Hurricane Sandy is wreaking havoc on the East Coast and that's affecting passengers at Sky Harbor.
The massive storm is threatening to bring a near halt to air travel for two days in the east coast, a key region for both domestic and international flights.
More than 12,000 flights have been canceled worldwide, and thousands of flights have been delayed.
A spokesperson for Sky Harbor Airport said there were flight cancellations Monday to and from Boston, Baltimore, New York City, Washington D.C., and Newark, N.J.
Sky Harbor's two major carriers -- US Airways and Southwest -- canceled at least 30 departures between them Monday. Combined, the airlines offer more than 400 daily flights from Phoenix.
Alan and Ellen Wechsler live in Roseland, New Jersey and were trying to get back to Newark.
"We were in Arizona at a cousin of mine's 80th birthday party, planning on coming back today and found out we were unable to," said Alan Wechsler.
"I went on our tablet, checked our flights and it said 'canceled,'" said Ellen Wechsler.
"We were keeping our fingers crossed we could get into Philadelphia on Monday, but obviously that didn't work," says Nancy Santangelo, stuck at Sky Harbor. She and her husband are on layover from Alaska and will soon go to Dallas as they wait out Hurricane Sandy.
"We were going to fly into Pittsburgh and drive home, but the roads would've been washed out anyway, so we just figured we'd just continue on my business travels and take it from there," says Renwick Santangelo.
All the major airlines grounded all flights into and out of New York's 3 major airports. They also canceled flights to several other east coast cities.
Terry Frenzon is trying to get home to central New Jersey. She tried to switch a flight by phone, but the line was busy, so she went to the airport twice.
"Got in line, waited and hour and a half, and they rebooked me for Tuesday morning, and then I just got a phone call this morning that it was canceled for Tuesday morning. I thought I was just not going to mess with it [the phone] so I came back to the airport," said Frenzon.
The Krausses from Germany are also stuck in Phoenix. Their 2-week stay has been extended after their flight to Newark was canceled.
Tempe-based US Airways says it has canceled all Tuesday flights to and from 22 East Coast airports for a second day. The airports include Philadelphia, Boston, New York and Washington, D.C.
Anyone flying out is advised to check the status of your flight ahead of time.
