Hurricane Sandy is shutting down air operations throughout the mid-Atlantic and Northeast, with the flight-tracking website Flight Aware reporting 8,900 flights canceled since Sunday.
Philadelphia had more than 1,000 flight cancellations on Monday. No flights are expected to operate from Philadelphia until the middle of Tuesday at the earliest.
No flights were operating out of New York-area airports on Monday, according to the Port Authority of New York and New Jersey.
The hurricane is having a ripple effect at airports across the U.S. More than 350 flights out of Chicago O'Hare had been canceled, mostly due to Sandy. About 75 flights from the Twin Cities to the East Coast were canceled due to the storm, according to a spokesman for the Minneapolis-St. Paul International Airport.
American Airlines said that it is canceling flights out of several airports in the mid-Atlantic and Northeast through the middle of Wednesday and that there could be additional delays and cancellations after that.
Airlines were waiving penalties for passengers whose flights are impacted by the storm and offering refunds for canceled flights or flights that were “significantly delayed.”
Delta's website tells passengers that if their flights are canceled or “significantly” delayed, they get a refund. United Airlines said passengers get refunds if flights are delayed by more than two hours or if flights are canceled.
Airlines are waiving change penalties for travelers to much of the mid-Atlantic and Northeast between Oct. 28 and Oct. 31. Most airlines were requiring travelers to rebook their flights by Nov. 4 and some are requiring travelers to begin their rebooked travel by Nov. 4. United is giving travelers who opted to change their travels up to a year to use the tickets.
