The line had previously announced the halting of cruises on all ships except Norwegian Encore, Norwegian Escape, and Norwegian Joy but has now extended that to include its entire fleet.

NCL said it would continue to “closely review” the US Centers for Disease Control and Prevention’s conditional sailing framework issued on 30 October and “continue to partner with global and domestic authorities, including the CDC, to chart a path forward”.

“We are committed to taking all appropriate steps and actions to combat the spread of Covid-19 and are working closely and in partnership with local, state, federal and global agencies,” the line said in a statement on its website.

“Whilst this may result in additional future changes, please know our teams are working around the clock to do what is right by our guests and travel partners. We continue to monitor this situation closely and will provide additional updates as they are available.”
