Is this allowed on a AONE4 if I pay $1,000 for two extra segments:

1) HKG-PEK KA902
2) PEK-SHA (open jaw)
3) PVG-HKG KA803
4) HKG-MNL CX903
5) MNL-HKG CX900
6) HKG-JKT CX777
7) JKT-HKG CX776

???

Yes, but it will use 8 (not 7) of your permitted 16/20 segments.

Why is it not 7 segments. Why is there a penalty?

Because you have 8 segments the way you wrote it.

1) HKG-PEK KA902
2) PEK-SHA (open jaw)
3) SHA-PVG surface
4)3) PVG-HKG KA803
5)4) HKG-MNL CX903
6)5) MNL-HKG CX900
7)6) HKG-JKT CX777
8)7) JKT-HKG CX776

Apparently, you may have meant:

1) HKG-PEK KA902
2) PEK-PVG SURFACE
3) PVG-HKG KA803
4) HKG-MNL CX903
5) MNL-HKG CX900
6) HKG-JKT CX777
7) JKT-HKG CX776

That would be unbelievable if you're saying there's a segment penalty to fly into the domestic airport in Shanghai and out of the international one.

Why isn't the open jaw written PEK-PVG...I think I just found my own answer...it would be.

This isn't unbelievable. Coterminals count as segments now. Fly into LHR and out LGW it is a segment. Fly into LGA out of JFK that is a segment.

Right, but seeing that I am making my own way to Shanghai, I can technically just as easily "open jaw" for these purposes into PVG as SHA...so the ticket would read PEK-PVG open jaw, and then PVG-HKG on KA. The fact that I am actually flying PEK-SHA on China Southern isn't relevant, as it's not part of this ticket.

Actually the ticket will be:
1 - HKG-PEK
2 - ARUNK (arrival unknown which uses a segment)
3 - PVG-HKG
4 - etc...

You can't add segments in the continent of origin.

That's fine as long as it doesn't count as two segments, one into SHA and one out of PVG! Thanks!

You can find flights from Shenzhen (SZN) to/from Beijing and Shanghai for much, much less than the additional $1,000 you're considering here....and thereby save all 3 of the sectors as well.

There are 2 very convenient services from Hong Kong to the airport in Shenzhen ---- a new nonstop bus service from the Kowloon MTR station that runs every 20 minutes during the day (via a new customs crossing that is astoundingly empty and stress-free), as well as the well-known ferry service ---- and from SZN there are flights on a half-dozen or so airlines with very, very competitive prices. For example, you can generally find a SZN to PEK or SHA to SZN oneway for CNY 700. If you're concerned about segments, this could save you 3 --- as well as at least $500....
