Effective December 6, 2016, Aeroplan's flight reward fee structure for changes and refunds will be updated as per the above chart, replacing the previous flat fee of C$90 plus taxes per ticket.
For any flight reward bookings made prior to December 6, 2016, the previous non-refundable fee of C$90 plus taxes applies. For members with Aeroplan diamond status, in the event that the new fee structure is more favourable, the lowest fee will be applied if the change or refund is made after December 6, 2016.
