Tribhuvan International Airport (KTM) in Kathmandu is Nepal’s primary international gateway and usually functions as the main hub for full-service and regional carriers such as Nepal Airlines, Buddha Air and Himalayan/Air Dynasty operators; it can feel busy given limited apron and terminal space. The airport sits roughly 5–8 km from central Kathmandu, with road transfers typically taking 20–40 minutes depending on traffic; taxis and private cars are the most common options, with local fares usually modest but variable, while hotel shuttles and ride-hailing can be convenient. Pros: compact layout and proximity to the city make arrivals straightforward. Cons: facilities may be basic by international hub standards, security and weather can affect schedules, and congestion is common at peak times.

Ulaanbaatar is served mainly by Chinggis Khaan International Airport (UBN), the country’s modern international gateway located about 52 km south of downtown. It functions as Mongolia’s primary long‑haul hub, handling most international and regional carriers alongside domestic flights; budget and full‑service airlines operate seasonally. Transfers to the city typically take 45–75 minutes by taxi or private car, and there are shuttle buses and occasional airport transfer services with fares that can be modest but vary by operator. Pros: newer facilities and reliable international connections; cons: significant distance from the center and variable road or weather conditions can affect travel times. Domestic hops often use smaller local fields closer to regional centers.
