Those new flights did not work for my schedule, so I called to get rebooked onto LAX-NRT-LAX on different dates within the +/- 7 day window that UA's schedule change policy permits.
I wonder if that is because of the double dipping with +/- 7 days and preserving the UG? I have not had any issues preserving upgrades when simply re-booking on a sensible connection the same day flights were originally scheduled for.
