Cheap Flights from Boston to London — $251

Boston Logan International (BOS) is the region’s main international gateway and a full‑service hub for several legacy carriers alongside many international and low‑cost airlines. Located across Boston Harbor in East Boston, it sits roughly 3–5 miles (10–20 minutes by taxi) from downtown; the free Massport shuttle connects terminals to the MBTA Blue Line, which takes about 15–20 minutes to reach central stations for a small fare. Logan typically offers a wide range of flight options but can be pricier than smaller nearby airports, especially during peak hours. Pros: frequent transatlantic and domestic connections and extensive ground transport; cons: busy terminals, traffic and occasional security queues.

London is served by several airports that serve different traveler needs. Heathrow (LHR) is the main international hub, typically handling long-haul and premium carriers and often seen as pricier on taxes and fees; it’s about 20–25 km west of central London with the Heathrow Express taking roughly 15–20 minutes to Paddington (higher fare), the Underground’s Piccadilly Line about 45–60 minutes (cheaper), and taxis taking 30–60 minutes depending on traffic. Gatwick (LGW) is a large international and leisure-focused airport to the south, usually hosting both full-service and low-cost carriers; it lies ~45 km from central London with a 30–35 minute Gatwick Express to Victoria, slower but cheaper rail options, and coach services. Stansted (STN) and Luton (LTN) are commonly positioned as budget and charter gateways north-east and north-west of the city respectively, often serving low-cost airlines; both can be 40–70 minutes by train or coach to central London with varying fares and longer transfer times, while taxis can be costly. London City (LCY) is a compact, business-oriented airport very close to Canary Wharf and the financial district (roughly 10 km from central landmarks); it typically hosts short-haul business routes and regional carriers, with quick DLR and Tube links making it convenient for corporate travelers. Pros across these airports include multiple service levels and transport options; cons can include variable transfer times, higher peak fares, and potential congestion at the busiest hubs.
