Hundreds, if not thousands, of travelers could be stranded in South Florida Monday and Tuesday as Sandy batters the Eastern Seaboard.
At Fort Lauderdale-Hollywood International Airport, more than two dozen arrivals and more than three dozen departures were showing as canceled on flight boards early Monday.
Palm Beach International Airport and Miami International Airport also had canceled flights.
"It's going to get significantly worse [Monday] and the next day," said Fort Lauderdale airport spokesman Greg Meyer. "The storm will have a huge impact on the New York region and that's Fort Lauderdale's number one destination."
PBIA spokeswoman Cassandra Davis said she did not have an accurate count on the number of cancellations Sunday. Officials at all three airports are urging travelers to check with their carrier before coming to the airport.
Flights going anywhere from the Washington, D.C.-Baltimore area all the way up to Maine could be affected, said Meyer.
The airports will provide travelers with a list of hotels if they have to stay in the area longer than they expected.
Flights out of Fort Lauderdale-Hollywood called off Monday included trips to all three of the New York-area's major airports as well as airports in Washington, D.C., Philadelphia and Boston.

The storm is also wreaking havoc on air travel.
All Monday flight operations at the Philadelphia International Airport have been canceled, an airport spokeswoman said.
Delta said flights from Washington to Boston will stop Monday morning. The airline had already canceled all flights out of New York and Philadelphia starting Sunday evening.
United Airlines canceled about 3,700 flights between Sunday and Wednesday.
Both companies are allowing some customers to change their flight plans without paying any fees due to Sandy.
Delta will let those ticketed to fly between Sunday and Wednesday -- to and from airports in 15 states and the District of Columbia -- to reschedule by November 4. United's offer applies to travel to and from 29 airports, for the same dates.
Other airlines, such as American, are offering a similar process, with slight variations.
Train service derailed
Amtrak said it is canceling almost all services on the eastern seaboard Monday.
Bus lines connected to those trains were also canceled.
For all the potential headaches at airports, train stations and bus terminals, the type of transportation affected first and most directly by Sandy may be boating.
All along the East Coast, meteorologists and officials have warned people to steer clear of the seas because of potentially perilous high winds and large waves tied to the storm.
Pam and Bob Haigh of Rhode Island had planned to sail from Maryland to the Florida Keys until Sandy
"We've got a surprise, so we'll just ride it out," Pam Haigh said. "There's not much else we can do."
Here's what to expect in New York, Washington, Philadelphia, on the railways and in the sky:
In the city that never sleeps, New York's ubiquitous subway and bus services came to a halt Sunday night.
"The storm is coming ... and now it is time to take action," New York Gov. Andrew Cuomo told reporters. "A situation like this, you don't want to be overly panicked and overly prepared, but you want to be prudent and you want to do what is necessary."
It's rare for New York's massive transit network, the largest in North America with about 8.5 million riders a day, to shut down.
But Cuomo said the move was necessary because it's not safe to operate trains in high winds. Equipment could also become damaged.
It's unclear how long the system will be down.
"Service will be restored only when it is safe to do so, after careful inspections of all equipment and tracks. Even with minimal damage, this is expected to be a lengthy process," the Metropolitan Transportation Authority said on its website.
Second only to the New York system in terms of size, the Washington Metro system will also stay idle on Monday. About 1.5 million people use the Metro each day.
It's unclear when bus service and rail service will be restored, the Washington Metropolitan Area Transit Authority said.
The 770,000 riders who use public transit each day in the Philadelphia area each day will also have to do without.
The Southeastern Pennsylvania Transportation Authority (SEPTA) urged those who do not need to travel to stay off the
Just like with New York and Washington, it's too early to say when public transit in Philadelphia will be restored.
Meanwhile, NJ Transit has suspended all bus, rail, light rail and Access Link service in New Jersey.
"This is a dangerous and destructive Hurricane with the potential to cause large-scale power losses, wind damage and both coastal and river flooding -- all of which will impact NJ TRANSIT service during and after the storm," Executive Director James Weinstein said in a written statement.
Department of Transportation Commissioner James Simpson said the suspension will also better support the state's response to Hurricane Sandy by freeing up buses or other resources that may be needed for hurricane relief.
