A few more problems I will help consolidate from other threads + my own observations:

Star Alliance flights do not seem to appear when you go to purchase a ticket. I regularly book NZ/UA or SQ/UA tickets on united.com - so this will be a problem. Not sure if it is just that you have the links cut for the time being - and I have ensured that "United Airlines Flights ONly" is not checked (it use to be that you clicked include star-alliance flights).

A GS is complaining about long hold times - and I have experienced the same (gave up after 35 minutes on hold as a 1K). I assume this might be tied to the whole IVR only recognizing US zip codes and hence assuming and invalid ID and dropping the calls into the generic queue.

The system charging a 1K for baggage - but that one looks like the new MP number is not recognized as 1K.
