Flight cancellations slow travelers at Logan Airport in Boston

A wave of flight cancellations on Monday continued to slow holiday travel in Boston and other cities.

The cancelled flights are due in part to a shortage of workers as COVID surges throughout the country, driven largely by the omicron variant.

More than 90 flights have been cancelled in or out of Logan International Airport since Sunday, according to flight tracker site FlightAware. Nationally, over 1,200 U.S. flights were cancelled Monday, including more 40 than flights to or from Boston.

Still, airline travel has mostly bounced back from the lows last year when many people stayed home or chose to drive. A Massachusetts Port Authority spokesperson said Logan has recorded about 25% fewer passengers so far this month, compared to the total for the full month of December 2019. About 3.4 million people traveled through Logan in December 2019.
