Since January, booking volumes at Carnival Corp & plc, the Anglo-American cruise shipping group, for the remainder of the year are running well ahead of last year at lower prices, but the booking window is gradually lengthening, the company said in a statement.

At this time, cumulative advance bookings for the remainder of 2014 are ahead of the prior year at prices below prior year levels.

Group ceo Arnold Donald noted, “We have experienced a solid wave season, with booking volumes up almost 20 % globally surpassing last year’s cumulative advance booking levels, albeit at lower prices.”

“Many guests are booking further in advance, which increases visibility and builds confidence that yield comparisons will turn positive in the second half of 2014. Increased interest across our brands is an encouraging indication that our message is resonating as consumers recognize the strong value proposition and exceptional vacation experiences we provide.”
