If you've been sitting on a stash of United miles and waiting for a good time to book a family trip to London, this is a solid opportunity. Economy awards from Los Angeles (LAX) to London Heathrow (LHR) are pricing at 40,000 miles each way, with minimal taxes and fees attached.

This rate is notably lower than the ~60,000 miles United typically charges for this route in economy. The $6 in taxes is also refreshingly low—transatlantic award tickets often carry much higher surcharges depending on the carrier. Availability appears to be wide open for April 4, 2026, making this a good option for families who need multiple seats.

United's award pricing is dynamic, so these rates can shift without notice. If your schedule has any flexibility, it's worth checking nearby dates to see if similar pricing extends across the month. April is shoulder season for London travel, meaning fewer crowds and mild weather—a nice bonus for family trips.

How to book: Search and book directly through United's award search tool at https://www.united.com/en/us/book-flight/united-awards/search. Log into your MileagePlus account, enter your dates, and look for "Saver" availability to lock in this rate.
