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

If it is a true LH flight number (AC usually lists both) such that it only shows LH567 ... then yes ... LH only looks at the booking class they see and not at the fare basis. Plus points or miles should work.

Success J-->F on LH
Had a relatively pleasant experience using UA miles to go from J to F on LH for a flight in 2 days. Was booked in J (D class fare) XXX-FRA-LAX. XXX-FRA is a 2 class EuroJ flight. Both segments booked as UA codeshare on 016 ticket stock. Called in and agent understood about switching to the native LH flight number, but it requires the same booking code to be available which she wasn't seeing. She got a supervisor involved (with no prompting) and supervisor reached out to LH and they agreed to switch me onto the LH flight number. I just had to stay out of the PNR for a while and I got an email confirming the change. Then submitted the request and was pleasantly surprised when it cleared immediately and only cost 25k miles! Looking at the old chart it was showing 40k miles to go from J to F.
I was actually so confused I thought it was messed up so I backed out the first time, tried selecting my current class as Economy just to see and got an error that the class didn't match the ticketed class. So then I tried again selecting Biz as current cabin and got an error that no upgrade was available! But I figured my previous request had just locked it for a bit, so I waited about 15 minutes, did it again, saw the 25k and never looked back. Got an email confirmation shortly after and selected the last free seat in the 748 F cabin. Now I just have to decide on the FCL or FCT

I'm consistently getting this error trying to UG a SAS flight. I never got the same name error or any other error, and it's a simple ticket with one passenger. UA has no idea what to do and told me I should call SAS and ask them. I'm assuming they'll have absolutely no idea what I'm talking about and to call United back, but does anyone have any ideas what's going on?

I think it had to do with with voiding the ticket and PNR and starting over from scratch

This has been going on for months - the UA system is broken, and no one is willing or interested in fixing it, regardless of how many complaints I filed or who I involved in the discussion including escalating through my sales rep. I think I was able to defeat this error somehow, but I can't remember how - go check the EVA upgrade/*A thread here in the United forum where I posted details of my last adventure dealing with this.

I did see that post, but voiding the ticket is not an option unless I dont understand what that means. I dont really care whether the self serve web tool works, I care that theres some way for agents to do it when the tool is broken. But like you said, so far no one cares.
Basically you would need to cancel/refund the ticket and start over with a new reservation and new ticket. How did you issue the ticket? This is why using an brick and mortar agent is almost essential for making this process work smoothly, although I've honestly lost too much hair dealing with it.

The self serve tool is the only option - United has not provided any tools for agent to search for, or process *A upgrades. This is pretty consistent with most members, they seem to offer up *A upgrades very grudgingly and have no interest in making it easier for consumers to grab these.

I would just keep calling UA over and over and complaining until you get someone willing to escalate. Its not a great use of your time but the only option - however dont let them transfer you to the web help desk, these folks are overseas and across quite a few hair pulling conversations, they actually do not speak English competently, have extreme difficulty comprehending the actual problem, generally work off a script and will not be able to help.
