Heathrow (LHR) is London’s primary international hub, typically handling long-haul and premium carriers such as British Airways and many global alliances. It sits about 15–20 miles west of central London, with the Heathrow Express connecting to Paddington in roughly 15–20 minutes (higher fares), the Elizabeth Line and TfL Rail taking about 30–40 minutes at lower cost, and various coach and tube options available. Travellers can expect a full-service airport experience with extensive lounges and shopping, though congestion and longer walking/transit times between terminals can be a downside for tight connections. Gatwick (LGW) operates as a major secondary international airport, often hosting a mix of full-service and low-cost airlines; it’s commonly used for both leisure and short-to-medium haul routes. Located approximately 25–30 miles south of central London, the Gatwick Express reaches Victoria in about 30 minutes (premium fares), while regular trains and coaches take 30–60 minutes with cheaper tickets. The airport can be a good balance of choice and price, but passengers should allow time for transfers and occasional crowds during peak holiday periods. Stansted (STN) is primarily positioned as a low-cost and short-haul gateway, frequently serving budget carriers such as Ryanair and other European operators. It’s roughly 35–45 miles northeast of central London; Stansted Express trains reach Liverpool Street in about 45–50 minutes, and coaches typically take 60–90 minutes depending on traffic with more economical fares. The airport often offers competitive fares but can feel more basic in amenities and may require extra time for road transfers to the city. Luton (LTN) functions largely as a budget-focused airport, often used by low-cost carriers for European and some leisure routes. Around 30–35 miles northwest of central London, travelers can use shuttle buses to Luton Airport Parkway and trains to St Pancras in roughly 30–45 minutes combined, or direct coaches that take 50–90 minutes depending on traffic; costs are usually modest. Facilities are generally functional and aimed at quick turnover, which suits cost-conscious passengers but can be less comfortable for longer waits or complex itineraries. London City (LCY) serves as a convenient urban airport, typically catering to business travelers and short-haul regional services due to its close-in location and shorter runway. It’s about 6–8 miles east of central London, with the Docklands Light Railway (DLR) providing a 20–30 minute link to Bank and Canary Wharf at moderate fares; road journeys can be similar or longer depending on traffic. The airport’s compact layout usually means fast check-ins and quick transfers, but aircraft size and route options can be limited compared with larger London airports.

Lisbon Humberto Delgado Airport (LIS) serves as Portugal’s main international gateway and typically hosts a mix of full-service carriers, European network airlines and a large budget/low-cost presence. It sits about 7 km (4–5 miles) northeast of the city centre, making transfers relatively short: the metro takes around 20–30 minutes to central Lisbon with fares usually in the low-single-digit euro range, while taxis or ride-shares can be 15–25 minutes depending on traffic and cost more. Frequent regional and intercontinental connections make it convenient for onward travel, though peak hours can mean crowded terminals and queues; smaller suburban alternatives can be cheaper but less direct.

The cost of a one-way flight from London to Lisbon ranges from $40 (November 2025) to $107 (December 2025). On average, the ticket price is about $72–$149.
