So 2 months ago new Aeroplan arrived, based on future travel plans, I ditched my Amex platinum and changed to Amex Aeroplan Plus platinum, got my update of change coming with new card/name coming in November.
Now after 1st statement, my Aeroplan status switched from Black to Diamond , no idea what it meant. ,,,,,, then read here on site,
Beginning in September 2020, and through the end of 2021, 2020 Aeroplan diamond members will receive Aeroplan 25K Status (currently known as Altitude Prestige 25K).

So I guess they are throwing a bone to the CC holders ( at least top level cards, or does any Aeroplan CC get moved to Diamond during transition, can anyone confirm ? )

Still not clear what the h*ll all the benefits are, but seems like it will be worth it,,, if you travel,
