This question also came up in the Delta forum, and I posted my routing there to learn that I had to account for "ground" travel between open-jaws, but this still didn't seem get it quite at what Delta said it was.

Here is my itinerary:

JFK-ATH (DL132) - Stopover
ATH-CPH (Ground) - Stopover
CPH-CDG-BKK (AF2351/AF174) - Stopover
BKK-NRT (NW28) - Stopover
NRT-PEK (NW11) - Stopover
PEK-ICN-SYD (KE880/KE811) - Stopover
SYD-CNS (Ground) - Stopover
CNS-GUM (CO903) - Stopover
GUM-NRT-LAX (CO961/KE1) - End trip

Adding this up using the great circle mapper, I got 33,016 including ground segments.

Delta said it was 32,355 - so its an error in a good direction for me, but I am still confused as to why they are not adding up.
