REVOLVING DOOR: Airline industry leaders who were once under the Federal Aviation Administration now sit in top positions at the agency. Many former FAA officials and congressional aides have found lucrative jobs in the industry or with its lobbying groups.

WINNINGS: What the airline industry wants from Washington it often gets. Deregulation and multibillion-dollar government bailouts are among the industry’s major victories recently.

PROBLEMS NOW: The industry is under scrutiny after two federal safety inspectors accused FAA officials of ignoring maintenance and inspection problems at Southwest Airlines.
