I have a trip recently booked on through our corporate travel agent, which includes LH segments, AC segments, and an AC-codeshare/LH-operated segment. The ticket is 014-plated, and all segments show as T-fares on the invoice and on both AC and LH web sites. I have both AC and LH PNRs.

How can I determine fare class of the codeshare segment? Even LH's web site shows this flight as an AC flight, not recognizing that they actually are operating it.

Thanks.

EDIT: Removed link since it is broken for the new beta site... sigh

EDIT2 (Debugged): Accumulation info is here: https://beta.aircanada.com/content/d...milage_en.html but it tries to be too 'smart' and defaults to A3. LH info here: https://beta.aircanada.com/content/d...og-box/lh.json

It says T will accumulate 50%, which is the reason I assume you've asked?

Sort of. What I'm trying to confirm is whether a the T-fare on an AC-marketed/LH-operated flight stays as a T-fare on LH, or changes to something else (like, heaven forbid, K). Since it is the operating carrier's fare class, not the marketing carrier's, I need this to know the UA MileagePlus accumulation.

Well, looking at the Aeroplan accumulation page, and knowing that it will earn 50% based on my previous post, we can see that it will be one of these codes:

• W, S, T, or L for international flights
• Y, B, M, U, H, Q, V, W, S, T, or L for European flights

Looking at the UA MP accrual page for LH, we can surmise you'll earn somewhere between 50%-100%. Not exactly useful.

I'd just phone LH and ask .

Actually that is untrue, we don't know what a T fare booking will translate into on LH and it could easily be a K fare and hence zero accumulation.

My PY flights that connect onto SQ go into a zero accumulation bucket on SQ. Net result is I don't fly SQ connections anymore. Once I hit my AQD I fly other *A carriers now.

If AC/SQ cleared up their fare booking mappings so we could accumulate miles clearly then they would both get more business. Also, those SQ flights aren't full, they could definitely use more customers in Y... which reminds me, my PY ticket doesn't map to a PY seat on connecting Airlines that are Codeshares.

Are you sure? The page I linked in my original reply says it is a 50% earning for a T fare code on an AC codeshare on LH metal. So either that page is a straight up lie, or you are mistaken. Thus, if the page in my furst post is accurate, the T codeshare fare code must book into one of the fare buckets I listed in the 2nd post.

This is probably expected. See here: https://beta.aircanada.com/content/d...og-box/sq.json

Looks like not too many AC codeshare fare codes on SQ metal earn anything.

I think what quantumofforce means is that AC is selling it as T fare but that is not necessarily a T in the LH system. AC may actually be mapping their T onto a K fare from LH. The marketed fare does not matter, just the operating carrier's fare code.
It can be extraordinarily hard to pin either airline down in advance about what the fare code mapping is.

I know this is what he said. Did you read the links in my original reply? They list the earnings on the AC fare code. The fair code that is marketed by AC, on their codeshare. Not the LH fare code. We know the AC fare code is T, and that it will earn 50% because of this. This is my point. We don't need to know what fare it maps to to know it earns 50%, based on, again, the two links in my original post. That is, unless you think Air Canada will put plain old pure lies on its website.

Yes they will lie. They will sell codeshares under one class and then the operating airline will show a different class. I have had this happen several times this year.

My understanding is that the fare code AC sells it under doesn't matter. It's the fare code that LH assigns it to. The tables you link to show earnings by AC fare class for flights operated by AC and by LH fare class for flights operated by LH. It doesn't show how to figure out what LH fare class I'll get on an AC T fare operated by LH.

In a certain sense, it doesn't really matter, since the ticket is purchased and I'll get what I get. But I'm still interested to know if there is a way to figure it out.

If you find a mapping, please do share! I would love to know.

Incorrect. The page shows AC codeshare fare codes for flights operated by LH.

Either FT's English comprehension is rock bottom, or Canadian English has significantly changed since I've moved to the UK, and I wasn't informed.

Therefore, I am going to explain with pictures and lists. I would greatly appreciate it if anyone who replies could point out exactly where my logic or interpretation of the English language is failing here. (I'm serious.)

So. Let's load the first link, in my first post, with LH selected as the airline. We get this:



Let's now look at the relevant information, bit by bit:



Indeed this page is for information regarding the accumulation of miles to one's Aeroplan account, on Lufthansa metal flights. Let's continue.



Noting the underlined part, we see that this chart is for AC-marketed codeshare fare codes, on LH metal, *not* LH fare codes.



The chart itself. It shows the AC marketed fare codes, and what they'll earn if you credit them to an Aeroplan account. T is listed here as earning 50%, as I stated multiple times.



This image is just to drive home that it is indeed the codeshare fare codes listed, which people seem to have trouble believing/comprehending (?).

Continuing.

OK, so we now know that an AC-marketed codeshare T face code will map to some unknown fare code on LH metal that will earn 50% mileage on Aeroplan, based on the above page and images. We know it must map to something that will earn 50% mileage.

Looking at the mileage accumulation page for LH fare codes on aeroplan.com we see:



We know it'll earn 50%, ergo the T codeshare code must map to one of the codes listed as 50% earning on LH-marketed LH flights, i.e.: Y, B, M, U, H, Q, V, W, S, T, or L. Great. We now have at least a group of LH fare codes it could possibly map to.

Next, let's look at UA MP's earning for LH-marketed LH flights:



We can see all of the possible LH-marketed LH fare codes will earn at least 50%. So, the strongest conclusion we can make is that silver_halide's flight will earn at least 50%, but maybe more. That's better than it possibly earning 0%, no?

I've tired to be exceptionally clear here, and I would appreciate it if anyone could point out if I've gone wrong somewhere, or where there is a fault in my logic. If I see replies akin to "no, you're wrong" without any evidence, I am going to assume you haven't read my post fully, or at all.

Cool. How did you find this?

So the first link gives Aegean and the second some JSON code. How do I get to the LH page that looks like the Aegean one?

Additionally, if I go to https://beta.aircanada.com/content/d...og-box/nh.json (following the same pattern) I notice that the information does not appear to be consistent with what I found for accumulation on ANA (see my other thread) specifically where I had an AC fare bucket of H on a codeshare but got only 50% miles instead of the 70% that the JSON listing would appear to sugegst.

It's a popup when booking codeshares, IIRC. I loaded the URL I always used to use, and it redirected me to that (crappy/broken) page on the beta website.

Looking at its source, it loads aeroplanmilage.js, which loads info like so:

Nice of AC to not minify any of their JS... You'll note it defaults to Aegean.

I forced it to load lh.json rather than the default a3.json by mucking around with Chrome's dev tools. I'm not frontend web guy, and am not familiar with Angular, so I'm not exactly sure where it tries to read the IATA code from (urlVarService.getVars()). I'm sure someone else on this forum does though.

That's actually quite concerning... It means AC is showing users incorrect information .

+1
Bait and switch. Bought J but codeshare portion (non AC metal) was Y. Neither airline could properly explain why codeshare wasn't J. And, it was not a *A partner so no pts.
