Airlines flying Kolkata to Kathmandu
IndiGo operates the most frequencies on this short sector, with Nepal Airlines and occasionally Buddha Air also serving the route. Expect ≈ 2–4 non-stops daily, with block time around 1 hour 10 minutes. The flight offers spectacular Himalayan views on a clear day from the right-hand window.
Cheapest time to fly and book
Peak trekking seasons (October–November and March–April) see the highest demand and fares from India. The monsoon months (June–August) are cheapest but less suitable for mountain activities. Booking 3–6 weeks ahead secures competitive fares on this short, popular route.
Flight duration and routing
The non-stop covers just ≈ 560 km in about 1h 10m — barely time for a meal service. One-stop routings via Delhi exist but make little sense given the high direct frequency from Kolkata. Kathmandu is the natural gateway for Everest treks, Pokhara and the wider Nepal circuit.
Baggage and fares
IndiGo's international fares typically include 15–20 kg checked baggage; Nepal Airlines includes 20 kg. Trekking gear often pushes you close to the limit, so check the allowance carefully. Indicative fares are live on FlightGPT as of May 2026.
Airports and terminals
Kolkata international departures use Terminal 2 (T2). Kathmandu's Tribhuvan International (KTM) is compact and often congested during peak season, about 6 km east of the Thamel tourist district. Prepaid taxis are available outside arrivals.
Visa and entry for Indians
Indian citizens need no visa for Nepal and can enter on a passport or Voter ID (for the air route, a passport or Voter ID serves as the nationality document). Nepal's clock runs 15 minutes ahead of India. See our visa guide for document specifics.
