Hurricane Sandy has stranded many Chicago travelers again today.

Most flights heading to the Northeast coast are still canceled as airports deal with the aftermath of the storm system.

The Chicago Department of Aviation said about 325 flights out of O’Hare and 75 at Midway were canceled Tuesday.

The massive storm system has also kicked up winds in Chicago that are causing travel delays.

“We have high winds and it’s going to necessitate either delays or additional cancellations on the part of air carriers that operate (in Chicago),”  said American Airlines spokesperson Mary Frances-Fagan. “In times like this, bring your patience with you to the airport.”

On Monday, more than 450 flights at O’Hare International Airport and more than 100 at Midway International Airport were canceled.

Officials said it could be days before some passengers can get to their destinations.

Worldwide, more than 15,000 flights have been cancelled because of the storm system.

Chicago officials said travelers should check with airlines before leaving home for the latest flight information.
