Two flight attendants called the American Airlines reservation desk during the hijacking. Betty Ong reported that "the five hijackers had come from first-class seats: 2A, 2B, 9A, 9C and 9B." Flight attendant Amy Sweeney called a flight services manager at Logan Airport in Boston and described them as Middle Eastern. She gave the staff the seat numbers and they pulled up the ticket and credit card information of the hijackers, identifying Mohamed Atta.
