Helene, which strengthened to a Category 1 hurricane on Wednesday morning, has prompted airlines with routes in the region to take preventative measures and alert travelers of potential impacts to itineraries.
"Helene is expected to rapidly intensify and grow in size over the eastern Gulf of Mexico," the National Hurricane Center said in an announcement Wednesday. "There is danger of life-threatening storm surge along the entire west coast of the Florida Peninsula and Florida Big Bend."
While all airlines are required to offer a full refund to customers if a flight is canceled or significantly delayed due to reasons within the airline’s control, per the Department of Transportation, that rule does not encompass weather-related delays or cancellations.
American Airlines
American issued a travel alert for the Gulf of Mexico that affects 23 airports, with 16 of those in Florida, including Tampa and Sarasota.
For passengers who bought tickets of any fare class before September 23 for travel between Sept. 24-27, the change fee will be waived.
Changes must be booked by September 27, and travel must be for the same travel origin and destination.

The Atlanta-based carrier shared a weather advisory for Tropical Storm Helene due to forecasted path, explaining that "travel may be impacted to/from/through" 17 destinations.
