This is a solid opportunity for families looking to book a spring trip to London without burning through their miles balance. At 29,600 miles per person in economy, you're looking at well below the roughly 50,000 miles Aeroplan typically charges for transatlantic economy awards. The $84 in taxes is also reasonable for a flight touching the UK.
Availability appears wide open for April 5, 2026, which means you should have flexibility when booking multiple seats together. April is a pleasant time to visit London, with milder weather and smaller crowds compared to summer months.
Aeroplan is a transfer partner of American Express Membership Rewards, Capital One, and Chase Ultimate Rewards, so you have several options for topping off your balance if needed. Transfers from Amex and Capital One are typically instant, while Chase transfers can take a day or two.
One practical tip: if you're booking for a family, search for all passengers at once rather than one at a time. This ensures the system shows you only flights with enough seats for your entire group.
