FEB 1, 2022 New GUC/RUC Inventory Rules
*****GUC*****
Flight has First Class
MC/C+ = Purchased
First = Last Seat J (Old Policy = OY)
Flight has DPS only
MC/C+ = Purchased
DPS = Last Seat (GUC=P / RUC=G) (Old Policy = RY)
Flight has D1 with no DPS
MC/C+ = Purchased
D1 = Z (Old Policy = OY)
Flight has D1 with DPS
MC/C+ = Purchased
DPS = Last Seat (GUC=P / RUC=G) (Old Policy = RY)
D1 = OY @ T-24h15m
Flight has D1 with DPS
DPS = Purchased
D1 = Z (Old Policy = OY)
Note: If GUC applied to domestic flight, it has better inventory than RUC (better chance for D1 transcon or to Hawaii)
*****RUC*****
Flight has First Class
MC/C+ = Purchased
First = Z (Old Policy = OY)
Flight has D1 with no DPS
MC/C+ = Purchased
D1 = OY (no change in old policy = OY)
New Delta.com Upgrade Availability Indicators that appeared 2/1/22 and what they mean
Dom D1 Tag meaning:
Global Upgrade Certificate Available = GUC in Z (OY = 0 for RUC)
Upgrade Certificate Available = GUC in Z /or/ RUC in OY both available
Dom F Tag meaning:
Global Upgrade Certificate Available = GUC in Last Seat J (Z = 0 for RUC)
Upgrade Certificate Available = GUC in last seat J /or/ RUC in Z both available

Apparently Delta is using public inventory buckets J Z P G (and non-public bucket OY in some cases) to determine GUC/RUC availability. However once they have confirmed you the system converts the segment in your reservation to a different bucket. Here is the class mapping:
GUC Usage
MC or C+ purchased / Upgrade to DPS / P class needed / Books into RV (Clears at T-24.15 into D1 as OX if OY available)
MC or C+ purchased / Upgrade to D1 (no DPS) / Z class needed / Books into OK
DPS purchased / Upgrade to D1 / Z class needed / Books into OK
MC or C+ purchased / Upgrade to FC (no D1/DPS) / J class needed / Books into OV
RUC Usage
MC or C+ purchased / Upgrade to DPS / G class needed / Books into RX (Clears at T-24.15 into D1 as OX if OY available)
MC or C+ purchased / Upgrade to D1 (no DPS) / OY class needed / Books into OX

More information and discussion about using same-day change after applying regional upgrades can be found in this thread: https://www.flyertalk.com/forum/delta-air-lines-skymiles/1709826-sdc-while-using-regional-upgrade-certificates-ruc-definitive-thread.html
While the RUC process is almost entirely opaque, there are a couple of "hints" of a correctly applied waitlist.
1a) When viewing a waitlisted segment on the DL.com web site (not the app), there may be two seat maps for the same flight. The first seat map shows the coach seat you are currently in, and the second seat map for the same flight says "you may not select seats for this flight" or something like that. This second seat map corresponds to a part of the waitlist process, and indicates that at least one step of the multi-step process to add an RUC waitlist was actually done. Unfortunately, this does NOT indicate that the other manual steps of the RUC waitlist process were successfully completed by the agent (i.e. even if you see the second seat map, there still could be something wrong. There is simply no way for the customer to tell.)
1b) The status for a waitlisted segment should say something like "Upgrade Waitlisted"
2) Assuming the waitlist does not clear prior to check-in, the second hint is the upgrade waitlist. If the RUC waitlist request was coded correctly, you should show up at or very near the top of the upgrade waitlist that you can see on DL.com or the app. If you find yourself at your "usual" spot on the upgrade waitlist, this is a clue that the RUC waitlist request was not coded correctly.
3) The RUC is a form of "payment". Until the RUC clears, it remains "unused" so a waitlisted RUC will still show in your wallet as "open".
You may also wish to peruse the wiki for the GUC success thread as some of the considerations/logistics are similar between RUCs and GUCs.

The clock begins ticking on RUC expiration when you make your choice benefit selection, so it's possible to time your selection when there is a specific need to use them.You can select your 2017 choice benefit as soon as DL recognizes your Plat status. Certificates expire 12 months from date of issue. 2019 choice benefits (earned based on how much one flew in 2018) must be selected by Jan 31, 2020.- If you select certificates as your choice benefit late in your Medallion tenure, it will still be valid after your status expires -- so for example if you earn Platinum Medallion in 2018, which is valid through Jan 31, 2020, but then only earn Silver Medallion in 2019, which becomes effective Feb 1, 2020 when your Platinum Medallion status expires, RUCs selected in January 2020 would be valid through January 2021 and could be used once you were only a Silver Medallion member, giving you a much higher upgrade list position on those flights where you attempt to use them.
- If you request to use a RUC on a flight and do not receive the upgrade, it is returned to your account for future use, but check your account to make sure.
- RUC may be redeemed for the named Medallion member and up to one travel companion traveling on the same flight (the companion officially no longer needs to be in the same reservation, though that rule was not actually enforced even when it was the official rule). The named member and the companion will each require a separate certificate.

Has Delta become less lenient about applying RUCs after expiration? In years past I've never had an issue applying a an RUC to a flight after the RUC expiration, even as far out as July, so long as the upgrade inventory was available. This year I have flights a few weeks after RUC expiration that have upgrade inventory but am getting a hard no on applying the soon to expire RUCs. I recognize in previous years I was very lucky; just curious if there has been a clamp down...

In my experience they have become much less lenient. There was a short flight on Xmas Eve with availability just after my RUC expired this year. I tried for 4 months once a week, to get it upgraded (I am stubborn), and could not win.

Had 4 RUCs expiring first week of February... was lamenting about not using them, then sent a tweet to @Delta For some help. Results:
Upgraded on ATL-CUN, but waitlisted on LGA-ATL
Cleared SAN-JFK in D1, waitlisted on JFK-SAN on a 737
Even if these are the only two that cleared, getting D1 for free makes RUC still my fav choice benefit.
What was really great about SAN-JFK is that my flight is a week after my RUC expires. I know it's been repeated on this thread before, but its good to know that if there's space available, you can use a RUC for a flight that occurs after the expiration date. Has anyone reported any issues with that? Because I'd gladly redeem my 2018 choice benefit to ensure I can keep my upgrade.

Looking for advice and whether I should HUCA for a fourth time. In my experience, when RUCs cannot clear at time of booking, the scenario listed at the top of the Wiki, is what I would see on delta.com. In this case, I am booking CVG-SJC RT. I have to connect, so after booking on delta.com, I called to apply the RUCs on the long haul segments only, as I do not want to burn them on the shorter connecting flights. After the first call, I did not see the Upgrade Waitlisted on My Trip details, nor do I see the dual seat map for the waitlisted segments. 2 additional calls to the Diamond desk, have resulted in the agents, emphatically stating the RUCs are correctly applied. They chuckled a bit when I made reference to this FlyerTalk thread.
"While the RUC process is almost entirely opaque, there are a couple of "hints" of a correctly applied waitlist.

There are clearly coding issues still in play with RUC's. I applied one for a trip from STL to SJU in mid January. It was waitlisted. The typical "Upgrade Status: Upgrade Waitlisted" wasn't showing up on either leg initially. I called twice, and both times they said it was showing up as waitlisted for both legs. Fast forward several days when I checked again. The STL to ATL leg is now showing waitlisted while the ATL to SJU leg continues to show nothing. Call DM line again. Nice lady says the coding on the ATL to SJU flight is coded as some sort of "emergency change" coding rather than what she normally sees for RUC's. She said it was not coded correctly. She puts me on hold for quite a while to work on it. She comes back saying that it's now coded correctly, but logging out and back in still shows no message about waitlist.
The takeaway is that even on this most recent call there is the prospect of incorrect coding as she said was the case. I'll be calling again shortly.

I was able to zero out my 3 remaining RUCs in the last three weeks.
Delta One JFK > SFO
Delta One LAS > JFK
Domestic 1st JFK > LAS
Was bummed that the flight I was on to Las Vegas did not have a Delta One cabin, as domestic first really isn't that much to write home about. Either way - content with the RUCs broadly and will just try to use them more aggressively next year on any delta one flight instead of trying to save them up.

Jfk- las d1
A JFK- LAS D1 cabin is showing wide open (all 16 seats), RUC is available, and only a handful of C+ seats taken. I'm debating using a RUC due to the possibility of a complimentary upgrade. How far in advance, does Delta usually sell the majority of their cabin for an early Thursday flight?

How much will it bother you when there's a week to go and it's dwindled down to F2 and you're sweating the upgrade?
It is true that RUC availability means RM does not currently forecast that they'll sell the last seat. RM is reasonably good at what they do. They're not perfect though, and even if there are 1/2 seats will you be first on the list? Will someone decide to take an FCM offer at OLCI? IRROPs accommodation from one of the non-D1 flights? Or maybe a new conference gets scheduled.
OTOH if you want to gamble on it, I guess you're going to the right destination

Or you can just wait until T-24, then see how many seats are still for sale/unclaimed, where you are on the upgrade list, and how many are below you, then decide whether to pull the RUC and see where you are on the Complimentary Upgrade list. Way too much stress for most, especially when you have so many RUCs available as a Choice Benefit!
