The most direct was the only answer I got.... So I asked for an example.
Then they said it must be trough the US.... I found seats AKL-SYD-SFO-IHA-GRU. But also these was not valid.... Looks like they have any pressure from somewhere....

Well I don't see what kind of exception that would be? RAR, AKL or SYD are on the same Zone... so don't get it why the route should not be allowed.

I don't know exactly how it works but there is such a thing as maximum permitted mileage - MPM.

RAR-GRU is 7006 miles.
RAR-AKL-PER-JNB-GRU is 14999 miles.

It wouldn't surprise me if your proposed itinerary falls foul of technical ticketing rules which require it to be ticketed as more than one ticket. You may simply have to accept that this itinerary won't work.

How do you get from SYD to JNB? SYD-AKL-PER-JNB??

Yes I see the SAA flight is in fact a codeshare QF operated flight....looks like you're up a gum tree then.

Hopefully they rejected it!

You did not really think they would approve this routing???

GRU-SFO is 6472 mi
GRU-IAH-SFO are 6537 mi
GRU-JNB-BOM-BKK-AKL-KIX-SFO are 27715 mi...

Did you ever try to get a ticket SFO-ORD via NRT-FRA-JFK for the price of a north american domestic one-way?

The point is that there aren't any routes going from Zone 9 to Zone 4.
So actually they should never publish that possibility. The only way to get from Zone 9 to Zone 4 is either trough the US or SA. And I agree the routing is not that direct.... however only OW is offering good connections. Such as PPT-SCL-GRU or SYD-SCL-GRU or AKL-SCL-GRU

Is this a valid route?
 

How about this?

PVG ( ICN ) MNL
stop
MNL SIN LHR

I'm wanting to book a redemption in business.

Is SYD -ICN (stopover) ICN - LHR a valid route with OZ?

Otherwise I have the choice of TG and SG, as I've been to both Bangkok and Singapore before, I'd prefer a stop over somewhere new!

Any comments about OZ welcome, I've not flown them before!

Thanks ;)

Yes, and you'll enjoy OZ - a very pleasant service (Asian standard, lots of personal attention) and in my experience better than TG, probably slightly worse than SQ but more personal. Seoul is also an interesting city to visit and I've really enjoyed myself in the wider Korea (depending on how long you'd like to stay for). The city has a lot of culture, then a tour of the DMZ is also a particularly unique experience - make sure that you choose a tour that includes the JSA.

Final tip - have a look on the OZ website around which flights from London are gaurenteed to have their new beds (not all of them are, at the moment), and check out the relevant forum on flyertalk for a discussion of those beds.

You are thinking of SFO as the outbound endpoint. Rather Queenstown was the outbound end point. The stop over in SFO could have been dispensed with. The problem was that the route has to be published by an airline, which I don't believe really should be a requirement.

My beef is that GRU-JNB-PER-AKL one-way is not permitted.

Award Routing Advice
 

Before I enter the fray with ICC or UK-TCC could some kind DC expert advise if following is acceptable.

SIN/BKKx/RGN/BKKx/CEI based on one way area 7 to area 7 with Stopover in RGN

Many Thanks

Does anyone think I'll be able to get EDI-LHR-LIS-BCN past ticketing? It's the most direct route I can think of now that LH are out of the equation.

I have managed to get BCN-LIS-MAN before so yours is a very similar route with only a EDI segment added on.

If you mean you wanna do BKK-RGN-BKK-CEI then you have no chance. They will not allow two same airports on a one way routing.
