Norwegian Cruise Line Holdings plans to expand its Oceania Cruises fleet by two ships to meet heightened demand for upscale cruising.

The New York-listed company today announced an order for two 67,000-gt Allura-Class vessels from Fincantieri as part of its OceaniaNext initiative.

The ships, set for delivery in 2022 and 2025, will be built at a cost of €575m ($730m) each.
