This is a solid opportunity for families or couples looking to experience a lie-flat seat to London without depleting your miles balance. At 70,000 miles one-way, you're saving roughly 40,000 miles compared to the typical 110,000-mile redemption rate for this cabin and route.
The availability is for April 21, 2026, and there appear to be plenty of seats open, which is helpful if you're trying to book multiple tickets together. April is a pleasant time to visit London, with mild spring weather and fewer crowds than the summer peak season.
One practical consideration: the $113 in taxes and fees is reasonable for a transatlantic business class ticket. Some partner airlines and routes can come with fuel surcharges exceeding $500, so this is a relatively clean redemption on that front.
If you don't currently have Aeroplan miles, they transfer instantly from American Express Membership Rewards, Chase Ultimate Rewards, Capital One, and Bilt Rewards at a 1:1 ratio.
