Airlines are offering the passengers the chance to rebook their travel plans without the usual fees as Hurricane Irma strikes the Caribbean and threatens to hit Florida next.

Key West International Airport announced Tuesday that it's suspending operations late Wednesday "until further notice." Other Florida airports have thus far cancelled a smattering of Caribbean-bound flights. Irma's effects on travel will only worsen as the storm draws closer to Florida.

Here's what each airline is offering passengers forced to change their plans because of the storm, a Category 5 hurricane and among the strongest such storms ever recorded in the Atlantic. This information is up to date as of Wednesday afternoon, but travelers should check in with their individual airlines for more information.

American Airlines is offering travel waivers for flights between Sept. 5-12. Anyone traveling to or from Florida through Daytona Beach, Fort Lauderdale, Fort Myers, Key West, Melbourne, Miami, Orlando, Palm Beach, Tampa or Sarasota is eligible for a waiver. Travelers flying to or from airports throughout the Caribbean are also eligible for a change fee waiver.

Delta is waiving fees and extra costs associated with flights to and from Florida, the Bahamas and Cuba scheduled for Sept. 6-17 as long as passengers fly on or before Sept. 30.
