American AAdvantage: First Class to London for 85,000 Miles (April 2026)

American AAdvantage is showing first class award availability from Boston to London for 85,000 miles on April 9, 2026—a solid option for families or travelers with miles to burn, though the high taxes make this one worth calculating carefully.

This award opens up first class travel from Boston Logan (BOS) to London Heathrow (LHR) at 85,000 AAdvantage miles per person. Only three seats remain at this price, which could work for a small family or a couple traveling together.

The pricing represents a meaningful discount from what you'd typically see. First class awards on this route through American usually price closer to 200,000 miles, making this roughly 57% below standard rates. That said, the $1,538 in taxes and fees per ticket is substantial and worth weighing against paid business class fares or other redemption options.

For families considering this redemption, do the math on your total out-of-pocket costs. Three seats would run you 255,000 miles plus $4,614 in taxes. If you have a stash of AAdvantage miles that might otherwise expire or devalue, this could be a reasonable use—but if you're flexible on cabin class, you may find better overall value elsewhere.

Award space like this tends to disappear quickly, so if the numbers work for your situation, don't wait too long to book.
