How many Aeroplan miles did that cost? I've never done an Aeroplan upgrade before however I have a lot of miles to use up. This could be a good option for me.

Just did it now, thanks to flyCsG's tip! 25,000 oneway from B fare YVR-TPE. Debating adding the 90 minute connection for an additional 10,000. Odds are I'll just fall asleep anyhow, so not as convinced on the second value.

What does this mean? Married Segment Control, by definition, is when they tie the segments together for faring purposes. BR's upgrade, by rule, is per segment.

Forgot to check back on the thread. Yes, I asked specifically for SAUA.

25K each way, so 50K total. Worth nothing my itinerary is actually YYZ-TPE-KUL-TPE-YYZ. The segments with KUL were not upgraded (no availability).

Does anyone know if there is a glitch currently in SAUA availability on BR? I'm trying to apply an SAUA to a BR flight showing availability on EF, but both Aeroplan and Asiana websites are saying no upgrade availability. I've actually changed the date of the flight between two days showing availability on EF, but neither day would show availability when I actually try to redeem the upgrade.

Yes, EF is reporting I class as "Yes". I also looked on KVS, which gives C+ for the same availability. I will try calling Aeroplan to see if they can manually process it.

They will have to probably call BR and inquire further about the availability.

Upgrade go to Z class. People use I class as a gauge of Z class availability since Z class won't show up on EF.

Interesting... Some people have said SAUA availability is I and some have said Z, within this thread and others.
Aeroplan agent couldn't do anything to check availability. EVA agent said they can't see SAUA availablility and said Z was not available. Still not bookable via Aeroplan or Asiana. EF and KVS show I availability and CS+ respectively; in these circumstances, I could have easily upgraded via Aeroplan already. Not sure what's going on.

My understanding (from both reading FT and IME) is SAUA needs Z class availability (need to call into BR to inquire for Z class) - not sure why others are saying I class.

What people are reporting seem to be "need availability in Z but booked into I when it is all done".

Still booked into Z as that is shown on confirmation.

Mile upgrade from Y definitely books into Z and award definitely books into I class. Just made Aeroplan redemptions from last month for both.

IME (using UA miles), SAUA has always booked into Z.

Because that's where the *A upgrade books on most other carriers. An understandable mistake.

It makes sense that I class is "subset" of Z .

You clearly have reading reading comprehension problems so I see no point in responding to your misguided commentary.

Except to note that you're the one who got this wrong above:

:rolleyes:

That was definitely my experience as well. Or at least I=0 for sure, had a friend check EF but we didn't know to look at Z. Rolled the dice on upgrade anyhow (where's the harm?) and it cleared instantly on a one way B fare.

This has been exactly my experience and rationale as well. I only do SAUAs on one-way B fare when awards (I fares) are not available.

I can't even find Z awards on EF.

Z is a separate class that rev. mgmt. updates once a day based on booking trends. However, those using SAUA have less priority then BR's own FF. Rev. mgmt. will clear the BR FF first before opening up more to SAUA. What is already out there is fair game.

According to the information that we have, *A Upgrades on BR flights require I Class (AKA CS for KVS Tool Users), but are then ticketed in Z Class, which is causing a lot of confusion.

These details are also reflected in the BR section of the KVS Tool User Guide.

As stated, every time I have used SAUA there has not been I class availability.

Thanks everyone for your comments. Here is my hypothesis:
I've been trying to upgrade an SFO-TPE leg in the coming week using Aeroplan miles. There are three flights on the day: 17, 27, 7 departing at 0045, 0100, 1300 respectively. In the past two days, I've called EVA to change the flight from 17, to 27, to 7, trying to do SAUA at Aeroplan after each change. I also asked the EVA agent about availability of classes I and Z. Each flight had a different combination of factors, and it seemed enlightening to me:

BR 17, I not available, Z not available, EF says no, KVS says no, SAUA not possible

BR 27, I available, Z not available, EF says yes, KVS says yes, SAUA not possible

BR 7, I available, Z available, EF says yes, KVS says yes, SAUA possible

The circumstance of this particular day's BR 27 has never happened to me until this week. In the numerous times I've done SAUA on EVA flights from/to SFO, TPE, and CDG, if EF/KVS said yes, then SAUA was possible. Just based on this, it seems that both I and Z availability is required for SAUA. However, EF and KVS only show availability based on I. Now, I feel like I'll have to call EVA every time to confirm that Z is also available, before I try SAUA.

Hopefully others can use this and other comments in this thread as reference for their own SAUA experiences.

X2.
That is why I go the upgrade route instead of mile redemption.

Just rolled the dice and ended up getting an SAUA:

September departure, October return, Aeroplan upgrade. YYZ-TPE-YYZ, both flights were I=0 and Z>1 (confirmed by BR agent).

So we're still no closer to figuring out the magic sauce.

I do not know why you think it is magic. There is no magic. It is clear to me from reading this thread that the condition necessary for SAUA on BR is Z>0 which you had. In order to confirm Z availability you need to call BR. Neither KVS nor EF shows Z availability on BR so you need to call BR to confirm it.

More data points are always helpful when there is stubborn resistance to existing data points.

Not true. Tickets from I buckets clear into I; they do not clear into Z. Attached is proof; note the I denoted at the bottom right.

I have had many successes using a SAUA when there is no "I" class available. I don't use KVS or CS to check though. I just call EVA directly and ask them if they have Z-class upgradeable seats available on my flights of interest.

There have been times when I call and they ask if I'm using United miles to upgrade and if I replied yes, then they told me there were no I-class seats available. I continue to tell them I just want to know if there are Z-class seats available. When Z-class seats were available and I-class weren't, I would still be successful in upgrading using a SAUA.

My friends and I recently did this a few months ago. 3 of us all got upgraded on SFO-TPE and TPE-SFO when Z-class seats were available, but I-class weren't. Again, this is Z-class vs I-class per what EVA reps tell me when I call, not via any of the tools.

DP for anyone interested, since I've been following this thread for a while and nothing really made sense, the last post relevant to me was in March and it was pretty annoying to filter out the misinformation. Btw, thanks to Gengar it was your confident post that made me pull the trigger and you were right all along.
Booked: Today, July 3
Travel: January 2019/February 2019
SAUA program: Aeroplan, 25k points per way
BR 9 to upgrade to BUSINESS in this itinerary: YEG - [YVR - TPE] - SGN
Z = 8, I = 0, but agent confirmed Z is what mattered. ExpertFlyer only shows I, you have to call in to get Z availability
Hold time at 13:00 UTC-5: 30 mins to North American reservations number for Z availability check
75 seconds between clicking buy button on evaair.com and upgrade confirmed on Aeroplan site (to be fair I was probably too quick that if the upgrade declined I'd be freaking out)

Original fare booking classes: YEG -> YVR in S, YVR -> TPE -> SGN in B, SGN -> TPE -> YVR in Q, YVR -> YEG in K. YEG segments on AC.

I have a B-fare flight on EVA which was upgraded to Z. If I change my ticket to fly with another airline, I guess I will drop back in economy (B) but will I get my miles back?

If you did it with Aeroplan, I think this is what happens from their T&C:

I was trying to book a B class ticket on eva to upgrade to business, as I usually have done. I have not been able to see B class fares, only M fares from TPE to LAX/SFO? Has any one else encountered the same problem?
