This is a solid option for families planning a spring trip to London. At 44,000 miles one-way plus just $26 in taxes, you're looking at a straightforward redemption without the hefty carrier-imposed fees that often plague transatlantic award tickets.
For context, economy awards on this route typically price out around 60,000 miles through United MileagePlus. That makes this deal about 16,000 miles cheaper per person—meaningful savings if you're booking for a family of four.
Availability appears wide open for travel on April 20, 2026, so you have some flexibility if your dates shift slightly. April is a pleasant time to visit London, with milder weather and fewer crowds than the summer peak season.
One practical tip: if you don't have enough United miles on hand, remember that Chase Ultimate Rewards points transfer 1:1 to MileagePlus, often instantly. This can be a good way to top off your balance before booking.
