A couple of points

1) Your interpretation of the AA/CP/AY codeshare question was right.
2) Its not definite at the moment - only if Iberia and Canadian join the bonus
3) The only status you would get is Gold on American because 100000 of the points in each program are bonus points.
4)The 1st class fare ex-Calgary is $C12149 and $US300 for an extra business class segment in Asia.Economy would cost around $CAD4500 if you could stand it. My 1st class ticket bought in South Africa is $US6000 and the cheapest place for an Economy ticket I think is here in Australia where it would cost $US2000. Going economy would mean around 40000 less points.
5)Will I be doing this? I don't think so. I'd prefer to maintain Platinum on American and forgo 100000 Finnair points I think. so I might try for 4 or maybe 5 of the bonuses.
