Also, I don't think it is completely correct to say that UA does not allow date changes on partner awards. It is my understanding that you can make date changes to partner awards booked with Mileage Plus miles before departure. After departure you can only make date changes to UA metal segments.
You are right. I have made changes to a UA award iten that included UA, LH and LX for no charge. I had to do it before the trip started. And also, I could only change dates, not the route/cities. That requires a fee as you have to actually cancel the award ticket and have them reissued for the new route.
No changes allowed, even for a fee, once your trip has started.
