Washington - Airlines and airports in the southeastern United States are preparing for hurricane Florence. As a precaution, about four hundred flights that would be flown on Wednesday and Thursday have been canceled at the airports across North and South Carolina.

Florence is expected to affect the southern part of North Carolina on Friday. Airlines have already put additional safety precautions in effect to ensure that customers, employees, and facilities remain safe.

The airlines offer passengers the possibility to change their tickets free of charge to another date or to change the destination of their trip. The number of canceled flights is still relatively limited because there are few large hub airports in the area.

The largest airport in the region is in Charlotte, an important hub for American Airlines. For the time being, no flights have been canceled at the inland airports, although this may change in the coming days. The hurricane Florence can last for days, officials say.
