On November 20, Princess and Holland America Line both announced they would cancel all cruises until the end of March 2021 in order "to allow time for the estimated preparation needed for completing required activities prior to sailing". Select longer Holland America sailings in Australia, New Zealand, Asia and South America are additionally suspended through mid-April 2021.
Both lines also noted they would follow sister brand Carnival in not selling any cruises more than seven days in length, in keeping to the Centers for Disease Control (CDC) new guidance. Princess has also paused its operations in Japan until June 25.

On November 19, Viking announced it would suspend all river and ocean sailings through January 31, 2021. Viking notes that it has " also cancelled additional sailings further into 2021 because of regional complexities", without specifying what those sailings were.

Meanwhile, in Australia, operators including Azamara and Celebrity have canceled their entire 2020-2021 seasons, while other lines, including Carnival, have significantly postponed their return to service Down Under.
