Here goes with a Flyertalk type question....
As a Cathay Pacific Marco Polo Club member, I can earn frequent flier miles for Cathay Pacific flights. I can also earn miles for flights taken on any OneWorld carrier (such as BA, Qantas or American Airlines).
Cathay Pacific themselves are a three class airline, having Economy, Business Class and First Class. Likely because of this, their mileage tables only supply the class multipliers for those three. As such, I can only look up the expected miles for a flight in one of those three cabins.
However, British Airways (a OneWorld partner) have an extra class, World Traveller Plus (=Premium Economy), which sits between Economy (World Traveller) and Business (Club World).
When flying in WTP on BA, and collecting miles in the CX Marco Polo Club, what multiplier is used? Do you just earn the same miles as in regular economy, or is it a higher amount?
