London is served by several distinct airports that cater to different traveller needs. Heathrow (LHR) is the city’s main international hub, typically used by full-service carriers and offering a wide range of long-haul connections; it sits about 15–20 miles west of central London and can be reached by the Heathrow Express in roughly 15–20 minutes (farey can be higher), the Piccadilly Line tube in about 45–60 minutes (lower fares), or by road depending on traffic. Gatwick (LGW) to the south functions as a major point for both legacy and low-cost airlines, usually offering competitive fares; rail links to Victoria take around 30–35 minutes, with coach and car options also available. Stansted (STN) and Luton (LTN) are often budget-oriented, popular with low-cost carriers and typically presenting lower ticket prices; both are 30–60 miles from central areas, served by express trains and dedicated coaches that take roughly 30–60 minutes depending on service, with lower-cost transfers commonly available. London City (LCY) is a smaller, business-focused airport east of the center, convenient for short-haul and corporate routes and reachable by Docklands Light Railway in about 20–30 minutes; it can be pricier but saves significant transit time. Pros across airports include extensive route networks and frequent public transport; cons can be longer transfers for some airports, variable fares for express services, and congestion during peak times.

Suvarnabhumi Airport (BKK) serves as Bangkok’s primary international gateway and functions as a full-service hub for major carriers, typically handling long-haul and regional flights. Located about 25–35 km east of the city center, travel time is usually 30–60 minutes by car depending on traffic; the Airport Rail Link connects to central Bangkok in roughly 30 minutes with fares generally in the low single-digit USD range, while taxis and ride-hailing can be more convenient but costlier. Suvarnabhumi tends to feel modern and well-equipped with lounges and international connections, but peak-hour traffic and longer terminal walks can be downsides. Don Mueang International Airport (DMK) operates mainly as Bangkok’s low-cost and domestic gateway, typically hosting budget carriers and short-haul regional flights. It sits about 20–25 km north of central Bangkok, with road journeys often taking 30–60 minutes; public buses, shuttle vans, and taxis are common options, and fares are usually modest. Don Mueang can be a very practical choice for cheaper fares and quick turnarounds, though facilities are generally more utilitarian than the newer international terminal and some services may be limited outside peak times.
