Economy flights from Chicago O'Hare (ORD) to London Heathrow (LHR) are available through Aeroplan for 33,600 miles plus $44 in taxes and fees. The travel date is May 2, 2026, and there's plenty of availability showing in the system right now.
This is a solid discount compared to typical Aeroplan pricing on this route, which usually runs around 50,000 miles for economy. You're saving roughly 16,400 miles per ticket here, which adds up quickly if you're booking for a family.
May is a pleasant time to visit London before the peak summer crowds arrive, and locking in award seats this far out gives you flexibility to plan around school schedules and other travel.
One practical tip: Aeroplan allows stopovers on award tickets, so check whether you can add a stop in Canada on your way to London at no extra miles cost. It's a useful perk that many travelers overlook.
