I think Aeroplan is making a killing on $90 change fees

!!!!
In September last year I booked a points business class ticket to Whitehorse for July this year.
One leg - Vancouver to Whitehorse is in economy. Every morning I do a quick check to see if a business class seat has opened up but no luck so far.
I noticed during these daily checks that availability changes dramatically. Seat availability comes and goes often (except the flight I want lol). I have seen the availability calendar go from almost white = no availability to totally yellow = seat available just about every day and then back again to no availability again = lots of changes, and I am looking at business class seats only

...
I decided to take a different approach today to getting my business class seat = buying an extra Lotto 6/49 so I can win and just pay for the seat
