Seabourn is the latest cruise company to extend the suspension of sailings.
The luxury line’s five ships will not operate up until June 30.
The latest wave of cancellations follow a pause in cruises between March 14 and May 14.
“The decision is a proactive response to the unpredictable circumstances evolving from the global response to the Covid-19 situation,” the Carnival Corporation-owned company said.
“Seabourn will be communicating changes for voyages scheduled to depart in the extension window with all booked guests and their travel advisors.”
Passenger booked on affected cruises will receive a 125% refund in the form of a future cruise credit, which must be booked by December 30 but can be used towards any cruise up to the end of 2021.
Otherwise, full refunds are being offered.
“Guests and their travel advisors will be sent details on how to manage cancellations and desired compensation online,” the company added.
“Seabourn asks guests and travel advisors to use the online resources available first rather than calling the reservation call centre for information about the cancellations due to the possibility of high call volumes and the potential of long on-hold wait times.”
