Mexico's Grupo Aeroportuario del Sureste says it expects annual revenues of $11 million to $17 million from managing San Juan airport, the largest in Puerto Rico and the Caribbean region.

The 40-year contract to operate Luis Muñoz Marin International Airport was awarded last July to ASUR and 50-50 joint venture partner Highstar Capital.

"It's a good business," Agustin Arellano, head of ASUR-led consortium Aerostar Airport Holdings, told San Juan's WKAQ radio, adding that the new management has no plans to eliminate jobs at the terminal.

"The San Juan airport will become a world-class one," he said, criticizing the previous administrators for cutting corners on maintenance.

Aerostar Airport Holdings plans an initial investment of $200 million to upgrade the facility, Arellano said.

Unions, backed by some elements in the governing PPD party, want the legislature to name a commission to investigate the circumstances of then-Gov. Luis Fortuño's awarding of the airport contract.

But the new governor, PPD leader Agustin Garcia Padilla, said his administration will honor the pact because to do otherwise could scare off potential foreign investors in Puerto Rico.

ASUR's deal to operate the airport must still be ratified by the U.S. Federal Aviation Administration.

Luis Muñoz Marin International handles over 8.5 million passengers per year and is served by more than a dozen airlines. The airport has two runways measuring three kilometers (1.9 miles) and 2.5 kilometers in length, respectively, and three passenger terminals. EFE
