If you've been sitting on Aeroplan miles and eyeing a spring trip to the UK, this is a reasonable time to book. Boston to London Heathrow is available for 32,000 miles in economy, with just $40 in taxes and fees—a straightforward redemption without the fuel surcharge pain that often plagues transatlantic awards.
For context, economy awards on this route through Aeroplan typically run around 50,000 miles, so you're looking at savings of roughly 18,000 miles per ticket. For a family of four, that adds up to 72,000 miles back in your pocket for future trips.
Availability appears wide open for April 30, 2026, which lands right at the tail end of London's shoulder season—decent weather, fewer crowds than summer, and prices that haven't yet climbed to peak levels. Worth noting that late April also means you'll catch the city in bloom.
One practical tip: Aeroplan allows stopovers on award tickets, so if you're flexible, consider routing through a Canadian hub and adding a night in Montreal or Toronto at no extra mileage cost.
