price seems to have gone up uniformly over many countries. as i have connection in Canada, i dont think it is impossible for me to do the Canadian exemption.

i think oneworld is kind of smart to get rid country of origin as the airlines get direct feedback from agents about the good pricing in many places. hence, mpm, cai were shut off very fast.
it is probably harder for any deal to last if people keep on calling AA saying we get DONEx for 4000 USD.. they will send feedback to higher up to pull the fare.
