There was no luggage or passengers personal effects at the Pentagon crash site.
There were reports of personal effects, later returned to relatives. A couple of examples.
"During an interview earlier this week, Koch delicately handled eerie mementos of the crash found during cleanup: Whittington's battered driver's license... a burnt luggage tag and a wedding ring lie on a book dedicated to those lost in the events of Sept. 11, 2001. The wedding ring belonged to Ruth's daughter and the luggage tag belonged to one her granddaughters."
“Suzanne Calley died aboard American Airlines Flight 77 when terrorists hijacked the plane and sent it crashing into the Pentagon... Rescue crews were able to pull Calley’s body from Flight 77’s wreckage.
Jensen [Calley’s husband] spent last year’s anniversary of the national tragedy in Washington, D.C. There, a Pentagon official - assigned to Calley’s family as a liaison - gave Jensen his wife’s wedding ring, which had been recovered from the plane.”
