The best available evidence indicates that approximately $300,000 was deposited into the
hijackers’ bank accounts in the United States by a variety of means. Just prior to the
flights, the hijackers returned about $26,000 to one of their al Qaeda facilitators and
attempted to return another $10,000, which was intercepted by the FBI after 9/11. Their
primary expenses consisted of tuition for flight training, living expenses (room, board and
meals, vehicles, insurance, etc.), and travel (for casing flights, meetings, and the
September 11 flights themselves).
