My recommendations for better web experience on cathaypacific.com are:
1. The ability to change seat preference after checking online via the airline's website.
2. Better airfare display when using the online booking from the expert tool section on the right hand side of the front page rather than having to click from "More fares from Hong Kong to...." section on the Hot Offers area.
3. Update the seat maps with the latest information. Some of the information on fleet and seat maps are old and outdated.
Other than that, the website is one of the airline benchmark for functionality, interactivity and layout. I hope the e-Business department at CX works towards improving the above three recommendations.
As always, Fly Cathay Pacific - the world's best airline! ^
