Uber switched over a PIN system overnight to match the demand on the busy travel day and airport officials told passengers there were alternatives to get home. 

LAX was also slammed with delays due to a snowstorm. The airport warned that "heavy flight volumes continue as a result of weather delays on the East Coast." reported that more than 200 flights into or out of the U.S. are canceled as of Monday morning. Many canceled flights were at New York and Boston-area airports.

The storm dumped one round of snow on parts of the region late Sunday and could drop 10 to 20 inches total by Tuesday morning from Pennsylvania to Maine, forecasters said. Heavy snow was also possible in the Appalachian Mountains down to Tennessee and North Carolina.
