The NAACP has issued an advisory warning black passengers about a pattern of racist incidents on American Airlines flights. The NAACP cites multiple instances in which African-American women were removed from flights or switched from first class to coach. It also cites an instance in which an African-American man was forced off a flight for responding to the racist comments of fellow white passengers. The NAACP says these events “suggest a corporate culture of racial insensitivity and possible racial bias on the part of American Airlines.” American Airlines says it does not tolerate discrimination.
