I'm guessing they do a no-promo code require "promotion" combined with another "see your bonus" up to 5x aeroplan points for bookings flown before Dec 31.
Highly doubt we will see an SQX promo.
I've re-qualed for SE already and will likely be a 75k at max next year, so I wouldn't mind a 5x points deal. Great ROI on those combined with 3x on the Reserve and PR power while miles still = points.
