I’m pleasantly surprised I did not miss out on this despite dragging my feet on it. Finally called in an imperfect itinerary yesterday morning. Made a change this morning. And just paid. Knock on wood I did not just jinx it.

Many thanks to FT community for the inspiration and all the know how.

BA are very willing to toss your reservation to whatever agent you have been working on as long as you know their name they would even message them instantly. One agent also admitted that they have a commission structure. However, the problem my arise later: since they do not seem to have centralized unit to deal with these tickets, it may be difficult to change dates. I ticketed RTW with 18 flights on them which may or may more likely not meet fare rules. They were able to price it and ticketed it immediately. When I called to do a date change, there was a pushback about no fee. Agent read the rules and admitted there should be no fee but said they sent it to another department to review. The following day they requested me to call them back and finalized the date change with no fee.
Booking with American is easier because they have a dedicated unit with just under 20 agents in Dallas and the make sure your itinerary meets all the rules to any product whether DONE4 or DGLOB34, then they send it to pricing. After several hours you are able to retrieve the quote online (click "pricing summary") and call the same dedicated phone number to ticket. Note that for ticketing you can also apply any trip credits you have on American in addition to your credit card. Changing the ticket should be easier with AA as the point of contact would be the dedicated team.
So to summarize, these base fares have been creeping up over the last weeks (DGLOB34 is 2976$ today, up from 2944$ yesterday) but they are very much available.

That's almost certainly due to the EGP exchange rate, which has been modestly strengthening against the USD since the initial devaluation

I do hope things work out with your AA ticket.
Do you mind sharing your final itinerary that you booked? (city codes and airlines, pls!) I think that it's good to have a collection of what is acceptable from a ticketing perspective.

I would agree, it's just that fares in EGP are not available on expertflyer.

Ive been tracking the USD equivalent on EF vs exchange rate. They track well.

Erm... Yes they are available in EGP
Simply choose that currency from the picklist of currencies (down toward the bottom of the screen)
Note that doing this is getting EF to convert the published fare into EGP, presumably at the current IATA exchange rate.
If you want to see the currency in which a particular fare is quoted, you need to click on the routing for the fare (!)

Thought I'd re-share mine as well since I made some changes today, this is likely the final itinerary that I'll actually fly with some date changes later on the final DOH-NBO & NBO-DOH-CAI.

CAI-xDOH-CGK (QR)
CGK-NRT (JL)
HND-BKK (JL)
BKK-xHND-xJFK-GRU (All JL code, AA operated on JFK-GRU)
GRU-xDFW-STL (JL code GRU-DFW, AA)
STL-xSEA-DOH (AS, QR)
DOH-NBO (QR)
NBO-xDOH-CAI (QR)

Ended up being
DONE5 Base fare: EGP 145000.00 / AUD 4680.00
Total paid AUD 7,269.00 / US$ 4,738 (not including the $125 change of ticketed points fee)

Maybe I could have done better on YQ with different carriers, but all in all, it's a good deal since I'm crediting to AAdvantage, and all of the those QR and JL segments have a 150% cabin bonus. But TBH I'm not sure I could have done much better on YQ, when I played around with replacing some flights with MH the YQ went up a good bit (like AUD100-300), I don't think changing JL to AA makes a difference, maybe AA trans Atlantic would save a bit but that doesn't interest me, so I'm happy with this price.

I think you've done very well. A DONE4 I've painstakingly managed to get the tool to quote was AUD6750, with no QR or BA.

Did the tool offer you JL codeshares on AA metal or did you have to ask QF to swap those in?

No, the OW tool never offers codeshares, I had to get QF to do that myself.

My understanding is that alone isn't a ticketed points change and would fall under the same exemption as a date / time change. But I have always done them during other changes so not 100% sure on that. The last time I did it was on my CX ticket, but I was able to do it before ticketing since CX doesn't accept payment in the OW tool, you still have to call in for a payment link. Prior to that was another QF ticket and I had an invol reschedule so got free changes together with that.

This is one of the most frustrating things about RTWs and crediting to programs that calculate by revenue... you have to scratch and dig to put everything possible on codeshares that credit by distance. I've had AAdvantage go both ways on AA coded flights so just won't risk it on long segments. JL used to have a few codeshares to South America in the past, I know I've flown to GIG on one right before COVID started but looks like GRU is the only one remaining. I definitely wouldn't have gone to Brazil if I knew I could get distance credit on AA codes, would much much rather have gone to Argentina... but c'est la vie (I'm quite put off by Brazil's return to visas for US, Canada and Australia citizens, but my old 10 year visa is still valid until October). Haven't been to Florianopolis yet so that's an option at least.

It's funny you mention this -- GRU is the only city in South America (I believe) that JL has codeshares for on AA metal. I ticketed a DONE4 and wanted the JL code (mainly because I'm crediting to JMB) but then I would have to go to Brazil instead of Argentina (which is where I wanted to visit). I'm guessing it's because JAL used to operate a 5th freedom route here, but that was dropped a long time ago.
Also agree re: revenue-based mileage programs -- that in itself is a separate discussion but I am fairly certain that there will always be Oneworld programs that cannot afford to go revenue-based, due to regional competition.

Try to retrieve these through fare information in EGP. They are listed as 0 unlike in other currencies. See screenshots attached.

Yes, that's the only remaining JL code I could find. I'd have been content with a QR code as well but didn't find any since they actually fly their own metal to South America. I didn't think to check AY codes, but that would accomplish the same goal.

The 5th freedom route was because of the large Japanese Brazilian population in Sao Paulo, but I know I've flown to GIG on a JL code in very early March 2020 before the world shut down, and I'd swear I saw JL codes at the time to LIM and EZE as well. (Peru and Ecuador also have a good bit of Japanese / Latin population though I don't think I ever checked for GYE / QIO on JL codes)... I could be wrong about EZE and maybe that's why I went to GIG that time but definitely I've seen them for LIM in the past. In both instances though I was going for the longest distance flown on a JL code so had to choose Brazil, Peru is too short of a flight in comparison and Ecuador even shorter.

So from those who've got experience with the OW RTW tickets, how do AA and BA credit for these?
Are they able to calculate the portion of the ticket price applicable to their sectors or do they fall back to % of mileage?
