Such as for CPU, it is the elite and 1 companion -- and need to be on just a two person PNR
For bags, boarding, security - yes

So one Global Services and two premier silvers on one pnr would be all treated as silvers for a cpu?

Split 4 PAX PNR for upgrades?
 
Hello -

Very out of date but both I and Ms. Pduck01 are 1Ks. If we have kids on our PNR to make it 4 PAX do we maximize upgrade odds with plus points if we split the PNR into 2 and 2?

Thank you!

Splitting the PNR would be necessary with respect to CPUs. With respect to Plus Points, I guess it would help, in case PZ turns non-zero but less than 4?

Another reason to proactively split PNR’s is to be eligible to “opt in” to Touchless ID. One downside of that is if one of the travelers has a BG1 due to status or seat location, upon splitting the now separated passengers will have potentially different BG#’s

As a solo traveler, I'm not too familiar.
Parents traveling ORD-SFO-HKG-SFO-ORD. 1K + member, no status
They both get upgraded at the gate for ORD-SFO and PNR is split. (I thought it was only split if one person is upgraded but the other isnt).

In the past, I recall if a reservation is split, the nonmember can no longer select e+ seats.
However, now, in the 1K member account, both PNRs are listed and e+ can be selected on both.
On the no status account, just one PNR is listed and e+ can be selected.
Did UA improve something?

The higher BG# person can usually board with the lower BG# person.

I'm flying with a group of six PAX originally on one PNR. One 1K, one gold, and four general.

The PNR was split with one group with two PAX, 1K and gold, and one group with four PAX, four general

On the two PAX PNR the flight status page no longer says CPU requested. Is this how the page display now? I could have sworn that it said CPU requested when I've done this before.

Goal is to only get two seats CPU'd.

Have a trip with parents:
  • Parents on a different tix
  • Outboud late Aug. No upgrades applied to their outbound segments.
  • Same TPAC flight on return (mid Sept) - that's the one I want to upgrade them on
  • Applied Plus Points to my own ticket and theirs too
  • I just got upgraded and they did not
  • Flight is currently P9/PN3/PZ0. Best I can tell PZ never opened
  • I called UA and was told they are #2 and #3 with about 24/60 booked; agent advised no further upgrades will be processed until gate (which I don't think is true) so no need to split

Should I split their PNR now and hope they upgraded at some point?

Splitting will increase the chance of clearing, but now you have a non-zero chance of getting only 1/2.

If you really want to split the PNR, do it but wait for a few days. The upgrade may be cleared soon.
Sound like SFO-PVG (if the agent gave the advice based upon his/her experience). :)

I’ve got an upcoming PNR w/ 3 pax seated in PP and using an instrument waitlisted to Polaris. Does anyone know if it’s standard United policy to skip over entire PNRs if the pax total is larger than the remaining seats (ie., 3 pax but 2 J remaining) or gate agents will split the reservation to accommodate the upgrades for 2/3?I keep getting mixed messages from United customer service on what will happen at T24.

At T-24, the reservation will be split and they will clear passengers individually.

That's if you check in at T-24h. Until you check in, nothing will happen, i.e. a 3-pax record with PZ2 inventory will block all waitlist clearance. (Note, that is waitlist clearance; new requests would clear.)

Interesting. I obviously know about PNR splitting with relation to CPU’s, but I never experienced an auto-split when using upgrade instruments for a multi pax PNR at check-in.

So you’re saying that if a multi pax PNR is not split by T24 (3 pax at the top with 2 seats, let’s say) it will freeze any upgrades on existing list? I’d like to assume that even with the split post check-in, pax retain their spot on the list if they were on the higher end because a companion with a higher status (that’s now on their own PNR).

Did something change recently? For a long time, UA wouldn’t auto-split for CPUs but would for instrument upgrades, on the assumption that you wouldn’t have listed the instrument unless you wanted the upgrade.

Correct. Usually priority is retained after the split, although I'm pretty sure I've seen cases (for other pax) of that not happening. I assume it's a bug when it doesn't happen.

It still auto-splits with instruments, but only after you check in.

meehgz Mar 20, 2025 7:21 am

Apologies if this has been covered - I searched a few keywords on this thread and couldn’t find an answer.

Upcoming short domestic flight in a few days, I’m GS and partner does not have status, currently on the same PNR. Our CPUs to F have already cleared. I may need to change my flight to later in the day, but my partner will keep the original flight that we’ve already been cleared on.

Is there a best time to split the PNR where he’ll be able to keep the upgrade that has cleared and not be downgraded?

I’m assuming I shouldn’t split now (although the fare difference for me to switch is small so that’s an option). Are the chances best for him keeping it if we’ve already checked in (ex at T-24, or a little later so I can SDC once split)? Or should I wait for that magic T-3hr period of years past (not sure if that logic still holds today) to split?

Hawkeyefan Mar 20, 2025 10:25 am

Got a 4 pass resi, I am the only one with status..Silver, msp-den route. 5 days out. F is wide open, not a soul in there as of today. Likely not an elite heavy route being non hub to hub. If I choose to split myself and one of my non status family members, what are the chances both of us get cpu'd on this one? Or safer just to split myself for better cpu chance? Flt 2041 on 3/26.

Should I split our party of four to two resi's now (me/Silver+non rev on one split) or just wait until check in? The same fare buckets as posted above are still intact.
Was unsure if I'd be considered for an earlier CPU if I had a non rev attached with me pre T-24? Maybe that rules me out prior to check in?

Aussienarelle Mar 23, 2025 8:25 pm

So my reservation is with non-staus pax. Outbound CPU waitlisted on a short flight (SAN-LAX) and PlusPoints came through for the outbound international leg. But for the return we have an instrument upgrade waitlisted for the international leg and CPU waitlisted for the short flight (SFO-SAN).

I have instructed my friend not to checkin online but wait until we get to the airport and check in together. This is because a few years ago when traveling with another friend IRROPS occurred and they lost the instrument upgrade as the reservation was split due to the waitlist for the CPUs.

My main concern is the upgrade request (and baggage allowance) for the return. Is the best advice to cancel the automatic CPU waitlist on the outbound before T-24? Same for the return if the upgrade has not happened before T-24 for the return date?

Edit: outbound donestic short leg is a B fare and I am 1K so maps into PN, not PZ. Return domestic leg is a W fare.

findark Mar 24, 2025 8:47 am

PNR split should keep the upgrade requests with priority; the main concern is that you can now clear one at a time if this is not a desirable outcome.

If you don't mind split clearance, I would let it split. While it's possible for that to cause a headache, 99% of the time it's fine.

I’m confused by your response. How do you have a non-rev as part of a paid reservation?

This happens in IRROPS but shouldn't otherwise. You shouldn't lose an upgrade that's already cleared, so your risk is on the return that somehow getting split screws things up for their priority.

You could make a gametime decision and see where you are on the list at T-4. But given it's SAN-LAX it may not be worth the CPU for the possible risk that results from splitting. But once you're in LAX no further splitting will occur until the final CPU leg (or before, but again, do you really care about LAX-SAN?) Bottom line is you want to make sure friend keeps your status for the return int'l leg IMO

Sorry non status I meant. Eddie fast fingers here.....

PATRLR Oct 10, 2025 3:44 pm

As I have said elsewhere, I'm a newly reminted 1K after a ~15 year hiatus. I vaguely recall when travelling with Mrs. PATRLR years ago PNR splitting causing us some headaches. I'd like to be sure I'm not about to get another headache...

Here is the situation:
  • Mrs PATRLR is a GM, I'm 1K. Flying tomorrow (so within T-24 and we have checked in) BDL-ORD and then ORD-MSY.
  • BDL-ORD, 1 J seat available and we are 1 and 2 on upgrade list using just CPU.
  • ORD-MSY, 1 J seat available, we were 3 & 4 with CPU. After check in, I applied Plus points. Now we are 1&2 on the upgrade list.
Our return flights are on a separate PNR

I assume at this point our PNR has been split, is that right? And from reading posts here, the risk might only be in the event of IRROPs. Is that right?

If just one of us gets upgraded BDL-ORD, will that have any affect on the ORD-MSY upgrades? I seem to recall years ago, single upgrade on first leg caused the GM to fall off the upgrade list on the second leg (or something like that).

And of course, what have I missed here, is there something else I should be aware of or concerned about in this situation?

Thanks in advance!

drewguy Oct 10, 2025 5:09 pm

The difference from years ago is that a PNR is split only if you get upgraded within 24 hours. Before that either you both are or both aren’t.

in theory your spouse should retain their position on the list, though that doesn’t always work. Sometimes they’ll fall to the bottom of the 1K list. Sometimes they might fall off (as GM) or to their status level.

if the return is a different PNR - do you book two one ways?

Yes, the return is on another PNR. ;)

KCRYSTAL Dec 13, 2025 3:39 pm

A few questions, please. Some map to question above, but not fully.
  1. One PNR with my 12-year-old daughter. I am 1K, she is a general member.
  2. (SEA-) IAH-EZE
  3. Upgrade for IAH-EZE waitlisted for both of us (with miles, for both PE and Polaris).
  4. Both PE and Polaris have at least 9 seats for sale (seatmap shows more, but that may be meaningless).
  5. We are in positions 2 and 3, and 10 and 11 on the waitlist for PE and Polaris, respectively. Hence mildly optimistic that PE may clear (Polaris will not, seatmap only shows 10 seats open)


We do want to (maybe have to?) sit in the same cabin.


  1. Will our PNR autosplit at T-24?
  2. If so, T-24 from the first flight. Correct?
  3. Will that bounce my daughter down the waitlist, or will the system keep us adjacent since she is a minor?
  4. Do I check in at T-24 from the first flight, or do it at the airport? Does check-in trigger a/the PNR split? If “yes”, then waiting for T-24 seems prudent.


Have been monitoring the flight for other days. United indeed wait with upgrades, even when PE and Polaris show *9.

So IF the system separates us, we will likely stay in E+.

Start a change flight process.
Select only the passengers you wish to break off to a new PNR.
Go thru selecting the new flights but do not confirm changes.
At this point you will find the PNR has been split.

Update: Some reports this no longer works

Just tried that, no luck. Went all the way to the "purchase" screen.
Call to 1k took care of it.

Im trying to do a 2x2 split with my party of 4 as well, keeping the same 2 legs on the same date. Cannot do this on ua.com, no option to just split without changing flights.
Regardless, if I have a rep do a 2x2 split, will I then be able to select Exit row E+ for two of us that are age 15+. Right now, one person in our party of four is 14 and I think that is why I cannot seat ANYONE in exit row E+, I am being blocked from selecting. Am I thinking correctly on this?

Honestly, if that exit row seating in the only reason why you want to split the PNR then I would first try and call in to see if an agent can assign 3 in exit row and then 1 elsewhere for the ineligible pax.

I hear you.
I ended up changing flights before dealing with any of this so now moot, but hopefully the dialogue was helpful to someone out there.

Yes...the beta in the app wont work when trying to link two award reservations. Hope that gets remedied.
