So I read that after having cut loose its former air miles division and got Aeroplan going as an independant business some years back Air Canada is going to start a new in-house air miles division from 2020. Is there any info concerning what will happen with Aeroplan, and miles accrued. There is some material suggesting Air Canada may still honour accrued Aeroplan miles after 2020 but I found I could never use them on Air Canada itself for their most benefit effective role, i.e. Business or First, so used them on United and ANA However even Economy never came up as an option except on very circuitous routes on Star Alliance partners. (Maybe on domestic flights one could get actual Air Canada tails.) Aeroplan did have a good points plus pay though, far better than Qantas say so I am wondering more about how Aeroplan might be treated in terms of being a Star Alliance without Air Canada being involved. I am inclined to think Aeroplan miles will be worthless from 2020 so for Star Alliance travel from now on it would be better to be in a different program even if flying Air Canada against which to accrue miles. Are some better than others? I'm thinking of features such as being free to join, longevity of miles, keeping membership open for three years with no activity as Aeroplan does, relatively unrestricted accrual eg not just for fully flexible economy etc. Seeing as Aeroplan worked out Ok for me in terms of utilisation and was pretty good in other aspects my personal preference, if they continue to be a Star Alliance member organisation would be to keep using it for accruing Star Alliance miles, but it is hard to see how it might continue as a member. After using up all but 57 of our miles on a recent First/Business flight from Chicago to Sydney what I figure start a new program now, as I'm looking a a couple of Lufthansa RTW tickets pretty soon.
