On the morning of 3rd Jan I was on board KE035 ICN-ATL. Over Nashville we started our descent and I noticed parallel to us, and flying in a south easterly direction, there was a JAL 744. I wondered where this flight was going. Not being familiar with JAL schedules I looked at the timetable to see if they had flights to Atlanta or Miami, but they don't
Also, it definitely wasn't a cargo aircraft. I took a picture of it and got quite a clear photograph.
The time was 0900 Eastern.
Any help would be appreciated.
