This award availability on the Boston to London Heathrow route prices at 31,600 Aeroplan miles, a solid discount from the roughly 50,000 miles you'd typically see for transatlantic economy redemptions through the program. The low taxes of just $45 make this particularly appealing, as London departures often carry significantly higher surcharges.
Availability is wide open for August 11, 2026, which falls during peak summer travel season when award space to Europe can be harder to find. For families planning a late-summer trip to the UK, this is a reasonable opportunity to lock in flights well in advance at a below-average rate.
Keep in mind that Aeroplan is a transfer partner of American Express Membership Rewards, Chase Ultimate Rewards, Capital One, and Bilt Rewards. If you don't have Aeroplan miles on hand, you can transfer points from these programs, typically at a 1:1 ratio.
One practical note: before transferring points, search for availability on the Aeroplan website first. Transfers are usually instant, but confirming the space exists will save you from having miles stuck in the wrong program.
