I'm planning to fly CX premium economy to China next year, and CX's website give me outbound on R and inbound on E. But on AS's website CX's premium economy classes are W, E & T. R class is not eligible for any earnings. For double check I checked AA's and BA's websites, they both listed CX's premium economy classes as W, R & E, which makes much more sense. Paid long haul premium economy doesn't earn any miles makes no sense to me. Is CX recently changed R class to paid premium economy and AS is just not up to date yet? Or is there something more complex here? This really freaked me out.
