“The nationwide spike in Omicron cases this week has had a direct impact on our flight crews and the people who run our operation,” United said in a statement on Thursday. “As a result, we’ve unfortunately had to cancel some flights and are notifying impacted customers in advance of them coming to the airport.”
United said it was trying to rebook travelers as possible.
U.S. airline executives this week asked the Centers for Disease Control and Prevention officials to loosen quarantine guidelines for fully vaccinated individuals who test positive for Covid to five days from the current 10, citing potential staffing shortages and flight disruptions. The CDC loosened its guidelines for healthcare workers on Thursday.
United canceled more than 170 mainline flights scheduled for Friday, about 9% of its schedule, according to flight-tracking site FlightAware.
Delta canceled more than 131 flights, or 6% of its Friday’s schedule, citing bad weather in the Salt Lake City and Seattle area, two of its hubs, and the impact of the fast-spreading omicron variant. Delta cancelled more than 90 Saturday flights while United canceled more than 50. Jet Blue canceled more than 50 flights on Friday.
“Delta teams have exhausted all options and resources — including rerouting and substitutions of aircraft and crews to cover scheduled flying — before canceling around 90 flights for Friday,” the airline said in a statement. “We apologize to our customers for the delay in their holiday travel plans. Delta people are working hard to get them to where they need to be as quickly and as safely as possible on the next available flight.”
More than 90% of Delta employees and more than 96% of United’s U.S. staff are vaccinated, the airlines have said.
Delta and United’s flight disruptions are far fewer than the mass cancellations some airline customers faced this summer and fall as carriers including American and Southwest grappled with staffing shortages and bad weather. Both of those airlines offered staff compensation to work peak holiday trips and meet attendance goals. Southwest had just one cancellation on Friday and American had eight, according to FlightAware.
Airline executives in recent weeks have said they expect some of the busiest days since the pandemic began over the year-end holidays, despite the increase in Covid cases around the country.
