See Interline Baggage Agreements (single ticket) when there is a single ticket.
When a passenger has two separate tickets, United will though-check (interline) bags only when the second ticket is for UA or *A partner operated travel. Otherwise, UA may not interline the bags and you will need to recheck bags for the second ticket.
With two qualifying separate tickets, when checking bags thru, you will need to present flight information for both tickets at check-in. This includes the itinerary, PNR and eticket number.
Note: Interlining two UA tickets seems to be challenging for some agents. Allow extra time for bag check, just in case, and perhaps suggest contacting the Help Desk if the agent seems to be having issues.
Interlining UA-UA may not be allowed if one ticket is Basic Economy and does not allow free check bags.
Thread on UA-UA bag interlining
UA.com link
Some conditions when UA may not interlining with another carrier on a separate ticket
Exceptions to the non-partner interlining restriction on separate tickets for 1Ks/GSs have been reported. There still needs to be a regular bag interlining agreement in place.
Additionally, one report suggests that exception would apply also to *Gs and Full Fare J passengers
Whenever checking a bag between carriers (on a single or separate tickets), it is recommended to show your bag tag to each downline carrier at the transfer desk/gate to ensure the bag tag information has propagated to their system.

Thread on UA-UA bag interlining
Effective for travel on and after March 1, 2015, when a customer has two separate tickets, United will though-check bags only when the secondary ticket is for travel on the following carriers:
* United and United Express
* Star Alliance partner airlines
With the new policy, a passenger’s baggage will be checked between the origin and destination points that are reflected on a single or conjunctive ticket.
If the traveler holds a second ticket on another airline beyond the destination of the first ticket, United will check the bag to the destination on the first ticket(s). In such situations, the traveler must collect their baggage on arrival at their first ticketed destination, and then re-check baggage with the next carrier for their continuing flight(s).

If you have a separate ticket on another carrier, you must claim bags at the destination of the first ticketed itinerary and check bags with the other carrier to the final destination. Baggage can be checked through to the final destination if the separate ticketed itinerary includes Star Alliance member airline-operated flights.
- The carrier is not a *A partner
- the connection is overnight
- the connection is less than MCT
- Traveling internationally and connecting to a domestic flight within your destination country
- If the UA ticket is Basic Economy No more "through checking" / interlining of bags when connecting from BE

Default time is 12 hours. A small number of individual stations are enabled to allow bags to be checked thru for connections greater than 12 hours. Maybe we can build a list based on people's experiences for certain connection points.
I know FCO is up to 16 hours. SIN, HND, FRA, MUC, ZRH, BRU should all allow up to 24 hours.

What kind of phone assistance are you looking for 
By the books UA does not interline w/ CX on separate tickets. UA does have an interlining agreement with CX and as a 1K you have a fair chance that the agent at the 1K check-in desk will check it through as a courtesy. YMMV for sure and no recourse if the agent refuses.
Usually, 1K and GS get away with it ... but it will depend on the agent. The GS agent in Boston will always check through

CX is not a UA partner and generally UA will not interline on separate tickets to a non-partner.
However some reports of agents doing this at the airport for higher elites.
You will have to wait till you get at the airport.

US Baggage Interlining
My baggage were checked LAX to HKG on United and HKG to KHH on Cathay Pacific. The baggage arrived in KHH with all the United baggage tags attached. The Transfer point in HKG is a long way from the arrival gate in HKG. The transfer agent for Cathay Pacific wanted to see my baggage claim checks and a ticket for a flight out of Taiwan before issuing a boarding pass.

Flying an Award MUC-LAX in First with LH and wondering if its possible to check luggage through on a separated UA LAX-LAS ticket departuring the same day on a Basic Economy fare?
I know I gotta take through immigration in LAX anyways, but showing UA in LAX I just arrived in First Class with *Alliance, might help to avoid the 30/35 USD fare?
any thoughts/experiences?

Welcome to FT!. slemmo
Interlining bag policy is determine by the initial check-in carrier -- LH in this case. Believe LH generally will do this but best to check in the LH forum.
The BE segment does present problems. If initial carrier was UA, UA would not allow this. So again this needs to be checked in the LH forum (and earlier boarding).
If you don't get LH to interline the bags, showing up at LAX and asking UA to waive the bag check fee with not work.
Changing this to a no-BE ticket for $50 might be worth it to get the interlined bag, no additional bag fee and advance seat selection.

Ua bag interlining on separate carrier ticket
I didn't have any problems last week LAX TO HKG on United. HKG to KHH on Cathay Pacific. Saves a lot of times when the bags are checked to the final destination.

Don’t pre-pay baggage; there’s an excellent chance you’d get it for free.

They will check it through to NH and probably won't charge you for the bag either. Usually when they add a long haul J flight that baggage allowance carries over, but YMMV.

Data point here.
Parents flew PDX-(UA)-SFO-(CI)-TPE last night. These were separate tickets. The United leg was on miles through United, and the China Airlines leg was a cash ticket through China Airlines.
Agent at PDX was able to through check to China Airlines without any issue (and waiving baggage charges due to my parents' Premier Silver status).

Hi all
I have a reward Polaris booking (using A3 miles) EWR-LHR next week.
I have a separate EI LHR-DUB. Will United thru check the bags? I know they’re not codeshare partners anymore but each of their websites say they’re still interline partners. (Travelling on an Irish passport if that matters)
Thanks

Can UA interline my bag during 14hr LAX layover to SQ?
Hi,
I have a trip upcoming this April 12-13. I'm arriving at LAX the "day before" my long-haul flight. I'll have a short overnight at an LAX airport hotel. I'm looking to not have to deal with my checked bag so I can get through security before the SQ check-in desk opens on April 13 and have more time to enjoy the Polaris lounge. That interests me more than twiddling my thumbs in an airport hotel.
Coming in to LAX on UA1710 from ORD. Published arrival time is 23:58 on 4/12. Ticket issued by United is YN economy award fare.
Leaving "next day" (by 2 minutes) on SQ11. Published departure time is 14:20 on 4/13, about 14.5 hours after arrival at LAX. Ticket issued by Singapore is Business Advantage booked with KrisFlyer miles.
I have UA Silver status.
Is it possible for United to interline my checked bag? Should I check in to either flight before I talk to a United agent at the initial check-in desk?
Thank you!
