Brazilian airline TAM confirmed that seven flights from Rio and Sao Paulo to New York City were canceled for Sunday and Monday. Three more flights are to be canceled for Tuesday.

Copa Airlines has suspended flights to New York and Washington D.C. until Tuesday. Colombian airline Avianca has done the same.

United and Delta warned that flights to several cities in the American east coast could be canceled due to the storm.
