This is a solid redemption for anyone looking to fly the transatlantic route in comfort next spring. At 70,000 miles, you're saving roughly 40,000 miles compared to the typical ~110,000-mile rate Aeroplan usually charges for business class between Boston and London.
Availability appears to be wide open for April 13, 2026, with plenty of seats showing at this price point. That kind of availability is increasingly rare for premium cabin awards to Europe, especially at a discounted rate.
The low taxes are worth noting too. At just $114, this avoids the hefty carrier-imposed surcharges that can make some transatlantic business class redemptions feel like less of a bargain. That combination of reasonable miles and reasonable fees makes this a genuinely useful sweet spot.
If you don't have Aeroplan miles on hand, remember that the program partners with American Express Membership Rewards, Chase Ultimate Rewards, and Capital One, all of which transfer at a 1:1 ratio.
