This wiki was created to distill SDC (and related standby) down to a set of rules in the hopes of benefiting others.
The official "rules" can be found here. In practice, some of the rules almost always apply, and some are more flexible.
Note there have been reports of SDC to one segment removing confirmed CPU upgrades on downline segments. If maintaining the confirmed upgrade is important then these changes should be handled with care.
Most Frequently Asked Question: When do I call/go online to make the change?
Follow this flowchart:
Question 1: Are you within 24 hours of your currently scheduled UA(*) operated flight that you're trying to change off of? If yes, continue to Question 2. If no, continue to answer 1.
Question 2: Are you within 24 hours of the first UA operated flight you're trying to change on to? If yes, continue to to Answer 2. If no, continue to Answer 1.
Answer 1: No, you cannot call/go online yet to make an SDC.
Answer 2: Yes, then you can call/go online to make an SDC.
General Baseline Rules
These are the general rules that usually apply to SDC's; falling outside these rules usually requires payment of a full change fee and the fare difference:
How to SDC
SDC can be accomplished in a few different places (in rough order of likelihood of being able to get the rules bent):
Please note that the United.com “change flight” link before checking in within T-24, is broken. The website may not show all available options and will often attempt to collect the change fee rather than the SDC fee (if any).
NB: An SDC where the original itinerary (in one direction) has three or more segments cannot be done online.
Nuances and Loose Rules
Now for the hard part: figuring out where the flexibility is in the rules. This list is compiled from the responses to people saying "Can I do X?" where X is something that is not clearly permitted by the rules. One's likelihood of success here depends a bit on the method used for the SDC.
For each item, the following codes apply:
Y = officially permitted and possible using any method
A = not permitted but perhaps possible using an agent (phone/counter), perhaps having to HUACA
A* = mixed reports of success with an agent (phone/counter),
N* = possible only if you find a very accommodating agent
N = little or no reported success.
If you encounter issues with an agent (phone or counter/gate), you can ask the agent to reference GG SDC. Additionally, GG SDC line 61 specifically references that fare classes are supposed to level out 3.5 hours before departure, so you might be able to use that to your advantage if fare classes have not leveled out and you're trying to ask an agent to open up the correct inventory or force you onto the flight.
Note -- as of 11/27/2017: A datapoint indicates that UA may have updated its GG rule regarding leveling out to state the following:
Standby
You may stand by if seats are not available in the purchased fare class. In these cases, the same-day change fee will apply, but will not be charged unless you are assigned a seat on your alternate flight. Changes in routing are not allowed when standing by. Standby may be requested on the day of departure at an airport kiosk or with a United representative at the airport. Once you are added to the flight standby list, you can check your real-time standby status at united.com/flightstatus or on your mobile device at mobile.united.com/info.
Instead of paying a same-day change discounted fee, can I stand by for my desired flight for free?
No. The only time you may standby for free is when the fare does not have any penalties for making changes, or when standing by involuntarily due to a flight irregularity.
Can I pay the same-day change discount fee with cash?
Cash will only be accepted by a United airport representative when the change is available to be confirmed, not for standby travel.

General Baseline Rules
These are the general rules that usually apply to SDC's; falling outside these rules usually requires payment of a full change fee and the fare difference:
- The departure time of the first segment of the old itinerary and the departure time of the first segment of the new itinerary must both be within 24 hours of the moment that the change is made.
- Only applies to UA/UX operated flights, domestic or international. Changing from a non-UA operated to UA operated may be possible.
- The ultimate origin and destination airports must remain the same.
- Routing can be changed (addition, deletion, or change of connection points) but the routing rules of the original fare usually apply.
- All remaining unflown segments in single fared itinerary are considered together (i.e., if you're flying WWW-XXX-YYY-ZZZ, you can go to a kiosk at XXX and potentially fly XXX-AAA-ZZZ or XXX-ZZZ direct).
- SDC can be done an unlimited number of times, and can therefore be used to extend a trip indefinitely (pending availability).
- SDC costs $75 for Members and Silvers - the fee is waived for Golds and up (plus any applicable fare difference, see below). *G's may also get free SDC, although there is no mention of this in the official rules. Once in-route, fees for an earlier connecting flight may be waived per GG SDC Line 118.
- Non-elites on the same PNR benefit from any waived fees for SDC.
- No fare difference is charged so long as there is availability on all of the new segments in the originally ticketed fare class. Fare class availability in all classes often opens up after T-24 and almost always opens up at T-3 unless the plane is very full.
- SDC on bulk tickets, including United Specials, is not permitted.
- SDC is permitted on both domestic and international itineraries.
How to SDC
SDC can be accomplished in a few different places (in rough order of likelihood of being able to get the rules bent):
- United mobile app
- Kiosk
- Phone
- On united.com, right now only the "Search Other Flight Options" button during On-Line Check-In (OLCI) works. This has spotty availability, particularly if the change would involve paying an additional fare due to fare bucket non-availability.
- Counter/Gate (although reports are that most airport agents are not familiar with the SDC policy and may not allow you to SDC to a valid itinerary--you can try to direct them to look up GG SDC, but they often won't understand that what you're trying to do is permitted by those rules)
NB: An SDC where the original itinerary (in one direction) has three or more segments cannot be done online.

N = little or no reported success.
- Violating various non-routing fare rules (day/time, minimum stay, etc.): Y
- Change destination to ultra-close airport (see the old S*FAR/STANDBY): A
- Change destination to a co-terminal: N*
- Change destination to an entirely different place: N
- Change itinerary at the beginning to include illegal layovers (> 4 hours): N*
- Change itinerary at the layover point (using kiosk, app, or agent) to create an otherwise illegal layover: Y
- Change itinerary at the beginning to add a layover point not permitted by the routing rules: N*
- Change itinerary at a layover point to add another layover not permitted (either in terms of number of segments or routing rules) by the routing rules: Y
- Change to a flight exactly 24 hours before or after the original flight: N*
- Change to a flight exactly 24 hours before the original flight, if the previous day's flight has been delayed: Y (based on one report)
- Combining separately-fared segments to do SDC (e.g. XXX-YYY+YYY-ZZZ -> XXX-ZZZ): A
- Change UA-codeshare, non-UA-metal segment to UA metal: A
- Change from UA metal to UA-codeshare, non-UA-metal segment: N (see post 1813 for one exception)
- Change from UA-codeshare, non-UA-metal segment to a different UA-codeshare, non-UA-metal segment: ??
- Change on a non-UA ticketed segment: N* (with potential dire consequences)
- Change from an upgraded flight into Y on the new flight: Y
- Change from a GPU-upgraded flight into J/F on the new flight: A
- Change from a CPU-upgraded flight and get confirmed into available R space on the new flight: N*
- Change from an instrument-upgraded flight and get confirmed into available R space on the new flight: A*
- Non-elite on different PNR benefiting from Elite's waived-fee SDC: A
- Change at origin airport after tendering a checked bag: N
- Change at layover airport when a bag has been checked: N

I’ve found that they don’t always seem to honor this unless Y is large. And, even then, it’s only really valuable for nonstop travel. If you’re connecting, there’s no guarantee they’ll have opened the inventory on the connecting flight.

I have a SDC dilemna and would value everyone's experience... I'm booking travel for myself and my mother to Hawaii from EWR in January. I took advantage of the saver award promotion and booked the nonstop on Jan 20, and returning on Jan 27. I am holding off on my ticket because I would like to earn PQMs on this trip, but the nonstop flights are $200 more than the 1-stop itineraries via LAX/SFO (books into G).
Should I go ahead and book the cheaper fare and hope for a SDC to the nonstop (my concern is whether the G bucket would open up), or change the award flights to the 1-stop and SDC everyone at T-24?

I'm relatively new to having SDC available to me with no fee and still haven't actually used it yet. Am I correct that if I'm departing an airport with only one UA flight per day — in my case, POP — and the flight is always at the same time, that I can't do SDC to the day before unless that flight is delayed for at least a couple of hours, but that I might be able to SDC to the next day's flight?
Also, I'll be flying POP-EWR-BOS in late December, which might leave me 300 PQM short of Platinum. I can't do anything with the POP-EWR segment, since it's the only flight UA apparently operates out of POP, but is there any chance I'll have SDC options once I get to EWR that might allow me to add a segment and get that 300 PQM, or will my SDC options — if I had any to begin with — evaporate as soon as I depart POP? Thanks very much.

- Regarding your first point, the SDC framework does not permit for a change to the next/prior day's flight as it is +/- 24 hours outside of scheduled departure
- You can SDC en-route, so as soon as you are on the aircraft for your POP-EWR flight, you can check the app to see if there are options to change your EWR-BOS flight to EWR-IAD-BOS, etc.

How does your mother feel about taking $50 for a nice meal and flying separately?

This used to be 3.5h, and is now 2h, so it is a downgrade. However, they will force space for you even if you don't see it if you are within 2h.

2 DPs about SDC and going on standby for a previous day flight if the intended flight is full:
DP1: I originally had a flight departing Wednesday, 7am, CHO - ORD - SEA and I wanted to get on a flight that departs on Tuesday, 10am CHO - IAD - SEA. The Tuesday CHO - IAD segment was booked full, so I went to the airport hoping to be placed on standby. Check in agent could not clear me onto the standby list, but a supervisor could and I eventually got onto the flight and landed in SEA almost a full day early.
DP2: 2 weeks later, same situation on the same routings, however both CHO - IAD and IAD - SEA were booked full. This time the only supervisor was also on leave and agent had to call their backend to try to put me on the list. Backend agent could not put me on the list and instead wanted me to pay for the fare difference and change fee to get on the Tuesday flight (which is SOP). At that time, I was still unaware that you had to be on a flight that is departing on the same calendar day to be eligible for standby (I thought it was for flights departing within 24 hours of the original itinerary), so I told the agent to go ahead with the transaction. In my mind I was intending to email 1kvoice to get the charges reimbursed. Turns out the backend agent had difficulty charging my card, so she placed me on the waitlist without charging me, while giving me a confirmed flight to the next IAD - SEA flight that was not full. I landed at IAD, cleared the standby for the IAD - SEA flight that was full, and got to SEA almost a full day early again.
Interestingly, I was booked into full Y in DP1, while I retained my original fare class in DP2.
Since then, I realized that I had to be on the same calendar day to get on the standby list and have not dared to try doing this again.

I would not count on SDC'ing multiple pax, especially on a combo of revenue and award tix, as UA may never open X. Even if it's just you SDC'ing from the OS to NS, I suspect it's going to be difficult/impossible to get seats together. Finally, while they should open G prior to clearing NRSA, there's always the risk the NS is completely full and you can't SDC onto it. Not sure this is a situation where I would be relying on SDC for a seat on the flight I really want.

Thanks - ended up splitting the difference and will book both tickets with the nonstop on the outbound and the one-stop via SFO on the return. Maybe I'll get lucky and get to SDC onto the nonstop coming home. Now if they'll just open up fare buckets lower than S on the outbound nonstop...
Are you going to be looking for X(N) or I(N)? When I looked at doing something sort of similar, it seemed X is almost as likely as G to open up, but I is far less likely (seems like CPUs clear before I has a chance to open).
Also beware that 1-stop itineraries sometimes ticket as broken fares, and then you have no realistic hope of SDC to the nonstop.
How does your mother feel about taking $50 for a nice meal and flying separately?

I'm currently on a 016 ticket flying NH, then connecting to an AC flight with a UA flight number.
I'd like to push out the AC flight.
Do I have any chance of doing this? If so, what's the best option? I'm thinking try in the app once I'm airborne on the first flight, and if that doesn't work, then again when I land. If the app won't do it, then try to find an agent?
Edit: GFL agent said she could do it for $75. AC*G and UA*S... so close
She also said I could try again in SFO, so I'll do that.

No chance the app will do this. Some agents will go outside rules. Have been problems report if the flight operator does not accept the change.

SFO check-in agent had no issue moving me to a later flight, though she had to call the AC counter to offload me first. I said very little (I just got in from Tokyo, and I'd like to take a later flight so I can go into the city for lunch), and she never mentioned a fee.
However, I'm now booked in U class. Originally, it was Z, but there was no F space on any other flight today. I'm fine with Y, but I would have expected Y, not U.
Oh well, the plan now is to push this out until I actually need to get to YVR, so I guess I'll deal with fare class issues when it becomes a problem.

Aeroplan Award SDC Question
If I have an Aeroplan award ticket (on United) from ATL-IAD-EWR can I SDC to go direct ATL-EWR?
If no, can I SDC to an earlier flight from IAD-EWR. (the layover at IAD is like 5.5 hours) and there are two scheduled planes in between the time that I landed and the one that I am suppose to take.
Thanks in advanced.
Scheduled on UA 330
ATL 2:33pm IAD 4:24pm
IAD 5:10pm, 7:05pm departures options
My departure UA 1581 IAD 10:05pm EWR 11:25pm
Direct ATL-EWR available at 1:45pm and 3:55pm
If no, can I SDC to an earlier flight from IAD-EWR. (the layover at IAD is like 5.5 hours) and there are two scheduled planes in between the time that I landed and the one that I am suppose to take.

No. SDC is not possible on tickets issued by other airlines. If partner award seats are available on ATL-EWR -- which is what you'd need for an SDC -- you may be able to change to that flight via Aeroplan, but whatever their fees are would apply.
