Narrative:

Flight london gatwick (lgw) to cincinnati (cvg). Company filed us after the ocean crossing. Na route 2o2 yri dct plb J29 jhw ape blunt 4 STAR cvg. Na 202 is direct yri as the common portion of the route. But the non common portion to cvg after yri is completely different than what we filed. We knew this and discussed this amongst ourselves and decided we would clarify the clearance after passing 50 degrees west when we normally receive this part of clearance. I was on my rest break when we passed 50 degrees west and received clearance to cvg via na 202. The other crewmen did not question nor clarify the clearance or change the flight plan in the FMS. When I returned to cockpit from my rest period we were approaching yri. I never asked about the clearance. As we passed yri we turned towards plb. A few mins later ATC called asking how we were cleared. I realized our mistake and after some discussion with ATC we were reclred as we had originally filed. I realize that we were wrong, however, when the company dispatcher files for a clearance, if they would either use the entire na route both common and non common or else not use the na route designation at all, the possibility of a mistake like this would be greatly reduced.

Title: ACR WDB TRACK DEV ON NA RTE AFTER OCEAN XING.

Narrative: FLT LONDON GATWICK (LGW) TO CINCINNATI (CVG). COMPANY FILED US AFTER THE OCEAN XING. NA RTE 2O2 YRI DCT PLB J29 JHW APE BLUNT 4 STAR CVG. NA 202 IS DIRECT YRI AS THE COMMON PORTION OF THE RTE. BUT THE NON COMMON PORTION TO CVG AFTER YRI IS COMPLETELY DIFFERENT THAN WHAT WE FILED. WE KNEW THIS AND DISCUSSED THIS AMONGST OURSELVES AND DECIDED WE WOULD CLARIFY THE CLRNC AFTER PASSING 50 DEGS W WHEN WE NORMALLY RECEIVE THIS PART OF CLRNC. I WAS ON MY REST BREAK WHEN WE PASSED 50 DEGS W AND RECEIVED CLRNC TO CVG VIA NA 202. THE OTHER CREWMEN DID NOT QUESTION NOR CLARIFY THE CLRNC OR CHANGE THE FLT PLAN IN THE FMS. WHEN I RETURNED TO COCKPIT FROM MY REST PERIOD WE WERE APCHING YRI. I NEVER ASKED ABOUT THE CLRNC. AS WE PASSED YRI WE TURNED TOWARDS PLB. A FEW MINS LATER ATC CALLED ASKING HOW WE WERE CLRED. I REALIZED OUR MISTAKE AND AFTER SOME DISCUSSION WITH ATC WE WERE RECLRED AS WE HAD ORIGINALLY FILED. I REALIZE THAT WE WERE WRONG, HOWEVER, WHEN THE COMPANY DISPATCHER FILES FOR A CLRNC, IF THEY WOULD EITHER USE THE ENTIRE NA RTE BOTH COMMON AND NON COMMON OR ELSE NOT USE THE NA RTE DESIGNATION AT ALL, THE POSSIBILITY OF A MISTAKE LIKE THIS WOULD BE GREATLY REDUCED.
