Aviation Week -- JetBlue announced yesterday that Russ Chew is leaving the airline after a little over two years as its COO (and less than two as its president). Chew joined the airline in March 2007, when it really needed someone with Chew’s experience and expertise to add credibility to its efforts to improve its operations. At the time, the airline was working to recover its service reputation after a Valentine’s Day, ice storm-related operational meltdown at its Kennedy hub. Chew had been COO of the FAA for four years, and spent 17 years in American’s operations and planning units before that.
