Outrage has spread amongst survivors of the Costa Concordia disaster as the ship’s owners offered them 30% off their next cruise.



Carnival Corporation, which runs Costa Cruises, made the offer to passengers of the Costa Concordia who endured a horrific ordeal when the ship ran aground on 13 January.



The number of confirmed deaths in the wreck rose to 13 on Sunday, with 20 more missing. Divers are continuing to search the shipwreck in order to search for others who may have died in the tragedy.

Passengers have been offered a full refund on the original voyage, as well as this recent discount off their next trip with the cruise company. The offer has been met with derision by Concordia survivors with one passenger telling ‘The Telegraph’ that it was “insulting”.



“The company is trying to do everything they can for those passengers directly affected,” a Costa Cruises spokesperson said.



“The company is not only going to refund everybody but they will offer a 30% discount on future cruises if they want to stay loyal to the company.”



Some 4,200 passengers were forced to flee the Costa Concordia as it ran aground off the coast of Isola del Giglio on 13 January. The ship’s captain Francesco Schettino has claimed that his “sail-by” of the island was arranged by Costa Cruises “for publicity reasons”.
