Hmm, MR points are getting more and more useless now.
Aeroplan to N. Asia: 75/125K/175K (one-way more expensive, $90 fee to change anything including date)
United to N. Asia: 65K/120K/140K (one-way is 1/2 of round-trip, $0 fee to change date)
Does Aeroplan generally block Star Alliance flights?
For BA, I still have two companion voucher(2x$30K spend on CCs) which will expire in April and July 2012. I looked at the BA YQ for Biz/First to Europe and they are terrible and don't think I will be able to use them, really regretted that I've put $60K spend on these BA cards.
SPG and Chase UR are the ways to go now.
