What class are you interested?
Based on the latest currency exchange rate, I found this on EF:
DONE3 ex-TYO is less than ex-OSL
DONE4, 5 & 6 ex_OSL is better

Thank you! I guess I should have looked at it myself. I'm not lazy, I swear! I just sort of remembered that back in the day (like, ten years ago) sometimes RTWs were cheapest when purchased in out-of-the-way locations. TYO and OSL are much easier.

BTW, allset2travel very nice site and photos! ^^

Yes, most of us on this board remembered and many had taken advantage of such fares. Personally, I started ex-AMM DONE3 by using then valid "Canadian Exceptions"; and couple of ex-JNB (DONE4 & DONE5 respectively) due to currency exchange working in my favor! Currently in the middle of flying an ex-NRT DONE3 which will be nested with an upcoming ex-OSL DONE4.
Oh, those good old days!

Thanks for the compliments re my travel photo site.

Before I knew better, I did one AONE3 ex-U.S. Then I joined FT and smartened up. In the early years (for me), I bought them directly from BA at MRU. There was no central faring; and the BA staff at the station didn't really understand the rules. This went on for a number of years, until South Africa became the place; and I was buying from Mindpearl. The BA flights were overnights from LHR arriving early morning, then departed South Africa in the early evening, so they just sat in South Africa all day. I had a number of single days at both JNB and CPT and did some great sightseeing. At that time, a close friend was chairman of a consulting company which had offices seemingly everywhere; and his J'burg office found an excellent tour guide for me.

I had one ticket ex-South Korea; I can't recall clearly right now, but it may have been the 10 year anniversary 10% discount year. Then I stopped buying them until ex-SEZ last year.

I agree, those were the days.

DXB F availability much less since A class abolished
 

I wonder if it might be a point-of-sale issue? Try setting the PoS in EF to match the starting point you are using in the OneWorld tool. Also try calling the AA RTW desk to see if they can book a sample itinerary that the OneWorld tool shows as not available (not to necessarily have them book it, but just to see if they can).

There's your first problem.

This is a rank amateur question, but I didnt see it on the wiki.

Do I call the airline who I paid for the flight with or the airline who I am flying with if I want to make a change of time and also change city.

Have you already flown the first flight on the ticket?

No I haven't

What ticket did you buy? An xONEx?

If you have not yet flown the first flight, then any changes to "ticketed points" (the set of airports you touch) will force a re-fare at the current price. If the base fare for your ticket has not changed, then this is nothing to be concerned with, although your taxes and fees might be more or might be less. If less, you do not get a refund. If more, you pay the extra. You should call the airline/agency that issued your ticket in this situation (although any OneWorld airline could handle it, many won't know how or won't want to, although the AA or BA dedicated RTW desks would handle it).

Thanks [MENTION=40177]anabolism[/MENTION] I paid BA so about to call them now. it's a small change from one airport to another in the USA so hope it doesn't change it too much.

When you call to make the change, take this approach: "I'm thinking about changing my ticket [describe change here]. If I did that, would there be any additional charge? How much?" That's what I always do on any ticket. If you call and say, "Hi, I'd like to change my ticket to....", you could end up with an agent who, in his/her zeal to provide good customer service, makes the change before you understand the cost. Then the space you previously had may be unavailable. Overly cautious, yes; but I always prefer to avoid rather than solve problems.

I usually called (or emailed) the airlines that issued my ticket.
