i use asia miles too but i don't think it's very difficult to get the miles wor....usually i'll transfer my points from credit card to my asia miles account if i want to redeem tickets.
yes ar....
Asia Miles need more points to redeem air ticket. eg Japan and Singapore, as bby have said, need 35000 points whereas for aeroplan (air canada program) needs only 20000 points.
but of course Asia Miles can gain points via dining or retail or credit card transfer in HK, but not for aeroplan. what i meant as 'difficult' is that for asia miles, even though you can earn miles from dining or shopping, most of them are expensive business.
and you have to pay a charge for transferring credit card points as well.
