Delta Global & Regional Upgrade Certificates: How To Redeem Them

Sadly only the KLM A330s are the only long haul planes without PE. We booked straight into Z on one using GUCs from ATL to AMS in 2024. However at t-24 we were demoted to PE due to an equipment swap. We talked to agents in the lounge and gate and the only way to get back to biz class was to pay $800.

Delta Premium Select is the biggest scam ever. It basically destroyed the option to use Global upgrades to go from Economy to Delta One and in most cases Premium Select costs over 3 times Economy.

The global upgrade certs are arguably the most valuable and coveted benefit offered in the SkyMiles program. I was a Diamond Medallion member for a number of years and selected these as a Choice Benefits option every single year. I was NEVER able to use one of them for an international flight because DL never offered any available inventory, even on flights that were not sold out. I explained to DL that offering "benefits" that were not available for customers to use was much worse than offering no benefits at all. That was the nail in my loyalty coffin. I no longer have any loyalty whatsoever to DL and am systematically just burning off my accumulated miles for domestic trips since their international award redemption rates are so ridiculous. FF programs in general offer little value anymore.

RegardS,if the KLM have PE,upgraded is from economy to Business,

Thank you for this article - this may be the most helpful article I have read on OMAAT, among many other helpful articles. I have read the T&Cs and FlyerTalk threads on GUCs and RUCs and still found it extremely confusing. This is the clearest articulation of the program that I have seen.

Given all of the limitations, I'm not sure that choosing RUCs or GUCs is the best use of a choice gift.

I completely agree. I was Platinum for 4 years and never once was able to use a Regional Upgrade Cert. I certainly tried any number of times, but the space was never there. I wish airlines were forced to disclose the practical availability of benefits they market.

Hi,

Would suggest updating the article with - GUCs can also be used on Air France / KLM stock booked flights as well. Delta has the ability to control those tickets. That’s where the AF marketed/operated or KL marketed/operated can be use. The VS marketed/operated has to be on DL stock (example JFK-JNB will show up as VS operated/marketed on Delta.com since there is not codeshare)

What you read is confusing because it is confusing.
OMAAT didn't do more than citing the T&C.

The confusion will start when you actually try to use it.
OMAAT didn't cover any FUBAR situations.

I still stand by GUC but not RUC anymore as a choice benefit.
Consider how Ed trashed the program, they aren't many better choice benefits to choose.

I wouldn't suggest updating it because it's just going to add more confusion.

While you can use it if AF KL stock. You can't use on AF stock KL market DL operated.

The whole use of it is too confusing.

What you should add is on the trip that you did use GUR/RUC, go check in early like 2.5-3 hours early.

As a counterpoint, I've been Platinum 3 of the last 4 years, and the only time I've struck out on using Regionals has been on JFK-LAX, because the D1 was sold out days in advance of departure.

Never had a problem using them to Hawaii, which is my other go-to. Always completely redeemed them each year.

@ImmortalSynn

Hawaii meaning D1 to HNL?
Did you ever clear in advance or at the gate?

The issue with domestic D1 is it's pure gamble for complimentary upgrades. While it's almost impossible for PM on transcon, it's rare but still possible for DM.
Hawaii on the other hand can sometimes be quiet open.
So even as a PM you could have cleared to D1 without using RUC anyways thus wasting a RUC.

Delta’s upgrade certificates are so useless that neither my wife not I - both Diamonds - have chosen them in the last four years.

Even the Starbucks option, also lame, is infinitely more useful

I have received RUCs - regional upgrade certificates for two years now. They are really hard to use. First, upgrade space is rarely available on the flights you want. If you do get it, then you typically cannot check-in for your flight without calling again and reticketing the ticket within 24 hours of departure, which is a major inconvenience. Delta seems to set it up this way in case flight changes occur, it is easier to make changes before the full reticketing is done. I have also found that not all phone agents are fully trained on how to process RUCs.

I just used an RUC for a ticket and had a missed connection. Lost my upgrade on the rebooked flight.

Moral of the story - it is much easier to just buy a first class ticket.

I have moved all of my spending away from Delta Amex and am not pursuing Medallion status through credit card spending for two reasons: 1. The RUCs rarely have space available and are too hard to use, and 2. For first class mileage redemptions, it is the norm to only see 0.9 cent value per mile!!! Much better to use a 2% cash back card, pay for first class, and stop gambling on Medallion upgrades when the upgrade list is a mile long, even for Platinums at this point.

Utilized a Global Upgrade Certificate on AKL-LAX to go from Economy to Delta One. Do note that if you call them to utilize the Global Upgrade Certificate a lot of times agents will apply it so you'll have a confirmed seat in Delta Premium Select but not ticketed (they don't fully know how to redeem it as payment and have to go through ticketing to do this) - if you are not able to select your seat or check-in then this is an issue and you'll specifically have to call Delta and ask for ticketing to confirm the seat

Too much of a rat race to be honest.

While it's always great to score an upgrade using these (confusing) instruments, please be aware that getting them through the complex re-ticketing / re-issue process will almost always involve several calls (not emails/texts!) to agents, very few of whom know how to correctly process the upgrade. With diligence, they'll work, but it's a very cumbersome, frustrating, and highly interactive process.

Trying to use a Regional for FC upgrades is almost impossible...

RUC for 1st works quite often depending A) on the route and B) how far out your booking. Scored PVD-LAS with RUC for next month, but we booked it back in Nov/Dec. Direct transcontinential flights, pretty rare to see RUC available, but flights through MSP and DET often will have RUC as an upgrade possibility.

Thanks for the great article! It's very helpful. However, I am still a bit confused how to redeem GUC for KLM. Do I call KLM or Delta for availably? Do I look for availability through KLM?
