Jet fuel does not contain lead. Jet fuel is for practical purposes roughly the same part of the dinosaur juice as kerosene and diesel. Jet fuel is burned in turbine and turboprop airplane engines, which comprise the enormous majority of the commercial fleet. Avgas is the stuff with lead in it. Avgas is basically gasoline with lead added as an anti-knock agent and is burned in reciprocating spark ignition engines. Typically these are found in the general aviation fleet.
