Ammon News - In the United States, United Airlines and Delta Air Lines (DAL.N) on Thursday said they had each canceled dozens of Christmas Eve flights, as the spreading COVID-19 Omicron variant takes a toll on its flight crews and other workers.

Chicago-based United canceled 120 flights for Friday, while Atlanta-based Delta said it has canceled about 90. Both said they were working to contact passengers so they would not be stranded at airports.

"The nationwide spike in Omicron cases this week has had a direct impact on our flight crews and the people who run our operation. 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.
