U.S. airlines have canceled about 2,900 flights because of snow and freezing rain in the Northeast and the Midwest.
Wednesday was the third consecutive day bad weather snarled air traffic. The flight tracking website FlightAware says Wednesday's disruptions followed 1,600 cancellations Tuesday and 2,100 Monday.
Fliers should get a break Thursday with few flights expected to be affected by weather.
Most of Wednesday's canceled flights were from the New York-area airports, Boston, Chicago, Philadelphia and Washington. Regional airline Cape Air canceled more than 200 flights, including nearly every flight planned from airports in Massachusetts.
United Airlines says the disruptions also affected flights in the Midwest, including Chicago and Cleveland. United and other airlines are allowing passengers to change their tickets without the usual change fees.
