Disney Cruise Line has extended its sailing suspension once again. 

On Tuesday, the operator announced that it has canceled all cruises departing from the U.S. through June 2021.

Disney’s decision to cancel more of its cruises comes days after the U.S. Centers for Disease Control and Prevention (CDC) released further information on how cruise lines can begin the process of returning to sea with enhanced coronavirus health and safety measures.

In its announcement on Tuesday, Disney said it is reviewing the CDC’s guidance and "working toward resuming operations."

Disney is also working on a plan to bring Disney Wonder back to operations in Alaska in light of Canada’s decision to ban ships with more than 100 passengers to dock in the country’s ports until February 2022.

Disney previously extended its cruise suspension in February, saying its U.S. cruises were canceled through May and its European cruises were canceled through August.
