Over 2,600 flights were canceled globally as of early Friday, including over 1,200 flights within the US or entering or departing it, according to a running tally on flight-tracking website FlightAware.com. There were over 4,600 global flight delays in total.
The Christmas holidays are typically a peak time for air travel, but the rapid spread of the highly transmissible Omicron variant has led to a sharp increase in Covid-19 infections, forcing airlines to cancel flights as pilots and crew need to be quarantined.
The sudden arrival of Omicron has brought record-setting case counts to countries around the world. Transportation agencies across the US are suspending or reducing service due to COVID-19 staff shortages as the Omicron variant surges nationwide.
On Thursday, for the second day in a row, the US had a record number of new reported cases based on the seven-day average, with more than 290,000 new infections reported each day, a Reuters tally showed, as US officials weigh the impact of the Omicron variant.
The state of New York, in particular, reported over 74,000 Covid-19 cases on Thursday from more than 336,000 tests at a 22% positivity rate, Governor Kathy Hochul said.
New York said last week it will sharply limit the number of people it allows in Times Square for its New Year’s Eve celebration. However, some critics have raised concerns over the celebrations going ahead at all, given the high positivity rate.
The rise in US Covid-19 cases has caused some companies, particularly in the energy sector, to change course from earlier plans to increase the number of employees working from their offices starting next week.
Chevron Corp was to start a full return to office from Jan 3 but told employees this week it was postponing the plans to an unspecified date.
US airline cabin crew, pilots and support staff are reluctant to work overtime during the holiday travel season despite offers of hefty financial incentives. Many workers fear contracting Covid-19 and do not welcome the prospect of dealing with unruly passengers, some airline unions have said.
In the months preceding the holidays, airlines were wooing employees to ensure solid staffing, after furloughing or laying off thousands over the last 18 months as the pandemic crippled the industry.
