Just to confirm - I was specifically referring to booking class translation, per my first post in this thread (post #3). I knew what booking class I purchased from UA; one that earns 1.0x. I received 0.5x. While DC later gave me 1.0x on appeal, Guy Betsy suggested that the reason for the original 0.5x may have been LX's translation of the UA class into a different class of their own, which may have correctly posted as 0.5x. I was saying there's no easy way to find that LX class, not that it was difficult to find the UA class I had purchased. It wasn't.

(At the time I was concerned that the difference between 0.5x and 1.0x, ZRH-BOS, might affect my requalification for Gold. As it happens it won't, but I was only a month into my DC year at the time and didn't plan to a trip to South America next week.)
