I'm still going thru the info, but CX earning is horrid in Y.

Y, B 100%/1.00
H 100%/0.50
K, M, L, V, Q, S, G, N 0%/0

JL is awful too:

Full-Fare Economy Y, B 100% – 1.00
Discount Economy H, K, M 70% – 0.50
Discount Economy L, V, S, G, O, R 50% – 0.50
Discount Economy N, Q 30% – 0.50

So not only do they gimp your base miles, but then they chop your EQMs in half on top of that. 15% total EQMs?
