Tribhuvan International Airport (KTM) is Nepal’s main international gateway and the country’s busiest airport, handling most long-haul and regional flights alongside a mix of full-service and low-cost carriers. Located about 6–8 km east of central Kathmandu, travel time to Thamel or the Ring Road is typically 20–40 minutes depending on traffic. Ground transport options include taxis (metered or fixed fares), ride-hailing services, and occasional airport shuttles; fares can vary widely but are generally modest by international standards. The airport is convenient for onward connections and central hotels, though it can be crowded and facilities are more basic compared with larger global hubs. Security procedures and peak-hour congestion can slow transfers, but KTM remains the most practical arrival point for most visitors to Kathmandu.
