This is the archive thread, the active thread is Lufthansa GPUs Go Electronic (How to use, will it clear?, issues w/flight credit,...)

For general information on upgrading ANA or Lufthansa flights with a GPU, see Upgrading Flights Operated by ANA or Lufthansa. You actually request the upgrade through the online form, here: Request a GPU for a Select Partner Airline.

Per United web support, you only need to fill in the required* info.

**The LH flight you are upgrading must be an LH flight, not a UA codeshare flight. If you have a UA codeshare flight, you can call websupport and they will (put you on hold and] change your itinerary to one with an LH flight#.

Note that UA websupport might give you a new ticket # when you do the above, but if the original ticket # was 016 UA stock, it will remain so, and thus you will still be earning RDMs at the UA rate (11x for a 1K), not the *A rate. In case of a $6000 biz fare for LAX-FRA that you are trying to upgrade to F for example, as a 1K you would earn 66,000 UA RDM if booked as a UA flight. And even though after booking you get them to change the UA flight # from a UA codeshare flight to an LH flight, the 016 ticket stock sticks, and you earn 66,000 RDMs.

(FYI, had the ticket stock been an LH stock, the RDM's earned would be 5790 miles x 150% = 8685 RDMs. Big difference)

Note that sometimes the online upgrading does not work, and you may get an error message to call an 877 number, which is now defunct but still resides on .bomb...Ignore it and just call web support. They might put you on hold while they call LH but they will get the job done.

Eligible Economy Fares to Apply a GPU

Upgradeable to business fares include U/H/Q the lowest eligible economy fares. G&E the two top premium economy fares and Y/B/M the most expensive economy fares. (http://www.flyertalk.com/forum/24219165-post205.html) For C->F upgrade, J, D, C fares are eligible, Z and P fares are not. From April to September 2018 it was possible to confirm and waitlist P ,Z-class LH flights with a GPU. Confirming and waitlisting is no now longer possible, but previously waitlisted segments will continue to clear as/if available.

Checking for Upgrade Availability

Upgrades to E, C and F come from the N, I and O fare bucket, but its a subset, which theoretically is not the same as the award subset. If awards are available it is a strong indication the upgrade is available too. (http://www.flyertalk.com/forum/24861289-post342.html)

In case of upgrade clearing but eticket refresh problems:

Checking for availability prior to calling
Use ANA or even united.com to see availability.

To check if C/F upgrades may open up, ask in this thread: Determining LH Y/C/F loads? [the help me guesstimate loads thread]

Regarding ticket stock, Oliver reports:
Each LH flight segment requires a separate GPU
A single GPU can be used to only upgrade a single LH flight segment, And that GPU cannot be extended to include another LH flight segment or another UA flight segment.


Problems getting mileage credit for upgraded LH segments

Numerous reports of denial of mileage credits (RDMs, PQMs, PQSs, PQDs) for upgraded tickets. This issue is probably due to LH uses the same fare bucket for mileage awards and upgrades. It seems patience, persistence, and documentation of the originally paid fare are needed to get credit.

You probably won't get credit by simply submitting the online form or asking a CSR to do so for you. A CSR needs to submit a System Issue Form, together with the mileage request, explaining that you flew in I class, but you paid for a mileage-earning booking class.

T-10

While the original system did not allow the upgrade waitlist to carry on past t-10 hours, the have been multiple reports that this is no longer the case. If not cleared in advance - the upgrade wait-list will last all the way until the door closing. UA has not updated the text on the LH GPU upgrades to reflect this change.
