Crystal Cruises has cancelled calls to Turkey on two cruises this spring due to security concerns in Istanbul.
Greek destinations will replace visits by Crystal Symphony to Istanbul and Kusadasi on April 24 and May 1 sailings.
Turkish ports of call scheduled for April and November by Crystal’s new yacht Crystal Esprit will also be changed, although itineraries have yet to be finalised.
The luxury line’s president and chief executive, Edie Rodriguez, said: “The safety and peace of mind of our guests are our primary concerns and we do not take any risks with either.
“The itinerary changes will allow our guests to continue with their planned holidays in the same standard of excellence and luxury, without the added worry of security in a particular destination.”
