Read through this thread, but I didn't come across any post regarding Aeroplan award bookings.
Can MCO's be used to cover the payment of the taxes/fees/levies for award bookings and possibly also the $30 Aeroplan call centre booking fee?
Not sure if this matters, but my MCO reads as follows:
Type of service for which issued = Future travel, Excess baggage
Endorsements = Non Ref / AC Only
