There is a current promotion with Aeroplan where you can earn up to 120,000 bonus points for up to 4 round-trips from Canada to London when you register here, reserve by August 24, 2014 and fly by
September 30, 2014. Due to Greenwich Mean Time (GMT), the registration page will remain active until August 25, 2014 at 02:59 Eastern Standard time.
Below is a breakdown on how you will earn the bonus points:
The offer is valid for Aeroplan members residing in Canada, United States, and United Kingdom. You need to fly on direct non-stop flights operated by Air Canada between a city in Canada and London, England. You will also need to travel a minimum of 2 one-way trips (a round trip would do it).
Keep in mind that the bonus Aeroplan points will not qualify for Altitude Qualifying Miles towards Air Canada Altitude for elite status.
This is a free promotion to sign up for to help you earn Aeroplan points. If you are making a trip to London anyway, you can earn a lot of free points, so take advantage!
