Any chance oneworld will ever get "enhanced" enough for RTW tickets to give full mileage credit on all airlines also in coach? Right now it's a joke. For example, there are only 3.5 carriers out of 8 which give full AAdvantage miles for M class: AA, AY, LA, and BA (for some countries of residence, 0 for others). CX 0, EI 0, IB 30%, QF 70%. CX even has a better FF agreement with Qualiflyer than with their oneworld partner AA. Quite amazing.
