My apologies in advance if this has been asked before - I've used the search function, but either the thread doesn't exist already or I haven't found the right keywords to find it.
Airline fare letter codes are not standardized across an alliance. They can change for each airline. So don't assume that the meaning you know for a particular letter (such as C in this case) has the same meaning at any other OW airline. Chances are it doesn't.
