Feb 28 (Reuters) - Spanish travel booking group Amadeus said on Wednesday it expects its revenue to grow by between 11% and 14.5% this year after a solid 2023 boosted by the world travel post-pandemic recovery which allowed it to raise its dividend by two thirds.

"We are optimistic about our growth in 2024 and beyond," Chief Executive Luis Maroto said in a statement.

Adjusted net profit last year jumped 60% from the previous year out of revenue which rose 21%, Amadeus said. As a result it raised its dividend paid out of 2023 profit to 1.24 euros per share, from 0.74 euros the year before.

After the two-year pandemic slump, Amadeus has continued to benefit from a leisure travel boom despite high inflation rates and tightening monetary conditions.

Still, the company signalled a slowdown in the fourth quarter as booking cancellations rose - due to the geopolitical situation in the Middle East - mainly in North America, the Middle East and Africa.

"The recovery in global air traffic during the fourth quarter continued, albeit at a slower pace than prior quarters," the company said.

Amadeus' net profit in the fourth quarter jumped to 248 million euros ($268.46 million) from 181 million euros in the same period a year earlier.

The net result was higher than the LSEG-compiled analyst consensus of 236 million euros.
