I noticed a while back that ZRH-YYC (4817) had posted differently than YYC-ZRH (4825), but assumed it was just one of Aeroplan's rare occasional changes to distance, but recently flew YYC-ZRH again and it's at 4825 again. [MENTION=599574]canadiancow[/MENTION], any thoughts as to what's going on here? Is it possible Aeroplan has built their database in such a way that they're not pulling the same distance for both directions?
