If you've been waiting for a good time to use your Aeroplan miles for a transatlantic trip, this is a reasonable opportunity. Boston to London Heathrow is available in economy for 32,000 miles on April 9, 2026, with low taxes of just $40. There's plenty of availability showing on this date.
For context, this route typically prices out around 50,000 Aeroplan miles in economy, so you're saving roughly 18,000 miles per ticket. For a family of four, that adds up to 72,000 miles saved—enough for another domestic round-trip.
April is a pleasant time to visit London, with spring weather settling in and crowds still manageable before the summer rush. The timing also works well for families with spring break schedules, though you'll want to verify dates align with your school district.
One practical tip: Aeroplan miles transfer from American Express Membership Rewards, Capital One, and Chase Ultimate Rewards (in Canada), so check your balances across programs if you're a bit short. Transfers from Amex typically process instantly.
