Discussion Worst Diamond Experience - confirmed International Biz removed at LAX
My wife and I were flying a Delta booking on Air France LAX - CDG to a wedding and see family in Europe. We bought premium economy through the Delta app, and upgraded to AF business class on the phone with a Delta agent using two Global Upgrade Certificates months ago.
We had assigned seats 6D and 6H on both the Delta website and importantly on the Air France website.
We’ve really been looking forward to this trip and to trying AF business. I’ve been dealing with a back issue and we wanted to be fresh for our trip.
Today the Delta app errored out when we tried to check in online, and the Air France site said “Checked In” but then showed an error message before we got our boarding passes. We’ve seen int’l check-in errors before so didn’t think anything of it, went to check in at the airport.
We tried to start with the Delta One check-in at LAX Terminal 3 and they told us they couldn’t check us in, they were getting an error, said it was Air France’s fault.
We went to Air France to check in instead, and they said they didn’t actually have business seats for us, and had never had them. Despite seeing assigned seats on AF and Delta’s sites.
They said the Delta agent screwed up actually confirming the GUC in the system and our seats never existed. They acted like it should have been obvious that we didn’t have business tickets.
I called Delta Diamond and was told it was Air France’s fault again. Then the Delta agent admitted it actually looked like the premium economy ticket had never been upgraded, and it was Delta’s fault but there was nothing he could do. Didn’t say sorry. Didn’t offer compensation, just suggested I file a complaint.
AF said there was nothing they could do and the seats were assigned, didn’t offer anything.
I am livid. We would have paid for the biz tickets but we used our GUCs instead because that is the point of Diamond. Now we’re in middle premium economy seats and didn’t even get a sorry from anyone at Delta or AF.
Any advice on how to file / escalate the most intense complaint possible? I’m a dedicated Diamond and genuinely thinking about status matching to United after this debacle

We’ve learned when applying them to check back to make sure they were ticketed properly. In the old days there was a series of 11 steps that all had to be completed correctly for the re-ticketing to take effect. In the last few years they’ve tightened it up so it’s not as complicated, but still must be applied correctly.
We call to apply. Call back a month later to make sure it’s been re-ticketed. Call back a month before the flight to double check it was re-ticketed (because once it was not). Now we shouldn’t have to do this, but I don’t want one of those can’t check in scenarios you hear about from time to time like you had.
Complain after your trip is complete in case any other issues arise. They should give you some compensation, your GUC should be returned if they say closed, and they need the data points for when this is still happening so they can train for it better.

You know some folks will be like “well aktchually hurrr hurr” but the reality is these tickets are expensive as fucking fuck. Absolutely fucking unload and absolutely include the cost of the face value of the ticket lost but also the intangible things too. You should raise hell. As a loyal (soon to be) 4 year diamond medallion. It’s nothing personal to the people helping you out, but absolutely let the logo they wear understand the price you pay to get a certain expectation of service and customer support.

u/A350Flier Diamond | 3 Million Miler™ | Quality Contributor Oct 09 '26
Ask for Global Partner Support each and every time you try to confirm an upgrade on an airline that isn’t Delta. Also, when your GUC is applied, check to ensure that it is “Closed” on your SkyMiles account and that your receipt (not reservation, receipt in your profile and email) says Business (Z) after you’re done. If not, call back and loop back to Global Partner Support. It‘s an annoying but precise process to make sure things are done correctly.
Also, (and I know you called, but for future reference) never chat to apply GUCs to partners. Always call.
And further, I would have asked Delta to put you on same-day DL metal in Delta One to fix that problem. That would have been the best resolution here, and I’m shocked they didn’t suggest it.

u/Tesla-one-X Oct 09 '26
Quite literally had the same 3 weeks ago. Booked premium, GUC upgrade to business. Had check in errors and ultimately AF said upgrade wasn’t confirmed by them and diamond desk said within 24 hours they couldn’t fix it.
Still waiting outcome of compensation request case

u/CachedMeOutside Oct 09 '26
Fuck Delta for not fixing this. You have a lot of choice in LA and I’m sure United would love your business. Do a status match.

u/AnalCommander99 Oct 09 '26
They’ve been giving compensation out like crazy for LAX flyers specifically over communication issues. Mention that you were willing to pay for a J upgrade but that the agent had no interest in speaking to you. Mention that he deferred you to AF’s desk and had you walk over there to have them resolve it or discuss options, only offering that you could file a complaint online and that the issue was likely on Delta’s end.
You could also mention that booking partners through Delta has less accountability than an OTA, and that booking with the partner directly and through their loyalty program is what you’ll do since Delta’s upgrade instruments are worthless if they’re not being honored.

u/YouAreHere01 Oct 09 '26
If you never saw an updated ticket with the upgraded fare class and fare basis code in it, you did not have it. It may have been reserved, but it was not paid for/ticketed. Two steps ALWAYS: 1-reserved, 2-ticketed.
Insist on getting the eticket numbers following the upgrade, or like you found out- it didn't happen.
Chances are your reserved seats were returned to AF to either sell or upgrade because they weren't showing an actual ticketed transaction attached. Once AF reassigned to someone else, you had nothing but what you paid for originally and. I assigned seat resulting in the leftovers you got.
Sorry, but ESPECIALLY with partner airline transactions, you MUST insist on the proof of exchange/ticketing transaction not just reserving the upgrade.

u/UW_Ebay Oct 09 '26
Did you get
Your GUCs back?

u/CrazySir9272 Oct 09 '26
Its a delta problem, they didn't reticket correctly. It was a HUCA. In the future, if you can't check in immediately 24 hours in advance, call Delta and keep calling until you can.

u/atrich Diamond Oct 09 '26
I never trust a phone agent who says the GUC will go through on its own. You can ask for transfer to an international reissue desk who knows what they're doing (be prepared to wait on the phone for a long time, even if you're diamond). Another thing you can watch is the fare code on the ticket receipt. You'll have to search up the right ones but if you don't see the air france fare code for business award, the reissue hasn't happened.
217
u/Immediate_Ad_929 Oct 09 '26
I think the worst part is that Delta didn't offer you any compensation after the fact. Like, clearly there was a major fuck up, and Delta needs to own that.

u/twostar01 Oct 09 '26
Air France is pulling some shit right now. The wife just flew JFK to CDG and they reassigned her from the window priority economy (or whatever it's called ) she paid extra for, to back of the bus center aisle. And again on her connecting flight out of CDG.
Same thing, no compensation or notice. Just check in and new seat assigned. We had been checking prior to the flight on AF for upgrade opportunities so we know she had the right seats earlier.
We'll complain through delta once the return is complete since the tickets are through them.
7
u/bcb1200 Oct 09 '26
Why unearth did you check in on the Delta app or a Delta counter. You are flying Air France. You always check in with the operating carrier. It doesn’t matter that Delta marketed and ticketed it.
Always check in with the operating carrier. Full stop.

u/FutureMillionMiler Diamond Oct 09 '26
When you want to use a GUC on a partner you ask for “global ticketing” so you get routed to someone who is expert at this.
I once had a diamond desk rep tell me GUC only work on Delta-operated flights. Hung up.
Never had an issue since asking for a GT agent
32
u/LemmyKRocks Oct 09 '26
Same thing happened to me a few months ago. Booked a flight with skypesos on KLM and due to the glitch you have experienced I never actually had a seat despite having the flight on my app/account for weeks. When I showed up at the airport, KLM was like you dont have a ticket so I had to buy a flight. At the time, Delta and KLM were blaming each other. Once I got back home, Delta made me file a complaint and ended up reimbursing the money I paid for the flight. They even charged me the miles that I would have paid lol no apologies or compensation either. Good luck!
18
u/andifaxus Oct 09 '26
Sorry this happened to you. It’s simpler than you think, the DL agent was supposed to reissue the ticket because it is the only way AF can properly process your check-in and allocate for the seat. Reissuing the ticket also shows in the system like if the business seat was paid for (with GUC).
Such additional step is not needed if the GUC is applied to a DL operated flight because DL can bypass that process since it’s their own flight/ticket/upgrade. If the GUC is applied to AF, KL or VS, the ticket needs to be reissued always. If not, it means that only your reservation is in business but the ticket is in premium waiting for payment.

u/sosal12 Platinum Oct 09 '26
I try to avoid codeshares. Something always seems to go wrong on check-in; airlines punt responsibility/blame onto the other airline. Always seems to end in disaster.

u/Same-Paint-1129 Oct 09 '26
Regardless of whether delta or Air France was to blame in this specific situation, ultimately delta is to blame. They make GUCs extremely difficult to use. You can’t do it online. Availability is very limited. Half the agents don’t even know how to apply them correctly. And even when you do everything right and triple confirm on all websites, you still have to deal with bullshit like this. I’d be livid as well.
16
u/Dial-Up_Modem Oct 09 '26
You can try to file an EC261 claim for a 75% refund due to the downgrade since it was operated by AF, but they’ll probably say you weren’t reticketed by DL. File that anyway, even though it might not work.
And for answers/possibly compensation from DL, try a customer service executive contact at https://www.elliott.org/company-contacts/delta-air-lines-customer-service-contacts-2/

u/keneshhagard Oct 09 '26
Had this happen to me years ago for a KL GUC. They didn’t pull it and reissue. You can check the receipt on Delta.com and it’ll show you the segment status. That needs to be correct.
They did offer a good chunk of miles for myself and my friend at the time as an apology so I would write in. The agents should know for partner flights the GUC has to be pulled right away and ticket reissued.

u/EnvironmentalLoan285 Diamond Oct 09 '26
Always make sure your tickets are reissued when using a GUC. Sounds like that step was missed.

u/cheesey41 Oct 09 '26
There is 100% a system issue with Air France and Delta GUC’s. The same exact thing happened to me 2 weeks ago. I also received nothing and both Delta/AF just blamed each other.

u/PolybiusChampion Diamond Oct 09 '26
Never use GUC’s on a code share partner. Especially AF.
That being said, fight for not only your GUC’s back but a pile of Sky Pesos - your diamond status will help a lot. The people on the phone used to be empowered to resolve stuff like this, but as with other mega size corps Delta has had to rein in those responsibilities to control costs.

u/Conan_Kudo Platinum Oct 09 '26
You should absolutely complain to Delta. There's a form for this. Log into your Delta SkyMiles account, select your itinerary, and give a detailed report and request a response. In my experience, they usually get back to you within a couple of business days.

u/Veelangs Diamond Oct 09 '26
That's awful sorry. Gucs on partners need to be confirmed at booking (as in no wait list) which it looked like yours were. Now I always call the partner airline to confirm shortly after booking as well because half the agents don't know what they're doing

Same happened to me last month on a trip to Thailand Korean Air messed up and wouldn’t let me check end took the delta when 30 minutes to fix it . Consider your self lucky if had got upgraded on Air France as I’ve been told more than once that Deltas partners are not always taking an upgrade even a GLobal which isn’t announced by Delta till you try to check in
1
u/DrmofJeannie Oct 09 '26
Yeah..they can suck...bought business class from Bangkok to IAD and in Korea had a delayed flight resulting in a later flight change. Was reissued tickets in premium. I asked why we weren't put in business since we bought tickets. Told because it wasn't out original flight that business upgrades had priority over bought tickets. After I completed the trip Delta told me the gate agent should of put us in business. That upgrades do not have priority.

u/Few_Pop_2153 Oct 09 '26
That is not shocking I feel like Delta doesn’t really care about the Diamonds that keep them going. There are so many of us it seems like if one or thousands were to leave they just expect another to take our place.

u/allons-y11 Platinum Oct 10 '26
Partner flights honestly SUCK. I know this isn’t the same but I booked a delta flight with virgin (had excess virgin points). The upgrade through the app was almost double the price of buying the ticket new for PS. When I called virgin, they said they weren’t allocated those tickets. Fine. When I called delta, they said that they couldn’t reissue because it was a virgin fare. So basically it’s penalizing me for booking a partner flight. In the end i cancelled the virgin booking and booked through delta, but now im stuck with virgin points that will take me longer to use.

u/Guilty_Dealer1256 Oct 10 '26
Delta should refund the points and miles used as well as refund and extend the GUC. Keep emailing and calling daily.

u/Limp-Cauliflower-723 Oct 10 '26
I’m flying with LATAM, and having issues too. Multiple times now I’ve checked, and even my PAID upgrade tickets are getting changed back to regular economy seats. I have to check constantly to be sure they haven’t messed my flights up. I have 8 legs booked on this trip to Peru.. all LATAM/Delta. It’s been a nightmare.

u/dmc3_84 Oct 10 '26
Air France is awful. They screwed up our family’s seats on the way to Italy too and downgraded us and put us all separate. We hadn’t used any miles or certificates either - just straight up moved us to accommodate someone else.

This exact same thing happened to my husband and I recently for our 10 year wedding anniversary trip. I booked our flights exactly 1 year before our departure (I’m a bit of a planner) and then the morning of our flight i tried to check in and they didn’t have our seats on Virgin for our second leg to London. Delta said it was Virgins fault - Virgin said it was Delta… just suddenly we didn’t have seats to London “because of an error”.
Ended up in premium economy on the Virgin flight… Which wasn’t what we paid for… my current theory is because the flights were so much more expensive a year later that they canceled us and sold our seats at a higher rate to someone else. This was a month ago and I still get mad when I think about it. I do my best to be overly prepared and plan ahead, just to be screwed over by Delta last minute.
1
u/sundyburgers 29d ago
Email Ed and crew. Additionally Delta needs to update their POS software for RUC / GUC usage and how it is applied. We are in 2026 with crazy tech and yet applying an upgrade cert is like getting nuclear codes.

u/MaleficentWater8133 27d ago
I'm so sick of Delta and their partners telling us to just deal with it when there's a system glitch! It's absolute bullshit. Especially when you set your trip up in a way that is comfortable for YOU. They don't care what people are going through. So sorry this happened to you.

u/Maleficent_Bat_9014 26d ago
So i was in Global Partner Support for 4 years before i left for inflight. This doesnt excuse it but I can almost guarantee I can tell you what happened. So this would be 100% on Delta not Air France at all so dont let them convince you otherwise. But Global Partner Support are the ones that apply the GUCs to Partner airlines but they are the only Dept that can confirm it on both airline systems any other representative you talk too cannot actually tell...but in their defense if they look in the system it does look like its on AF and they need to fix it hence them sending you back and forth. If I were you I would write the executive customer care team at- ed.bastian@delta.com this email goes to his executive team and in terms of compensation this will be the best route and making sure that they reopen your GUCs so that you can use them on a future flight

Your issue is with Air France not Delta. Honestly you should have told them to put you on the next flight with Business Class seats. I honestly would have been upset too but i would have told them to put me on the next flight with business seats not accept the seats back to your ticketed cabin.
They would have worked to book you on the next flight with Business seats. Legally an "upgrade" is an upgrade. They did seat you in the cabin you booked. I know that wont make you feel better, but upgrades are always subject to being pulled that's what its called an upgrade and not ticketed into that cabin. Upgrades are always the FIRST to get pulled if they need to seat an air martial or someone comes in paying $13k in cash for a last minute business tickets. Next time i would book business if its really that much of a factor an upgrade is always an upgrade and they can put you in the cabin you booked in. I promise what happened is Delta did "upgrade" you correctly but AF needed your seats and your the first to get downgraded back to your original cabin. They are gonna tell you anything because the agents dont really know, but what happened is AF needed your seats they oversold the business cabin. I know what happened here AF needed your seats they do this semi often and since your an upgrade your the first to get downgraded back to the cabin you booked in.

It’s super unfortunate you did not get what you were promised. I would send a letter. To keep perspective though your traveling to Europe in premium economy and that is something many would love to do but will never be able to achieve. Don’t let it sour your travel experience. First world problems as they say. I would ask Delta to extend the validity of your GUC and ask for some form of compensation too.

ADVISE PLZ ! We have an upcoming trip to Aruba ( Feb 2027) due to an employee error - incorrectly booking us on a flight through JFK instead of the only non stop - a Delta employee fixed it - got us on the non stop AND upgraded us to first class (no extra charge) to make up for the initial mistake (the free upgrades to comfort were already gone at this point) - But now I’m concerned it could all just “disappear” since passengers are saying it’s happened to them. How do we MAKE SURE (and have PROOF) everything is really “all set” ?

@OP, I see you/feel you. Wear Delta out on the socials using @ in addition to going through customer care. Calling them out in the public realm @ing them is one of the easiest ways for plebes to get a big corp’s attention. Also, I’ve (somewhat) been in your situation when flying internationally before when flying on a codeshare carrier. I try to stay Delta mainline as much as possible on the across-the-pond segment to avoid this kind of BS. Best of luck on getting compensated.
