(3:15 p.m. BST) -- Fred. Olsen Cruise Lines is giving passengers a free all-inclusive upgrade on more than 75 ex-U.K. sailings in the 2020/21 cruise season. The perk includes house wines by the glass, as well as selected beers, spirits and soft drinks.

The upgrade will be available on sailings to the Baltic and Norwegian fjords plus warm weather European destinations.

Jackie Martin, sales and marketing director at Fred. Olsen Cruise Lines, said: "This incentive is perfect for those who prefer not to fly.
