Four men who were kicked off a flight from Toronto to New York City in December have filed a federal lawsuit against American Airlines, claiming they were removed from the plane for “looking too Muslim.” According to the lawsuit, the men — two Bangladeshi Muslims, one Arab Muslim, and one Sikh from India who wears a traditional turban — were removed from the plane for no reason other than their appearance and the fact that only some in their party upgraded their tickets. The group’s lawyer noted that the airline didn’t accuse any of the men of inappropriate behavior or of being a security threat, and said the incident amounts to outright discrimination.
