The impact of Hurricane Ian on Florida’s airports has been extreme. The majority of airports closed down due to the intensity of the hurricane. Since last week Monday, more than 21,000 flights were canceled and the majority of airports left out of operation.

It seems things are slowly starting to return as Florida’s airports begin to open. Tampa International Airport (TPA) suspended flights at 5 pm on Tuesday and restarted its operations on Thursday 29 September. Several other major airports are reopening to the public.

Many airports across the center of the county reopened with humanitarian flights only. As many continue their clean up operations, the entire state is looking at a slow recovery form the category 4 hurricane.

Slow progress:

The majority of the main U.S. airlines serving Florida, including the country’s four largest carriers American Airlines, Delta Air Lines, Southwest Airlines, and United Airlines had previously issued travel advisories.

Currently, Southwest Florida International (KRSW) and general aviation-only Page Field (KFMY)—have power and are receiving military and humanitarian flights only, according to AIN.

Some airports are making slow plans to open safely and fully. Southwest Florida International Airport (RSW) will reopen to the public under a limited schedule on Wednesday, officials confirmed. It will tentatively open on October 7 to the public.
