If I add KHV-OVB-DME it will be 17 flights.

So it is... I missed the IPC flights when I checked.
That's also where you have a problem. -UIO-GPS-GYE-LIM-SCL-IPC-SCL- is 6 flights in South America. You're only allowed 4.

Buzz! Wrong!
The Global Explorer rule differ from the Oneworld Explorer rules in this respect
The Global Explorer rule is maximum of 4 stopovers per continent, not a maximum of four flights

Why?

Flights and stopovers
- Select up to 16 flight segments on your round-the-world itinerary. Travel between two airports by surface transportation will count as one flight segment.
- Each tier includes the following stopover allowances:
Tier 1 – Minimum two. Maximum five (including a maximum of two within a region).
Tiers 2, 3 and 4 – Minimum two. Maximum four within a region.
All tiers – A maximum of two stopovers are permitted in the region of origin.

I can have more than 4 flights/segments is the South America region.

There's no such limit on Global Explorer fares that I can see.

Edit - ooops - I'm getting slow in my old age! :D

But now, how I can explain to airlines that my all route is ok?

And now, how I can explain to airlines, that all my route is ok?

Great circle mapper shows the total mileage as 34501, so this is a 39000 GE as far as I can see.

Is it a problem?
I can choose LGLOB39 39000 (ECONOMY ONLY)

Sorry Olga, but in my opinion your route is not OK
Airlines look for the most restrictive rules and I think they have you on this one:This rule implies you must return to the TC area in which you started.

The problem is Russia is split between two TC areas - European Russia in TC2 and Asian Russia in TC3.
Start in European Russia, you have to return to European Russia.
In other words start in TC2, you have to return to TC2.

Also, are you trying to keep your mileage under 34,000? Your itinerary is just over; remember surface segment miles have to be included - dme-mad-pty-mga-mia-uio-gps-uio-lim-scl-ipc-scl-syd-bkk-nrt-khv
Forget this comment - I see you're thinking of an LGLOB39, allowing you up to 39,000 miles

No, not a problem - just checking that you know that the surface sector has to be counted, which pushes it over 34000 miles.

It looks OK to me, although with Russia being split between TC3 and TC2 I can see that there is some slight ambiguity. It's the only case in which you don't start and end in the same TC, although the fact that the start and end are in the same country and that is explicitly allowed would seem to make it fine for me. Maybe try to get a different airline to ticket it?

Would this work for you?
dme-mad-pty-mga-mia-uio-gps-uio-lim-scl-ipc-scl-syd-nrt-bkk-ovb-dme

No,because I'm from KHV:)

So maybe you can start from somewhere just East of the Urals - in other words in Asian (TC3) Russia? Such as:
ovb-dme-mad-pty-mga-mia-uio-gps-uio-lim-scl-ipc-scl-syd-bkk-nrt-khv

Also, I have just remembered this from the fare rulesQF has a codeshare on TN PPT-AKL

So you could fly IPC-PPT-AKL-SYD instead of IPC-SCL-SYD

It does take one extra segment, but you get Tahiti and New Zealand
