When I checked with Aeroplan to book a flight at the beginning of January, was told that I no longer had my nearly 50,000 points as I had not used Aeroplan in 2018. No other explanation given, no apology. I checked on line and realized that I should have been given 60 days notice.
I called again and was told that a notice had been sent to me in October; when I said I had not received it, I was told that didn't matter, their records showed they had sent it to me and, too bad (my words) if, for some reason, my computer did not receive it, it didn't matter, notice had been given. I did get a Costco membership in November 2017 and used it all last year, but paying cash.
My only proof is my Costco membership #. My Aeroplan # Is 778 558 635
