CARNIVAL CORP. reported a slight gain in second-quarter profits this year, with strength in Europe offsetting continued weakness in the Caribbean. The world's largest cruise company reported a $390 million second-quarter profit, up from $380 million in 2006, on revenues of $2.9 billion, up 9% from 2006. Carnival lowered its full-year earnings guidance because of higher than expected fuel costs but also said that pricing was improving in the second half of 2007 and into 2008, especially in the Caribbean. During the call Carnival said that it would transfer a ship from one of its 10 cruise brands to the cruise line being formed by a joint venture between Carnival Corp. and German tour operator TUI.
