Saga has suspended its cruise programme until spring 2021 due to the tightening of coronavirus restrictions.
Spirit of Discovery will restart sailing in April, while the inaugural cruise of the line’s next new-build vessel, Spirit of Adventure, will take place in May.
A spokesperson said: "With Covid-19 bringing increasing restrictions to day-to-day life and most countries still not accepting cruise ships, we have taken the decision to further extend the suspension of our cruise operations."
Saga said cruise bookings for 2021 and 2022 "remain strong" showing evidence of "pent up demand for our boutique cruise offer".
"The health and wellbeing of our guests and crew, however, is our number one priority and we have taken our decision to extend the cruise suspension against that backdrop," the spokesperson added.
