Air Canada Aeroplan members who purchase Tango fares will now earn half as many miles on flights made in discounted booking classes (R, G, P, E, N, T, K and X booking classes). Effective Sept. 15, 2007, members will earn 25 percent of distance flown on Air Canada and Air Canada Jazz flights within Canada and between Canada and the continental states (including Hawaii) with Tango fares. If you made reservations prior to July 4 for travel after Sept. 14, you will still receive 50 percent of miles flown.
