I recently made a trip in United Basic Economy (N class). It was rather nice with *G from Asiana: free carry-on and checked bag, early boarding and lounge access.

Oddly enough, now that my miles have credited it looks like I have earned both redeemable miles and status miles at the 50% rate. Or at least, on my "Membership status" page the "Asiana Airlines and Star Alliance Miles" number has incremented by the amount I earned for the trip. I won't complain, but clearly something is inconsistent in their IT system compared to what the customer service told the poster above.
