American Airlines named Ganesh Jayaram as its chief digital and information officer. He succeeds Maya Leibman, who had been the carrier’s CIO since January 2012. Jayaram was most recently CIO at Deere & Co., where he spent more than 15 years. He has also worked at Danaher Corp., Canon USA and Boston Consulting Group.

JetBlue Airways has appointed Steve Olson as vice president of system operations. He has been serving as managing director of the integrated operations center for American Airlines and spent nearly two decades with that carrier — as well as with US Airways and America West.
