New York (CNN Business) -- More than 2,800 flights have been canceled this Monday around the world due to the advancement of the omicron variant of the coronavirus.

Worldwide, airlines canceled more than 6,000 flights on Christmas Eve, Christmas and the day after Christmas. In the United States, more than 1,200 flights were canceled and more than 5,000 were delayed on Sunday as staff and crews were absent due to illness.
