I'm planning my summer trip across Asia right now and I'm comparing fares. However, it is not possible to check fares to some major Asian cities on AC's website. I'm talking about places like Taipei, Kuala Lumpur and Jakarta... AC has tons of codeshares within Europe and the US, but it is impossible to book a flight to any of the above cities on AC's website.

I'm wonder why AC doesn't use Tokyo or Seoul as hubs to offer easy connections that are bookable online. They could also codeshare with these airlines to Manila instead of using CX.

That's my suggestion for AC. Instead of using up codeshare numbers on flights operated between two cities already served by AC (Houston - LA) use them on places they don't fly at all.
