This fare prices out at roughly 35,000 miles less than the usual 110,000-mile rate you'd see for transatlantic business class through Aeroplan. At current point valuations, that's a meaningful savings for a summer departure to London.

The availability is for July 8, 2026, which falls right in peak summer travel season when award space to Europe tends to be scarce. Only 3 seats are showing, so this could work for a couple or a small family, though larger groups will need to look elsewhere.

Keep in mind that Aeroplan miles can be earned through a variety of transfer partners, including American Express Membership Rewards, Chase Ultimate Rewards, and Capital One. If you're short on Aeroplan miles, a transfer from one of these programs could help you lock in this rate.

One practical note: London Heathrow has some of the higher airport fees in Europe, but at $108 total, the taxes here are quite reasonable for a business class redemption to the UK.
