Major carriers such as Delta, United and JetBlue have all blamed the omicron variant for causing staffing problems that ultimately lead to flight cancellations.
"The nationwide spike in Omicron cases has had a direct impact on our flight crews and the people who run our operation," a United Airlines spokesperson told FOX Business. "As a result, we’ve unfortunately had to cancel some flights and are notifying impacted customers in advance of them coming to the airport."
The carrier said it's "working hard to rebook as many people as possible."
Meanwhile, American Airlines said "the number of COVID-related sick calls is consistent with what we have seen over the past few days."
However, the airline noted that a winter storm in Chicago accounted for "a significant number of our mainline cancellations" on New Year's Day.
"It’s affecting both flights in and out of Chicago and other flight sequences for our crew," the airline said.
Flight delays and cancellations tied to staffing shortages have been a regular problem for the U.S. airline industry over the past year.
However, the latest disruptions come amid a time when the Transportation Security Administration (TSA) projected that travel volume will near pre-pandemic levels.
On Sunday, the TSA screened 2,049,604 people at airport checkpoints across the country, down slightly from 2,392,331 in 2019.
