Normally this wouldn’t be all that dramatic of a deployment, however they will be sending some of their best hardware to Asia to compete with the Quantum of the Seas.
Costa was originally scheduled to just sail the 1996-built Costa Victoria and 2000-built Costa Atlantica. Now they will be joined by the 2007-built Costa Serena which can carry 3,700 pax every week. Also representing the Carnival Brand will be the 2004-built 2,670 pax Sapphire Princess.
Asia used to be where lines would send their oldest and smallest ships. However given the strong economies of China, Korea and to a slightly lesser extent Japan, lines have been flocking there lately. Of course everything was scrapped when Royal Caribbean shocked the industry by sending the Quantum of the Seas there full time.
