United and Delta Airlines have canceled more than 200 Christmas Eve flights.
In a statement Thursday, when the cancellations first began, United Airlines blamed the cancellations on staffing shortages due to COVID-19.
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. We’re sorry for the disruption and are working hard to rebook as many people as possible and get them on their way for the holidays.
Delta Airlines issued a similar statement to ABC News, saying the company has "exhausted all options and resources."
