Irkutsk International Airport (IKT) serves as the main air gateway for eastern Siberia and typically functions as a regional hub for both domestic and occasional international services. Expect a mix of Russian carriers and low-cost operators on routes to Moscow, Siberian cities and select seasonal international connections; fares can be competitive on domestic sectors. The airport lies about 50 km (roughly 30 miles) from Irkutsk city center; road transfer by taxi or private car usually takes 40–60 minutes depending on traffic, while express shuttle buses are available and can take around 60–75 minutes with lower fares. Pros: straightforward layout and decent domestic connectivity; cons: distance from central Irkutsk and limited late-night international options.
Tribhuvan International Airport (KTM) is Kathmandu’s main international gateway and the country’s busiest airport, handling both most international services and a large share of domestic flights. It typically hosts full-service carriers on regional and long-haul routes alongside Nepal’s domestic airlines and several budget regional operators. Located about 6–10 km from central Kathmandu, travel time to Thamel or the city centre can be roughly 20–45 minutes depending on traffic; typical transport options include taxis (metered or fixed-fare, commonly used), ride-hailing apps where available, and private transfers — fares and journey times can vary widely given congestion. The airport can be convenient for direct connections and quick access to the city, but facilities and queues can sometimes be crowded during peak periods, and services may not match larger international hubs in space or amenities.
