London is served by several airports with distinct roles. Heathrow (LHR) is the city’s primary international hub, commonly used by full-service carriers and for long-haul flights; it sits about 15–20 miles west of central London and can be reached by the Heathrow Express (15–20 minutes, higher fare), the Elizabeth Line and Piccadilly Line (35–50 minutes, moderate fares), or road (variable time/cost). Gatwick (LGW) to the south is a major point for both leisure and low-cost carriers, roughly 28–35 miles away with rail links (30–40 minutes by Gatwick Express or Southern services) and coach options. Stansted (STN) and Luton (LTN) typically cater to budget airlines and charters, located farther out to the northeast and northwest respectively; expect longer transfers (40–70 minutes by train or coach) at generally lower ticket prices. London City (LCY) is a smaller, business-oriented airport within about 6 miles east of the center, offering fast connections to the financial district (10–20 minutes by DLR) but with limited route choices and stricter luggage limits. Pros across the network include broad airline choice and frequent services; cons can include variable transfer times, peak crowding, and differing additional costs for rail/coach or checked baggage.

Tribhuvan International Airport (KTM) in Kathmandu is Nepal’s main international gateway and typically functions as the country’s primary hub for both full-service and regional carriers, with international flights from airlines like Nepal Airlines, Druk Air, and several South Asian and Middle Eastern operators. Fares to Kathmandu can be perceived as moderate to premium depending on season and routing. The airport sits about 5–7 km east of Thamel and the city center, with taxis taking roughly 20–40 minutes (metered fares or fixed rates typically apply) and private transfers slightly quicker; local buses and hotel shuttles are also available for lower-cost options. Pros: close to central Kathmandu and relatively compact for short transfer times. Cons: can be crowded and facilities are more basic compared with larger international hubs, and occasional weather or congestion delays can affect punctuality.
