Hundreds of travelers were left stranded at the Washington DC's airports on Monday after dozens of flights were canceled or delayed amid the surge of the infection of the Omicron variant of the Coronavirus.

Passengers were seen waiting for updates for their flights at Reagan National Airport in Arlington, Virginia, near Washington DC.

The Omicron variant has quickly become the dominant form of the virus in the United States in recent weeks, accounting for the vast majority of new cases in the country and driving a spike in new infections.

More than 1,000 flights were canceled by US airlines on Sunday as crews were grounded due to an outbreak of Covid-19, which caused misery for thousands of Christmas travelers.

A total of 997 flights were scrapped on Christmas Day and nearly 700 on Christmas Eve. Thousands more were delayed.
