Using Delta Global Upgrades


DL page: https://www.delta.com/us/en/skymiles/medallion-program/medallion-upgrades
(click or scroll to "Upgrade Certificates Overview" and expand the "Show Additional Details & Terms" sections to see T&C, especially for the specific conditions governing use on partner airlines)

"Global Upgrade Certificates, available exclusively for Diamond Medallion Members, offer upgrades on both international and domestic flights with Delta, and select flights with KLM, Air France, Virgin Atlantic, Virgin Australia, Korean Air and Aeromexico."

Delta offers Diamond Medallion members the benefit of up to 4 Global Upgrade Certificates (GUCs) per year, which each allow a one-way upgrade to business class/Delta One for one person on any route in the Delta network, as well as a limited number of partner flights under specific restricted circumstances described below. 4 GUCs is enough to upgrade the Diamond Medallion member on 2 round trips or 4 one-way trips, or the Diamond Medallion member plus one companion on 1 round trip or 2 one-way trips.

Choosing upgrades as a choice benefit
  • Upgrades are valid one year from the date of issue, usually the day of or day after they are selected in Choice Benefits -- so best to wait as long as possible to select them unless you have a specific use planned for them
  • All Diamond Medallions also receive a Platinum Medallion choice benefit, even if just renewing existing Diamond status in a year, so DMs could for example select 4 RUCs as their Platinum choice benefit and 4 GUCs as one of their Diamond choice benefit, or 4 RUCs as their Platinum choice benefit and 8 more RUCs as one of their Diamond choice benefits
  • However, it is not possible to select 8 RUCs as one Diamond choice benefit and 4 GUCs as another, nor select 4 GUCs more than once for a single year's Diamond choice benefits -- so the most GUCs anyone can currently earn in a single year is 4
  • You may select your DM benefits at different times, so it is best to select fixed-expiration-date benefits (like gifting status or SkyClub memberships) as soon as possible, but wait until you have a specific use in mind to select upgrades, so that the expiration date is as far into the future as possible. This is especially important if you are waitlisting upgrades for a particular trip, since if the waitlist doesn't clear, a later expiration date will maximize the amount of time you have to try again to use them on a different trip.
  • For status earned based on flying in 2017, upgrades can be selected until the last day that status is valid, January 31, 2019, so they could possibly expire as late as January ~30, 2020 if they are selected as late as possible.
  • Upgrades can be used after you are no longer a Diamond Medallion as long as the upgrades are still valid, though non-DM-line phone agents will be less familiar with them, so they may be harder to use or run a higher risk of being processed incorrectly, so it may be worth booking your GUC flights before your DM status expires if possible.
  • All flights to be upgraded must be flown, not just requested, by the expiration date of the upgrade certificates, though there have been some examples of short extensions offered by phone agents (for example, to the end of the month of the expiration date) as long as the upgrade is able to be confirmed before the certificates expire. In this case it is important to push the agent to make sure the ticket is reissued right away, since it will not be possible to reissue the ticket after the GUC expires. You can tell if the ticket has been reissued because the ticket number on the booking will change from what it was when you originally booked in coach, and the GUC will be marked as "closed" in your wallet on Delta.com.

Finding upgrade space
  • Delta phone agents and the @Delta Twitter account can check for available upgrade space
  • There is no general way to check for available upgrade space online
  • However there is one exception where some flights appear to be able to be checked online: for Delta flights carrying a KLM code -- for example, most flights between the US and Europe -- ExpertFlyer.com (paid membership required) shows KLM upgrade space, and will show upgrade space for those KL-coded, DL-operated flights, which based on anecdotal evidence seems to often (but not always) correspond to upgrade space made available by Delta. This can be a way to check many dates and flights easily, but confirm with Delta that the upgrade space does in fact exist before making firm plans.
  • Upgrade space is not necessarily correlated with award space
  • If upgrade space is not available on your desired flight, you can waitlist, and it is possible the upgrade may clear before departure. If not your name should appear on the upgrade list at the gate. See next section for details.
  • Upgrade space is rarely seen in advance on busy, high-upgrade-demand routes like ATL-JNB and LAX-SYD.

Requesting an upgrade
  • You must call or Tweet at Delta to request an upgrade, they cannot be requested on the website
  • If upgrade space is available, the agent will process the upgrade immediately and you will be able to select business class seats
  • If the upgrade is confirmed in advance, your ticket will be reissued in business class at some point before the flight and you will receive a new itinerary email when this happens; occasionally the ticket does not get reissued and you will not be able to check in, but a quick call to Delta usually fixes this easily
  • Occasionally an email is sent to alert you if a waitlisted upgrade has cleared, but often the best indication is if a segment of your itinerary disappears entirely from Delta.com, which usually means the upgrade has cleared on that segment. Call Delta to have them process it so that it reappears in your itinerary, and you will be able to select business class seats.
  • There have been reports of upgrades coded incorrectly by agents -- unfortunately there is no way to know for sure if your upgrade is coded correctly, and requested upgrades seem to show up a few different ways on Delta.com, sometimes with an "upgrade requested" designation on the flight, and/or with a "phantom" duplicate flight in the seat maps which will not let you select seats
  • If an upgrade has not cleared by check-in time and you do not appear on the upgrade list on the Delta app or Delta.com, call to have an agent correct the upgrade
  • In certain airports where other airlines handle Delta's flights (particularly AMS), it is not officially possible to clear at the gate; KLM does process upgrades at the gate in AMS for certificates waitlisted 24 hours in advance of departure, but this is not an officially guaranteed benefit. To be safe make sure you have your GUC certificate numbers and redemption codes written down in case the KLM agents need this information.
  • If you are connecting, for example flying MCO-ATL-LHR, and upgrade space is not available on ATL-LHR, best practice is to waitlist on the ATL-LHR leg only, so as not to waste a global upgrade on the short MCO-ATL flight, and then add the upgrade request to MCO-ATL when/if ATL-LHR clears; most agents will understand this approach and may even proactively suggest it
  • If you have selected your choice benefits very recently (within the last 24-48 hours), the phone agent may not yet be able to see your upgrade codes, but you can read the codes to the agent from the My Wallet page on Delta.com
  • The priority order of GUCs, RUCs, mileage upgrades, and complimentary upgrades is not 100% clear, but it is known that GUCs and RUCs have higher priority than complimentary upgrades, and that GUCs and RUCs appear to have equal priority. It is listed on Delta.com that GUCs and RUCs clear first by medallion level and then by time of request, which is different from the upgrade priority used for complimentary upgrades (which is also listed on the website)

Other upgrade rules
  • Upgrades are valid on Delta flights on all economy fares except Basic Economy (E)
  • It is possible to request upgrades in one direction of a roundtrip only, for example if you had 4 US-Europe trips planned and only 4 GUCs, you might decide to upgrade the eastbound flights only as they are overnight flights and remain in economy for the westbound flights.
  • On flights operated with a Premium Select cabin, Delta has indicated that it will still be possible to use a GUC to upgrade directly from economy to Premium Select or to Delta One using the same number of GUCs. However, if an upgrade is cleared from economy to Premium Select, the GUC will be considered used, and another GUC would be required to upgrade again to Delta One. The best strategy is probably to waitlist only for Delta One upgrades, and perhaps if the GUC is close to expiring or you don't expect to have another use for it, to add a request for a Premium Select upgrade close to departure if the Delta One upgrade hasn't yet cleared and/or the Delta One seat map looks very full.
  • Upgrades may be used for the SkyMiles member and up to one companion; The companion need not be in the same PNR, but must be traveling on the exact same flight as the GUC holder.
  • Unlike AA and UA upgrades, DL upgrades cannot be gifted to someone whom the SkyMiles member is not traveling with
  • As of January 22, 2018, it is now officially possible to use a certificate for a companion but not for yourself, as long as you are traveling on the same flight as the companion -- for example if you are eligible to buy a business class ticket for business travel and want to bring your spouse by buying an economy ticket and upgrading them. It is not clear if you could upgrade your companion but not yourself. In the past the question has been raised of waiting for a complimentary medallion upgrade for the main member and then using a certificate for the companion, but now that companions for complimentary medallion upgrades are processed at the same priority as the main member, this is no longer a likely concern.

Using upgrades on KLM

Dedicated thread: https://www.flyertalk.com/forum/delt...grade-klm.html
  • "For travel on KLM-operated, Delta-marketed flights this certificate may be used to upgrade on published fares booked in Y, B, M, H, Q, K, L, U, T, X or V class and all fare classes upgrade into Z class. For travel on KLM-operated flights marketed by KLM, fares booked in Y, B, M, K, H, L, Q, T, N, R, or V class are eligible to upgrade into Z class. For travel on KLM-operated flights marketed by AF, this certificate may be used to upgrade on published fares booked in Y, B, M, K, H, L, Q, T, N, R, or V class into Z class. "
  • NOTE: some of the combinations above are only (relatively) recently eligible for GUCs. Phone agents may not be familiar with the new rules, and may need to be gently pointed in the direction of the DL T&C on their own website.
  • In the course of processing the upgrade of a Delta-marketed, KLM-operated flight, Delta reissues the KLM flights on KLM flight numbers when they issue the upgrade, but the flights must be bought on DL flight numbers initially (unless buying expensive Y, B, or M fares with KLM)
  • It is not possible to waitlist for upgrade on KLM flights, nor to go to the airport upgrade list, so space must be available in advance in order for the upgrade to clear. Many agents will offer to put you on the waitlist, but putting you on the upgrade waitlist for a KLM flight will simply never clear so you're better off monitoring it yourself (see next bullets).
  • KLM upgrade space can be checked on ExpertFlyer.com (requires a paid membership). ExpertFlyer also allows users to set alerts for particular fare classes becoming available, which could be useful in lieu of being able to waitlist -- you can set an ExpertFlyer alert for "Z" availability and then call Delta to grab the upgrade if you receive an ExpertFlyer alert that it becomes available.
  • KLM upgrade space on a single segment is different if you search that segment alone vs. if you search a connecting itinerary involving that segment. So if you are looking for KLM upgrades ORD-AMS-JNB, you need to search ORD-JNB in ExpertFlyer to see the true availability; even if there is space on ORD-AMS and AMS-JNB, if it Z space doesn't show up for ORD-JNB you won't be able to upgrade. Unfortunately this means that ExpertFlyer availability alerts, which can only be set on a segment-by-segment basis, are not useful for monitoring KLM upgrade availability on connecting flights.
  • In some cases, adding a DL domestic connecting flight can change KLM upgrade availability. For example ATL-AMS on KLM may show availability but MCO-ATL-AMS may not. Example. Unfortunately some more complex routings, such as forcing an extra connection to find KLM upgrade space (flying JFK-ORD-AMS-CPT instead of JFK-AMS-CPT), do not show up on ExpertFlyer so you are at the mercy of hopefully finding Delta agents who know what they're doing.
  • Bookings with KLM ticket numbers (starting in 074) can be upgraded using the same rules as bookings with Delta ticket numbers (starting in 006). Delta-operated, KLM-coded flights can be upgraded under the same rules as any other KLM-coded flight. Delta-coded, Delta-operated flights booked on a KLM ticket number can be upgraded the same as if they were booked on a Delta ticket number, so in any fare class other than E.
  • There have been numerous challenges with KLM upgrades, so be careful, be persistent, and make sure you request the upgrade within the no-risk cancellation window of the ticket so you can cancel if it doesn't work as expected.
  • More KLM upgrade reading: 1, 2, 3, 4, 5, 6

Using upgrades on Virgin Atlantic

3-year-old thread: https://www.flyertalk.com/forum/delta-air-lines-skymiles/1779666-guc-now-able-used-virgin-atlantic-vs.html
related, upgrading VS with SkyMiles (also requires G class, so the info may be useful too?): https://www.flyertalk.com/forum/delta-air-lines-skymiles/1857464-definitive-thread-use-sky-miles-upgrade-vs.html
  • "Valid on Delta-marketed (DL flight number), Virgin Atlantic-operated flights for use globally on published fares booked in W, Y, B, M, H, Q, K, L, U, T, X or V class to G class (Upper Class). " Upgrading on Virgin-marketed (VS flight number) flights using GUCs is not possible.
  • Global Upgrades on Virgin Atlantic flights must be confirmed 24 hours prior to departure.
  • Global Upgrade Certificates may not be used to waitlist for a Virgin Atlantic-operated flight. Many agents will offer to put you on the waitlist, but putting you on the upgrade waitlist for a Virgin Atlantic flight will simply never clear so you're better off monitoring it yourself (see next bullets).
  • DL flight numbers are not available for most Virgin Atlantic flights to regions other than the US (for example LHR-JNB), so it is not possible to use GUCs on those flights.
  • Virgin Atlantic upgrade space appears to use the same availability as awards, so if a business class award is available for a Virgin Atlantic flight on Delta.com, it should be available for an upgrade (as long as that flight is booked on a DL flight number). If an award is not available, an upgrade is probably not available -- but if you notice any exceptions to this rule please share in the thread. You can also monitor G space using ExpertFlyer (see KLM section above).
  • Because G is the same code as Virgin Atlantic uses for award tickets, after you fly the tickets will register with Delta as having been awards and will not earn any miles. Watch your mileage earning carefully and you will likely have to call Delta and explain that it wasn't an award ticket but an upgrade from a paid coach ticket, and they will correct the mileage earning to be equivalent to what you would have earned on your original coach ticket.

Using upgrades on Virgin Australia

Valid on Delta-marketed, Virgin Australia-operated flights on published fares booked in Y, B, M, H, Q, K, L, U class to Virgin Australias Business Class.

Using upgrades on Air France

Dedicated thread: https://www.flyertalk.com/forum/delt...20-onward.html

"For travel on Air France-operated flights marketed by Air France and booked in Y, B, M, K, H, L, Q, T, N, R, or V class, customers can upgrade into A class (Premium Economy) or Z class (Business Class). For Air France-operated flights marketed by KLM, customers with a published fare booked in Y, B, M, K, H, L, Q, T, N, R, or V class can upgrade into Z class (Business Class). For Air France-operated flights marketed by Delta, customers with a published fare booked in Y, B, M, H, Q, K, L, U, T, X or V class can upgrade into A class (Premium Economy) or Z class (Business Class). In addition, customers traveling on an Air France-marketed and operated flight and booked in W, S or A class as well as customers traveling on an Air France-operated, Delta-marketed flight and booked in P, A, or G class can upgrade to Z class (Business Class)"

NOTE: GUC usage on AF used to be restricted to high fare classes only. Phone agents may not be familiar with the new rules, and may need to be gently pointed in the direction of the DL T&C on their own website.

Using upgrades on Korean (restricted to certain fare classes only)

Dedicated thread: https://www.flyertalk.com/forum/delt...ed-thread.html

"Valid on Delta-marketed, Korean Air-operated flights for use globally on Delta's published fares booked in Y or B class to Korean Air's Z class, or booked in M class to Korean Air's O class."

GUC usage on Korean requires the purchase of high fare classes, which may mean that it is cheaper to buy a discounted business class ticket than to buy an eligible coach fare and try to upgrade. Uniquely, it is possible to use GUCs to upgrade from business to first on Korean, but only if you buy the most expensive business class fares.

Using upgrades on Aeromexico

"For travel on Aeromexico operated, Delta marketed flights this certificate may be used to upgrade on Delta`s published fares booked in W, Y, B, M, H, Q, K, L, U, T, X or V class and all fare classes upgrade into Aeromexico`s O class."

Also, will clear DM again after this trip about 3 1/2 weeks before LAX-AMS-CPT, flying on Thanksgiving day....think I'll be lucky on those KLM flights too??
You might have had better luck doing LAX-SAN-JFK or LAX-DTW-JFK. Just a thought.

The consensus seems to be that originating in Chicago for AMS-CPT is best.

I've done LAX-JFK-XXX with a GUC about 4 or 5 times and I've always cleared the TATL leg in advance and never cleared LAX-JFK before the gate (and once not even at the gate). I've also used an RUC on a JFK-LAX 6 or 7 times and I that has cleared in advance a couple times but mostly goes to gate (I don't usually use a GUC on the return)

Assuming one is going to Europe for vacation and not work, I think I'd rather fly out of one of the several other southern California airports, where upgrades (complimentary or via certificate) are more attainable, or at least route from LAX through say DTW.

Even better, pick up the TATL flight in PDX or SEA (or at most SLC) to maximize sleep/D1 time...SNA/LAX to PDX/SEA is just about a sure thing, and if not, who cares? GUC availability to LHR, AMS or CDG is plentiful from those ports...

Exactly. I don't think using a global upgrade certificate for BOS or JFK to LHR, AMS or CDG is worth it. It's such a short flight. I would want to at least maximize my value by getting the most time up-front as possible.

Well. I am 4.5 driving miles from door to T2, so LAX it is going to be.

Unfortunately, there are lots of destinations that I fly that are only served from JFK -- at least when I flew them: DUB, BRU, ZRH, PRG. And one time I did fly to LHR I routed to JFK so I could arrive at T3 as my traveling companion was flying VS and at that time only JFK and SEA arrived at T3 (and SEA arrived way too late)

Yes, I could double connect thru AMS/CDG but why? (except for the MQMS, maybe or reduced cost). I've been too chicken to try to use a GUC on the KLM LAX-AMS nonstop.

If I am flying to FRA usually try to connect in DTW (or ATL as second), unless the timing or price are better thru JFK.

And if I am flying so I have to double connect, LAX-SEA-AMS-XXX is my preferred choice if using a GUC with PDX/SLC second (have done all three the past 18 months).

I've really only missed two legs between LAX/JFK (one really doesn't count -- I was #2 for 0 two hours before the flight when it went MX and I was put on AF -- I literally was 10 seconds from hitting "request" on Lyft) This goes back to when we got Medallion upgrades on those routes -- I was 100% then.

KLM LAX-AMS always has space to confirm i find. I fly LAX-AMS-JNB because i know it's easy to confirm the GUC.

Its x2 daily on 747s.

+1 -- I find that LAX/SFO-AMS has lots of GUC space, and I haven't had to compromise on dates more than +/- one day. Even got SFO-AMS booking less than two weeks out, when you'd think they'd generally close off the Z fare bucket. My favorite use of GUCs is definitely J on the KLM 747/787 -- though my opinion may be slighly biased because my wife is quite fond of the little Delft houses...

Good to know -- having read all the travails of people trying to use GUCs on KLM I've just not had the mental effort to give it a try.

Given the poor showing they've put up so far on even identifying what the ticket is, it may be tricky to get that sorted out if that does happen.
Cautionary tale. For quick review, successfully applied GUC on VS...but did NOT receive mileage for the VS-operated flight without a fight. Here goes...

1) purchased T fare on Delta-marketed VS flight, and immediately applied GUC for UpperClass. Did everything with an agent in a single call.
2) when DL applied the GUC, it re-ticketed as a VS flight number.
3) for mileage earning purposes, original T fare lateraled into T on VS.
4) T on VS is not a revenue bucket. It's a straight up award bucket. I believe it is an economy award/companion ticket.
5) DL would not give me miles for the VS flight.

So, I was forced to make a handful of phone calls to sort out. I pointed out the obvious. For starters, I purchased a Delta-marketed flight. Second, nowhere (that I could find) in Delta T&Cs does it state that when applying a GUC, the Delta flight number drops and it assumes the Virgin flight number. Third, Delta T should not lateral into Virgin T since Virgin T isn't a revenue bucket in the first place.

Alas, I ultimately prevailed and collected my miles. But it was a pain. That said, agents were understanding and I felt they shared my frustration. No reasonable expectation that a passenger purchasing a mileage-earning fare from Delta would know that applying a GUC would render the earn ineligible.

A few things:
- HUGE congratulations into being able to use a GUC on a DL-marketed/VS-operated flight. I feel like you are the first (that I've seen) to be able to do this successfully.
- Sorry you had to jump through many hoops to collect the miles you were due. It seems like DL and VS still have to sort this out (though my sources tell me VS is moving to DL reservations systems, AIR4 as it's called, so perhaps this will sort itself out)
- Thank you for sharing your experience!

Congrats for having the patience to sort it all out!

That said . . . .

If what's posted in the "Story of the Day" comes true, I won't be posting in this thread for much longer.

Although, I do still have some Choice Benefits to claim, I hope we would be able to use them as Platinums once they're earned - if it comes to that!

VS moved to the DL systems a few months back.

Was able to use a GUC to upgrade a colleague on DL CDG-SEA this week. I was on a paid business class ticket, they were on an economy ticket. Their upgrade didn't clear in advance. Asked at check-in about upgrading since the waitlist didn't transfer over. They called the gate and ticketing. They said I'd need to pay the extra taxes for the upgrade (which I expected), and I'd need to do it at the gate. Went to the gate, inquired again. They were expecting us and made a few phone calls, took the credit card info and issued a new boarding pass.

Altogether, it took a lot of work for them to process the upgrade (quite a bit of time and many phone calls), but the AF agents were very helpful and provided excellent service during it all.
