Heathrow (LHR) is London’s primary international hub, handling long-haul and full-service carriers such as British Airways and many global alliances; it can be perceived as pricier but offers extensive connectivity. Located about 23 km west of central London, transfer options include the Heathrow Express (15–20 minutes, premium fares typically higher), the Elizabeth Line (25–35 minutes, mid-range fares), Piccadilly Line tube (50–60 minutes, lower fares) and various taxis or ride-shares (travel times vary with traffic). Pros: comprehensive amenities, frequent flights and strong global links. Cons: can be busy, security queues may be longer and premium transfers often cost more. Gatwick (LGW) operates as a major international and leisure gateway, with a mix of full-service and many low-cost carriers; fares can be competitive, especially on budget airlines. It sits roughly 45 km south of central London and offers the Gatwick Express (30 minutes to Victoria, premium single fares), Southern and Thameslink trains (30–50 minutes, generally lower fares), coach services and taxis. Pros: a wide choice of carriers and relatively quick rail connections. Cons: fewer nonstop long-haul options than Heathrow and terminals can be crowded during peak holiday seasons. Stansted (STN) is primarily a budget and charter-focused airport serving many low-cost European routes, often perceived as economical for short-haul travel. Located about 48 km northeast of central London, typical transfers include the Stansted Express to Liverpool Street (45–50 minutes, mid-range fares), coaches to Victoria or other hubs (60–90 minutes, cheaper options) and taxis. Pros: competitive fares and many point-to-point routes. Cons: longer rail journeys to central London and buses/train fares may add to total trip cost for late/additional services. Luton (LTN) functions mainly as a base for low-cost carriers and charter operators, commonly used for budget travel across Europe. It lies roughly 55 km northwest of central London; travel options include frequent shuttle buses to Luton Airport Parkway plus regional trains to St Pancras (total 30–50 minutes depending on connection, modest fares), direct coaches to central London (60–90 minutes, often the cheapest option) and taxis. Pros: generally low ticket prices and efficient short-haul routes. Cons: further from the city and transfer times/costs can offset savings on very short trips.

It’s about 11 km from central London (Canary Wharf and the City are nearby), with the Docklands Light Railway (DLR) offering 15–25 minute connections to key business districts, short taxi rides and occasional river services. Pros: proximity to the financial district, quick check-in and transfers. Cons: a smaller range of destinations and stricter aircraft size restrictions than larger hubs.
