Tribhuvan International Airport (KTM) in Kathmandu is Nepal’s primary international gateway and typically functions as a busy hub for both full-service carriers and regional airlines, with budget operators serving domestic and short-haul routes. It sits close to the city center — roughly 5–7 km east — and is usually reachable in 20–40 minutes by taxi or rideshare depending on traffic; fares can often range from modest local rates to higher amounts during peak times. Ground options include airport taxis, metered city cabs, and some hotel shuttles; public bus connections exist but can be slower and less frequent. Pros: very convenient for downtown access and multiple carrier choices; cons: facilities can be crowded and infrastructure may feel basic compared with larger international hubs.

Bangkok’s Suvarnabhumi Airport (BKK) is the city’s primary international gateway and a major Southeast Asian hub, handling most full-service carriers and long-haul flights. It’s located about 30–35 km east of central Bangkok; typical taxi rides to Siam or Sukhumvit take 30–60 minutes depending on traffic, while the Airport Rail Link connects to the city in roughly 25–35 minutes with fares usually in the low single-digit USD range. Pros: modern terminals, plentiful lounges and dining options, extensive international connections. Cons: can be busy and spread out, transfers may require extra time during peak hours. Don Mueang International Airport (DMK) serves as Bangkok’s budget and domestic-focused airport, commonly used by low-cost carriers and regional services.

Pros: budget-friendly fares and quick processing for low-cost airlines; facilities are functional and compact. Cons: fewer long-haul options, limited premium amenities, and transfers between DMK and Suvarnabhumi can add time and cost if you need to change airports.
