2019-Mar-15 New Version of the Rule Sheet
 

I usually use diffchecker to find the changes, but for some reason this time diffchecker flags pretty much the whole document as being different (which it isn't)

So I scanned through the new version and the only change I've spotted is the removal of the highlighted words below:

Are things much the same coming up for June 2019, pandaperth?

I dunno
I don't have any insider information - I merely periodically check the on-line rule sheet for changes
However, it appears that @anabolism does have insider information - see this post

ETA
and as of this morning (June 6th) the rule sheet is unchanged
(changes usually occur around the start of the month)

Is it really D class
 

I have tried several times lately to book RTW tickets and both oneworld.com and expertflyer have shown availability in D class but BA have not agreed. I guess there is a suitably complicated reason for this but BA aren't forthcoming. Can anyone explain or point me to a post that will?

* Married segments
* Availability differs at different points of sale
* Agent confusion

Can you be more specific about your itinerary?

Don't forget possible codeshare issues.

Thanks for the comments. So specially this flight. Wanting to fly QF JFK to MEL via LAX and they say this segment is not available in D when Expertflyer says D class is available. Now, thanks to your help I think I see why. I can't make POS Belgium in Experflyer so I used France and it shows as D0 but US POS shows as D9. I guess that then is the issue.

It may also be a "married segment" issue in that QF apparently requires a QF flight transPacific in order to book QF12.

Just wandering

Exactly. QF 11 and 12 cannot be booked other than as part of a TPAC itinerary.

So I already had a TPAC booked (MEL) from LAX and was connecting to that from SJC. But I needed to change the connection to JFK instead. That seems to me to be a correct booking (i.e. JFK>LAX>MEL....). No?

What does availability show when you search JFK-(LAX)-MEL? When I search JFK-(LAX)-MEL on 27SEP with USA POS or France POS, I see D0 for QF12 connecting to QF94 or QF96.

This is what I am seeing (D7 for JFK>LAX). The D0 for LAX>MEL is correct but I already had that leg locked so it wasn't an issue.

IMHO, THAT IS THE ISSUE.
For example,
A-xB-C (no availability married segments)
You book D-xB-C (availability, so you get D-B and B-C segments confirmed)
Now, you want to change segment D-B to A-B. You have availability of A-B, but not for A-xB-C.
This scenario is evasion of married segments booking control of airline.
Some airline (e.g ANA) charge penalty to travel agents which do this type of evasion.

Thanks, Wasabi Tofu. I think I understand that. And if I understand correctly, it makes sense.

So here is another example. I am trying to book BRU>PER via DOH on Qatar on September 13. Expert flyer says yes to D class:

But the OW website says no:

The full itinerary after PER is, surface to SYD then SYD>MEL>LAX>SEA>ORD>BOS>EWR>BRU. Maybe it is one of those screwing up the marriage but where the hell do I start to figure that out?
