UPDATE 1-Cruise operator Carnival's profit beats on higher ticket prices

(Adds details; updates share)

Sept 26 (Reuters) - Carnival Corp, the world's largest cruise operator, reported a better-than-expected quarterly profit on Tuesday, helped by an uptick in ticket prices and higher spending by passengers on board its ships.

The company's shares were up 4.1 percent at $66.11 in morning trading.

Carnival's efforts to promote on-board experiences to travelers helped drive a five percent rise in cruise ticket pricing, Carnival's Chief Executive Arnold Donald said in a statement.

The Miami, Florida-based company said temporary port closures due to hurricanes led to voyage disruptions, resulting in an estimated 10 cents to 12 cents drop in earnings in the fourth quarter.

"Hurricane disruption compounded by Maria has led to much more disruption and uncertainty in the near term than the cruise industry has seen from hurricane seasons previously," UBS analyst Robin Farley said in a pre-earnings note.

Net revenue yields, a closely watched metric that measures spending per available berth, rose 5.5 percent in the third quarter on a constant currency basis.

Revenue rose 8.2 percent to $5.52 billion. Analysts on average had expected $5.39 billion, according to Thomson Reuters I/B/E/S.

The company's net income, however, fell to $1.33 billion, or $1.83 per share, in the third quarter ended Aug. 31, from $1.42 billion, or $1.93 per share, a year earlier.

A $392 million charge related to the write down of some assets in Australia impacted net income in the reporting quarter, Carnival said.

Excluding one-time items, Carnival earned $2.29 per share, topping the analysts' average estimate by 9 cents.

The company now expects adjusted earnings for the year ending November to range between $3.64 and $3.74 per share, up from its prior forecast of $3.60 to $3.70 per share. (Reporting by Uday Sampath in Bengaluru; Editing by Sriraj Kalluvila and Arun Koyyur)
