Hi guys : I am a *alliancer and looking to hedge my bets next year. I do about 150k qualifying miles per year, mostly to Asia Pac region/Europe and north america.

Which oneworld program is best to join ? BA,CX or AA ? I am looking to fly 50k on Oneworld airlines next year.

given that I'll be doing most of the north america with Air Canada, that leaves Asia Pac travel and Europe. I do mostly J class travel, but on the occasional Y ticket as well.

my priority is getting upgrades and easy redemption.

so who do I choose ?
