Louis Miller, who ran Tampa International Airport for 14 years, announced that he will retire this month from his current job of heading Hartsfield-Jackson Atlanta International Airport. Miller, 65, has spent 37 years in the airport business, including the last three in Atlanta, running the world's busiest airport. Miller said he and his wife plan to move back to Salt Lake City, the place where he began his airport career. In 2010, Miller submitted his resignation from Tampa International Airport after conflicts with members of its board of directors. He was succeeded by current TIA chief executive officer Joe Lopano.
