This fare represents a solid discount compared to the usual 110,000 miles you'd expect to pay for business class between LAX and LHR through Aeroplan. The $142 in taxes is also reasonable for a transatlantic business class ticket, as some programs tack on fuel surcharges that can run into the hundreds.
There's just one seat available on April 5, 2026, so this is best suited for a solo traveler rather than a family trip. If you're flexible and traveling alone, it's a worthwhile option to consider.
One thing to keep in mind: Aeroplan availability can shift quickly, and single-seat awards like this tend to disappear without warning. If this fits your schedule, it's worth booking sooner rather than later. You can always cancel Aeroplan awards and receive your miles back, though a fee may apply depending on your membership status.
