TULSA, Oklahoma - This morning Hurricane Dorian has been upgraded to a Category 5 storm and with new models showing Dorian changing paths, travelers are on alert.

Airlines are closely watching Dorian's shifting path before they make any changes. American Airlines, which has a maintenance base in Tulsa, has issued a travel alert for more than 15 airports in the Caribbean and Florida.  

The airline says it will waive fees if a customer doesn't want to fly to or from an airport included in the alert. With this being labor day weekend, millions of travelers could be impacted.
