I am looking to book a trip from BOS-MNL in business on 17 Sept.

routing and Inventory from EF

bos-jfk CX 7663
jfk-hkg CX 841 Inventory J9 C9 D9 I8
hkg-mnl CX 903 Inventory J9 C9 D9 I8

My question is why can't I get AA.com or cathay to show me a discounted Business fare?

I am new to EF so I may not be understanding it correctly.

Thanks!
