Don't know about AA in YVR, and I'm not sure AA does yet either. They have not replaced the YVR-ORD flights that the used to codeshare on CP. And in a strange development, effective June 15 they will be discontinuing first class service in to/out of YVR. You'll get the same service you now get, but it will be called business, for about $3 less. Problem is, you'd only get a 25% COS bonus instead of 50%. AA service to other Canadian cities, such as Calgary and Toronto, remains unchanged. (This is not published anywhere -- I simply discovered it by accident. I'll be changing my next Dallas trip slightly to work in the extra 2 segments at the beginning of the trip instead of the end.)

Throwing darts, I'd guess oneworld has something up their sleeve, but that's about as far into speculation as you can get, without drugs. With all the new extra gate space in the transborder terminal, and the increased availability of interational gates due to the reduced number of AC/CP flights, there's now lot's of room to expand. (BTW, check out the new trans-border area, especially when returning to Canada. The area is astounding with running creeks, waterfalls, ponds with "wildlife," recorded sounds of the wild, etc. Quite amazing.)

Admirals Club members should have been allowed to use the YVR CP lounge. But I can't see AC giving up the CP space. As the two lounges are immediately adjacent, I imagine they will soon simply knock out the adjoining wall, and make it one large lounge. Both are currently crowded during peak times. I haven't yet seen enough of the new trans-border area to determine if there is any room for new foreign carrier lounges.
