Norwegian Cruise Line Holdings has announced an extension of its previously announced suspension of global cruise voyages through May 31, 2021 for the Norwegian Cruise Line, Oceania Cruises and Regent Seven Seas Cruises brands.

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

Norwegian said it 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 who are currently booked on cancelled voyages on Norwegian Cruise Line, Oceania Cruises or Regent Seven Seas Cruises are asked to contact their travel advisor or the cruise line for more information.
