This transatlantic business class fare from LAX to LHR prices out at 88,000 United MileagePlus miles with only $30 in taxes and fees. For a premium cabin crossing to London, that's a solid redemption worth considering if your schedule lines up.
For context, United typically prices business class awards on this route around 140,000 miles each way. At 88,000 miles, you're saving roughly 52,000 miles—enough for a domestic round-trip on a future booking.
One important note: there's only one seat available at this price. That makes this better suited for a solo traveler than a family trip, though it could work if one parent needs to travel ahead or you're planning an adults-only getaway.
A practical tip: November in London means shorter days and cooler weather, but also fewer crowds at major attractions. If you're flexible on dates, search a few days around November 3 to see if additional availability opens up.
