So when you say path - i assume you mean left and right deviation , when Jet streams refer to elevation.
Why does it take longer to fly from London to NYC then it takes to fly from NYC to London?
i was referring to elevation, because i understand all 3 dimensions.
your explanation still is not an answer. calculating the speed in a jet stream you would still come up short given your map, because the distance grows by flattening it out. jet streams are a known and used part of flying, that's not an answer to how they cover MORE miles due to flattening. whether on a flat or round earth jet streams are used, which you're ironically using as proof yet again just like the flat horizon.
