Well I didn't expect to do this, but I ended up logging 31,000 miles this year on Star Alliance carriers. You need 35,000 to hit Aeroplan Elite (which=Star Alliance Gold), but you also need a minimum of 10,000 of those miles to be flown on AC.
So, I'm semi-frantically searching for ways to bank that kind of AC mileage before year end. (MSP-YYZ-YVR is just over 5,000 mi round trip; but it's more than $800 and I can't really spend that 2x.)
So...toward my quixotic goal - anyone have any tips for finding super-low AC fares? (As if there's going to be any between now and the end of December, I know... )
