Two days after a major snowstorm wreaked havoc on travel plans in the Northeast, a perfect storm of factors has caused delays and cancellations affecting dozens of flights and hundreds of passengers at Logan Airport today.
Airlines already were saddled with a backlog of passengers trying to rebook trips that were cancelled because of snow Thursday and Friday. Today, icy conditions at other airports—including at Kennedy International Airport in New York City, where a taxiing plane slid off the runway—are causing delays that have rippled through the system to Boston.
The backlog will be difficult to clear, airlines said, because this weekend is a peak travel time for customers returning from holidays and there are few open seats on most flights.
