Paul Ciancia, 23, was represented by a public defender and did not enter a plea, NBC News reported.
Prosecutors said Monday the hearing, at the West Valley Detention Center in Rancho Cucamonga, where he is being held, was intended to make sure Ciancia was "apprised of his rights, has seen the criminal complaint filed against him and has an attorney," the Los Angeles Times reported.
Ciancia is charged with killing Transportation Security Administration agent Gerardo Hernandez, 39, and wounding three others during the Nov. 1 rampage before LAPD officers arrived and shot him.
Investigators said Ciancia had written in a note he wanted to kill TSA agents and "instill fear in their traitorous minds."
If convicted on charges of killing a federal officer and commission of violence at an airport, Ciancia could be sentenced to death or life in prison without the possibility of parole, the Times said.
The shooting spree halted flight arrivals at LAX for much of the day with numerous flights delayed and connections missed.
