Cheap Flights to Boston (BOS)

Overview

Boston packs four centuries of American history into a walkable, harbour-fronted city that often feels closer to Europe than the rest of the United States. For UK travellers it is one of the most straightforward transatlantic trips: a daytime crossing, a compact centre best explored on foot, and easy add-ons for a wider New England holiday. See the price charts on this page for how fares shift through the year.

Best time to fly to Boston

Late spring (May and June) and early autumn (September and October) are the sweet spot, with warm days, cool evenings and smaller crowds; October also brings New England's famous autumn colours. Summer is peak season — hot, humid and busy around the Fourth of July. Winter is cold and snowy but usually the cheapest time to fly. Check the When to book chart above for the current pattern.

Airlines and routes

Boston Logan (BOS) has a strong year-round schedule from the UK. British Airways and Virgin Atlantic fly daily from London Heathrow, alongside American Airlines, Delta and JetBlue; JetBlue also flies from London Gatwick and has operated seasonal services from Edinburgh. Non-stop flights from London to Boston take around 7 hours 30 minutes flying west and about 6 hours 30 minutes on the return. From Manchester, Glasgow and other UK cities you will usually connect once — via Dublin with Aer Lingus, where US immigration is cleared before you fly, or via Heathrow — for roughly 10 to 12 hours in total.

Things to do in Boston

Compact and full of character, Boston rewards walkers and history lovers in equal measure.

At Boston Logan International Airport (BOS)

Logan sits just across the harbour, roughly 3 miles (5 km) from downtown — one of the closest major airports to any city centre. The Silver Line bus runs free from the terminals to South Station and the subway that locals call the T, while the Blue Line is a short free shuttle-bus ride away. Taxis and rideshares reach central hotels in about 10 to 20 minutes off-peak, and a seasonal water taxi crosses the harbour to the waterfront.

Top tips for finding cheap flights to Boston

• Book around two to four months ahead for the best choice of fares; last-minute transatlantic seats rarely come cheap.
• Fly midweek, as Tuesday and Wednesday departures usually beat weekends, and avoid school holidays and early July.
• Keep your dates flexible and use the price charts on this page to pinpoint the cheapest weeks.
• Compare the full line-up — British Airways, Virgin Atlantic, JetBlue, Delta, American and one-stop Aer Lingus — as fares and baggage rules differ.

Travel essentials

UK passport holders need no visa for tourism: you travel under the US Visa Waiver Programme with an approved ESTA, arranged online before departure and valid for up to two years and stays of up to 90 days. Your passport must be biometric. The currency is the US dollar, and cards are accepted almost everywhere. No vaccinations are required, but healthcare in the United States is expensive, so comprehensive travel insurance is essential. Boston runs on Eastern Time, five hours behind the UK.
