(1:24 p.m. EDT) -- Editor's Note: As of April 9, all cruise ships over 250 passengers and crew that operate in U.S. waters have been put under a no-sail order by the U.S. Centers for Disease Control and Prevention (CDC). The order will remain in place until COVID-19 is no longer a public health emergency, and supersedes individual cruise line dates for a return to service. For more information, visit our news story.

Cunard has further extended its fleet operations until November 2 for Queen Mary 2 and Queen Victoria and until November 23 for Queen Elizabeth.

It had already and cancelled its entire Alaska season on Queen Elizabeth.

Cunard's President, Simon Palethorpe, said: "With many differing restrictions across countries, people’s ability to move freely and safely across borders remains seemingly someway in the distance.

"For Cunard, where we celebrate having a truly international mix of guests and sail all over the world, this becomes particularly impactful. We also need to better understand the implications Covid-19 will have on board our ships. We are therefore working, at the highest level possible, with government bodies, including the US Centers for Disease Control and Prevention (CDC) and Public Health England, as well as the industry collective body -- CLIA -- and other expert medical professionals to review every aspect of a holiday with us."

He added: "Whilst we have always taken pride in having the highest levels of health and safety we are looking at enhanced protocols across all aspects of ship life and experiences on shore. We will only return to service when we have a comprehensive restart protocol with the stamps of approval and accreditation from the most trusted and informed sources."

As Cunard has done previously during this pause period, guests who are booked on cancelled voyages will automatically be given a 125% Future Cruise Credit. This can be redeemed against any new booking made by the end of December 2021 on any voyage that’s on sale at the time of booking.

Passengers may now also use their FCC for a second cabin to bring friends or family or to upgrade an existing booking.
