Do flights from the United States to Canada qualify for Air Miles discounts?

As of 2015, to qualify for an Air Miles discount, flights must originate in North America and include a Canadian city, so a flight from the United States to Canada is eligible. The airline ticket may be a one-way, round-trip or multi-stop ticket.

The number of reward miles needed for an international airline ticket and the remaining cash payment, if needed, are determined by the outbound date of the trip. Booking fees apply on both Air Miles reward and cash tickets, and no cancellations or refunds are permitted. Most tickets may be changed, based on fare restrictions and availability, but a change fee usually applies.
