AC Has To Honor CPSA While Air Canada can change the number of Aeroplan Miles under the Aeroplan Program awarded to members per flight without Aeroplans consent, Air Canada is required to purchase, on an annual basis, a pre-established number of Aeroplan Miles at a specified rate. The annual commitment is based on 85% of the average total Aeroplan Miles actually issued in respect of Air Canada flights or Air Canada airline affiliate products and services in the three preceding calendar years. The estimated minimum requirement for 2017 is $209.8 million. Air Canada, including other Star Alliance partners, is Aeroplans largest Redemption Partner. Air Canada pays a fee to participate in the Aeroplan Program which is based on the Aeroplan Miles awarded to Air Canada customers who travel on AC Flights and is included under Gross Billings in the financial statements of Aimia. The CPSA also provides that Aeroplan shall, in return for a service fee, manage Air Canadas frequent flyer tier membership program, Air Canada Altitude, for Air Canadas Super Elite 100k, Elite 75k, Elite 50k, Elite 35k and Prestige 25k customers, as well as perform certain marketing and promotion services for Air Canada, including contact centre services for the frequent flyer tier membership program.
