For the summer season, from June 1 to October 25, 2019, Air Canada will offer one daily flight between Montreal (YUL) and Nashville (BNA).
In the current Aeroplan fare structure, Tennessee is in the Short-Haul zone from Quebec or Ontario. That means Nashville is accessible for just 15,000 Aeroplan miles roundtrip, with less than $150 in taxes and surcharges.
And since this is a short-haul destination, the AeroplanPlusMD* American ExpressMD Platinum Card annual companion ticket can be used!
More explanations on the companion ticket in this article.
This card is currently on promotion until January 2020.
