If you're planning a family trip to London next summer, this is a solid redemption worth considering. Boston to London Heathrow is available on August 9, 2026, for 31,200 Aeroplan miles per person in economy, with just $46 in taxes and fees. Availability appears to be wide open, which is helpful when booking for multiple travelers.
This route typically prices out around 50,000 Aeroplan miles in economy, so you're looking at savings of nearly 19,000 miles per ticket. For a family of four, that adds up to roughly 75,000 miles saved—enough for another domestic round-trip or a nice hotel redemption.
Aeroplan miles transfer from American Express Membership Rewards, Chase Ultimate Rewards, Capital One, and Bilt Rewards, all at a 1:1 ratio. If you don't already have Aeroplan miles on hand, transfers from these programs are usually instant or near-instant.
One practical note: August is peak summer travel season for transatlantic flights, so seeing this kind of availability and pricing more than a year out is unusual. If your dates are flexible, it's worth searching nearby dates to see if similar availability exists.
