United MileagePlus: Business Class to London for 88,000 Miles (July 2026)

United is showing business class award space from Chicago to London for 88,000 miles plus $51 in taxes, which is about 37% below what you'd typically pay for this route.

This award fare from Chicago O'Hare (ORD) to London Heathrow (LHR) prices out at 88,000 United MileagePlus miles with just $51 in taxes and fees. The travel date is July 19, 2026, which falls during peak summer travel season when award availability to Europe is typically scarce.

For context, business class awards on this route usually run around 140,000 miles through United's dynamic pricing. At 88,000 miles, you're saving roughly 52,000 miles—enough for a separate domestic round-trip or a one-way to Europe in economy.

One important note: there's only one seat available at this price. That makes this better suited for a solo traveler or someone willing to book one family member now and watch for additional availability to open up closer to departure.

Practical tip: If you're short on miles, United MileagePlus partners with Chase Ultimate Rewards, which transfer at a 1:1 ratio. Just keep in mind that transfers can take up to 48 hours, and with only one seat left, speed matters.
