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 you'd typically pay for this route.

This is a solid opportunity for families planning a spring trip to London. United MileagePlus is pricing economy awards from Los Angeles (LAX) to London Heathrow (LHR) at 40,000 miles one-way, with minimal taxes and fees of just $6. Availability appears wide open for April 10, 2026.

For context, economy awards on this route typically run around 60,000 miles through United, so this represents roughly 33% savings. That's 20,000 miles back in your pocket per person—meaningful savings for a family of four.

The low tax figure is worth highlighting. Transatlantic awards can sometimes carry hefty surcharges depending on the carrier, but $6 keeps this deal genuinely affordable beyond just the miles.

One practical tip: April is shoulder season in London, meaning fewer crowds and milder weather compared to summer. If your schedule allows flexibility, this is a pleasant time to visit with kids before peak tourist season kicks in.
