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?

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.

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.....

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!

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. ;)

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+.

Do I need to call 1K line to split a reservation? What are the detailed steps if I can do it myself on website or App?
Thanks.

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.
