This is a straightforward deal for families looking to get across the Atlantic without burning through their miles balance. Boston to London Heathrow is pricing at 31,000 Aeroplan miles per person in economy, with just $46 in taxes and fees. For a family of four, that works out to 124,000 miles total rather than the usual 200,000 you'd expect to pay.
The typical rate for this route through Aeroplan runs around 50,000 miles in economy, so you're saving roughly 19,000 miles per ticket here. Availability appears to be wide open for July 12, 2026, which is notable since summer dates to London are usually the first to get snapped up or price at premium levels.
Aeroplan is a transfer partner of American Express Membership Rewards, Capital One, and Chase Ultimate Rewards, so you have multiple ways to top off your balance if needed. Transfers from Amex and Capital One are instant, while Chase transfers typically complete within 24-48 hours.
One practical note: if you're booking for a family, search for all passengers at once to confirm availability before transferring any points. Award seats can disappear quickly, and you don't want to be stuck with miles in Aeroplan and not enough seats for everyone.
