Award space from LAX to London Heathrow is available on April 18, 2026, at 40,000 MileagePlus miles plus $6 in taxes. Availability appears strong, so families looking to book multiple seats should have good options.
This is a solid discount from the typical economy award rate of around 60,000 miles for this route. The minimal taxes are also notable—transatlantic awards can sometimes come with hefty carrier surcharges, but this pricing keeps out-of-pocket costs low.
April is a pleasant time to visit London, with spring weather settling in and crowds lighter than the summer peak. If you're planning a spring break trip that extends into late April, this could work well for families with flexible school schedules.
One practical note: United award pricing is dynamic, so these rates can shift. If this fits your travel plans, it's worth booking sooner rather than later. You can always cancel United awards for free if plans change.
