N & R are fare codes used to be only for award flights and upgrades, but now for some evil reasons, some airlines are using them for PE. Unfortunately, they still credit 0% for most airlines, and the code is not always translated properly when booking a codeshare flight. I do not mind if discounted PE does not get 100%, but it should certainly get something. This seems to be a point of contention that has come up for several of the airlines on this website, but I think it will only be properly resolved if *A gets involved. Has anyone ever had any luck contacting anyone from *A with a complaint? I have tried contacting individual airlines, but they just redirect you to their fare charts and tell you to shove off. I think the only hope here is if they receive a large volume of feedback on this issue.
