Because of the COVID-19 pandemic, in February 2020, Celebrity cancelled all Asia cruises on "Celebrity Millennium" and re-deployed her to Los Angeles to sail complimentary cruises in March and April 2020 for first responders and military personnel. However, all sailings were cancelled after the company halted operations on 13 March 2020. The ship has been berthed or anchored offshore near San Diego throughout the pandemic; after months of difficulty repatriating crew members, up to 480 crew members still remained on board the ship in May 2020.
