How about
www.virtuallythere.com ?
CX locators are in 5 digits. I think they start with either K or H.
(Your travel agent or airline apparently made a reservation using a computer reservation system different from CX's. There is usually a duplicate CX 5-digit locator that matches your 6-digit locator.)
You can also check your itinerary on
www.cathaypacific.com but you need to join AsiaMiles and enter your AsiaMiles membership number in the record. If you do not want to earn AsiaMiles, change the FFP number to the one you like when you check in.
