I've got all (except bmi) of Star alliance's FFPs and I'm deciding which one to stick to....
Air Canada's AeroPlan is the easiest to achieve Star Gold with only 35000miles in a year
Thai's ROP is the easiest to achieve Star Silver with only 10000miles in a year
Air New Zealand's Air Point is the best in terms of exchanging points with your house mates (you can take or give miles to all the members who have the same address as you whether they're your family or not!!)
I havent worked out what United, ANA, Lufthansa, Varig and Mexicana's "exclusive" benifits...
Can anyone give me some suggestions??
