In 2011 5008 miles, ISL - JFK on a DL 767. I'm assuming it was a 300. Time was 11:43
I was also on 767-300's mid 2011 LO JFK-WAW and WAW-JFK: 4259miles
IIRC The 300's were previously operated by Zoom air and still had Zoom's markings on the interior and projected onto the video screens. (If not Zoom, some other defunct LCC)
