The cruise line had previously suspended all voyages until 1 July but said the decision to extend cancellations for a further eight weeks was made because of the “continued escalation” of the coronavirus around the world.

CMV said it would continue to offer a 125% future cruise credit voucher on the original cruise price to affected passengers – the vouchers are valid for redemption until 31 March 2021.

Chief executive Christian Verhounig said: “We are still unable to perform our scheduled itineraries and to deliver the travel experience normally enjoyed by our valued passengers.

“We are extremely proud to see that 70% of our passengers affected by the cancellation of their cruise have either rebooked and transferred onto a future 2021 cruises or require more time with the peace of mind of a refund credit note.”

CMV is also offering increased flexibility to passengers booked on cruises scheduled to leave after 25 August, including the ability to cancel up to seven days before departure and receive a 125% future cruise credit.
