NASHVILLE—More than 1 million Americans spent Jan. 25 in the dark as a severe winter storm shut off power across the South and prompted airlines to cancel nearly 11,000 U.S. flights.
The most affected airports were Charlotte Douglas International Airport in North Carolina, Hartsfield-Jackson International Airport in Atlanta, and all three of the New York area airports—LaGuardia Airport, Newark Liberty Airport, and John F Kennedy International Airport, according to flight tracker FlyAware.
