I'm likely going to hit SE by the end of next month, due to a combination of the rollover SQM/S/D that everyone got last year, plus the extra bonus rollover for having the premium credit card, plus some very expensive cash fares during this double-SQM/S/D promotion going on until the end of April. Will be nice to get it so early, as it will keep me set through to the end of 2023.

Is there any way (other than special COVID-related special rollovers) to earn rollover SQD? Basically, I'm wondering if I should keep flying cash fares throughout 2021, May - Dec. (after I hit SE), or if I should just call it a year and start burning through my many Aeroplan points, if cash fares beyond SE won't have any additional/rollover benefits.

I know I could roll over up to 200K SQM based on my TD Visa Infinite Privilege credit card, but that isn't super helpful if I can't get any SQD to roll over.

Thanks!
