Viking Cruises is celebrating its 20th anniversary this year, marking two decades of innovation in the cruising category.Founded in 1997 by Chairman Torstein Hagen with the purchase of four river ships in Russia, Viking now employs over 4000 staff worldwide. In 2000, Viking purchased Europe’s KD River Cruises to grow its fleet, to leverage 175 years of river cruising experience and to acquire rights to prime docking locations in key European cities.Viking is continuing its significant rate of expansion in its 20th year of operation. The company has already welcomed two new Viking Longships in Europe and its third ocean ship, Viking Sky was christened in February. Its fourth ocean ship, Viking Sun, will debut in October and will visit Cuba before embarking on a 141-day World Cruise. Viking Spirit will join the fleet in 2018, and will sail itineraries in Australia, New Zealand, Asia and Alaska. A sixth, yet-to-be-named sister ship will be delivered in 2019.“2017 is an exciting year for Viking, as we continue to welcome new ships to our fleet and offer new itineraries across the world,” said Michelle Black, managing director, Australia and New Zealand. “We also have seen a great response from the Australian and New Zealand market for our ocean offering. Our destination-focused approach with compelling itineraries, combined with our extensive on-board inclusions and beautiful ships are proving to be a winning formula with this market.”To celebrate its 20th anniversary, Viking is offering the opportunity to fly free to Russia where it all began and save either $3000 per couple or fly free to Russia and save $2000 per couple, when booking a 2018 Russian river cruise. Offer is only valid until 30 June 2017.
