NEW YORK: Commercial airlines around the world cancelled more than 4,500 flights over the Christmas weekend, as a mounting wave of Covid-19 infections driven by the Omicron variant created greater uncertainty and misery for holiday travellers.
Airline carriers globally scrapped at least 2,401 flights last Friday, which fell on Christmas Eve and is typically a heavy day for air travel, according to a running tally on the flight-tracking website FlightAware.com.
