Another storm disrupts air travel in Northeast

For the third time in a month, airline passengers are navigating a sea of canceled and delayed flights as a winter storm disrupts travel in the Northeast.

The storm dumped more snow than forecasters had predicted, closing runways and clogging roads leading to airports today.

About 1,500 passengers were stranded overnight at Philadelphia International Airport, according to an airport spokeswoman. A foot and a half of snow in New York virtually shut down LaGuardia and Kennedy airports.

Airline officials, however, expect the storm to cause fewer hassles than major winter blasts in late December and mid-January because of lighter traffic.
