Trying to complete my flight history and have gone back and found an old boarding pass from 2010 for JL51 NRT-KIX. Most sources I've found show it was operated by a 737-800, but I was seated in 58C. I'm thinking it may have been operated that day by a 747-400? I would've came in on JL17 YVR-NRT on a 747-400. Any chance anybody remembers or has a copy of an old JAL timetable from 2010?

Thanks in advance!
