It appears that a relaxing luxury cruise to Turkey is a good way of preparing for the hardships of fighting in the wasteland of Kobane.
The international police organisation, Interpol, is calling for airline security checks to be extended to cruise lines as some of those hoping to fight in Syria and Iraq are now going by sea.
Interpol's counter terrorism chief, Pierre St Hilaire, said there was evidence that jihadis were taking cruise ships to the Turkish port of Izmir.
Carnival’s Costa Crociere subsidiary, MSC Cruises and Norwegian Cruise Line are among the operators offering voyages that include calls at Izmir.
St Hilaire had no details about how may world be jihadis were taking a cruise to war but up to 15,000 foreign fighters are reported to have joined Islamic State and other groups fighting in Syria and Iraq.
"Because they know the airports are monitored more closely now, there's a use of cruise ships to travel to those areas," added St Hilaire.
Interpol wants to extend its I-Checkit programme that allows airlines to check passenger information to cruise lines and others that might be able to detect extremists going off to fight.
But the trade body, Cruise Lines International Association, claims that shipping companies are already taking security as seriously as the airline industry.
