ATLANTA — Amidst a wave of mysterious illnesses affecting American tourists in the Dominican Republic, Delta is allowing passengers who have trips booked there a chance to change their plans free of charge.

Delta’s offer is open to people who have booked flights to Punta Cana in the Dominican Republic this summer, from June 21-Aug. 15. 

Passengers will be allowed either to change their destination or cancel their flight and be able to put the value of the ticket toward a future trip.

Those who wish to rebook can do so by Nov. 20, and Delta will waive change fees. 

If you cancel, you'll have a year to put the value of your ticket toward another flight, though change fees will still apply.

Steps for rearranging travel can be found at Delta’s website.

Last week a New Jersey man became the ninth American tourist to die in the Dominican Republic in the last year.

The string of deaths have all occurred under murky circumstances, though officials have not positively linked any of them.

According to NBC News, the FBI is already investigating some of the deaths.
