Effective for bookings made on June 1 and onward. Air Canada Aeroplan is raising prices on partner awards by around 7-20% depending on route and cabin class. Air Canada is one of my favorite options to book premium cabin flights as there are a lot of great Star Alliance options between US-Europe and also to Asia. There are some other caveats for certain partners like United, Emirates, and Etihad but those airlines haven’t had much business award space on AC recently. Full breakdown of new costs can be found in this Air Canada PDF.
Honestly, the devaluation isn’t as bad as it could be. The biggest one is East Coast-Asia in business class seeing a 17% increase in price (87.5k→102.5k). Most East Coast-Europe business class awards will also be going up 7% (70k→75k). Still reasonable, but still annoying.
Those last-minute Lufthansa First Class awards will also go from 100k→120k. Probably the biggest devaluation percentage wise.
