The general question is when to believe L/D/A availability via EF. For those who have an ex-SEZ ticket in hand and plan to revise it after the 1st flown segment, what is the POS, SEZ or where the ticket is reissued? skunker stated that there was D available, yet had to enter the entire itinerary to reissue which caused D class to show 0.

I'm confused. You were trying to book a RTW that had both LAX-BOS and LAX-JFK in it?

The point of sale is usually based on the agency booking your ticket, not the starting point. So, if booking an ex-JNB RTW by phoning the AA RTW desk, the point of sale is the US even though the ticket starts in JNB. If you booked an ex-SEZ RTW using an agent, then the point of sale is wherever that agen or the agent's agency is based.

It's not supposed to be possible to book a QF codeshare unless connecting to or from a QF flight (e.g., a QF flight arriving into JFK, DFW, LAX, or SFO within 24 hour of the desired codeshare). However, some agents will book and ticket codeshares that don't meet this.

Two different ones; and now that chatting with you has occasioned me to look, there are actually three in my current itineraries. I had a LAX-BOS segment on the DONE4 I'm in the middle of right now. I have a LAX-JFK segment on the AONE5 I'm starting in mid-February; and I have a LAX-JFK segment on the AONE4 I'm starting in April.

Actually, I've done multiple transcons twice before. Once was a LAX-RDU-LAX same day turn when AA first started the service before RDU was added to the list of east coast cities in the rules, and later the same thing with LAX-MBJ-LAX, another same day turn.

So, if I may ask, what were the specific sets of flights where EF showed D available yet an agent saw D0 when trying to book into an RTW?

Because EF pulls from the presumably same GDS data as an agent booking an RTW, I'm trying to understand where people have experienced the discrepancy. We've all seen many cases of married segment logic where D is not available on a set of flights booked as a connection, or where D is available from one point of sale but not for another, but reportedly neither is the case here.

Here is one situation that I encountered.

I tried to add SCL IPC to my DONEx via CX HKG. no D space (via HKG POS EF)..
however there is D space when US POS is set on EF. I called CX north America and able to get the space.

(I asked the CX North America and they told me the use the availability from North America in their North American system).

I believe [MENTION=794258]Leaping_Deere[/MENTION] was talking about nesting another ticket within the RTW and wanted to keep everything in one PNR. If the other ticket is on AA flights, BA would not be able to issue it on its plate in a BA-created PNR unless one is using the oneworld Visit North America fare.

I'm referring to the idea (perhaps I read it wrong) that you wanted to add extra segments that will be on a separate ticket, but you wanted everything in one PNR. If those extra flights are AA flights, BA might not be able to price them or will have to price them on a much higher fare. Of course, it all depends on the fare you want.

Here are the details, slightly different from what I said, but same principle. That will teach me to try to do things from memory!!

1. 20 February 2019, AA 274 LAX-JFK 1200-2025 STILL shows A6. Agent was unable to sell it on the AA number, but got it for me as QF 3101.

2. 9 April 2019, AA 256 LAX-ORD 0920-1507 NOW shows D0, but was D7 when I was booking it. Agent was unable to sell it on the AA number, but got it for me as BA 4372.

3. 9 April 2019, AA 2364 ORD-LAX 1710-1931 NOW shows D1, but was D7 when I was booking it. Agent was unable to sell it on the AA number, but got it for me as BA 4349.

4. 10 April 2019, AA 167 LAX-BOS 0830-1716 NOW shows D0, but was D7 when I was booking it. Agent was unable to sell it on the AA number, but got it for me as BA 2500.

In each of these four cases, did you check EF using the same point-of-sale as the agent booking your RTW? In each of the four cases, was there 24 hours or more before and after the flight in question?

I'm just trying to understand what are the reported instances where EF's data is different from that of the agent booking the RTW. Different points of sale (as with pbd456's case) are already something we know about here. Married-segment logic is also well-known here.

Until you asked this question and I looked, I hadn't realized that one could specify point of sale in the EF availability display. So the answer is no; it was at the default, which is U.S. Agent was in Australia. Just checked again, changed it to Australia, and AA 274 LAX-JFK on 20 February 2019 still shows A6.

Thanks for all the kind replies (from everyone), will definitely keep it in mind if we get to the point of trying to schedule one of these!

BA can and do issue fully AA itineraries on 125 stock. (I have plenty of personal experience.)

It’s in line with the policy on the usage of 125 stock, which, separately from tickets containing BA flights, also allows it to be used on itineraries containing only AA, AY, EI, IB, JL, and/or VY flights.

Most (but not all) AA fares can be issued by BA. The "instant upgrade" domestic fares usually must be issued on 001 AA stock.

However, many BA staff do not know this or do not want to do it.

Yes, for this itinerary it is possible to issue on BA plate. I should have said "might not be able" (which is what I first said) instead of "would not be able" (my subsequent post).

Yet when your agent tries to book it into an RTW, it shows A0? And this is with 24 hours or more before and after this one flight?
