PHILADELPHIA (CBS) – Normally, bad weather means planes are grounded. But on Monday, the planes at Philadelphia International Airport were gone.

Due to Hurricane Sandy, all Monday flights have been canceled, with the last departure around 11:30 p.m. on Sunday. Not only that, but the airlines have moved all of the planes out of PHL – some flying as far away as Denver, Colorado.

For example, US Airways has canceled a total of 1641 flights system wide — more than half of the company’s total daily flights. Trans-Atlantic flights destined for PHL are remaining in Europe until Wednesday. In addition to canceling flights Monday in Philadelphia, all New York area airports and Washington DC, the decision had been made to cancel ALL US Airways operations for Tuesday, October 30 at PHL, DCA, BOS and all NYC area airports (and satellite cities in the Northeast).

The airport says it will continue to assess the situation throughout the day, but travelers are urged to stay home and check their flight status by calling the airline or calling PHL’s toll free flight information number 1-800-PHL-GATE (1-800-745-4283) or visit for updated information. SEPTA transit service, including the Airport Rail Line, has also been suspended until further notice.

The last time the planes left the airport was Hurricane Irene in 2011.
