United CEO Oscar Munoz Thought He Would Be Chairman. Not Anymore.

The company also missed a deadline to explain why a passenger was violently removed from a flight.

Oscar Munoz, the CEO of United Airlines, apparently won’t become the chairman of the company as planned.

Munoz has decided to leave “future determinations related to the Chairman position to the discretion of the Board,” according to a regulatory filing on Friday. He was set to become chairman next year.

The sudden change comes after United’s reputation plummeted following a recent series of public relations missteps, including a video that showed a passenger being violently dragged off a plane.

Senate members demanded the company explain its actions, but United missed an April 20 deadline to do so. The company said its would have answers by April 27.

“We find any further delay in getting necessary answers unacceptable,” Sens. John Thune (R-S.D.) and Bill Nelson (D-Fla.) said Friday in a statement.
