This fare prices at 75,000 Aeroplan miles compared to the roughly 110,000 miles you'd normally expect to pay for business class between Boston and London. The $143 in taxes and fees is reasonable for a transatlantic award ticket, as some programs and routings can push well above $200.
The catch here is that only one seat is available at this price for the August 13, 2026 departure. That makes this a better fit for a solo traveler than a family trip, but it's worth knowing about if you have flexibility and the points to spare.
If you're sitting on a stash of Aeroplan miles or transfer partners like American Express Membership Rewards, Capital One, or Chase Ultimate Rewards, this is a solid use of points for a summer transatlantic crossing in a lie-flat seat.
A practical note: Aeroplan availability can shift quickly, especially with just one seat showing. If you're interested, search and book promptly rather than waiting to compare options.
