Hundreds of flights have been canceled due to Hurricane Dorian’s looming threat to the U.S. east coast, USA Today reports.

There are also reports of mass cancelations at the Orlando Sanford International Airport and the Fort Lauderdale International Airport, according to FlightAware, the USA Today reported:
