There's a single business class seat available on April 26, 2026, flying from Chicago O'Hare to London Heathrow. At 88,000 miles, this is well below the roughly 140,000 miles United typically charges for transatlantic business class on this route. The $30 in taxes and fees is also notably low for a flight to the UK, where carrier surcharges often push fees much higher.
This pricing represents solid value for MileagePlus members looking to get to London in a lie-flat seat. April is a pleasant time to visit the UK, with spring weather and fewer crowds than summer months. Just keep in mind that award availability at this price point tends to disappear quickly, especially with only one seat showing.
A practical note for families: since there's only one seat at this rate, this deal works best for a solo traveler. If you're hoping to book multiple seats together, you may need to search nearby dates or consider mixing cabins.
