Adding to travellers’ woes, heavy snow has hit the central US.
From the US cancellations, more than 1,000 are from Chicago’s O’Hare and Midway airports.
“Today’s cancellations are driven by Omicron staffing and weather-related issues. We did pre-cancel flights in anticipation of inclement weather. We’ve been contacting passengers early if their flights are cancelled to give them time to rebook or make other plans,” United Airlines said in a statement.
Sunday, when many people often return home from their Christmas holidays, is likely to bring further disruption, with more snow and heavy winds forecast.
“It’s too long and there’s no space to spend the time, get something to eat, it’s a long time here,” one traveller stuck at O’Hara airport told ABC news in Chicago.
