Types of Upgrades
UA's Upgrades overview
UA has multiple methods for upgrading to a higher cabin. Examples include: Economy to Domestic First, Economy to International Business or Business (ex-p.s. flights) or Economy to Premium Economy ("Premium Plus").
In this regard, seating in Economy Plus is considered Economy.
Not all upgrade methods are available on all flights (see table).
Paid/cash upgrades are a different mechanism and are only available if confirmable -- no waitlisting. Depending on methods, paid upgrades can clear into almost any fare class. If the class would otherwise be used for upgrades, the cash upsell can show up on the cleared upgrade list.
Plus Points and MUA (also called "miles+cash upgrades") are collectively referred to as instrument-supported upgrades, as they are considered with equal priority once applied. They may also be used on Copa (CM), Lufthansa (LH), and ANA (NH) flights.
Waitlisting for a premium cabin award and all forms of Economy Plus are not considered upgrades.
Upgrade Priority and Required Inventory
All upgrades other than CPU may clear immediately if the required inventory class is available. If you request an upgrade when there is not inventory to confirm your upgrade immediately, you will be added to the upgrade waitlist. The required inventory classes are as follows:
RN class is required for all upgrades to Premium Economy (United Premium Plus)
PN class is required for Instant Upgrades to Business/First from Y, B, and M fares for Premier 1K members, and for all upgrades to Business/First of any type for Global Services members.
PZ class is required for all other upgrades to Business/First except CPUs.
Note: The display of the upgrade lists is rather complicated at the moment. There seems to be more information available than usual, but its accuracy is disputed. The following is how it has historically functioned in terms of public visibility.
Passengers with unconfirmed upgrade requests will be added to the upgrade waitlist. This is not the same as the upgrade standby list which you can see on the Flight Status page. You cannot see this list by any means. The ordering of the upgrade waitlist is as follows:
Recent announced modification
United will periodically run sweeps from this list. The required inventory class for your upgrade does not need to be available in order to be upgraded from the standby list; passengers on the list will be upgraded at the discretion of United's systems. (You can also think of it as space was opened and then you immediately took it.)
Once check-in starts a new waitlist will be generated for use at the gate. The pre-gate list will continue to process until the flight goes to the gate, typically one to three hours prior to departure. This new list is the visible one on the Flight Status page. Generally they will have the same order, but there can be some differences in priority ordering of the two lists -- usually due to the time tiebreaker -- which is time of request for the pre-gate list and time of check-in (sequence number) for gate list. The visible (upgrade standby) list has only checked-in passengers and is not used until the flight is under gate control and the gate agent manually processes an upgrade.
The upgrade list sometimes also shows passengers who have been upgraded. Advance-cleared upgrades will not show on the gate list as cleared -- only passengers who clear after they check in will display with a green checkmark. Some paid Premium Economy fares may show as a confirmed upgrade to Premium Economy.
For both cases, display cleared upgrades will appear in alphabetic order and regardless if checked-in (as long as a seat has been assigned). Uncleared, waitlisted requests will appear, once checked in, in priority order. But until all have checked in, the visible gate waitlist is incomplete.
Upgrades and Companions
Main article: Comprehensive Companion Upgrade Questions
The following applies ONLY to the invisible upgrade list.
Up to one companion on the same PNR as you is entitled to a CPU based on your status. However, because PNRs must consist only of passengers with the same itinerary, you will only be eligible for an upgrade if all passengers on your PNR have the same upgrade eligibility. For CPUs, you may extend your CPU status to one companion, and then the system will take the status of the lowest passenger on the reservation.
This is a little complicated. Here are some example PNRs:
1K and non-status companion: both are eligible to CPU as 1Ks
1K and two non-status companions: no one is eligible to CPU
1K, Gold, and non-status companion: the companion gets "1K CPU status" but the Gold cannot, so all three pax have Gold priority
The situation for instrument supported upgrades is slightly different. Waitlisting an instrument is also all-or-nothing on the PNR. Either all pax must have a waitlisted upgrade, or none may. If you have a waitlisted upgrade for a multiple passenger PNR, it will have the priority of the highest Premier status on the reservation. Thus:
1K and non-status companion, 2x GPU applied: both are eligible as 1Ks with GPU
1K and three non-status companions, 4x GPU applied: all four are eligible as 1Ks with GPU
Multi-pax PNR upgrades are all or nothing - you may (or may not) be skipped over if there are fewer available seats than members in your party. If you do not like the treatment of your PNR, you may split it into smaller pieces at any time and be treated as smaller groups or individuals.
Now, what happens if you haven't cleared by check-in?
Multiple pax PNRs are not eligible for the (visible) upgrade standby list. If you wish to be added to the list, you must split the PNR at check-in. This often happens even if you didn't intend to. Note, however, that the hidden list is active until 3 hours before departure and splitting your PNR changes it. Therefore, you may wish to delay check-in until the airport. On the other hand, the tiebreak for the gate list is time of check-in, so you may wish to do so immediately. It depends on your situation.
Companions may be eligible for the upgrade standby list even after splitting the PNR, if it is split at check-in. The behavior of your companion(s) depends on whether the reservation had instruments applied. You may have one CPU companion, who will be waitlisted with your Premier priority but with an effective fare class below X (namely, last). If your companion was on a different PNR originally, or you want to designate a different companion, an airport agent can do that for you. Therefore, the list of 1Ks might be:
1) 1K on an S fare (you)
2) 1K on a K fare
3) Your no-status companion
4) Plat on a B fare
If your reservation had instruments applied, however, this process is different. In this case, if the reservation is auto-split at check-in, all travelers will have your Premier priority with their fare class. Say you are a 1K with three non-status companions, all with GPUs applied. Then you have
1) 1K on a V fare, GPU applied
2..5) you (1K) and your three companions on W fares, ordered by sequence number
6) Plat on a Q fare, miles+cash applied
Frequently Asked Questions
I was #1 on the upgrade list, but someone else got the upgrade instead. What happened?
The most likely answer is that the upgraded passenger was not checked in. Remember that the upgrade standby list (the visible list) only shows passengers who have checked in.
I'm #1 on the upgrade list but seats in the forward cabin keep disappearing. No one is being upgraded. What's going on?
There are two major sources of this. First, once your flight is within 24 hours of departure, it is eligible for SDC. Passengers with paid premium tickets can change to your flight and take seats. Many experienced flyers, especially FT members, underestimate the volatility of flight loads on the day of departure. Additionally, United usually makes a time-of-departure upsell offer available at check-in. Purchasers of this upgrade may often appear similar to last-minute revenue bookings.
I was waitlisted for I (or IN) class and did not clear. Am I now eligible for an upgrade?
"Upgrade" is the wrong terminology. You should be automatically placed on the standy list for business or first (whichever applies). Historically there have been problems with this occurring automatically, but that seems to have mostly been fixed. The exact priority compared to passengers who are waitlisted for an upgrade is unclear and a matter of some dispute. See discussion of GG ONESTANDBY lines 32-55.
Who are these people who are on standby lists for both Business and First?
These are non-revs (i.e., UA employees and family members) - either NRPS (non-rev positive space) or NRSA (non-rev standby). Non-revs can list for any cabin. NRPS are traveling on company business (e.g., deadheading pilots) and will clear into open space ahead of upgraders. NRSA travel standby and will be last in priority after all paid passengers. Why would someone be listed on both standby & upgrade list(s)?
Can you have one companion on a different PNR?
Yes, but only at the airport/gate and some agents are not familiar with the process. They are at the bottom of your status group.

UA's Upgrades overview
UA has multiple methods for upgrading to a higher cabin. Examples include: Economy to Domestic First, Economy to International Business or Business (ex-p.s. flights) or Economy to Premium Economy ("Premium Plus").
In this regard, seating in Economy Plus is considered Economy.
Not all upgrade methods are available on all flights (see table).
- Complimentary Premier Upgrades (CPU) are available for most North American flights, Central America flights, and some select Oceania flights.
"ex-PS" flights (EWR-SFO/LAX, BOS-SFO and v.v.) and Hawaii-EWR, IAD, ORD, IAH, DEN, GUM, MAJ and v.v. are not CPU eligible. CPUs are available for all paid fares and in some cases on award tickets with certain credit cards. A CPU is requested automatically for all elites as long as there is a maximum of one non-Premier as only one companion on the same PNR is also eligible for CPU. CPUs cannot be confirmed until inside the particular window:Global Services: 120 hours
Premier 1K: 96 hours
Premier Platinum: 72 hours
Premier Gold: 48 hours
Premier Silver: 24 hours- Plus Points (provided to Plats and above) are the upgrade currency of United elites. This wiki of this thread has more details about pricing of various Plus Points upgrades.
- Mileage Upgrade Awards (MUA) can be requested for all UA flights with a higher cabin on all paid fares. This a varying amount of miles and a $ copay (elites are exempt from the co-pay for CPU eligible flights) -- see UA award chart for details Note the miles and copay are due at time of the request and will be returned if unsuccessful.
- Instant Upgrades are space available for all elites on Y & B fares for CPU-eligible flights at booking. For Plats and below these require PZ space. For 1Ks and GS, this can be done on Y, B & M fares and requires PN space. 1K & GS, if not cleared at booking, will be waitlisted.
- Plus Points (provided to Plats and above) are the upgrade currency of United elites. This wiki of this thread has more details about pricing of various Plus Points upgrades.
Paid/cash upgrades are a different mechanism and are only available if confirmable -- no waitlisting. Depending on methods, paid upgrades can clear into almost any fare class. If the class would otherwise be used for upgrades, the cash upsell can show up on the cleared upgrade list.

Passengers with unconfirmed upgrade requests will be added to the upgrade waitlist. This is not the same as the upgrade standby list which you can see on the Flight Status page. You cannot see this list by any means. The ordering of the upgrade waitlist is as follows:
- All Global Services members (presumably prioritized similar to other members below), including those awaiting a CPU.
- For CPU eligible flights, Premier 1K members on eligible Y-, B- and M-class fares that were not cleared at time of booking are prioritized by fare class and then time of request.
- All travelers on waitlisted instrument-supported upgrades: Prioritized by Premier status of the traveler, then fare class and then time of request. There is no priority difference between types of instruments.
- For CPU eligible flights all remaining Premier members: Prioritized by Premier status of the traveler and fare class (award tickets are considered the lowest fare class)
Recent announced modification
Effective August 14, 2018, upgrade waitlists are processed in the following priority order:
- Premier status of the traveler
- Fare class
- Chase United MileagePlus Club cardholder
- United Corporate Preferred participant
- Time of request
Once check-in starts a new waitlist will be generated for use at the gate. The pre-gate list will continue to process until the flight goes to the gate, typically one to three hours prior to departure. This new list is the visible one on the Flight Status page.

Neither. It just means that there aren’t currently any upgrade seats available. They may open; they may not.
1K GPUs clear into R, regardless of the underlying fare class. If you’re booked on the same reservation, you’ll need R2 before you’ll be able to clear. An M fare is a high fare class, so you should be near the top of the waiting list among people using 1K instruments. However, you’d still be behind anyone using instruments from a Global Services member.
Good luck. ^

So, yes, for the best chance of clearing at least one upgrade, split the reservation and watch for R to show up, because they don’t always clear the upgrade list promptly anyway.

Yes, although if you're already waitlisted it can be a real hassle, since most agents will now refuse to clear it, requiring that you pull the instrument and apply it yourself.

Can't figure this out. On the buy-up CPU list, I am #1 , but on the gate upgrade list, I am #2 and #1 on that list is #5 on the buy-up CPU list. What could be the reason for this? And would this mean that if the pre-gate CPU sweep happens, I would get a seat if available, but at the gate, I would lose out to #5 on the buy-up CPU list?

I believe that buyup list is the CPU list, and doesn't reflect instrument supported upgrades.

Is it true that since last month, holding the United Explorer Club card will get you higher position on the upgrade list? It says so on the UA website:
https://www.united.com/web/en-US/content/mileageplus/awards/upgrade/default.aspx#cpriority
that after status and fare class, being a club card holder is the next criteria to break ties.
(from what I remember it used to be just time of request -- so, for example, getting all my upgrade requests in super early put me ahead of other 1ks upgrading W fares with GPUs - now I'd be behind any 1ks who have the club card, even if they put in the request half a year after I do)
Would this also apply to the business version of the UA club card? I'm wondering whether I should get it again (I used to have the card but felt $450 was a bit steep for how little I used it)

Effective August 14, 2018, upgrade waitlists are processed in the following priority order:
- Premier status of the traveler
- Fare class
- Chase United MileagePlus Club cardholder
- United Corporate Preferred participant
- Time of request
It's a MP branded card

totally don't understand how this thing works.
SFO to HNL, everyone on same fare
Mom - GS didn't use any supporting instruments on CPU.
ME - GS used a GPU to be waitlisted
Dad - 1k used a RPU to be waitlisted.
Mom got upgraded first as CPU before my GPU.
Called GS, GS was confused and escalated to headquarters. They are confused as well.

(PN always open at least as early as R does, so inside GS CPU window, CPU can clear before non-GS certificate will).
