The New York and London-listed cruiseship giant said it now predicts adjusted earnings per share (EPS) of between $1.84 and $1.88, up from a prior estimate of $1.60 to $1.75.

That would also represent a sizeable increase on 2013 earnings, when Miami-based Carnival delivered adjusted EPS of $1.58.

Carnival also boosted expectations of net yield growth. The company had previously told investors that it expected to see the measure, a key financial metric for the cruise sector, show a slight decline this year.
