I am currently arranging a Global explorer ticket and part of the routing is SYD-SCL on LA. The flight itself LA800 flies SYD-AKL-SCL as a single flight number

I have held the flight as SYD-SCL which shows up on a mileage calculator as being approximately 7060 miles. When AA calculate the mileage on this sector they are coming up with a value of 7355 which is the summation of SYD-AKL and AKL-SCL

I would have expected that the lower mileage would have been the value that should have been calculated; can anyone confirm which is the correct calculation
