Air Canada may not be the greatest airline, but it has one of the best frequent flyer programs in the world. Air Canada is also member of Star Alliance, which includes airlines such as Singapore Airlines, All Nippon Airways, United Airlines and Scandinavian Airlines, allowing for greater reach as well as more options to accumulate and redeem miles.
If you want to take advantage of Aeroplan, Air Canada’s newly redesigned frequent flyer program, your first step is to obviously set up an account. Then, your second course of action if you have some residency/connection in Canada (irrespective of your citizenship) is to get the American Express Aeroplan Reserve Card.
