Istanbul Airport (IST) serves as Turkey’s primary international hub and is typically used by full-service carriers and Star Alliance, SkyTeam and oneworld partners alongside Turkish Airlines’ extensive network. Located about 35–45 km northwest of the historic peninsula, journey times to the city center range roughly 35–60 minutes by taxi or airport shuttle depending on traffic; public transport options include the Havaist express buses (fares vary by route) and Metro M11 connections that can be faster during peak hours. IST usually feels modern and well-equipped, with plentiful lounges and dining, though its size can mean longer walks and occasional crowding. For budget-conscious travelers, transfer costs and travel time to central districts can be higher than at smaller airports. Sabiha Gökçen International Airport (SAW) operates mainly as Istanbul’s secondary international and low-cost-focused gateway, commonly serving budget carriers and regional flights. It sits approximately 35–45 km on the city’s Asian side, with road transfers to central Kadıköy or Taksim typically taking 40–70 minutes depending on traffic; options include municipal Havatas/Havaist shuttles, regular buses and taxis with modest fares, and a commuter rail connection that can reduce congestion-related delays. SAW usually offers straightforward, budget-friendly operations but can have more limited transfer and lounge facilities compared with the main hub; it’s often favored by price-sensitive travelers and those staying on the Asian side for shorter commutes.

Tribhuvan International Airport (KTM) in Kathmandu is Nepal’s main international gateway and typically functions as the country’s primary hub for full-service and regional carriers, with budget airlines also operating on popular routes. It sits relatively close to downtown—roughly 5–8 km—so road transfers often take 20–40 minutes depending on traffic; shared taxis and hotel pickups are common, with private taxis and ride-hailing available at higher rates. Domestic flights to mountain airstrips depart from a separate terminal area within the airport, usually serving smaller carriers. Pros: central location and straightforward connections to city hotels; cons: can be congested and facilities may feel basic during peak periods, so allow extra time for check-in and security.

The cost of a one-way flight from Istanbul to Kathmandu ranges from $245 (August 2026) to $356 (May 2027). On average, the ticket price is about $277–$284.
