I don't know why the example doesn't work. Try this:

rule "ITR Discard"
    when
         req : LowFareRequest(
            $reqTime : requestedDeparture.time)
         itr : AirItinerary( discarded == false )
         flight : Flight(
            departure.time <
                    ($reqTime / 3600000 + 2),
            departure.time  >
                    ($reqTime / 3600000 - 4))
    then
         System.out.println("discard true");
    end
