August 25-27, 2001: Hijackers Alhazmi and Almihdhar Buy 9/11 Plane Tickets Despite Presence on Watch List

Hijacker Khalid Almihdhar buys his 9/11 plane ticket on-line using a credit card; hijacker Nawaf Alhazmi does the same two days later, and also buys a ticket for his brother Salem (see August 25-September 5, 2001). Both men were put on a terrorist watch list on August 23 (see August 23, 2001), but the watch list only means they will be stopped if trying to enter or leave the US. There is another watch list that applies to domestic flights that some of their associates are on, but they are only placed on the international watch list (see April 24, 2000). Procedures are in place for law enforcement agencies to share watch list information with airlines and airports and such sharing is common, but the FAA and the airlines are not notified about this case, so the purchases raise no red flags. [Los Angeles Times, 9/20/2001; US Congress, 9/26/2002] An official later states that had the FAA been properly warned, “they should have been picked up in the reservation process.” [Washington Post, 10/2/2002] On September 4 and 5, 2001, an FBI agent will attempt to find Alhazmi and Almihdhar in the US, but will fail to conduct a simple credit card check that should have revealed these purchases (see September 4-5, 2001).
