U.S. airlines cancel over 1,000 flights due to COVID-19, weather

Since Friday, airlines have canceled more than 4,000 flights to, from or inside the U.S., with over 1,000 U.S. cancellations on Monday, according to FlightAware.

Flight cancellations that disrupted holiday travel, stretched into Monday as airlines called off more than 1,000 U.S. flights because crews were sick with COVID-19 during one of the year’s busiest travel periods, and storm fronts added to the havoc.

Flight delays and cancellations tied to staffing shortages have been common this year. Airlines encouraged workers to quit in 2020, when air travel collapsed, and carriers have struggled to make up ground this year, when air travel rebounded faster than almost anyone had expected. The arrival of the omicron variant only exacerbated the problem.

“During the pandemic we have seen experienced airline personnel leave the industry and not return across the globe,” said John Grant, senior analyst at travel industry research firm OAG. “Filling those skill gaps was already a challenge in the recovery before the latest variant.”

But airlines’ staffing levels are “irrelevant” when omicron is thrown into the mix, said Atmosphere Research Group travel industry analyst Henry Harteveldt. “We can’t blame the issues we’re seeing now on airlines not having enough employees to work. What we’re seeing happen is the employees who were available to work have come down with COVID.”

Since Friday, airlines have canceled more than 4,000 flights to, from or inside the U.S., according to FlightAware, which tracks flight cancellations.

Delta, United, JetBlue and American have blamed the coronavirus for staffing problems in the past several days. European and Australian airlines also canceled holiday-season flights because of infected staff, but weather and other factors played a role as well.

Winter weather in the Pacific Northwest led to nearly 250 flight cancellations to or from Seattle on Sunday, according to Alaska Airlines, which expected more than 100 flight cancellations Monday. But the airline said sick crews were no longer a factor.
