"Given the challenging situation for running operations in an environment where there was no demand at times due to restrictions and other limitations, we are satisfied with the volumes for the year. Passenger numbers on the Turku route are especially gratifying, with Åland - an attractive holiday destination - seeing a significant upturn in Finland. The summer's special cruises with Viking Cinderella were greatly appreciated by our guests," Jan Hanses, President and CEO, Viking Line, commented.
He furthered, "In the autumn of 2021, the situation started to normalize, but this trend was interrupted by the new Covid-19 variant and subsequent tightening of travel restrictions. We are also pleased that there was great demand for space on our car decks, which is reflected in cargo and car volumes."
