Tropical Storm Isaac is forcing some airlines and cruiselines to make changes to flight and ship schedules to avoid its path.
At Fort Lauderdale-Hollywood International Airport six flights were canceled and one delayed early Friday due to the storm, the airport's community outreach coordinator Allan Siegel said.
The affected destinations are Santo Domingo, Dominican Republic and Port Au Prince, Haiti.
There no were flight cancellation or delays showing for Palm Beach International Airport, according to the flight tracking information on its website.
At Miami International Airport only four arrivals and two departures have been canceled so far by American Airlines to and from Haiti and the Dominican Republic through 7 p.m. , airport spokesman Greg Chin said.
On Thursday, there were 11 cancellations at MIA, all by American Airlines, including six departures and five arrivals to and from St. Thomas, Antigua, St. Kitts, St. Croix, St. Maarten, Punta Cana and Santa Domingo, Chin said.
If planning to travel today or this weekend travelers are advised to check with their airline for storm-related updates and policies regarding change fee waivers and options for rebooking, before heading out to the airport.
Miami-based cruise operators have also been revising schedules of some ships sailing in or headed to the Caribbean.
Royal Caribbean International said Friday its ships Majesty of the Seas and Monarch of the Seas will not call on CocoCay, its private island in the Bahamas, this weekend.
The cruise line is also advising passengers sailing on Allure of the Seas Sunday from Port Everglades and on Majesty and Monarch departures for Monday, to monitor its website royalcaribbean.com for updates.
Carnival Cruise Lines has revised schedules for Carnival Liberty and Carnival Valor, which departed PortMiami Aug. 18 and has amended Carnival Ecstasy's itinerary, which sailed from Port Canaveral on Thursday.
Norwegian Cruise Line has modified itineraries for Norwegian Sky, which is expected to sail on schedule Friday from Miami to the Bahamas, but will bypass Great Stirrup Cay on Saturday for a stop in Nassau instead.
Changes have also been made to Norwegian Gem and Norwegian Dawn itineraries, the cruise line said Friday, in a statement.
With the hurricane season now at its peak, travel specialists are advising travelers to consider buying travel insurance if flying or cruising during high season.
While airlines will typically offer to change flights without a fee when bad weather strikes, and cruise lines will make efforts to stop at alternative nearby ports, travelers arent likely to get a full refund of all travel costs in the event a trip is cancelled due to a storm, experts say.
In a recent AAA survey of 609 residents in the Southeastern U.S., 44 percent of travelers polled believed airlines, hotels, and cruise operators will reimburse all travel costs for cancellations due to weather catastrophes and natural disasters.
But AAA says that isn't typically the case.
"For many travelers, it seems it would make sense for a travel provider to refund the full costs of cancellations that result from something out of the traveler's control, like severe weather. Unfortunately, many travelers learn the hard way that this is not always the case," said Brent Hubele, vice president, AAA Travel, The Auto Club Group, in a statement. "Weather is always unpredictable and a prime example of the importance supplemental travel insurance."
