Delta Cancels Hundreds of Flights Amid Post-Christmas Winter Storm

Delta Air Lines canceled hundreds of flights on December 26, 2025, citing a severe winter storm impacting the U.S. Northeast.

As of early afternoon, Delta canceled 186 mainline flights. The carrier also reported hundreds of additional delays. Its regional operator, Endeavor, registered significant cancellations.

The disruptions contribute to a broader air travel meltdown, with U.S. airlines canceling over a thousand total flights. The major winter storm creates hazardous conditions across the Great Lakes, Mid-Atlantic, and New England regions.

In response, Delta and other major carriers issued travel waivers. These waivers allow affected passengers to rebook without incurring change fees.
