Dozens of flights to the Northeast and Midwest were delayed or cancelled from Tampa International Airport Monday with the onset of a late-winter storm is expected to affect thousands of flights across the country early this week.

Flights to John F. Kennedy International Airport in New York City, Chicago's O'Hare International Airport, Bradley International Airport in Connecticut, and others were affected in Tampa Bay, according to a spokeswoman. There were 76 delayed flights and 25 cancellations in Tampa Bay as of Monday afternoon.

Tracking service FlightAware.com said late Monday morning that more than 1,100 flights on Monday and more than 2,800 on Tuesday had been canceled.

Chicago is bearing the largest share of Monday's cancellations, while Tuesday's disruptions are hitting hardest from Washington to Boston including the New York City area.

The major airlines are waiving ticket-change fees that range up to $200 for customers who want to change their travel plans. Restrictions vary by airline.
