Crews were busy de-icing planes to try and help with the bad situation as the National Weather Service called a WINTER WEATHER ADVISORY on the area.
The word "canceled" could be seen on flight boards throughout the busy airport.
Some passengers took advantage of the delay to catch up on some sleep while others simply hung out and chatted with one another.
Airport officials say the airport remains open even as American Airlines says they have had to cancel about 340 flights out of there on Tuesday.
