This fare prices out at about 7% below the typical 110,000-mile rate you'll usually see for this route in business class through Aeroplan. It's not a blockbuster discount, but for a peak summer travel date to one of the most popular destinations in Asia, any savings is welcome.
The August 13 departure puts you right in the middle of summer vacation season, which tends to be one of the hardest times to find award availability to Japan. With only 2 seats showing, this is best suited for a couple or a solo traveler rather than a full family booking.
Keep in mind that Aeroplan is a transfer partner of American Express Membership Rewards, Chase Ultimate Rewards, Capital One, and Bilt Rewards. If you don't have the miles sitting in your account, you can transfer points from any of these programs, typically instantly.
A practical tip: availability like this can disappear quickly, especially with only two seats. If you're seriously considering this trip, book first and sort out the details later—Aeroplan allows free cancellations for a full refund within 24 hours of booking.
