First you can lookup airport codes using the "quick links" up in the header.
Second, if you include Cuba on your ticket you cannot include any AA flights, which will limit your options in N. America.
Third, the Pacific islands options are severely limited on a ONE ticket. There are more options on the Global Explorer.
Lastly, no matter where you start a DONE4 and DGLOB34 are the same price. You are looking at a DONE6 based upon your destinations.

A GLOB34 isn't going to work unless you change your routing. http://www.gcmap.com/mapui?P=Mex-scl...OH-JNB-LHR-mex

Skunker, That's a great help. So a DONE4 and DGLOBE34 are the same price from the same start point - but different prices for different start points?

Yes. The price starting in 1 country can be different from another county. Look up the thread at other posts. The airline who issues the ticket, generally airline of the first flight, can make a big difference due to fuel surcharges/fees.

Note that you are limited to 16 segments on all tickets. Makes *ONE5. *ONE6 poor value compared to *ONE4.

Thanks, pandaperth. I'm starting from JNB, which is really the classic origin, isn't it? Also, the ZAR is currently as weak as it ever was to the AUD - there's $200-250 in savings between the fare this time last month - so it's a good time to buy. With Iberia codeshare from MRU-LGW-TFS, the Oneworld website quoted me DONE4 at about AUD$7,200 (70,000 ZAR). The AA desk wouldn't book me on the IB codeshare (only BA), so I'll find out later today what taxes will look like.

Yeah, that's the strange thing - the only available flights on any booking dates between July and October are either through MIA or together through GYE and LIM, which in itself turns a 1 segment flight into a 3 segment flight. I'll be traveling this part of the RTW in 2015, so my actual dates won't be available until next year, so it's only really about getting the itinerary down so the only thing to worry about are the date changes.

There is LAN availability on UIO-SCL right at the end on October 3, although my remaining 5 segments won't be "bookable" for at least a week, which is not a problem in itself, although it's risking the rarity that is this availability. In any case, a US125 fee might outweigh any current currency benefits, so best I book a flight rather than leave it as a surface segment.

FWIW I booked my present AONE4 directly with the AA agency in Capetown. They seemed (arguably) more capable than some of the current agents at the DFW RTW desk, including doing the fare calculation themselves after the rate desk hadn't done the job after three days. (In about half an hour, and accurately afaik.) They take c/c's over the phone with no fuss.

If you enter a short multicity one-way route into matrix.itasoftware.com and specify the carrier as AA+ you'll see if the codeshare is allowed (and the taxes and fees for the flight you tick). It's not someone being snotty - allowed codeshares are in the rules. For example for JNB-LHR to be allowed as AA codeshare the ticket must continue beyond London on AA.

After 7 days and 8 phone calls, was finally able to get a price from the AA Cape Town office. And it was almost accurate to the BA-codeshares quoted on the Oneworld Explorer app - identical YQ charges of 6689 ZAR, in total about $50 more (Iberia codeshare would have been $300 less though). In the meantime, the AUD-ZAR depreciated about $200, so there's added value in skipping MRU and flying JNB-xLHR-wherever on available AA codeshares like most here do - in total $900 less! And I suppose MRU or SEZ can be visited after the latter bookend. The US desk priced the taxes, so booking ahead with the RTW desk and later paying with the Cape Town desk would be save a lot of headache.

I spoke to the AA DFW office once and my experience with them was that they were generally more knowledgeable about the rules but were transfer-trigger happy. I needed to call the US desk on the weekend to extend my hold time and it was sort of amusing because it became a circular thing where one department would transfer me to the other department and it became a back-and-forth between the RTW desk and a general reservations desk. It was a raffle, so eventually I got hold of someone who would help me, who also informed me that Cape Town booked me into the wrong booking class for my AB Economy segments.

A few issues: At least two operators at the Cape Town desk are under the impression that LAN Argentina and LAN Ecuador cannot be booked on a RTW. And another two operators are under the impression that if D isn’t available, you must be booked in Y (It’s actually L, but if W is available, it’s that).

But they had access to flights unavailable on the OW app (including the regular EZE-GYE and GYE-SCL), so I had no way of booking this online if I wanted to.

FWIW I did not book a 16-segment AONE4 with Capetown, rather a simple 4-segment trip that got me on codeshares to the U.S. (presumably the only way to get AA codeshares from JNB) and back around. I didn't mind the $125 change fee I was going to have to pay to flesh out the trip because among other things I was worried about a possible price increase so I wanted to book 'NOW!' and didn't really know all the segments I wanted.

(Also serendipitously grandfathered myself on the two-extra-segments-per-continent benefit that disappeared on 1 July. )

Indeed. In fact, in the last week the Oneworld Explorer has stopped quoting me a base fare of 58,940 ZAR for most of my JNB-originating flights involving South America. It's now quoting 117,880 ZAR for everything except my oldest saved itinerary (and USD11,361 for AA-codeshares). That's just base fare.

So hopefully that's a bug and not a sign of another price increase.

I just went down to the MH ticket office at KL Sentral to get an MH operated flight changed on a CX issued DONE3.

Not only did they refuse to even look at making any changes, but they told me to talk to SQ.

Now, I've had a number of xONEx tickets in the past issued by a mix of QF, AA and CX and every time I've needed a change done, QF, AA, BA, CX, AY and JL have done it without complaints - regardless of who was operating the flight in question or who issued the ticket.

I think MH needs more training.

Qatar's love of married segments is causing me grief.

I'm trying to book DME-DOH-JFK as part of a DONE4, departing DME on the (second) last departure (about 7pm), nine-odd hour layover in DOH and onto JFK. However, despite ample D availability on both flights, it's only possible to book the earlier DME-DOH departure, making for a greater than 12 hour layover.

Is there anyway around it?

Would it be possible to book the last DME-JFK departure, create a stopover in DOH, then book DOH-JFK , and then after booking, attempt to move the DOH-JFK to one day earlier? I suspect the system will reject it but I thought if I made the change 'from the back end' (by moving the DOH-JFK flight rather than the DME-DOH flight) I might have a chance.

Are you trying to book as QR flight number?
Is an AA codeshare available on the same flight ?

Edit: Answer in part
DOH To New York (JFK), NY, US (JFK) 8:05 AM 2:05 PM AA7973+ 777 14h00m
Operated By Qatar Airways

Each airline will not be getting much $ from a DONE* fare

Brilliant. Thank you for that.

The codeshare doesn't seem to appear in the oneworld booking tool but it obviously exists so I'll try getting AA to input the AA codeshare and see if that works.

And better earning in the AA ffp. Do not put QR flight numbers to the QF ffp:- very low earning.

That worked perfectly. Thank you.

Glad to help.
Assuming you are collecting AA miles, AA codeshares can be very beneficial.

Even to QF ffp AA marketed are better than most other carriers
For example to QF freq flyer program for QR marketed flights
0.75 points/mile CDIJ Business :td: :td:
1.00 points/mile AFP First :td: :td: :td: :mad:

And I like a good red ;)
