This is a solid opportunity for families or couples looking to fly transatlantic in business class without depleting their miles balance. At 70,000 miles one-way, you're saving roughly 40,000 miles compared to the typical rate of around 110,000 miles for this cabin and route.
Availability is wide open for April 25, 2026, which gives you plenty of planning time. Spring travel to London means milder weather and fewer crowds than the summer peak, making it a good window for a family trip or a points-funded getaway.
One practical note: Aeroplan is a transfer partner of American Express Membership Rewards, Capital One, and Chase Ultimate Rewards. If you're short on Aeroplan miles, transfers from these programs are typically instant or near-instant, so you can top up your balance before booking.
As always with award space, availability can disappear without notice. If this fits your travel plans, it's worth locking in sooner rather than later.
