i am going to make exe plat again. thinking if it is worth to requalify next year. as i have 26 J segments on oneworld. if i fly cx and credit to aa, i earn 245% miles vs 350% when i credit to as. as miles worth 40% or 50% more than aa, so i am getting 50% value less whenever i credit jl, cx, qa, to aa.
so i am paying real opportunity cost when i try to requalify aa exec plat. (this year, i credit all.qr flights to aa and non qr to as, so i am not paying the opportunity cost)
