Operations at many airports along the coast remain suspended as the storm, downgraded to a tropical storm Friday afternoon, slowly moves through the Carolinas.
Service at Wilmington International Airport was suspended Wednesday and was expected to remain halted through Friday, FlightAware said. Operations at airports in New Bern, Fayetteville and Jacksonville, North Carolina, and Myrtle Beach, South Carolina, were also expected to remain suspended through Friday.
Hundreds of miles inland in North Carolina, Charlotte Douglas and Raleigh-Durham international airports have seen some of the most significant cancellation numbers, with more than 450 across the two airports Friday, according to FlightAware figures.
Airlines have extended waivers and advisories for travelers with itineraries involving airports in the path of the storm.
All four major US airlines have said they are capping selected airfares below what last-minute tickets would cost. Last year, some airlines caught flack because of high fares in advance of Hurricane Irma.
Rail and cruise ship travel have also been affected by the dangerous storm.
Amtrak will waive charges for reservation changes for the affected period and routes. Call the reservations center at 800-USA-RAIL.
