Omicron hits weekend travel; Over 7,000 flights scrapped across the world

New York: More than 7,000 flights have been canceled worldwide over the Christmas weekend and thousands more delayed, a tracking website reported Sunday, as the highly infectious Omicron variant brings holiday hurt to millions.

Severe weather is compounding the travel chaos in the United States, with storms expected to wreak havoc on roadways in the country’s west, though they brought a white Christmas weekend to Seattle and parts of California. According to Flightaware.com, more than 2,000 flights were canceled on Sunday -- including more than 570 originating from, or headed to, US airports. More than 4,000 delays were reported.

Aircrew and ground staff have fallen sick or gone into quarantine after exposure to Covid, forcing Lufthansa, Delta, United Airlines, JetBlue, Alaska Airlines and other carriers to cancel flights during a peak travel period.

More than 2,800 flights were scrubbed around the globe on Saturday, including more than 990 originating from or headed to US airports, with over 8,500 delays. On Friday, there were around 2,400 cancellations and 11,000 delays.

"Help @united flight cancelled again. I want to get home for Christmas," one exasperated traveler from the US state of Vermont tweeted early Saturday. Flightaware data showed United canceled around 200 flights on Friday and nearly 250 Saturday -- about 10 percent of those that were scheduled.

"The nationwide spike in Omicron cases this week has had a direct impact on our flight crews and the people who run our operation," United said in a statement Friday. Delta scrapped 310 flights Saturday and over 100 more Sunday, saying it has "exhausted all options and resources."

"We apologise to our customers for the delay in their holiday travel plans," the company said. The cancellations added to the frustration for many people eager to reunite with their families over the holidays after last year’s Christmas was severely curtailed.

Chinese airlines accounted for the highest number of cancellations, with China Eastern scrapping more than 1,000 flights, over 20 percent of its flight plan, on Friday and Saturday -- and Air China grounding about 20 percent of its scheduled departures over the period.

The American Automobile Association estimated more than 109 million Americans would travel by plane, train or automobile between December 23 and January 2, a 34 percent increase over the last year.

But most of those plans were made before the detection of Omicron, which has become the dominant strain in the United States, overwhelming hospitals and healthcare workers. The state of New York reported a record 44,431 new daily positive Covid tests on Friday, as new cases surged nationwide.

Meanwhile, the Chinese city of Xi’an, where 13 million residents are currently confined to their homes, announced tightened restrictions on Sunday as the country recorded its biggest Covid-19 infection numbers in 21 months.

In a related development, top US pandemic advisor Anthony Fauci on Sunday acknowledged a Covid "testing problem" as the Omicron strain overwhelms the nation, and he vowed to make more tests available to Americans next month.

"One of the problems is that that’s not going to be totally available to everyone until we get to January, and there are still some issues now of people having trouble getting tested," Fauci told ABC talk show "This Week." "But we’re addressing the testing problem," he added, saying it should be corrected "very soon."
