Best Aeroplan Business Class sweet spots

US-Europe at 70,000 Aeroplan miles one-way + $250-350 in fees is the cheapest Star Alliance Business Class redemption from the US. Bookable on United Polaris, Lufthansa Allegris (the new Extra-Long bed variant included), SWISS, Austrian, Air Canada Signature, and TAP Portugal. Aeroplan does not pass through fuel surcharges on Lufthansa metal the way British Airways Avios does on BA metal, so the fees stay genuinely low.

Aeroplan transfers 1:1 from Amex Membership Rewards, Chase Ultimate Rewards, Capital One Miles, and Bilt Rewards. Marriott Bonvoy also transfers at 3:1. Citi ThankYou does not currently transfer to Aeroplan. The 1:1 ratio from Amex/Chase/Capital One/Bilt makes Aeroplan one of the most accessible Star Alliance currencies for US-side card holders.

Aeroplan for almost every redemption. United MileagePlus usually charges more miles (80,000-110,000 to Europe vs Aeroplan's 70,000) and its dynamic pricing often spikes during peak periods; neither program adds fuel surcharges to partner awards. Aeroplan prices partner awards on a fixed distance-and-region chart, which keeps them predictable (Air Canada's own flights are priced dynamically). The exceptions: United-operated flights (use MileagePlus on those for slight savings), or when you have surplus MileagePlus and no Aeroplan.

Star Alliance saver-level Business space typically opens 11 months before departure and is most available in the 6-11 month window. Inside 30 days, saver space is hit-and-miss. For specific routes: ANA "The Room" JFK-NRT/HND has very limited saver availability and books months in advance. Lufthansa releases saver Business space 14 days before departure (last-minute window for those with flexible schedules).

Yes, but expensive. Lufthansa First Class via Aeroplan is 140,000 miles one-way US-FRA + ~$300-400 fees. Lufthansa First saver availability opens 14 days before departure (booking earlier than 14 days requires premium-level award space which costs more). Most Aeroplan members book Business (70K miles) instead and add a paid Lufthansa First Class Terminal day-pass for the lounge experience.

No. Aeroplan adds no fuel surcharges to award tickets, on Air Canada or on its partners: you pay government taxes plus a flat CA$39 partner booking fee. That keeps the cash co-pay far below programs that pass surcharges through, such as Lufthansa Miles & More on Lufthansa flights. Note that British Airways is not an Aeroplan partner, so BA flights need Avios or another Oneworld program.
