Key facts about Boston

How to get cheap flights from London to Boston

Tips and advice from our flight experts

There’s something in the region of 7,204 weekly flights from London to Boston Airport (BOS), which is also known as Boston Logan and, more officially, General Edward Lawrence Logan International Airport. If you’re looking for cheap tickets, it’s worth fine-tuning your search to compare dates, flight times and departure airports. After all, the more you save on the price of your flights, the more money you have left to spend in Massachusetts’ capital city.

For example, London Heathrow Airport (LHR) is the most popular departure airport on this route, although you can fly to Boston from other London airports, like Gatwick (LGW). Try comparing flights from both airports to see if you can find a cheaper price on tickets. The most popular airlines are Virgin Atlantic, Air France and British Airways, as they all offer direct flights to Boston.

An indirect journey might be another option to get cheap flights from London to Boston, if you’re happy to stop off somewhere like Zurich on the way to the US. Indirect flights operate from Heathrow, Gatwick, and London City Airport with one, two or three stops along the way.

As for when to go, July is high season, so flight tickets tend to peak in price. This is Boston’s hottest month, whereas March – the end of winter, when it’s much cooler – is a cheaper time to book. The weather at this time of year can swing from sun to snow in the space of a day, so pack plenty of layers.
