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 from LAX to London Heathrow is currently available on April 16, 2026, at 40,000 United MileagePlus miles each way. The taxes and fees come in at just $6, making this a genuinely low-cost redemption for transatlantic travel.

This pricing sits well below the typical 60,000 miles United usually charges for economy awards on this route. That 33% discount means you're keeping 20,000 miles in your account for future trips—enough for a domestic round-trip or a solid contribution toward your next international booking.

Availability appears strong right now, so families looking to book multiple seats should have a reasonable chance of finding what they need. April is a pleasant time to visit London, falling after the peak winter crowds but before summer pricing kicks in.

If your dates are flexible, it's worth searching a few days in either direction to confirm this saver-level pricing holds. Award availability at this rate can shift without notice, so book sooner rather than later if your plans are set.
