Another airport official steps down

Hartsfield-Jackson International Airport's deputy general manager, Mario Diaz, is stepping down from his position just a couple of months before his boss, Ben DeCosta, is scheduled to leave the helm of the airport.

Diaz, who has held the job since 1999, is leaving for a position in Houston, DeCosta said. Diaz was not available for comment on Tuesday.

The Houston Airport System said it is planning to announce a new director of aviation on Wednesday. The Houston Airport System includes three airports -- George Bush Intercontinental, William P. Hobby and Ellington Airport.

Before DeCosta become head of Hartsfield-Jackson in 1998 and brought Diaz on shortly after, they both worked at the Port Authority of New York and New Jersey.

Atlanta Mayor Kasim Reed has said he will conduct a national search for DeCosta's replacement. Reed said earlier this year he had complete confidence in Diaz during the interim.

Meanwhile, DeCosta said he will be doing consulting work after he leaves his position.
