China Airlines Dynasty Flyer recently made changes to mileage credits for Air China flights. First class flights that earn 150 percent of actual miles flown are now available with F and A fares (formerly, it was F only); business class fares earn 130 percent of actual miles flown with C, D or Z fares (formerly C or D only); business class fares that earn actual miles are available with Y and B fares (formerly Y and S); and coach fares earn actual miles with M, H, K, L, Q, G, S, V, U and W fares (formerly B, H, K, L, M, N, Q, T, X, U and E). The changes of note are that members will no longer earn 70 percent of miles flown for some fares — the fares that earned 70 percent will either earn 50 percent or no miles at all. S fares that formerly earned 100 percent of miles flown will now earn 50 percent. B fares that formerly earned 70 percent of miles flown will now earn 100 percent. W, V and G fares that formerly earned no miles will now earn 50 percent. M, H, K, L and Q will now earn 50 percent instead of 70 percent.
