This is a straightforward deal for families or solo travelers planning a summer trip to the UK. Chicago O'Hare to London Heathrow is pricing at 32,500 Aeroplan miles in economy, with taxes and fees coming in at a reasonable $80. Availability on July 12, 2026 looks wide open, which is notable given that mid-July is peak summer travel season.
For context, this route typically runs around 50,000 Aeroplan miles in economy. At 32,500 miles, you're saving 17,500 miles per ticket—meaningful savings if you're booking for a family of four.
Aeroplan is a transfer partner of American Express Membership Rewards, Chase Ultimate Rewards, Capital One, and Bilt Rewards, so you have several options for topping off your balance if needed. Transfers from these programs are typically instant or near-instant.
One practical tip: if you're traveling with kids and want to lock in seats together, book sooner rather than later. Award availability this far out tends to be generous, but seat assignments in desirable rows can fill up as the departure date approaches.
