I really don't know to be honest. I'd speculate that it's maybe a Carina thing. I once booked a client a 30+ sector business trip across multiple airlines and one-way tickets. This was all done in a single Sabre PNR which meant that each airline also had a single PNR of their own (some with multiple tickets for 1 pax in the same PNR if they were operating multiple sectors). The most important thing for the client was schedule and so *A/OW/ST wasn't important; resulting in a real mix of carriers such as NZ, BA, SQ, DL, UA, AA, VS, CZ, MH etc. I seem to recall on pretty much all airlines' manage booking sites most, if not all sectors of the itinerary showed. Of course, there was one airline exception to that......

My biggest issue from a broker perspective is being able to see definitively what a client's tier status is. The great thing with OW is that when I enter a FF# into a Sabre PNR, it tells me what their status is. Usually it is the airline's own status level which I then match to the equivalent OW level. Some tell me both. I obviously don't deal with FF members of all OW airlines with me being located in NZ, but from those that I have dealt with it seems to be alliance-wide (off the top of my head I've gotten tier info from QF/QR/CX/BA/AA/MH/IB). For QF, I also get a specific message if they are Chairman's Lounge (which also comes up if I do an EK booking for a CL member).

*A don't do this based on the FF members I've dealt booked travel for, with one exception. When I enter the FF# for *A, I only get told if it's valid and accepted or incorrect - nothing about tier status. The one exception with this was UA. One of my clients here in NZ used to be GS and UA would place an OSI in the PNR telling me so. Unfortunately I no longer book for the client as he's no longer based in NZ so I don't know if he's still GS or if UA still send this message. I don't get anything in the PNR for any of my EP1 clients.

No worries Thai-Kiwi ! Info sectors are done automatically at the time of PNR creation (but they can be manually adjusted as well). I would be interested to know what is incorrect about that segment then I could give an educated guess as to why it's there. As an uneducated guess, I would say that the TG agent created a booking with that flight (either by mistake or you wanted it but later changed to a different one) and ended the booking, which then created 2 PNRs - 1x TG & 1x NZ. As this is the time of PNR creation, the flight was transmitted to the NZ PNR as an info sector. For whatever reason you've changed that flight to something else or the TG agent realised it was wrong and corrected it. However, the correct flight details haven't been sent through to NZ nor have the incorrect ones been removed (this is very common...).

The issue I think - and it's not unique to TG or NZ, but most airlines - is that automatic 'cleaning' of info sectors can be very temperamental. I know with NZ their service control (part of the reason the flight goes to airport control at T-48) do go through and try to reconcile/validate PNR sectors (booked and info), e-ticket data, and DCS interline systems to make sure everything matches. NZ call centre staff can do this too at any time and they have two methods to do so in their internal res system QikSilver. The first method is pretty much a "click one button" job which reads the coupons on the e-ticket and then automatically adds in those info sectors that aren't there. This includes all OAL sectors, not just the ones to/from an NZ flight, which potentially adds the whole lot to your app. The agent then just has to delete any of the old ones from the PNR. The only problem is that most of the time the process either fails entirely or doesn't add them all. Alternatively, a CC agent can do this process manually sector-by-sector. Despite it being relatively simple for someone with a bit of experience, it's something few know how to do - it's a bit more complicated with multiple steps. Also AFAIK, it's a process not actively taught during training - like many system manipulation methods it's just something picked up on the job.
