Weird stuff. LH called me to say they are seeing the upgraded leg in F (as it should be) and also in business class!!! They suggested I call United to fix this.

The flights look good on UA, but I can now see the upgraded leg listed twice on LH as the agent said. They also have different receipt numbers.

Should I call United or just ignore this? Based on past experience in this thread, looks like I should not have United do anything with the reservation ...

That's not good. Someone messed with this then ... best is to not call and to leave this alone, but here you are with 2 segments on the LH end. Why did LH call you? You should have left this alone in the first place.

I would try and get this resolved, because this can lead to problems including losing the upgrade. Start with LH and call the F hotline - see if they can adjust it on their end. Did UA re-issue the ticket? Something happened here.

This happened to me once and LH automatically canceled the upgraded segment. In my case, I had UA drop the old segment (after thankfully reapplying and reclearing since there was still space).

It's been a few years for me, but despite the advice here being "never call", I would always check LH seatmap to make sure my old seat was released to avoid issues with duplicate confirmed segments.

I didn't call LH, they called me. I didn't call United either, based on the advice here

LH F hotline is closed now, will call tomorrow

I don't have a seat in business class, but the segment is listed twice (business and first), shows F seat assignment.

you called United, at least you claim you did (https://www.flyertalk.com/forum/36661803-post110.html). The F hotline is your best bet to get that extra C segment removed.

Sorry if that wasn't clear.

I called UA before posting here. The agent kept insisting the segment was waitlisted, even though it showed confirmed on LH. So I gave up.

I then posted here asking for suggestions and was told not to try and fix this, so I haven't called them since.

Thanks for the F hotline tip. They removed the extra segment in C, was told "United didn't sync correctly after the upgrade was processed".

Looks this happens often and LH has to clean up afterwards from what I heard on the call.

Never a dull moment.

The fault on this one is hard to assign. LH makes a change (sticker upgrade) on a UA ticket and UA determines the ticket is out-of-sync / different than issued. The sticker upgrade is a workaround but the out-of-sync does not recognize -- it is intent for other issues (seat change, time change, flight number change, ....) but cabin change isn't something normally expected. UA can handle UA upgrades UA operated flights. The carriers invented a special system of using miles (and later GPU/PlusPoints upgrades) on other carriers -- so both airlines are aware of what is happening. But cash sticker upgrades are not so supported. It is a practice asking for trouble.

I have an upcoming open-jaw ticket for ORD-LHR (UA), GDN-FRA-ORD (LH). It took me three UA agents and two support desks to be able to price this out according to fare bases found on ITA Matrix using LH flight numbers.

Originally, when I booked this ticket, LH.com showed me upgrade capabilities for FRA-ORD (as it should). Then, when I applied a waitlisted upgrade request to ORD-LHR (very likely to clear on a high-J 763), the option to upgrade FRA-ORD with cash disappeared. I am very interested in preserving the option to upgrade this return TATL segment since this is on a 748 with a high percentage of J seats that usually go unsold.

Will this upgrade option reappear on LH.com once the UA segment is either confirmed or flown without the upgrade?

maybe, maybe not. The WL is likely the culprit for not seeing the return UG offer anymore. Have you tried cancelling the UA upgrade request and see, if that brings back the offer on the LH end? Maybe buy that UG first and then WL on UA?

That's what I had to do recently. The 'extra' (waitlisted) segment messed up LH reservation system so much that even paid seat assignments weren't possible, let alone upgrades.

Thanks for the response. Yes, I've realized this as well. The paid seat assignment options promptly disappeared on the LH side when I made the UA upgrade request. Fortunately I had already selected seats on the LH site and was holding off on paying until the UA agent gave me the all-clear (it was a weird day when UA's receipt system was under maintenance and slow to generate e-ticket receipts).

Well, I don't expect the LH upgrade offers to drop significantly in price until a few weeks before the flight. I do want the UA upgrade request to clear, so I will keep it for now. I guess I just have to hope that when I fly the UA segment and the waitlisted segment goes away and there is only the LH-operated return flight left, the LH system will again see this as a regular reservation and offer me the cash upgrade options. If anyone knows of any way to fix things if the upgrade option does not reappear on the LH side after the UA segment is flown, please let me know!

People upgrading on LH with $'s, points, or miles need to stop freaking out about the itinerary looking "weird" on the UA website / App. And even ignore the "there has been a modification to your itinerary..." warning (meaning ticket is "out of sync.")

UA uses SHARES. LH (and most other *A carriers) use AMADEUS. They are separate, incompatible systems, and often don't "play" well with each other when upgrading.

As long as the LH segments look good on the LH app / website you are good to go.

Recent story: A few months back I booked BOS-FRA on LH non-stop. Booked as UA code share. Called UA to get flight #'s changed to native LH flight #'s so I could upgrade. Done. So all flights on the itinerary were booked as LH, operated as LH, ticketed by UA. But with zero UA operated segments in the itinerary.

THEN...I went to LH.com and did paid upgrades to business class. They were confirmed on the LH side. The UA side freaked out. All segments dropped. I got an email that "your itinerary has been cancelled". Which is technically true because the originally booked premium economy segments were cancelled by LH and replaced with P business class. So UA showed it as "canceled". And it dropped off the "My itineraries" list. Meanwhile over on the LH side, everything was fine. Confirmed upgrades with itinerary looking perfect, all linked to the original UA ticket number. When day of departure came, I checked in online on LH.com as usual. No issues. Both on the outbound and return. Miles and Plus Points posted as usual. The originally booked segments in the UA reservation was canceled, but the electronic ticket was still active as it should have been.

TLDR: Stop looking at the UA website / app itinerary for partner upgrades. It is meaningless. As long as the UA flights look good on UA side, you are good. As long as LH flights look good on LH side you are good. Don't stress. And whatever you do, don't call either UA or LH to "Fix" it, because all it will do is break it and you'll lose your paid upgrades.

My only stress is if UA proactively fixes it.

A booking for this summer in PremEcon, UA out, LH return. Original UA codeshare return.
Called to change to LH flight number, UA knew immediate what and why I wanted. But things got interesting -- after 15 minutes, cam back and said this will take longer. Had another codeshare LH operated to start the day and the two LH flights were married segments. So in the end both flights were re-labeled.

Then as I started into applying *A mileage upgrade, I got a very reasonable cash upgrade for upper deck, footsie seats (only a few seats still available). Decided to purchase.
And now the TATL segment is gone on united.com.

Just hope UA does not try to help me or LH makes a schedule / aircraft change.

Question: if I put an upgrade request or take a cash offer from UA, is that pushing my chances too much?

Not sure I get the 'UA tries to help' or LH schedule change. Assume you bought the UG on lufthansa.com? UA does not see that - any change that requires re-ticketing is going to mess up that purchased upgrade - re-instating that is not an easy task. I think you should hope that there isn't a change and that UA does not want to 'help' here

They have to change both flights to LH flight numbers, that's normal, they can't leave the intra-EU as a UA codeshare with the TATL changed to LH

upgrading a remaining UA segment on this ticket should not be a problem, I have done that in the past and it was compatible with a UA upgrade (although not cash; used +Ps). The UA upgrade should not trigger any re-ticketing. IME, as long as one avoids anything that triggers a re-ticketing (incl., e.g. SDC), it is fine.
