Checking my email just now and I see this offer that has a little over 3 hours left! If you register and book Economy Flex or higher fares by 7:59pm ET tonight you'll earn 100% bonus Aeroplan miles on those flights that are within Canada or between Canada and the U.S.

REGISTER AND BOOK HERE

Here are the T&C's

• You must be an Aeroplan Member. If you are not an Aeroplan Member, you can visit the Aeroplan website (www.aeroplan.com) and enroll today. Membership is free.
• Must register on December 29, 2017. A one-time registration is required and can be completed online on this page.
• The Bonus Aeroplan Miles for eligible flights flown will be awarded for new bookings only made on December 29, 2017, by 19:59 Eastern Time inclusively, for travel on select eligible flights between December 29, 2017, and June 30, 2018.
• In order to qualify as a new booking, the booking must have been created for the first time with a new booking reference number during the eligible booking period of the promotion. Any booking made prior to the start of the promotion that is subsequently changed to include travel dates within the qualifying travel period will not be considered a new booking that is eligible for the promotion.
• Only valid on select eligible scheduled non-stop or direct flights operated by Air Canada (including flights operated under the Air Canada Express^® banner) and Air Canada Rouge^®, for travel between December 29, 2017, and June 30, 2018.
• To qualify for the 100% Bonus Aeroplan Miles, the eligible round trips or two one-way flight segments must be travelled in the eligible fare options (booking classes) as follows: Economy Flex (although Tango and Flex fare options share certain booking classes, only Flex fare option purchases will be eligible for a bonus mile offer; Tango fare option purchases are excluded and are not eligible for a bonus mile offer); Economy Latitude; Premium Economy lowest; Premium Economy flexible; Premium Rouge; Business Class lowest; Business Class flexible.
• For example, for itineraries booked in a Flex fare option, 100% of the bonus mileage will be assessed for every two segments. When booking a Flex fare option and travelling from Toronto (YYZ) to Montreal (YUL), basic mile accumulation amounts to 314 Aeroplan Miles per segment, for a total of 628 Aeroplan Miles per round trip. Based on the 100% Aeroplan Mile promotion, a member would earn an additional 628 Bonus Aeroplan Miles, which is based on the accrual percentage when purchasing a Flex fare.
