(Small) Aeroplan Pricing Glitch with Premium Economy

A reader sent me an email about a glitch he’s been having searching for flights on Aeroplan (and I got his permission to post about it). It seems that if there’s a Premium Economy segment on one end, and a Business segment on the other, the entire itinerary prices as a Premium Economy redemption. Now, there’s not a whole lot of benefit out of this, although if there’s an affected routing that you were considering booking anyways, this can save you points.
