The Government decision was taken over “the unknowns around the Delta variant” among other Coronavirus (COVID) risk factors.
According to a Scottish government spokesperson, the ban would be lifted once the country had reached the lowest COVID restriction level.
Last week, MSC Cruises' liner MSC Virtuosa was prevented from docking in Greenock-Glasgow less than 2 days before her scheduled port call. Several major cruise lines, including Saga, announced they would review the situation ahead of their itineraries which included calls in the country.
Saga (which targets over-50s travellers) has already amended its "Scottish Highlands and Islands" cruise on Spirit of Discovery, departing on June 27, 2021. The revised itinerary will now visit Portsmouth, Portland, Scilly Isles, Falmouth.
Saga’s "From the Northern Isles to the Fjords" voyage (July 3) has also been changed in order to include calls to England's west coast - Portsmouth, Falmouth, Bristol, Scilly, Portland.
On its website, Saga said it would refund 10% of the cruise fare paid “to acknowledge the disappointment this late change may cause”. The cruise line will automatically transfer clients’ bookings to the new itineraries.
