This warning comes after multiple passenger interactions with American Airlines that the NAACP calls a pattern of disturbing incidents. They include an African American man forced off a flight after an incident with two white passengers and an African American woman who purchased two first-class tickets and was moved to coach while her white companion was allowed to stay in first class.
The NAACP says these examples and a couple of others suggest racial bias and cannot be dismissed as normal or random.
American Airlines responded to the advisory with an invitation to the NAACP to meet saying: "We are committed to having a meaningful dialogue about our airline and are ready to both listen and engage."
There is no word on when that meeting will take place.
