Changing dates (thought it might not be a daily flight) did not solve the problem.

What dates did you try? What class are you looking for?

Looking in expertflyer, both business class and economy class (booking codes D and L) availability is patchy on LA600 - some days have zero availability in one or other.
I just did a dummy itinerary in the tool (SCL-LAX-HKG-LHR-MAD-SCL) - found LA600 available for a date that showed L availability in expertflyer

I am looking for D, around mid Mar. Simply nothing available! Even looked on aa com. I don't use EF.

This is confusing

In the tool, I am using a simple itinerary (SYD-LHR-MAD-SCL-LAX-SYD) and for SCL-LAX on LA600 I'm seeing D availability on 10 of the 14 days in the mid-March period (9-22 March)
- I presume this doesn't match what you're seeing

In expertflyer I'm seeing D availability on 8 of the 14 days

But 4 of the days that expertflyer says have zero D availability, the tool shows availability
And for 2 of the days that expertflyer says have availability, the tools shows no availability

So something is wrong somewhere

(Note: I'm looking for only one seat)

The inconsistency between various tools ( aa com; oneworld timetables; ow rtw booking tool, not in position to comment about EF) is a real disappointment, if not a source of frustration!
Thanks for checking

EF is the only on-line source I use. When I find availability, I call the rtw desk for my booking. I can't recall any occasion on which EF and rtw didn't agree about D or A availability on any airline. W is another matter. EF often shows W available on LA and rtw says no availability.

With QR joining the booking tool now seems to include the QR routes during the city selection screen, but when you go to pick flights no QR flights are displayed.

I sent a ticket into oneworld so hopefully it gets fixed soon.

QR flights now appear to be loaded and selectable in the booking tool, rather than just the online timetable. However, there is this caveat on the oneworld page:

"NOTE: on 1 November 2013, Qatar Airways flights will not be available as the first segment of your itinerary when booking your oneworld Explorer itinerary through our online booking tool. To originate your oneworld Explorer itinerary on Qatar Airways please contact your Travel Agent or Qatar Airways http://www.qatarairways.com/contactus."

On a separate (or possibly related) note, I've got an itinerary in the tool that goes SSH-AMM-DME-xDOH-IAH . . . HKG-JED but the tool says it's incomplete, wanting to return me to SSH. Is this a bug or have I done something wrong?

I played around with the cities and my itinerary originating in SSH and ending in JED is now bookable.

Watch out that the tool doesn't price it for a Saudi origination rather than Egyptian. This has been a recurring problem when using the tool for an itinerary ending in a different Middle East country than the origin.

Thanks for that. Good to know. I've priced it up and it comes to a little under USD6300 which I'm happy with.

Anyone have any idea if this is going to be on-going or just an initial issue while QR get used to the RTW fares? Real pain as from South Africa they are the only option for a first leg to Europe and any itineraries travelling in a westerly direction.

Long time reader, first post.

Logged onto the xONEx tool tonight and an itinerary I had saved (and which was pricing okay with dummy dates) is now presenting an error and doesn't seem to let me resolve it.

The error is:
"2621: One of the visits to Europe must be a transfer without stopover (less than 24 hours) between Africa and the previous/next continent. Additionally travel may not include Mauritius/South Africa."

The itinerary which up until today was working alright is:

JNB-LHR-MCT-LHR|LHR-LAX-DFW-SEA|SEA-DFW-JFK|JFK-HKG-BOM-HKG-DEL|DEL-NRT-SYD|SYD-LHR-NBO with vertical lines representing stopovers.

I've read the rule sheet available on the Oneworld site and can't understand what has changed in the past 48 hours, can someone help?

Yes. The rules have just changed. The copy of the rules on the Oneworld web site has not yet been updated (and in fact the web site is now showing an old version of the rules - from 1 July 2013)

The changes are being discussed in the Changes to the xONEx Rule Sheet thread - see from post #66 onwards.
Sadly, your itinerary is no longer valid

What? Has BA stopped flying to Sth Africa?
