As long the routing rules allow the stopover then you can change to give yourself more stops in between your origin and destination points.

Does anyone know if you can SDC from a CO-operated flight to a UA-operated/CO-coded flight?

I have a LIM-EWR-xxx flight coming up that I'd like to switch to LIM-IAH-xxx. However, LIM-IAH is operated by a UA 763.

Thanks,
RM

Officially, no. But the website has been known to be confused from time to time. ;)

Has anyone tried to extend a layover before? e.g. - I have a IAH-LAX-HNL ticket and I have 2 hours layover in LAX (IAH-LAX and LAX-HNL booked as different segments [multi-city] but in 1 PNR and it's a IAH-HNL fare). Is it possible for me to take a IAH-LAX sector say 20 hours earlier and leave my LAX-HNL intact, thus allowing me to spend a day in LA?

The SDC fees apply to everyone in the PNR elite or not.

I can't find a post on this when doing a search for Same Day Change, so I apologize if this is somewhere else...

When flying to/from a city with only one flight a day, can I do a SDC for exactly one day later?

No. A handful of people have posted here that they found an agent who would make an exception but I certainly wouldn't assume that.

This is without doubt one of the most confusing parts of SDC. According to the website, you can make a change within 24 hours of a flight for free if you are standing by for the new flight within 2-3 hours of the new flight or you can get a seat without standing by if your fare bucket is available on the new flight within the 24 hour time frame. I have included a link to the CO page for those interested in the exact wording.

Same calender day changes are not a problem for most GAs and TAs. Your flight is at 5 PM and you want to leave at 11AM? Make the change after 5PM the day before (24 hours) if the fare bucket exists and get a seat, or stand by at the gate for an available seat. No problem

Here is where problems begin. Let's say your flight is at 10AM on Friday but you want to take the 7PM on Thursday. If you read that link very carefully, this does not seem to be possible.
[Copy from link page]: Requested flight can be in any fare class and be departing within the next 24 hours from when you are making the request.
The words "departing within the next 24 hours....." and that word next is the problem. IF that is true, then technically my example of a SDC leaving on the same calender day but earlier than my original departure would be illegal. But it isn't and we all know that. So why would my second example be any less legal. It is still within the 24 hour time frame for a change, and if the fare bucket is open, then the change should be made and a seat given. If the fare bucket is not open, then I should be able to stand by for the flight within 2 hours (maybe 3) for an available seat. Yet the blow back I get from GAs and phone agents is fierce. They say that you cannot make a change that goes over a calender day.

So, what is right??

:confused: You're over-complicating this, in my opinion. I believe the language on the website makes sense, and have always been able to get agents to make the change I wanted without question (actually you can make these changes online the vast majority of the time):

You are on a 10am flight on Friday, as per your example, and want to move to a 7pm Thursday flight. There are only two conditions (besides the fare class availability, which is common in all cases):

- You can only make the request within the OLCI window for your original flight (starting at T-24hrs)

- The flight you want to move to has to be departing within 24 hours of when you make the request.

It really is that simple. So OLCI opens at 10am Thursday for your original flight. At that point you can book yourself on any other available flight between ~11am Thursday and your original 10am Friday flight - including the one you want on Thursday evening. If you wait an hour longer (11am Thursday) you can now rebook onto flights departing up to 11am Friday, and so on.

This is what the language on the website says, and this is how it's always worked for me. It was confusing in the past when there was the 12hr limitation, but it is far more intuitive now.

Non-confirmed standby is only available at the airport so it rules out any flights after your original one, but the process for earlier flights is the same.

Any expetience with the opposite situation? Changing a CO ticket UA operated flight to a CO flight via the website?

which website? CO website won't let you check in on a UA flight, and I don't know if UA offers the change on its website.

Did a search and didn't receive a definitive answer so I figured it was worth asking. I'm on CO booked CO metal flight this coming Friday. Any idea if I'll be able to SDC onto a UA operated CO code share? (assuming there's seats)

Currently on PIT-IAH-SEA and hoping to go on an earlier PIT-ORD-SEA. If I'm not able to confirm at the 24 hour check in, has anyone had luck getting on to a UA flight at the airport on day of travel in my situation?

I'd have to take a half day off from work in order to attempt the above and I'd hate to waste a half day of vaca time trying something that's not permitted.

Thanks for any advice.

If PIT-IAH looks overbooked, there is a possibility. But I doubt it's worth the half-day of losing vacation for it.

Just to add my question. Has anyone tried to use SDC for a flight with a segment with CO and the conecting segment with CM (Copa)? I have an IAH - MIA - PTY that i would like to change for a IAH - FLL - IAH - PTY but this change would have all segments on CO. Any help would be appreciated as my flight is for this friday :D

Didn't work for me via the website but I was able to have a UA agent offload me from my UA metal flight and SDC to an earlier CO metal flight 10 days ago. Not seamless by any stretch, but it worked.
