This redemption prices at 49,600 Aeroplan miles one-way, which is roughly 1% below the typical 50,000-mile rate you'll usually see for economy awards on this transpacific route. It's not a dramatic discount, but the real draw here is the abundant seat availability—something that can be hard to come by for Japan travel during cherry blossom shoulder season.
April 21 falls just after peak sakura viewing in Tokyo, which means you'll likely encounter slightly smaller crowds while still enjoying pleasant spring weather. For families planning a longer trip, this could serve as a solid anchor date to build an itinerary around.
Aeroplan miles transfer instantly from American Express Membership Rewards, Capital One, and Chase Ultimate Rewards (at a 1:1 ratio for Amex and Capital One). If you're short on miles, topping off your balance is straightforward.
One practical note: when booking through Aeroplan, pay attention to the routing. Some itineraries may connect through Canada, which can add travel time but occasionally opens up better availability.
