On September 10, 2001, Suqami shared a room at the Milner Hotel in Boston with three of the Flight 175 hijackers, Marwan al-Shehhi, Fayez Banihammad, and Mohand al-Shehri.

On the day of the attacks, Suqami checked in at the flight desk using his Saudi passport, and boarded American Airlines Flight 11.
 At Logan International Airport, he was selected by CAPPS, which required his checked bags to undergo extra screening for explosives and involved no extra screening at the passenger security checkpoint.

An FAA memo, circulated in February 2002, claimed that Suqami shot passenger Daniel M. Lewin (Seat 9B), co-founder of Akamai Technologies and a former member of the Israeli Sayeret Matkal, for attempting to foil the hijacking.
While based on the frantic phonecall received from a stewardess of the flight, the report has been a matter of some controversy, since both the FAA and FBI have strongly denied the presence of firearms or guns smuggled aboard.
It is now believed that Suqami stabbed Lewin as he attempted to intervene in the hijacking.
