Award space has opened up on the Chicago (ORD) to London Heathrow (LHR) route for April 12, 2026, with United pricing economy seats at 40,000 MileagePlus miles. The taxes and fees come in at just $6, making this a solid option for families looking to stretch their miles on a transatlantic trip.

This rate compares favorably to the typical 60,000-mile price tag you'd normally see for economy awards on this route. That 20,000-mile savings per person adds up quickly when you're booking for a family of four.

Availability appears strong at the moment, but award space to London during spring travel season tends to get snapped up. If your dates are flexible around mid-April, it's worth checking nearby dates as well to see if the same pricing extends to other departures.

Practical tip: If you're short on miles, United credit card holders can often transfer Chase Ultimate Rewards points to MileagePlus at a 1:1 ratio to top off their balance.
