US Airways canceled four arrivals and four departures of flights between Long Island and Philadelphia and Washington.
Jean Goodmok, 73, of Melbourne, Fla., was at MacArthur for Southwest Airlines' first flight to the Sunshine state. She said she was glad that the planes were flying today.
Goodmok said she was fleeing her son's home in Freeport, which was without power, cold and had a basement filled with water.
"I couldn't print my boarding pass or anything because I'm on the South Shore," Goodmok said. "It was so cold. No electric. No gas. You can't get a cup of tea."
Another traveler on the first Florida flight was Megan Kelleher, 24, of Orlando, who said Sandy forced cancellation of two other flights she booked on Sunday and Monday.
