Guide to CPUs

In order for you to receive a CPU, four conditions have to be met at the same moment in time:

(NB: The following does not apply to GS members, whose CPUs process at least somewhat differently, out of the PN bucket.)

1. The flight must be within the relevant CPU window:
  • GS: 120 hours
  • 1K: 96 hours
  • Plat: 72 hours
  • Gold: 48 hours
  • Silver: 24 hours

If the flight is scheduled to depart after midnight central time, all of these windows open 24 hours early, due to a system glitch.

2. There must be CPU availability. CPUs for non-GS members draw from an invisible bucket that is often (but not always) pegged to roughly one or two less than the R bucket. At the gate, all remaining seats are released.

3. You must be high enough on the relevant upgrade list.

There are two separate upgrade lists, used during the two different upgrade processes described in (4) below. Understand how these lists work is one of the things people struggle with the most.

The Pre-Gate List (a/k/a the "sweeps list" or "EUA list")

This list is used in the pre-gate process described in (4) below. Your presence on the list is indicated by the CPU Requested icon/language on your reservation, but you cannot find out what position you are on this list through any public method. The list is sorted in this manner:
- Displaced first-class passengers (Bought two-segment F ticket, F wasn't available on this segment at time of purchase)

- GS using any method (note GS clear out of PN)

- Uncleared instant upgrades, sorted by fare class* and status (e.g.: Silver in Y, Plat in B, Gold in B, 1K in M)

- Waitlisted instrument/mile upgrades, sorted by status of redeeming account, fare class, and then time of request (e.g.: person in N upgrading using 1K's miles, Plat in S using own RPU applied on Tuesday, person in S using a Plat's RPU applied on Friday)**

- CPUs, sorted by status, fare class, and time of purchase (e.g.: 1K in E, 1K in N, Plat in E, Plat in X***, Gold in G purchased in November, Gold in G purchased in December)

*The coach fare classes, in the order that is relevant to this whole discussion, are: Y, B, M, E, U, H, Q, V, W, S, T, L, K, G, N, YN/HN/XN/X

**Note: The upgrades above CPU can clear using R space, CPU appears to be a subset, so R space alone is not sufficent for CPU clearing.

***CPUs are only available for mileage tickets for certain credit card holders. It's a complicated issue that is generally beyond the scope of this thread. There is a separate thread for it.
The Gate List (a/k/a the "visible list")

This list controls upgrades at the gate. It is semi-visible to the public on the status page for a flight, but the status page only shows checked in passengers. Even if you appear first on the list, you might actually be fifteenth by the time everyone checks in.

This list is in the same order as the list above, except that the time-related tiebreakers (such as time of purchase) are replaced with sequence number (which is related to time of check-in). Additionally, certain non-revs (airline employees and family traveling for free or at low cost) are put on the gate list, at the end.

4. One of the two upgrade processes must run.

The Pre-Gate Process (a/k/a the "sweeps" or "EUA")

This process runs at certain times in the days leading up to the flight. It typically runs at 24 hour intervals leading up to T-24, at which point it begins to run more often. It is unclear exactly how often it runs, or when it stops running. There are reports of upgrades that seem to have been given by the pre-gate system even once boarding has begun.

The Gate Process

This process is manually accomplished by the GA, typically once if there are empty seats after check-in has closed, and again if there are no-shows in F. In the latter case, the GA may come onto the plane to give the new boarding pass to the passenger.

Sometimes the GA might not run the process, which makes them a Very Bad GA. On very rare occasions, they might fiddle with the process to upgrade their friends, which we call "shenanigans." That makes them a Mega Bad And Very In Trouble GA. Both of these situations should be reported in the relevant FT thread and directly to UA.

CPU FAQ

I'm number one on the upgrade list on the flight status page. Does that mean I'm first in line for the upgrade?

No, unless the check-in window has passed and the flight is under gate control.

There are seats available in F, why have I not been upgraded yet?

That's not how it works. See above.

There is R availability, why haven't I been upgraded yet?

That's not how it works. See above.

Will the time that I check in affect my ability to get an upgrade?

Probably not. It is the third tie-breaker on the gate list only. See above.

Do I need to check in to get an upgrade?

No. Except at the gate. But if you're not checked in by that time, you have bigger problems.

Who are all these people on the standby list and the upgrade list(s)?

Non-revs. See above.

But the website says that the Silver window opens the day of departure, not at T-24!

Ignore that.

But the website says that there is a "transfer" of the lists at T-24!

Ignore that.

But the agent said ____________________________!

Ignore them.

This is a party of 2 itinerary... I'm 1K, but my friend is Plat. I am postulating that it would clear in the Plat window?

Starting taking screen shots of seat map at T-120. Started seating a few seats decrease in FC every 24 hours. Took screen shots. At T-24, checked in. Turned down $178 offer to switch to FC. No upgrade on checkin.

Checked award travel seats available on this flight using UA system. one seat available for miles in FC.

Checked seat assignment at T-20. MP screen shows upgrade confirmed for XXX-XXX leg, but not SNA-XXX leg. Never received email on upgrade.
Checked bag at SNA. Reprinted BP for leg 2 to get correct seat assignment in FC on BP.

FC cabin checking in full - 6 seats. No GS boarded (at least not when announcement was made for GS to board (SNA not fully using new boarding routine).

My take is fare class overrides 1K status for upgrades. Since Platinum was highest in CO (excl Pres Plat), this may reflect that in CO's view 1K=Platinum. And fare class beat status tier.

On notification: I've seen emails on CPU upgrades, and received them last year. The option on my profile is ON to receive these notifications. Not sending an email for leg #2 must be another 'glitch' in the system from UA's viewpoint.
I was there today and was #1 on the list, and yes that was the old process. G fare 2 weeks out.

So you were #1 on list - but did not get upgraded either?

I did not get upgraded. I was #1 on the list since the 24hr mark to the end (is that T-24, or is that 24 days?). I have a screenshot, but do not want to reveal to much.

Confirmed. Looks like lots of folks cleared the flight today at the 72 hour mark. I suspect there was some sort of issue...

Have a situation I haven't had before, so hoping someone has been here. Wife and I have a trip this weekend, booked on UA site. Outbound is all US-operated; on the return, the first flight is US-operated, and the final two are UA mainline. Looking at the seat map and fare class in expert mode, seems unlikely that upgrades on either of the UA segments will clear in advance.

Usually, if this is the case, I'll get asked at check in if we want to be added to the upgrade list (and split the record, of course). However, since US is operating the first flight, we'll be checking in with them. So presumably, won't be added to the upgrade list at check in.

Is there a way to get on the upgrade standby list at all (aside from hoping the staff at the connecting city can do it). I was thinking of just doing online check in with UA for their flights, but worried that splitting the record might muck up our ticket for the first US flight.

Any thoughts, experience or insight?

MCI-DEN 1-18-13 9:52 am

1K here on W fare and T-96 came and went with R space available. T-24 R1 RN 1 but no CPU. Used OLCI and offered UG for $159 with one seat in F showing. Declined.

UG Waitlist shows me #1 with 5 of 6 F seats booked. Waitlist grows to 9 people and now F shows booked full with the SAME 9 people still showing on F waitlist at T-9.

If I can get a CPU on a midmorning, midweek MCI-DEN on a W fare, what route can I get one on?? I find it extremely hard to believe that someone bought a first class ticket tonight at T-9 when there are two cheap Y fares to be had. SDC hasnt kicked in yet for misconnects etc thru MCI, so that cant be it.

My issue is with the "perk" that I have as a 1K of being upgraded at T-96. What value does this perk have if they never release any seats at T-96 for CPUs for 1ks? I regularly sit and watch R inventory disappear from T-96 until boarding without a CPU clearing. Thats fine if they want to sell those seats but UA should CLEARLY state that all F seats will be offered for sale until T-1 and then CPUs granted based on x,y,z. Whats the point in leading us on with the T-96 nonsense if the inventory specialists are evaluating each flight and then releasing F seats based on how they're selling in real-time? Just tell us that "if they're available, you might get one based on xyz". I could live with thta but seeing availabilty at T-96 and not getting the CPU (to then watch the availabilty drop each day)really has a negative impact on me.

Maybe try flying SAN-MMH on a CR7? Usually everyone clears that upgrade since the flight usually only has like 2-4 people on it a day.

But I agree with your points. Upgrades have become increasingly harder and harder. As a 1K my upgrade chances are slim now too (route dependent) compared to when I was a 1P with PMUA and used to clear a lot of upgrades.

I see the system is still horribly broken.

Two 1Ks on the same PNR from SFO to LAX tomorrow. Despite 9-open seats 4-days out, upgrades did not clear at the 1K window. System showed RN0 R0.

Started showing RN8 R8 in the past 18-hours, but sweep has not occurred so upgrades still haven't cleared. In the interim, other elite passengers have apparently booked tickets and immediately cleared into F.

There are now three open seats spread throughout the cabin. So if we clear, we won't be sitting together without seat juggling on board.

Thanks United.

Sorry, but what's horribly broken is your understanding of the CPU processing system. Unlike PMUA where NF>0 meant a UDU would clear, that is no longer the case under the new United with R>0.

My understanding that R>0 and I don't clear because there has not been a sweep, but someone with lower status who books before the sweep occurs will clear before I do, is incorrect?

So I take it the upgrade system is not horribly broken? (As we sit at #1 and 2 on the upgrade list with one seat now available.)

R space is for GPU, RPU & miles and not CPU. There is no visible inventory for CPU (unlikely NF in PMUA days). Additional the inventory of YBM instant upgrades and buy-ups (PN) is linked, and a used PN space is likely to reduce R space. So there can be lots of upgrade space (R/PN) and none for CPUs.

It is true CPU is done by sweeps but you can not see the inventory (isn't R). UA goal is to fill F as much as possible without CPU such as with late purchasers of YBM fares.

Thanks.

There was NEVER--not once--that I didn't clear into F on an SFO-LAX leg in pre-UA days.

And UA wonders why I have shifted almost all of my international travel to foreign carriers? (Nah, I know UA doesn't care.)

Agreed! Haven't not cleared a simple SFO-LAX flight since I was maybe a 1P. So far this year out of 4 MRs I've seen more of coach than I have first. Kudos if UA can get a few quick bucks from infrequent UA flyers, but they have yet yo realize what it's done to their loyal flyers. I just don't understand why someone hasn't crunched the numbers and informed management about the attrition.
