As for AA's mileage creep, the simple explanation could be that they've changed the reference Earth model (e.g., a sphere to an ellipsoid, or Clarke 1866 ellipsoid to WGS84 ellipsoid, or whatever) used in the great circle calculation.
Several times for each mileage pair pair? (AA systems are not up to plate tectonics; give it a decade or so. )
