IndiGo is the most frequently operating carrier on Kolkata–Kathmandu, running typically one to two nonstop departures daily. Air India also maintains a schedule. On the Nepali side, Buddha Air and Himalaya Airlines operate domestic and some cross-border routes, though availability from Kolkata specifically varies by season. Yeti Airlines, which had a tragic accident in 2023, has been under review — verify its operational status before booking. The total daily seat capacity on this sector is relatively modest, so booking ahead (especially during Dashain and Tihar) is important to avoid sold-out inventory.
Indian nationals do not need a visa for Nepal and can stay indefinitely — there is no tourist visa fee or time limit for Indian citizens under the 1950 India–Nepal Treaty of Peace and Friendship. However, you must carry a valid Indian passport or an Aadhaar card as proof of identity at the Tribhuvan International Airport immigration counter. Voter IDs and PAN cards are not universally accepted at the Nepal immigration desk, and a passport is the most reliable document. There is no departure tax that you need to pay at the counter, as it is embedded in the ticket. For full entry details, see /visas.
The great-circle distance from Netaji Subhas Chandra Bose International Airport in Kolkata to Tribhuvan International Airport in Kathmandu is approximately 1,090 km. Block time is typically 1 hour 50 minutes to 2 hours. The final approach into Kathmandu is one of the most dramatic in Asia — the aircraft descends sharply into the Kathmandu Valley, surrounded on all sides by Himalayan ridgelines. Sitting on the right side of the cabin (window seat on rows with a port-side A/B assignment) often gives clear views of Langtang and nearby peaks on clear mornings.
Tribhuvan International Airport (KTM) is the only international airport in Nepal and is located about 6 km east of central Kathmandu (Thamel). The airport is compact and can be chaotic during peak periods — the single terminal handles all arrivals. Indian nationals proceed to the Indian citizens' lane at immigration, which is typically faster than the general (visa-on-arrival) lane. Taxis from KTM to Thamel are a short 15–25 minute ride; metered taxis are available but negotiate the fare before getting in, as meters are rarely used. Expect ≈ NPR 600–1,000 (≈ ₹380–₹640) to Thamel.
Kathmandu's best seasons are October–November (post-monsoon, clear skies, ideal for trekking and Dashain/Tihar festivals) and March–April (rhododendron bloom, mild weather). Both windows see high air-ticket demand from Kolkata. The Dashain window (typically September–October) is the single most in-demand period — seats can disappear 3–4 weeks ahead. Budget fares from Kolkata to Kathmandu typically range from ≈ ₹7,000 to ₹20,000 return depending on season and booking lead time. The June–September monsoon is the cheapest time to fly but visibility for the Himalayan approach is limited.
IndiGo's international fares on this route typically include 20 kg of checked luggage; confirm at booking, as fare-class rules vary. The Nepalese rupee (NPR) is the local currency; 1 Indian rupee = 1.6 Nepali rupees (rate as of 2026). Indian currency notes up to ₹100 are accepted as legal tender in Nepal; ₹200, ₹500, and ₹2,000 notes are NOT accepted in Nepal by law. Carry smaller Indian denominations or exchange to NPR at the Kathmandu airport, where rates are reasonable. ATMs in Thamel dispense NPR and accept Indian debit/credit cards.
Netaji Subhas Chandra Bose International Airport (CCU) is about 16 km north-east of central Kolkata (Park Street, Esplanade). Kolkata Metro's Airport Line (Line 6) was under construction with stations near the airport — verify operational status as of your travel date. Until Metro connectivity is confirmed, Ola, Uber, and pre-paid taxis are the most reliable options; fares to central Kolkata range from ≈ ₹350–₹600. Budget 60–90 minutes during peak-hour traffic, especially for morning departures that catch the city's famous congestion.
No. Indian nationals do not require a visa for Nepal and have no time limit on their stay under the 1950 bilateral treaty. You need a valid Indian passport (most reliable) or an Aadhaar card as identity proof at Kathmandu immigration. See <a href="/visas">/visas</a> for details.
Yes. IndiGo typically operates one to two nonstop Kolkata–Kathmandu departures daily. Air India also has a schedule. Flights take approximately 1 hour 45 minutes to 2 hours nonstop.
Indian rupee notes of ₹50 and ₹100 denominations are accepted as legal tender in Nepal. However, ₹200, ₹500, and ₹2,000 notes are NOT accepted in Nepal by law. Exchange these to Nepalese rupees or use ATMs in Kathmandu.
The June–August monsoon season has the lowest fares (return from ≈ ₹7,000–₹9,000) but cloudy weather limits mountain views. October (post-monsoon) and March–April are peak season — book 6–8 weeks ahead to secure reasonable fares during these popular windows.
Window seats on the right side of the aircraft (typically the A column on a narrow-body, facing north on the approach into KTM) tend to offer the best views of Langtang and surrounding ridges on clear days. Morning flights in October–November have the clearest skies.
Tribhuvan International Airport is about 6 km east of Thamel, Kathmandu's main tourist district. A taxi takes 15–25 minutes and costs ≈ NPR 600–1,000 (≈ ₹380–₹640). Negotiate the fare beforehand as meters are rarely used.
