(CNN) - More than 1,300 flights have been canceled in advance of Hurricane Florence's arrival in the Carolinas, and operations at airports along the coast have been suspended as the region braces for landfall.
On Thursday alone, more than 600 flights were canceled with about 700 already grounded for Friday, according to flight tracking site FlightAware.com.
Outer rainbands of the Category 2 storm with tropical-storm-force winds had started lashing North Carolina's coast by mid-day Thursday.
FlightAware doesn't anticipate closures at any East Coast hubs (Charlotte, Atlanta or any D.C.-area airports), limiting "cascading disruption to the rest of the nation's airport system," spokeswoman Sara Orsi said in a statement.
Airlines have extended waivers and advisories for travelers with itineraries involving airports in the path of the storm.
Carriers including American Airlines, Delta Air Lines, Southwest Airlines, United Airlines, Alaska Airlines, JetBlue Airways and Spirit Airlines have all posted information for travelers online about fee-free changes to affected itineraries this week.
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.
Runways at South Carolina's Charleston International Airport closed late Wednesday night and may not reopen until early Saturday morning, according to an update on the airport's web site. The airport is served by eight airlines.
Myrtle Beach International Airport in South Carolina has also suspended commercial operations and urges passengers to check with their airlines -- not the airport -- about upcoming itineraries.
Services and flights have been suspended on Thursday and Friday at Wilmington International Airport on North Carolina's coast.
Hundreds of miles inland, Charlotte Douglas International Airport already has more than 300 flight cancellations for Thursday and Friday, according to FlightAware. Raleigh-Durham International Airport had a similar number of cancellations for those two days.
Wind and the tidal surge will be the biggest issues for airports in the coastal Carolinas, FlightAware's Orsi said. "Once the storm moves further inland to Atlanta and Charlotte, the biggest issue will be rain and thunderstorms," she said.
Boeing evacuated several new 787-10 Dreamliner jets from its factory in North Charleston, South Carolina, to protect them from the storm. Concern was high enough for the expensive jets that the plane manufacturer flew them all the way across the US to its main facility outside Seattle, Washington.
