Six Flags Names John Reilly President, CEO

Six Flags Entertainment has hired John Reilly as the amusement-park operator’s new president and chief executive officer, effective Dec. 8.

Reilly’s appointment is the latest twist in the roller-coaster ride Six Flags has been on since it closed a merger with rival Cedar Fair last summer. The company is looking to recover from a bruising summer during which new attractions broke down and attendance and season-pass sales dropped as a result of bad weather.
