Roughly 55 million Americans are traveling this weekend. American Airlines is waiving change fees for flights routing through Boston and a number of other cities in the Northeast on Sunday and Monday. Boston is expecting close-to-record-breaking snowfall on Monday of up to six inches, CBS Boston reported.
Saturday saw more than 300 canceled flights, and cancellations have already started to roll in for Sunday, including eight at Chicago's O'Hare International Airport and six at New York's LaGuardia airport as of Sunday morning, according to FlightAware.
Some travelers took to social media to air their grievances. A Twitter user named Wendy Swetz elicited a reponse from United Airlines after posting this message on Sunday morning.
"United airline literally ruined our day- they cancel my sons flight without notice, missed his flight and now we are stranded today!! Unbelievably horrific service and terrible customer service! #unitedsucks #unitedairlines," Swetz wrote.
Before moving east, the storm caused the death of at least one person in South Dakota and two children in Arizona. The storm closed highways in the western U.S., affecting travelers over the Thanksgiving holiday.
Forecasters warn that people traveling throughout the weekend should be aware of the storm's effects.
The storm is expected to hit northeastern states on Sunday, bringing freezing rain and snow.
