This is a solid redemption for transatlantic business class, especially given how frequently United charges dynamic pricing premiums on popular routes to Europe. At 88,000 miles, you're getting a rate that's well below the roughly 140,000 miles United typically wants for LAX-LHR in a lie-flat seat.
The catch: there's only one seat available on April 27, 2026. That limits the usefulness for families traveling together, but it could work well for a solo trip or if you're willing to split up seating arrangements across cabins.
Taxes and fees are minimal at $26, which is notable for flights into London. UK departure taxes can push fees much higher on the return, so keep that in mind when booking your way back.
If you don't have 88,000 United miles on hand, remember that MileagePlus is a Chase Ultimate Rewards transfer partner at a 1:1 ratio. Transfers are usually instant, but book quickly given the limited availability.
