If you've been sitting on a modest stash of United miles and eyeing a trip to London, this is a solid opportunity. Economy awards from Boston (BOS) to London Heathrow (LHR) are pricing at 36,800 miles with minimal taxes—just $6. That's a meaningful discount from the roughly 60,000 miles United typically charges for this transatlantic route.
Availability appears wide open for April 24, 2026, which gives you plenty of time to plan around school schedules or coordinate with travel companions. Spring is a pleasant time to visit London, with milder weather and fewer crowds than the summer peak season.
The low taxes are worth highlighting here. Many European award tickets come with substantial carrier-imposed surcharges, but $6 out of pocket makes this redemption particularly clean. For a family of four, you're looking at under $25 total in fees.
One practical note: United's award pricing is dynamic, so these rates can shift without warning. If this works for your schedule, it's worth locking in sooner rather than later.
