This award availability is on April 9, 2026, flying from LAX to LHR in business class. At 120,000 miles, you're saving roughly 20,000 miles compared to the usual 140,000-mile price point for this cabin and route. The $6 tax and fee total is notably low for transatlantic travel, as UK-originating flights typically carry much higher surcharges.
With only 2 seats showing, this works well for a couple or a parent traveling with one child. Families of three or more will need to get creative with separate bookings or look for other dates with more availability.
April in London offers mild spring weather and fewer crowds than summer, making it a solid time for a family trip. You'll also be traveling before peak season pricing kicks in for hotels and attractions.
One practical note: award space like this can disappear quickly, especially with just two seats. If this date works for your schedule, book first and sort out the rest of your plans afterward. United allows free cancellation on award tickets up to 24 hours before departure for MileagePlus members.
