Just when it seemed members of the Air Canada Aeroplan program had given up on any bonus promotions, along comes a chance for members to earn double or triple miles on flights from Canada to London.

Through Dec. 15, members will earn triple miles for every roundtrip, or two one-way segments, on scheduled flights by Air Canada in Executive First. Members flying economy will earn double miles for the same segments. Members must register to be eligible for this bonus. The good news is that you do not need to register before flying. As long as you register before Dec. 15 and have flown these routes, you get your bonus from Sept. 1.
