This availability is on April 24, 2026, routing from Boston Logan (BOS) to London Heathrow (LHR) in business class. At 88,000 miles per person, you're looking at roughly 37% off the typical 140,000-mile rate we usually see for this route and cabin through United MileagePlus.
The low taxes are worth noting here. Transatlantic business class awards often come with hefty carrier surcharges, but this booking rings up at just $26 in fees per ticket. That makes a meaningful difference if you're booking for multiple family members.
Availability is limited—only 5 seats are showing as of this writing. If you're considering this for a family trip, you'll want to move quickly. April is a pleasant time to visit London, falling after the peak winter crowds but before summer pricing kicks in for hotels and attractions.
One practical tip: if you don't have 88,000 United miles on hand, remember that Chase Ultimate Rewards points transfer 1:1 to United MileagePlus instantly. Check your balances across programs before booking.
