With multiple parking structures unavailable indefinitely at Jacksonville International Airport, here's what travelers should know ahead of their flights.

Approximately 600 car owners will be able to collect their vehicles from the hourly garage at the Jacksonville International Airport starting Wednesday after a fire forced the closure of the parking structure on Friday,

"We're not sure if it was a hybrid or not," aviation authority CEO Mark VanLoh said. The state Fire Marshal's Office and agents from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives are on the scene for the investigation.

The closure of a key parking structure at Jacksonville's airport has set off a chain reaction, impacting not just one garage but reshaping the entire parking landscape for air travelers.

The Jacksonville Aviation Authority is expected to get an update at its meeting Monday morning after a devastating fire broke out Friday in the hourly parking garage at Jacksonville International Airport.

Videos posted to social media show black smoke billowing from the structure as emergency responders worked to contain the blaze.
