2021年12月20日前注册，Aeroplan兑换20%折扣。注册直达网页 
成功注册之后，在2022年6月30日前，用Aeroplan兑换加航礼卡，单双程机票，加航假期，酒店，租车。之后会收到20%的Aeroplan退还。
i) an Air Canada Gift Card redeemed at aeroplan.rewardops.com; or ii) for one of the following products or services with travel dates completed by July 1, 2022 at 03:00 a.m. EST (inclusive) (the “Travel Period”): one way or round-trip (including multi city) flight rewards, Air Canada Vacations® packages comprising both a flight and hotel, as well as hotels or car rentals redeemed at aeroplan.cxloyalty.com.
结语
虽然条款中写明适用了TD AP联名卡持有人，但实测发现，所有Aeroplan号码都可以成功注册。是否最后能拿到20%的Aeroplan退还，那就YMMV了。
不过，动动手注册，就是一分钟的事情，说不定真会有呢。
