Norwegian Cruise Line, Oceania Cruises and Regent Seven Seas Cruises have extended the suspension of all cruises up to May 31, 2021.

The Norwegian Cruise Line Holdings brands had previously suspended all cruises up to April 30, 2021.

The company said it will continue to work through its return to service plan to meet the requirements of the Framework for Conditional Sailing Order issued by the US Centers for Disease Control and Prevention.

NCLH added: “The company will continue to work in tandem with global government and public health authorities and its Healthy Sail Panel expert advisors to take all necessary measures to protect its guests, crew and the communities visited.”

Guests booked on cancelled voyages on Norwegian Cruise Line, Oceania Cruises or Regent Seven Seas Cruises are asked to contact their travel agent or the cruise line for more information.
