Cruise Turkey port calls canceled for Norwegian, Oceania and Regent By Tom Stieghorst / January 22, 2016 Share 1 -- Norwegian Cruise Line Holdings said it will cancel calls in Turkey for the rest of 2016. The move affects 32 itineraries sailed by Norwegian Cruise Line, 17 for Oceania Cruises and 12 for Regent Seven Seas Cruises. The lines go to five ports of call in Turkey, including Istanbul, where a suicide bomber killed 10 people, mostly tourists, on Jan. 12.Guests will instead go to Greek ports of call, primarily Athens and Santorini, Norwegian CEO Frank Del Rio said.“This is one of the toughest decisions I’ve ever had to make, itinerary-wise, because Turkey is very near and dear to our hearts,” Del Rio said.The decision was based on intelligence about possible terrorism over the past several months, as well as the Jan. 12 bombing, Del Rio said. For the safety and security of guests, “The correct course of action is not to call on Turkish ports in 2016.”Other cruise lines have canceled calls in Turkey but on a much more limited scale. Crystal, for example, has scratched Turkish calls on two cruises this spring in favor of Greece. MSC Cruises said its MSC Magnifica ship won’t call in Turkey until further notice.Del Rio pointed out that last year when some other cruise lines canceled calls to Turkey in the third and fourth quarters, NCLH didn't. "We held out. We had confidence things would turn around,” he said.He said that when calm, Greece and Turkey are among the best destinations to visit and some of the highest yielding ones for cruise lines. “If you want to get a taste of what Eastern life is like, Istanbul is the place to go,” said Del Rio, who also praised Kusadasi as one of the top three places to see Roman ruins in the world.Guests not past final payment can either cancel the cruises or move them to other itineraries, Del Rio said. “If in a month everything is calm and collected, then I made the wrong decision,” he added.
