Error codes

For UA operated flights see Using Miles to Upgrade on United
See UA's Star Alliance Upgrade Awards Page
Key points:
- Only a few fare classes (and expensive) are eligible -- depends on the carrier (see the UA page)
- Needs to be native flight numbers, codeshares are not eligible
- Generally no waitlisting but ANA allows waitlisting
- Most can be requested after ticketing (NH/ANA & ET cannot be requested earlier than 8 weeks to departure -- still true??) and must be done at least 24 hours prior to departure
- Max of 4 passengers can be upgraded
- Generally the available of award space is a good indicator of upgrade space (but not guaranteed) - typically requires (I) inventory
- Upgrade request can only be made electronically
- Upgrade requests are per segment
- It may increase your chance of success to request only one segment at a time on the upgrade page, even though it allows you to enter two (YMMV).
- For mileage requirements, see Interactive travel destinations awards chart

Need some advice, wasn't sure if I should put it here or not.
Looking for upgrade capabilities on Star Alliance flights, with a large stockpile of points on both Singapore and United. One person is Singapore Gold, and the other is United Premier Platinum, both looking to requalify on their airlines this year. Looking to buy premium economy or full fare economy from LAX to France early next month (can fly from New York or land somewhere else in Europe for cost/upgrade availability).
Is it best to book a singapore flight and upgrade iwth singapore points on both flights, and have one credited to united? Or book both on a United codeshare and upgrade with united points on both? Is there any routes I should look into for better chance of upgrade?

Save your SQ miles for award flights on SQ (in business or first class).

Which flight? I wouldn't necessarily count on getting a sane error message from the *A upgrade tool regardless of the reason. I see business award space on the 6:10 PM departure but not the 1:05 PM. The mileage upgrade awards clear into I inventory, the same as a business class award.
Thanks.
Is the 'I' inventory still the valid bucket to clear upgrade awards? Is there more to this than 'I' availability? I see award space available on the flight (could this be a phantom availability?) but the upgrade tool returns: 'Upgrade not available (Error code: 511)'
Thanks.
Thanks.

SFO-MUC
The upgrade finally went through successfully and I now have a certificate number confirming my upgrade. The itinerary in LH website reflects business class (I) upgrade but the United itinerary still shows Economy (G), hopefully the system will catch up and update to show the upgrade.
One weird thing I noticed on the Lufthansa site was an annotation stating that I need to check-in at the Economy counter (really doesn't matter in my case as my origin is AUS and I'm already in First class for the AUS-SFO leg) and that I don't get lounge access.
Do I gain access to the SFO Polaris lounge with this upgrade or will I have to settle for the United Club lounge?
Thank you!

I would fully expect access to the Polaris lounge at SFO as a passenger on an outbound LH J flight, regardless of how I got into J. I don't see anything in the rules to say otherwise.

I would ignore all that. It's now a business class ticket. LH IT is not the best.

An SFO departing LH J boarding pass will grant Polaris Lounge access. Enjoy!

One of the great things about int’l MileagePlus awards is that you have plenty of flexibility to stitch together itineraries based on one-way awards. The only real benefits to round-trip tickets are the Excursionist perk and reduced fees if you cancel or change your itinerary, but while they’re nice, flexibility is more useful.

Ah I doubt we will be using them for round trip tickets anyway. We make regular trips to Europe but part of that is domestic until we take the SAS flight for the international leg. We really just want to use the points for upgrades to international business class if possible. That's where I think it really pays off.
The best use of miles in any cabin is for saver awards.

In that case I’m not sure I follow. If you’re flying SK for the TATL leg, how would you expect to use UA miles to upgrade? Alas that’s not possible — and FYI, even on UA metal it’s rarely worthwhile to use miles to upgrade existing paid economy tickets, not least because of the extortionate copayments UA demands.
We normally take a UA metal from our local city to Chicago or Newark or something like that and then we catch a SAS flight to Europe. We use SAS because we often fly into Copenhagen. We then do the same thing back. Typically we simply buy all the tickets at one time through the SAS website because we also have Eurobonus points we accumulated. Last trip we had enough to upgrade to business class for the international portion of the flight home. I thought that was pretty awesome we started looking into mileage cards. Unfortunately we don't live in Europe so we couldn't get a SAS card so we did the next best thing and got the United (since they said you could apply points with other Star Alliance).

I'm pretty new to using these programs so please forgive me if I'm unfamiliar with all the terms and stuff like that. I did some research when I signed up for the UA program and their credit card. It clearly said that you could use UA points with their Star Alliance members. SAS is a member of the Star Alliance. What I assumed this meant was that I could buy an economy plus type ticket with SAS and then ask if there was an available seat upgrade I could apply my United points towards. Am I misunderstanding how those points could be used?

However, only the most expensive tickets can be upgraded; so-called full-fare premium economy* tickets. I don't know where you're starting from, but to give you an example -- from DEN to CPH, for random dates in July, the base fare (not including fuel surcharge, taxes, etc) for the cheapest upgradeable SAS fare is $2790 per person, round-trip. While that's still cheaper than the $4070 business class fare, it's not that much cheaper. (By comparison, the cheapest base fare on that route for those days is $990 in economy or $2090 in premium economy -- so you're paying a stiff penalty for the chance to upgrade).
International business class awards can be a great value, though -- while they take more miles, you only have to pay the taxes and fees -- usually around $100 or so for a TATL flight. I would focus on that rather than trying to use upgrades.
Note that you're allowed to combine Star Alliance partners in one trip. So, you can start from your city, fly United to EWR, and transfer to an SAS flight to CPH, all on one ticket.
* fare classes B, S, and Y. While Y and B are usually full-fare economy, SAS has decided that if you're paying full-fare economy prices, you deserve to sit in Premium Economy instead, so they've written those as premium economy fares.

Also, you cannot waitlist Star Alliance upgrades. They're either accepted or they're not (and you can try again later). Recent experience suggests that, at a minimum, the flight you want to take will need business class award space that partners (e.g., UA) can see, and even that might not be enough. So, if you decide to go this route, you should understand that there's a chance you'll end up sitting in PE.
