"Access additional Aeroplan ClassicFlight Reward seats on flights operated by Air Canada or
Air Canada Express.
• Elite 35K, Elite 50K & Elite 75K have access to any unsold seat in Economy Class, up to aircraft capacity, in the event that Aeroplan ClassicFlight Reward Seats are no longer available. These rewards require double the amount of Aeroplan Miles as a regular Aeroplan ClassicFlight Reward.
• Super Elite 100K have access to any unsold seat in Economy Class, up to aircraft capacity, and to additional seats in Executive Class and Executive First, in the event that Aeroplan ClassicFlight Reward Seats are no longer available. These rewards require the same amount of Aeroplan Miles as a regular Aeroplan ClassicFlight Reward."
I'm glad I decided not to stop at 75k. I thought there might've been a chance that E75k would have some priority rewards at the classicflight miles.
