Luxury cruise line Cunard has announced that it is extending its pause of operations until May 2021.
The company said it made the move "due to the ongoing travel constraints in place across the world".
The company has cancelled all voyages on Queen Mary 2 until May 28, and all voyages on Queen Elizabeth until June 4.
Sailings on Queen Victoria were already set to resume from May 17 so this remains unchanged.
The cruise line has said that all passengers affected by the cancellations will automatically receive a 125% Future Cruise Credit which can be used on any booking made by the end of December 2021, on any voyage available at the time of booking.
Passengers who would prefer a refund will need to fill out a form on Cunard.com.
Cunard president, Simon Palethorpe said: "Our extension to the pause in operations is the result of the ongoing restrictions on cruising in the UK and around the world and recognises the significant lead times to return to service, once those restrictions are lifted.
"We are extremely sorry for the disappointment we know this will cause. We know how much careful consideration goes into planning a holiday and apologise that our guests now have to wait a little longer to travel once again with Cunard.
"Guests are able to use their enhanced 125% Future Cruise Credit to book for later in 2021 or for one of our newly announced 2022 voyages.
"The tremendous response already to our 2022 voyages, put on sale just a few weeks ago, clearly demonstrates our guests are eagerly anticipating travelling again with us. We’re equally looking forward to the time when we can welcome back our guests."
