This is a solid option for families planning a spring trip to London. At 44,000 miles per person, you're saving roughly 16,000 miles compared to the typical 60,000-mile rate for economy awards on this route. The taxes and fees are just $33, which is notably low for transatlantic travel to the UK.

Availability is wide open on April 18, 2026, so you should have no trouble booking multiple seats together if you're traveling with kids or a group. That kind of availability is often hard to find on popular routes to London, especially as you get closer to departure.

One practical tip: if you don't have enough United miles, remember that MileagePlus partners with Chase Ultimate Rewards, so you can transfer points at a 1:1 ratio. Just make sure the award space is still available before initiating any transfer, as it can take a few minutes to process.
