The DFDS Newcastle to Amsterdam ferry service has been suspended until June.
The ferry, which sails from the North Shields port, has had to be temporarily halted due to the coronavirus outbreak.
The company says the suspension will now run up to and including June 3 at the earliest.
In a Facebook message to customers, Kasper Moos, vice president and head of passenger business, said: "Due to continued Government measures intended to prevent the spread of Covid-19 virus, we will unfortunately now suspend sailings on our Amsterdam Newcastle service up to and including 3rd June.
"We fully understand the Government precautions have important health goals, and as our priority is to ensure the safety and health of our customers and crew, we have taken this difficult decision.
