London is served by several airports that cater to different traveler needs. Heathrow (LHR) is the main international hub, handling long-haul and premium carriers and often being perceived as pricier; it sits about 20–25 km west of central London, reachable by the Heathrow Express in ~15–20 minutes or by Piccadilly Line tube in ~45–60 minutes, with fares typically ranging from mid to higher levels depending on service. Gatwick (LGW) to the south is a large international airport with a mix of scheduled and leisure airlines; train links to Victoria or London Bridge take ~30–40 minutes and can be mid-priced, while coach services are usually cheaper but slower. Stansted (STN) to the north-east tends to host low-cost carriers and charter flights, located roughly 50 km from the center; frequent Stansted Express trains take ~45–50 minutes and budget coaches take longer for lower fares. Luton (LTN) northwest of the city is another budget-focused option with many low-cost airlines, about 40–50 km out; trains plus shuttle buses or direct coaches typically take ~30–60 minutes and are often among the most economical. London City (LCY) sits close to the financial district and is oriented toward business and short-haul European services; it’s only about 10 km from central London and reachable by DLR in ~20–30 minutes, commonly seen as convenient but limited in long-haul options. Pros across the network include frequent connections and transport variety; cons can include congestion, transfer times to central London, and variable costs depending on airport and service chosen.

Santiago is served mainly by Arturo Merino Benítez International Airport (SCL), the country’s primary international gateway and a regional hub for full-service carriers like LATAM and several international airlines. Located about 15–20 km northwest of downtown Santiago, the airport is typically reached in 20–40 minutes by taxi or ride-hail, with fares commonly ranging from moderate to premium depending on time of day and traffic; a bus transfer to the city center can take 40–60 minutes and is usually cheaper. SCL offers a mix of premium lounges and budget-friendly facilities, making it convenient for international connections, though peak-hour traffic and security queues can affect comfort and transit times.
