I connected via ORD to MKE but my bag didn't make it. Next flight is 6+hrs later. I was driving pretty far away where GRB would be closer and the person filling out the claim said he would tell them to put it on a flight to GRB as it's an earlier flight and shorter drive. I received the claim and see it in the delivery notes. However I wondered if anyone would actually proactively read it or only once it arrives. Similar to PNR notes
Anyways my bag didn't make it in the GRB flight
Maybe I should have asked him to pickup the phone and call the ord baggage office

Yes, they do read the notes, or figure out which airport is the closest... eventually. Misconnected bags are often processed overnight.

I had a bag where it was misconnected and was intended for EWR. Whoever saw the Connecticut delivery address put it on 2 more flights - EWR-IAD-BDL, and have BDL agent to arrange the delivery.

OK, I wasnt sure how someone at ORD would know to pull up my claim and look at it. At least prior to the flight it was leaving on.

anyways, in my case, it didn't make it on the earlier flight. Maybe they felt it wasnt worth the trouble for me to get it earlier.
The agent said there is a pickup (for the company that delivers bags) at 5pm and 10pm. Bag was just unloaded at 4:55pm

Also, the note just says "fwd to GRB and deliver" so I hope they don't now interpret it as, send it to GRB and have them deliver it vs go direct.

I believe they are going to look at your delivery address and route it the best way to get it there - closer airport if that is the easiest. Might not always be.

Your bag not making it on the next GRB flight doesn't mean much - bags of pax traveling on that flight are going to have priority and their might have been no room. I had a bag delayed into CUN, day after Crowsstrike bug, and bag tracker was showing it was going to be on about 4 different flights to get it to CUN later same day. I watched my AirTag track the bag between the different gates those flights were leaving from, never to actually leave SFO (went between T3 and 2 about 3 times). Ended up eventually making the same flight next day, not any of the 4 previous flights (combo of non-stop and connections) it was apparently slated for.

Another time, we flew to SIN, and were flying on a separate ticket to BLR on SQ about 20 hours later. We gave the India delivery address since we knew it wouldn't make it to SIN in time...I'm not sure what routing it took (this was AC, that time), but it was delivered within about 12 hours of our arrival time. Clearly the system worked to route it onto a flight to efficiently deliver to BLR - I was surprised at how quickly it showed up given the circumstances.

My most recent experience: Was flying IAD-BTV, and my bag was left off the flight. UA put it on the next nonstop (rather than any of the connecting options, which would get it in ~4 hours earlier), and that nonstop would get it into BTV too late for it to do me any good--so I asked they deliver it to my home address.

This should have resulted in the bag being pulled at IAD sometime during the next 8 hours and handed off to the delivery service. Instead, it still got put on the evening IAD-BTV flight. At BTV, I tried to explain this to the UA agents, and asked that if possible, they put it on the BTV-IAD 7:39pm flight, as then we could just skip delivery altogether, and we could retrieve it at baggage claim at IAD. The agent never really understood; she did say she saw the delivery request in the system, and couldn't understand why the bag had been put on the flight to BTV to begin with. "You want it to go to Virginia, right? I'll radio the ramp and ask them to update the tag and have it sent back to IAD, but I'm not 100% it will make the flight." Fine, I said; if it went out on the early-a.m. flight BTV-IAD today, no big deal; I could wait for the delivery service.

So... the bag didn't make the flight last night. It went on the early morning BTV-IAD today. But... then UA put it back on the morning IAD-BTV, and as of right now, it's back in BTV yet again. Which is complete SMH for me; it's like literally no one has looked at the baggage notes. Meanwhile, UA emails me that they are "still trying to locate my bag." LOL; from the scans, they should know exactly where it is.

Eventually, I expect it will show up on my doorstep, but it wouldn't surprise me to see it do another round trip or two before someone at either IAD or BTV figures things out. Meanwhile, I bought a cheap bag at Walmart to carry the stuff I need to get back to IAD to begin with, and will submit the receipt over to UA to reimburse.

Exactly my experience. It's like the people doing the routing aren't reading the notes at all or, even worse, can't comprehend them. UA's baggage recovery system is a mess.

I flew UAA927, barely made this flight because my connecting flight from Italy was 90 minutes late.

But my checked bag didn't make it.

Now the United app shows it was delayed but last night at SFO it didn't show that.

My question is, would UA or LH put that bag on the first UA fligh from FRA to SFO which would be UA59 or wait until the later UA927 flight since that was the one I was booked on?

Google shows a UA8829 but I'm assuming that's an LH flight and UA codeshare.

In any event, both UA59 and UA927 are en route, but both departed late so I'm guessing they might not deliver my bag tonight.

Absent other issues (like weight restrictions), UA will put the bag on the next available flight to get it to its destination. It doesn't have to go on the same flight # it was originally supposed to travel on.

In fact, I think someone at BTV screwed that up and redirected my bag onto the same flight # it was originally on... adding an extra round trip. Supposedly it will be delivered today (and I got a $150 travel credit when I filed a claim for $58 in incidentals to be reimbursed). We'll see.

Just checked the AirTag on the checked bag and it shows it's in SFO. So either it came with UA8829, landed at 12.37 PM PST, or UA59, landed at 4:03 PM PST. UA927 is en route and not expected to land until after 8 PM.

It's showing in Terminal G as opposed to near the gate where the aircraft arrived at so hopefully that means it's with the baggage people.

My question is who is looking at this and when.
This is how I imagine it to work.

1. When my bag fails to make it onto the flight for whatever reason, it makes sense for them to just put it on the next flight to the same destination. They don't know where my hotel is going to be.
2. I inform baggage claim about where my final destination is and he creates a ticket putting a note to put it on the GRB flight.
3. Once the ticket is created, when is the next time someone would look at this ticket? Is there someone at the airport that is just constantly reviewing all tickets and reading the notes inside? Seems unlikely. Maybe someone is getting notified of all NEW tickets, that might be more likely. That was my question
4. So ​I assume the next time the ticket is looked at is when the bag is left on the belt and someone from the baggage office is forced to lookup what's going on with the bag. At that point it is obviously too late.

Maybe the GRB flight couldn't fit my bag. And nothing reflected in the status. That's always a possibility.
Anyways, the bag made it at 4:55pm. There is a pickup time at noon, 5pm and 10pm. I called the line shortly after that arrival and asked them to call the baggage desk but there was no answer ofcourse. The person on the line told it would be on the 10pm and I'd be getting it late at night. It did not get picked up til noon the next day (after I called again and someone finally picked up at the baggage desk). I made sure to time my call shortly after an arrival. I eventually asked them to remove the GRB note from my ticket, because everytime I called in, they thought that I wanted the bag delivered to GRB. The delivery company delayed my delivery because I was so far and I didn't receive it til 8pm. I did quickly get approved for inteirm expenses and also got a voucher.
I wonder why my bag didn't make the flight in the first place. I had a 90min connection. The plane was swapped from the typical CRJ to an E75. Unfortunately this isn't the first time this has happened on this route. In the past there was a flight about an hour later so I just waited.
