The NAACP has issued a national travel advisory for American Airlines, following what they say is a pattern "troublesome conduct" by employees that could put black travelers at risk.

The warning, sent out Tuesday, cites "a pattern of disturbing incidents reported by African-American passengers, specific to American Airlines." Among the alleged incidents: a black women was removed from a plane after asking that her stroller be retrieved from baggage; a black man was forced to give up his seat after responding to discriminatory comments from two white passengers; and a black woman was ordered off a flight by the pilot after complaining about having to change seats.

"In light of these confrontations, we have today taken the action of issuing national advisory alerting travelers—especially African Americans—to exercise caution, in that booking and boarding flights on American Airlines could subject them disrespectful, discriminatory or unsafe conditions," read a statement from the NAACP. "This travel advisory is in effect beginning today, October 24th, 2017, until further notice."

The advocacy group also called for a meeting with the company's leadership to discuss the alleged discrimination. "Until these and other concerns are addressed, this national travel advisory will stand," said Derrick Johnson, newly elected president and CEO of the NAACP.

American Airlines has since responded to the allegations, and agreed to meet with the leaders of the NAACP. "We are disappointed to hear about this travel advisory as our team members—a diverse community of gate agents, pilots, and flight attendants—are proud to serve customers of all backgrounds," American Airlines CEO Doug Parker said in a statement.

The Dallas Morning News notes that the advisory comes just one week after Tamika Mallory, a New York activist and co-chair of the Women's March, says she was kicked off an American Airlines flight following a dispute with a pilot over her seat assignment.

"It definitely was white male aggression. I was singled out, I was disrespected, and he was trying to intimidate me," she told the Daily News after the incident. "I was discriminated against."

The NAACP is fielding stories from the public about other travel irregularities, aboard American Airlines elsewhere, which you can report here.
