The Earth is oblate, i.e., fatter at the equator than at the poles.
The greatest straight-line distance that any two points at sea level can be from each other would be the distance between two points on the equator exactly opposite each other. This distance is the equatorial diameter (twice the equatorial radius) of the Earth which is 12,756.274 kilometers (7926.381 miles).
The greatest great-circle distance that any two points at sea level can be from each other would be the distance between any two points exactly opposite each other on the globe. This distance is one half the Earth's polar (meridional) circumference or 20003.93 kilometers (12429.866 miles).

12,500 miles (half the distance of a great circle, such as the equator).
