Over 4,500 flights cancelled by Christmas day as Omicron hits holiday travel
Over 4,500 flights were cancelled around the world by Saturday and thousands more were delayed as the highly infectious Omicron variant disrupted holiday travel, according to tracking website Flightaware.
One route, however, was thankfully not affected: Santa was on track delivering presents to children across the globe, air defence officials assured US President Joe Biden.
According to Flightaware.com, at least 2,000 flights were cancelled worldwide on Christmas Day, including roughly 700 originating from or headed to US airports, with more than 1,500 delays as of 0720 GMT.
On Friday, there were around 2,400 cancellations and almost 11,000 delays. The site also reported over 600 cancellations for Sunday.
Pilots, flight attendants and other staff have been calling in sick or having to quarantine after exposure to Covid, forcing Lufthansa, Delta, United Airlines and many other carriers to cancel flights during one of the year's peak travel periods.
Flightaware data showed United cancelled around 200 flights on both Friday and Saturday, or 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 on Friday.
"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 airline said, adding that it was working to rebook passengers.
Similarly, Delta cancelled at least 260 flights Saturday and around 170 on Friday, saying it has "exhausted all options and resources — including rerouting and substitutions of aircraft and crews to cover scheduled flying."
"We apologise to our customers for the delay in their holiday travel plans," the company said.
Eleven Alaska Airlines flights were axed, after employees said they were potentially exposed to Covid-19 and had to self-isolate in quarantine.
The cancellations added to the pandemic frustration for many Americans 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 around 480 flights or over 20 percent of it's flight plan, and Air China grounding 15 per cent of its total scheduled departures at around 0720 GMT Saturday.
According to estimates from the American Automobile Association, more than 109 million Americans were scheduled to travel by plane, train or automobile between Dec.23 and Jan.2, a 34 per cent increase since last year.
But most of those plans were made before the outbreak of the Omicron variant, which has become the dominant strain in the United States, overwhelming some hospitals and healthcare workers.
