P&O Cruises has announced that it has now cancelled all its planned sailings until 2021.
This includes all Caribbean cruises, which have now been cancelled until the end of January 2021.
All cruises from and to Southampton are cancelled through February 2021.
The cruise line, which had hoped to resume operations at the end of November, blamed coronavirus restrictions for the further delays in the resumption of sailings.
P&O Cruises President Paul Ludlow said: “With evolving restrictions on travel from the UK, unfortunately it is necessary to cancel these itineraries.
“These further cancellations vary according to ship as well as complexity and length of itineraries, advice and guidance regarding ports of call and current air availability for fly/cruises.
“We are continuing to monitor the overall situation closely and will certainly reintroduce cruises should the opportunity arise and it is feasible to do so.
“Whilst adherence to the protocols on board and ongoing vigilance will be critical, this will always be coupled with providing the well-deserved and memorable holidays for which we are known, with all the standout moments on board and experiences on shore. This is what we have always done and will continue to do.
“We cannot wait for restrictions to ease, borders to open and for us to once again be able to set sail for a new beginning.”
