Best Of Air Canada
No capacity controls on award redemption at time of booking for SE (top tier) status. The ONLY FFP that I'm aware of where you are not at the mercy of yield management and their impenetrable methodology about how many seats are award vs. revenue, and when seats are finally (if at all) tossed back to award inventory.
FOR INTL. J TRAVEL, THERE IS NO PEER TO AEROPLAN.
Plus, during select times of the year, SEs get award travel at 25-33% off regular award levels, which are reasonable in the first place.
Worst of AC:
For domestic mileage accumulation, AC is now leveraging its market dominance...lousy earning potential.
Upgrades are only transferable to those with same status.
