Three airlines show nonstop award space between Toronto and Calgary: Air Canada, Porter Airlines, and WestJet. As a Star Alliance member, Air Canada also sells its nonstop through alliance partners, not only Air Canada Aeroplan. For connecting options, the better-priced awards in the data connect in Chicago. In economy, the floor sits on Air Canada, booked through Star Alliance partner Avianca LifeMiles. Only four airlines show award inventory on the route, so date flexibility matters more than carrier choice.
