Happy New Years to all / Xin Nian Kuai Le 2011 from TPE!

Just wondering if anyone has experience using RT bundle tickets ex-China for TPE-YYZ/YVR travel?

Came across updated 2011 prices here:
http://www.aircanada.jp/pdfs/Bundle-cnen.pdf

The bundles fares are really great but I've had problems with availability for AP tickets on CA for TPE-PVG/TSA-SHA and there are no CA flights leaving PVG or PEK that depart after AC flights arrive from YVR and YYZ.

Fares to YYZ to ex-NRT are really affordable and better AP availability on NH and UA but the change/cancel penalties for AC tickets issued in Japan are unreal...even for M Class, the penalties are in the 200-350 dollar range?
