According to CNN, the flights covered are to and from Punta Cana in the Dominican Republic.
Just last week, an eleventh American died in the Caribbean nation.
Passengers can cancel or change their flights without being punished. Passengers must have booked a trip prior to June 21 in order rebook or cancel their trip, according to Fox News.
Although the U.S. State Department issued a travel advisory in April urging American tourists to "exercise increased caution in the Dominican Republic due to crime," officials have not revised the notice to include any health warnings. In fact, the department said last week that it has "not seen an uptick in the number of U.S. citizen deaths" in the popular vacation destination, ABC News reported.
