One of the city's most prominent Muslim leaders claims he was prevented from boarding two American Airlines flights en route to a conference on Islamophobia last week because of his appearance. Imam Al-Amin Abdul-Latif — who heads the Majlis Ash-Shura, or Islamic Leadership Council of Metropolitan New York, a representative body that includes dozens of area mosques — said he was twice denied by officials when he tried to board an American Airlines flight from La Guardia to Charlotte, North Carolina, on Friday to attend a conference on Islamophobia.
