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

American AAdvantage is showing first class award space from Boston to London for 85,000 miles per person, which is well below the typical 200,000-mile rate for this premium cabin.

This transatlantic first class award from Boston (BOS) to London Heathrow (LHR) is available for April 28, 2026. At 85,000 miles one-way, it represents a 57% discount compared to the roughly 200,000 miles American typically charges for first class on this route.

A few things to keep in mind: only 2 seats are currently showing, so this works for a solo traveler or a couple, but larger families will need to look elsewhere. You'll also need to budget for the $1,538 in taxes and fees that come with premium cabin awards departing from or arriving in the UK.

Those surcharges are steep, but if you have a stash of AAdvantage miles and value the first class experience, this is still a solid redemption. At standard rates, you'd be spending more than double the miles for the same seat.
