United Airlines has put Brett Hart in charge of global communications as part of an executive shuffle to accelerate its "momentum in elevating the experience it provides to customers" and continuing operational performance.

The airline's customer satisfaction level took a major hit following the PR crisis triggered when a passenger was dragged off a United Express flight.

Hart assumes the newly created executive VP, chief administrative officer and general counsel slot, where his responsibilities include PR.

He joined United from Sara Lee Corp. in 2010 and stepped in as interim CEO following United chief Oscar Munoz's heart attack in 2015.

Jim Olson, senior VP-corporate communications, now reports to Hart.
