It also features new itineraries in the Mediterranean, Norway, Iceland and the UK in Europe, and North America.
These include a new 30-night itinerary on Arcadia in September 2020, which includes an overnight stop in Boston and three days in New York.
Iona will sail the Norwegian fjords between May and September 2020.
