Let us say I have Air Canada Aeroplan card, and if I shop at certain retailers, I accumulate points. Now let us say a particular flight on air Canada cost 100,000 miles. How to know how many points are worth a mile? Is this relationship changing continuously, and if so where can I find the most recent conversion rate?
The plan is that when I buy something , I should have at least a rough idea how many 'miles' I am accumulating, not just how many points.
