Holland America Line has extended its operational pause later into the year, and partially into 2021.
Several 2020 Vancouver sailings and early 2021 Hawaii itineraries have been cancelled.
HAL said the decision owed to ongoing travel and port restrictions arising from global health concerns.
Guests booked on affected cruises will be automatically issued future cruise credit (FCC).
They can, however, opt for a full refund, but must notify HAL of their preference by 15 July.
