Reporting:
I flew DME-ADD-JNB and JNB-ADD-DME
DME-ADD min. bid ~600USD
ADD-JNB guaranteed upgrade 500USD
JNB-ADD guaranteed upgrade 500USD
ADD-DME guaranteed upgrade 581USD
I flew business JNB-ADD-DME, I got upgraded for service recovery on JNB-ADD and bought the upgrade outright on ADD-DME because it made sense even though it's a bit pricy.
I think guaranteed upgrades are offered exactly a week before departure provided Business Class is very undersold. JNB-ADD business was mostly full, ADD-DME business almost empty, all middle 2 seaters empty and only windows occupied, mostly by one person.
Best of luck to everyone!
P.S.: Ethiopian really loves operational changes so be on the lookout for that. Also, some 787s suck compared to other configurations. 4A and 4L missing a window.
