I also have no status and my agent was able to select seats for me when I booked my DONE3.

Booking though a Travel Agent is often a different experience from when booking though an airline (or using the online tool).

A good TA will be able to select seats on your behalf. When booking without a TA generally once ticketed you need to separately either contact the carriers involved (or enter the manage booking online pages for each carrier) to request/select seating.

I did get seat assignments with my current DONE4, booked with TA. But I also went through each flight with the agent on my other trips booked with AA RTW desk and got seat assignments.

I had this happen again, I debated with myself was it an agent problem, or are AA enforcing a new rule, did I misunderstand, or should I HUCA... The answer HUCA, and the next agent didn't invent her own rules and was fine. This was what the first agent tried to say no to:
OSL-DOH-HKG // HKG-DPS-HKG // HKG-AKL-NAN-MEL-HKG // HKG-SIN-HKG / HKG-JFK

The first AA agent said ""no stopover when going back to Asia"" as soon as I read out the return itinerary, we didn't even get to completing my route - i.e. I double confirmed with him that I could only do MEL-HKG-JFK as a layover of less than 24 hours, no stopover allowed. Anyway, I decided to drop the HKG-SIN-HKG segment to give myself a bit more flexibility on routes and do CMB rather than DPS with a longer return, which helped later on.

Full route booked in the end that worked ok for others to use in the future
OSL-DOH-HKG // HKG-CMB-SIN-HKG // HKG-AKL-NAN-MEL-HKG // HKG-JFK-ORD-ANC-SEA-DOH-OSL
(Return from another RTW) // 1 week CNY Holiday // 2 week Easter Holiday // 2.5week Summer holiday and return

Are there no DONE3/4 fares being filed for CAI? Trying to book some combo of:
CAI-SFO
SFO-SYD
SYD-DPS
DPS-ATH

(obviously adding on ATH-CAI to make sure the flights align)
but online it’s pricing at 14k AUD

I didn’t double check D fare availability, but before I plan exact routes does this seem roughly possible?

Ugh, was it by any chance an agent with a rather nasal voice? I think we must have had the same agent: https://www.flyertalk.com/forum/37194039-post2898.html

I shudder to think of the amount of time that's been wasted and the number of people that have been misled by them.

I don't know if this is bookable, and searching for CAI brought up nothing. Hopefully one of the experts will chime in as this pricing seems too good to be true.

Edit:Upon studying further, I'm guessing the lack of OW flights to this airport (Vueling is the only possibility I might see) might kill it.

Unfortunately you have found the answer to the question, it's not useable due to no OW airlines flying there. The same fare is still filed for the old Alexandria airport (ALY) but not for the new one HBE that actually does have a QR flight.

But it's a good one to keep in your back pocket in case a OW airline decides to fly there in the future.

You might find that BUD is an alternative starting point pricewise if Oslo is too far away.
Good luck with your wandering

If you're using EF to search for ex-CAI RTWs you need to enter the carrier, otherwise you will get a nil return. The prices aren't appealing.

Cheapest DONE3 with BA/CX/QR is USD 7,306, before taxes etc.

I think that OneWorld learned its lesson with this problem at SEZ.

I'm not sure if this is the right thread to ask this...sorry in advanced, but any tips for getting a FF# to show on our boarding passes? AS Sapphire here - our Sapphire status shows on the BA/AY/QF websites, allows us to select seats for free. AA RTW Desk issued ticket.

So far on this ticket, we've never been able to check in online for any of our segments. Today, flew on AY from HEL to ZRH. Checked in at the desk, they printed our boarding passes, but status/FF # did not print out. The agent removed our FF#, re-added it, could see the status, re-printed, and it still didn't show. She said that the FF# wasn't "activating"? I'm not 100% sure what this means. We've had this issue on our Qantas flights as well - the status shows on the Qantas website, but never does when we check-in. Thank you in advance.

I've had this problem before, and despite numerous fixes (calls, sitting at the desk etc.) it really doesn't seem to be able to be fixed - it was particularly a problem with Qantas. My conclusion was that the Qantas system doesn't deal well with tickets with so many legs that have been reissued a few times. Unfortunately I never managed to fix it on the one RTW ticket that had this problem with Qantas - though Cathay was able to fix and add my FFP fairly easily for their leg (after Qantas), as was AA after significant effort from one agent for one leg (before Qantas). So I am afraid to say you may be stuck (or we can both learn what the real fix is), luckily in my case it happened after I had selected seats.

I am in the middle of DONE4 and started to plan for the next one(again), going to start from OSL again and looking for the below routings, not so creative again but it pretty much covers the place i need to go.

OSL-xDOH-HKG-SYD-AKL-HKG-CTS-HKG-HND-JFK-SFO-xDOH-VIE-xDOH-OSL

Was thinking detour the HND-JFK sector as HND-HNL-DFW-JFK to pick up some more miles on the way to JFK but if I travel back to SFO whether this is considered as backtracking between Hawaii and other points in North America even i have a stopover in JFK?

No, it is not considered a backtrack
You will arrive in Hawaii from Asia, then continue on to Nth America, and do not return to Hawaii
So there is no backtrack.
