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

United is showing business class award space from Boston to London Heathrow for 88,000 miles plus just $33 in taxes, which is about 37% below what you'd typically pay for this route.

This fare is for travel on May 2, 2026, flying Boston (BOS) to London Heathrow (LHR) in business class. At 88,000 miles with $33 in taxes, the out-of-pocket cost is minimal, and the mileage price is well below average for a transatlantic business class redemption.

For context, United MileagePlus typically prices this route and cabin at around 140,000 miles. That makes this a savings of roughly 52,000 miles—enough for a domestic round trip on a good day.

One important note: there's only 1 seat available at this price. That limits this deal to solo travelers, so it won't work for family trips unless you can find additional availability on connecting flights or nearby dates.

Practical tip: If you're flexible, search surrounding dates to see if similar pricing appears. Award space to London can fluctuate, and United sometimes releases additional seats closer to departure.
