Airlines scrambling ahead of Hurricane Dorian Airlines are already sending out alerts to passengers traveling through Florida, which is home to four of the nation's biggest airports. On Friday, the big carriers started offering waivers, allowing passengers to change their flights through Florida airports without penalty. Miami is a hub for American Airlines, which is offering waivers to 13 of the 16 airports they service throughout Florida. But with Dorian still a few days away, some fliers are making their getaway now. Mark Strassman reports.
