Cruise lines are monitoring the development of political situation in Turkey and at least two lines have decided to restrict their calls in the country.

Costa Crociere, which is part of Carnival Corp & plc group, has suspended calls at Turkish ports for the rest of the current year. The four ships concerned will call at ports in Greece, Italy and Malta instead.

Celebrity Cruises, the premium market unit in Royal Caribbean Cruises Ltd (RCCL) group, has decided to abandon an overnight call at Istanbul, the largest city in Turkey and a major cruise destination, on the first weekend of September by one of its ships.
