A while ago there was discussion about pending changes to standardize paid fare codes on oneworld carriers. Today I received FF tickets from Cdn+ which had codes unlike those used in previous tickets I've received. (In fact, the itinerary spelled out my BA flights as being in Coach rather than First, which made me panic and call immediately! Flight codes did represent F-class seating, but computer had not been properly re-programmed to translate the new fare codes introduced last month, according to agent.)

So, does anyone have this info? Seems "U" is Business Class and "Z" is First Class for FF tickets.

Thanks
