A winter storm that hit the mid-Atlantic on Monday combined with pandemic-caused shortages of airline workers pushed flight cancellations to a holiday-season high.
More than 3,000 U.S. flights and about 4,800 worldwide were canceled by late afternoon Monday on the East Coast, according to tracking service FlightAware. Another 13,000 flights were delayed, including more than 6,000 in the United Staes.
