JetBlue Airways said CFO Ed Barnes, who had been with the New York-based LCC since 2006, has resigned.

Treasurer and senior VP Mark Powers "will serve the company as CFO effective immediately for an interim period as the company conducts a search for a new CFO," the airline said in a statement. Powers joined JetBlue in 2006 as treasurer and VP-corporate finance.

"Under Ed's leadership, our company has benefitted from a stronger financial discipline, allowing us to plan a sustainable growth strategy," president and CEO Dave Barger said.
