JetBlue paid tribute to a cop killer as part of its Black History Month tribute at JFK Airport’s Terminal 5 — and was forced to apologize for the boondoggle.

Joanne Chesimard, also known as Assata Shakur, was featured in the exhibit just past security for 21 days before a flier noticed one of the bullet points describing her prominence in history.

“Became the first woman to be placed on the FBI’s Most Wanted list after escaping to Cuba from prison where she was serving a life sentence for the 1973 murder of a police officer.”

That police officer was New Jersey State Trooper Werner Foerster who was shot dead by Chesimard at a rest stop on the New Jersey Turnpike.

Shakur was described on the poster as a civil rights activist and also read, “Many people believe Shakur to be a political champion who is innocent of the criminal accusation against her.”

An airline spokesperson told the Post the poster was part of a “ready-made batch of posters celebrating Black History” bought from a third-party and “immediately” removed it last Thursday — the same day the image was tweeted out.

The tweet read: “@JetBlue Rumor has it that you are celebrating Black History month at LGA by celebrating Assata Shakur? She is a convicted cop killer. Please tell me this is not true.”

Any mention of the fugitive, who escaped prison in 1977 and took up political asylum in Cuba, often strikes a nerve with law enforcement. The photo in the airport had been circulating pro-cop websites since Monday.

New Jersey PBA President Colonel Patrick J. Callahan said in a statement Thursday, “appreciate Jet Blue removing the portrait of Chesimard out of respect for the Foerster family, the men and women of the New Jersey State Police, and all of the men and women in law enforcement who made the ultimate sacrifice in the line of duty.”

She remains on the FBI’s Most Wanted list with a $2 million reward and is often brought up in U.S. political relations.

Last year, President Donald Trump demanded the return of Shakur.
