Several cruise lines are adding capacity to the market in September according to the latest edition of the Cruise Ships in Service Report by Cruise Industry News.

While major brands such as Holland America Line and Princess Cruises are reactivating additional vessels, other companies are also adding new tonnage to the market.

Viking will be welcoming two ships during the month, the Viking Mississippi and the Viking Polaris. While the first marks the company debut in the Mississippi River which happened in early September, the second completes the brand’s expedition fleet on September 29.

Norwegian Cruise Line is also adding a newbuild to its fleet this month. After celebrating the vessel’s christening in August, the company saw the Norwegian Prima departing on its first revenue cruise on September 3. 

Meanwhile, other cruise lines, such as Australis, are resuming service after their regular in-between-season operational pauses.
