Narrative:

This incident involved a deviation from a received clearance from lax international clearance delivery. Our long range is our primary navigation reference during cruise operations. Our lrn (long-range-navigation) radio was 2 independent king kns 660 types. It has a internal database of (VORTAC, airports, intxns, and a customer defined flight plan database we are accustomed to using. It was brought to our attention by ZAB ARTCC that we were deviating from our filed and cleared route of flight. With further inspection it was revealed that they were correct as our company had filed a non-standard flight plan route which I did not notice during the cockpit preflight duties. The company had filed an airways flight plan route. This 'as filed' airways route was deviated from when our lrn direct routing was flown. The incident occurred due to a lack of vigilance on my part as the first officer. I feel the standard flight plan route was so common that I placed it in the lrn without proper verification. Additionally the change of the initial clearance from LAXX2 to SLI2. Sli departure necessitated me concentrating on editing the initial 3 legs of the flight plan route which may have aided in my mistake of verification of the flight plan routing.
