MSC Cruises has postponed the restart of MSC Magnifica by four weeks until 26 September.
The line said it was seeing cancellations and a softening in demand following the recent introduction of additional testing measures for residents of Italy having travelled to Greece. The ship’s itinerary includes as many as three ports in that country.
MSC believes that reservations will start to pick up again in the coming weeks "due to the appeal of the itinerary".
Sales are only open to residents of the Schengen area, with the majority of guests at this stage expected to be Italian nationals and residents.
