United Airlines Holdings Inc. is canceling dozens of flights over the holiday weekend, as a surge of COVID-19 cases impacts crews, and Delta Air Lines Inc. also cited the variant as a factor behind a number of cancellations.
At both airlines, the cancellations account for a relatively small share of planned flying. United has canceled about 131 flights scheduled for Friday, about 7% of its planned schedule, and about 28 that were slated for Sunday, according to FlightAware, a flight tracking site.
