If you've been sitting on a stash of United miles and have London on your list, this is a solid opportunity to book a transatlantic trip at a discount. Economy award seats from Boston (BOS) to London Heathrow (LHR) are available for 39,600 miles on April 11, 2026, with plenty of seats showing.
This redemption runs about 34% below the typical rate of 60,000 miles you'd normally see for economy awards on this route. The $6 in taxes is also notably low for a flight to the UK, where carrier surcharges often push fees much higher on other programs.
Availability appears wide open for the April 11 date, which makes this a good option for families or groups who need multiple seats. Spring is also a pleasant time to visit London before the summer crowds arrive.
One practical tip: United's dynamic pricing means award rates fluctuate frequently. If this fits your schedule, it's worth booking sooner rather than waiting, as saver-level availability like this doesn't always last.
