United MileagePlus: Economy to London for 40,000 Miles (April 2026)

United is offering economy award seats from Los Angeles to London for 40,000 miles plus just $6 in taxes, which is about a third less than what you'd typically pay for this route.

Award space has opened up on the Los Angeles to London Heathrow route for April 19, 2026, with seats pricing at 40,000 United MileagePlus miles each way. The taxes and fees come in at just $6, which is notably low for transatlantic travel to the UK.

This rate represents solid value compared to the typical 60,000 miles United usually charges for economy awards on this corridor. That 33% savings can add up quickly if you're booking for a family of four, potentially saving you 80,000 miles on a round trip for two travelers.

Availability appears to be wide open on this date, so you have some flexibility when planning. April is a pleasant time to visit London, with milder weather and fewer crowds than the summer peak season. If you're planning a spring break trip that extends into mid-April, this could work well.

One practical tip: United award pricing can fluctuate based on demand, so if this rate works for your plans, it's worth booking sooner rather than later. You can always cancel United awards for free if your plans change.
