This new ship was originally scheduled to be built for P&O Australia, which is another Carnival Corporation brand. Since P&O Australia is not getting this ship anymore, the Carnival Splendor will be leaving the Carnival fleet and will join P&O Australia. The Carnival Splendor will transfer cruise lines in 2019.
It may be a while before we know more about this 2019 Vista Class ship. In the upcoming future, hopefully Carnival will release some details on the Carnival Horizon's 2018 cruises.
