Winter storm drives U.S. flight cancellations above 10,000, a pandemic-era peak

A powerful winter storm forced more than 10,000 U.S. flight cancellations on Sunday—the highest daily total since the start of the COVID-19 pandemic—driving widespread travel disruption as heavy snow, sleet and freezing rain sweep from the Southern Rockies to New England; over 1,800 flights were already canceled for Monday, with hubs like DFW and LaGuardia affected and airlines offering waivers as American, United and Delta cope with the impact.
