United Airlines has also been canceling some of its flights. “The nationwide spike in omicron cases 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,” Chicago-based United said in a statement, adding that it is working to rebook as many people as possible “and get them on their way for the holidays.”
In addition to the impact of COVID-19 on flight crews, Delta also had storms through its hubs in Seattle and Salt Lake City, and issued waivers allowing flight changes without additional costs for flights to, from or through those cities.
The flight cancellations come after Delta CEO Ed Bastian earlier this week raised concerns about the impact of the variant on the airline’s workforce and operations, saying the surge “may exacerbate shortages and create significant disruptions.” In a letter to Rochelle Walensky, director of the Centers for Disease Control and Prevention, Bastian asked the CDC to reconsider a guideline for 10 days of isolation for COVID-19 infections in vaccinated people, and proposed a shorter isolation period.
