be set up with cots, blankets, and refreshments if needed.
- At Dallas/Fort Worth International Airport (DFW), the operational team is working in coordination with the National Weather Service, preparing to treat access roads, bridges, and critical areas to maintain the hub’s ground connectivity.
The travel app Hopper estimates that more than 15,000 flights could face delays and detected a 17% increase in the purchase of disruption assistance services for this weekend.
For industry analysts, this data confirms a growing trend: passengers are anticipating operational risk and seeking coverage for increasingly frequent and intense weather events.
For the aviation industry, Fern is a test of operational resilience, interagency coordination, and passenger expectation management. Yet another reminder that in winter, weather remains one of the most decisive factors in the airline business.
