This award availability is worth a look if you've been saving MileagePlus miles for a premium cabin trip to Europe. At 88,000 miles one-way, you're looking at roughly 37% below the typical rate of around 140,000 miles for this route in business class. The low $30 tax and fee amount is also notable, as transatlantic business class awards can sometimes carry surcharges in the hundreds.
The flight departs Chicago O'Hare (ORD) on April 6, 2026, arriving at London Heathrow (LHR). Only 3 seats are currently showing as available, so if you're traveling as a family, you may need to act quickly or consider splitting bookings across different dates.
April is a pleasant time to visit London—spring weather, fewer crowds than summer, and school holiday timing that can work for some families. United's Polaris business class offers lie-flat seats, which makes the overnight flight considerably more comfortable for both parents and older kids.
Practical tip: If you don't see availability right away, try searching one passenger at a time. Award inventory sometimes displays differently depending on party size, and you may be able to book seats individually on the same flight.
