Award space has opened up on the Chicago to London Heathrow route in United business class for August 16, 2026. At 80,000 miles plus $6 in taxes, this represents a 43% discount from the roughly 140,000 miles United typically charges for this route and cabin.
The low tax amount is notable here. Transatlantic business class awards often come with fuel surcharges that can add hundreds of dollars to the booking, but this United-operated flight keeps out-of-pocket costs minimal at just $6 per person.
Availability appears strong at the moment, which is worth noting for families who need to book multiple seats together. August travel to London puts you there during pleasant weather and before the summer holiday season winds down.
If you're considering this for a family trip, remember that United allows you to pool miles with up to four other members through its Family Pooling feature, which can help you piece together enough miles for multiple business class seats.
