I sincerely doubt that there were ten other Silver passengers on your flight with a fare class of L. It’d shock me if there were three.

I suspect most of the people on the list behind you were non-revs.

I'm more concerned with the flight leaving on time given that 1/3 of the aircraft seats are unassigned (Econ Plus) and any sort of thing that goes marginally different than exactly as it should is a problem for the fine folks of G2 Services.

Yes, the computer doesn't account for oversales and just sees 3 seats remaining. For particularly severe oversales like this, it's not uncommon for someone in RM to go in and kick it at some point to reduce the oversale by running CPUs.

In terms of "too much to do before we push", I wouldn't even start thinking about it until T-3h or so and I would expect a decent bit of it to be resolved by then. At some point, putting people in E+ seats just happens fairly quickly.

IIRC, a lot of the BE seat assignments are done automatically. As in, a GA can just click something like "assign seats" and it will automatically do it for all BE passengers. I see it happen pretty regularly on my MSP-ORD flights that end up this way.

Lax-iad b789
 

Got the first big CPU clearance of the year on LAX-IAD (lie flat bed on B789). I killed CPUs on three short-hops (SFO-BUR, BUR-SFO and IAD-RIC) for this trip. IAD-SFO (CPU failed) arrived earlier and I got a successful standby for an earlier SFO-BUR, arrived at Burbank 2.5 hours earlier. Due to wildfire, I changed BUR-RIC to LAX-RIC. BUR-SFO was cancelled eventually and IAD-RIC arrived an hour later than scheduled. The decision for changing flights was the right one. But I wished that UA sent me the text (allowing for free change) earlier, not at midnight in my case. No waiver was posted before I went to sleep.

ORD-MTY - 1/16/25
T-52 as a UA Gold. Was J4 PZ3 at the time of clearing.
Fare: G ($85 airfare, $142 total with taxes)
Booked 12/24/24
SkyWest ERJ175 for ~4 hour flight

Nice! You should also have access to the UC in ORD as it should be "business class" - going to Mexico.

OP would have had access regardless, they're UA Gold (and *G).

Correct, I planned on going either way. Happy flying to everyone!

I didn't think this was the case. UA Gold (and G*) doesn't get you access to the UC unless it's a business class flight, correct?

For any international it does, even in economy. Canada and Mexico are included, too.

All non-UA *G have access for any *A trip and UA *G have access in an international itin, even in economy

Yesterday. UA193, GUM ROR MNL. I was on the 2nd leg, i.e. boarding at ROR, and pleasantly surprised to be CPUed as a lowly Gold. 1A and 1C were reserved for crew. 4D and 2C went out empty. At boarding, 1 GS and 14 1K boarded (or at least the GA let them board in those groups). Just thought it was odd...

Slow moving active military?

Seems odd, unless this was a glitch because it's a continuing flight with the same number. IIRC There used to be a bug in United's software that you could only be upgraded for both or neither leg if you were taking both flights - i.e., anyone doing both legs who wasn't upgraded on the first leg wouldn't end up on the 2nd leg upgrade list.

Apologies if this has been asked before, but I was not able to find anything via search. Are the CPU upgrade windows based on departure time (which I believe is how the United website reads) or some other arbitrary time like the upgrade list being publicly viewable? I ask because my travel on next Tuesday has had two legs upgraded at T-98.5 and T-101 hours (from departure) respectively. As a 1K this is before my understanding of my T-96 window opening. However, I'm a relatively new 1K and even as a 1K upgrades are not super common, especially well in advance of a flight.
