I'm considering whether to re-activate my Aeroplan account with Amex MR points. One factor would be whether redemption inventory on AC metal at the Classic (not ClassicPlus) level, for a non-elite member, is more available using Aeroplan miles than other Star miles (I don't think United general members get additional inventory on UA, for example). Plus factors for Aeroplan seem to be the short-distance North American awards, even in J, which can apparently take you from Atlanta to Sept-Iles, plus access to the networks of other Canadian carriers (can I get to Nunavut?) But what about fuel surcharges for Canadian and transborder travel? Any other thoughts on Aeroplan vs. Kris Flyer, the other main option I'm considering (those miles might be used in the U.S., or Southeast Asia). When do miles expire these days?
