The agreement supersedes a pledge by Clia lines to voluntarily suspend operations up to 15 September, and extends a month beyond the US Centers for Disease Control and Prevention’s current no-sail order, which runs until 30 September.

"We believe it is prudent at this time to voluntarily extend the suspension of US ocean-going cruise operations to 31 October," said Clia in a statement.

"This is a difficult decision as we recognise the crushing impact this pandemic has had on our community and every other industry.

"However, we believe this proactive action further demonstrates the cruise industry’s commitment to public health and willingness to voluntarily suspend operations in the interest of public health and safety, as has occurred twice prior."

Clia added its cruise line members would continue to monitor the situation.

"We will revisit a possible further extension on or before 30 September," said the association.

"At the same time, should conditions in the US change and it becomes possible to consider short, modified sailings, we would consider an earlier restart."
