If you've been sitting on a United MileagePlus balance and eyeing a trip to London, this is a solid opportunity. Award space is available on April 25, 2026, flying business class from Boston (BOS) to London Heathrow (LHR) for 88,000 miles. The taxes and fees are minimal at just $26, which is notably low for transatlantic premium cabin travel.
For context, this route typically prices at around 140,000 miles for business class through United's dynamic pricing. At 88,000 miles, you're getting roughly 37% off the standard rate—a meaningful difference if you're trying to stretch your points balance across multiple trips or save miles for future redemptions.
Availability appears plentiful for this date, which is good news for families or groups trying to book multiple seats together. April is also a pleasant time to visit London, with mild spring weather and fewer crowds than the summer peak season.
A practical note: if you don't have quite enough miles, United does allow you to combine miles with cash, though the cash rates aren't always favorable. You may be better off transferring Chase Ultimate Rewards points to top off your balance at a 1:1 ratio.
