In Wolfram's own screenshots, even WolframAlpha gives two different inconsistent answers for the distance between Chicago and Tokyo.

In the WolframAlpha query, it gives 6313 miles

But in the `GeoDistance[Chicago, Tokyo]` query, it gives 6296 miles

Is there something different about the two queries? Is one Haversine and the other Eucledean? Or does one compare city-centers and the other compares minimum edge-to-edge distance?
