This is a straightforward deal for families planning a spring trip to London. Chicago to Heathrow is pricing at 33,300 Aeroplan miles in economy, with availability on April 28, 2026. The cash component is minimal at just $52 in taxes and fees per person.

For context, economy awards on this route typically run around 50,000 miles through Aeroplan, so you're saving roughly 17,000 miles per ticket. For a family of four, that adds up to nearly 67,000 miles back in your pocket—enough for another domestic round-trip or a solid hotel redemption.

Availability appears wide open right now, which gives you some flexibility if you need to coordinate schedules or book multiple seats together. That said, Aeroplan pricing is dynamic, so these rates can shift without notice.

One practical tip: if you don't have Aeroplan miles, they transfer instantly from American Express Membership Rewards, Capital One, and Chase Ultimate Rewards (at a 1:1 ratio for Amex and Capital One). Check your balances across programs before booking.
