DALLAS (AP) American Airlines put an unspecified number of employees on leave for their involvement in an incident in which several Black passengers were removed from a flight in Phoenix, allegedly over a complaint about body odor.

American CEO Robert Isom wrote in a note to staff that the incident was unacceptable.

I am incredibly disappointed by what happened on that flight and the breakdown of our procedures, Isom said in the note this week. It contradicts our values. We fell short of our commitments and failed our customers in this incident.
