Looking for cheap flights from Guwahati to Kathmandu? FlightGPT compares live GAU to KTM fares across every connected source — Indian carriers, Gulf hubs, OTAs and trusted travel agents — and shows the cheapest options side by side. Whether you want a Guwahati to Kathmandu non-stop tomorrow, a last-minute weekend deal or the lowest price three months out, every active Guwahati-Kathmandu fare is one search away.
IndiGo has operated direct Guwahati–Kathmandu flights on a seasonal basis — verify current availability as schedules change. When non-stops are not available, the most efficient routing is GAU–CCU (≈ 1h) followed by CCU–KTM (≈ 1.5–2h) on IndiGo or Air India. Kolkata is the natural hub given its geographic position between Guwahati and Kathmandu. Nepal Airlines and Buddha Air operate within Nepal and have code-share arrangements that may appear on search results. Direct bookings through IndiGo's own website or a metasearch tool like FlightGPT will surface both non-stop (when available) and 1-stop options simultaneously.
The Guwahati–Kathmandu corridor is fairly lightly priced year-round given the short distance, but fares still spike during Nepal's Dashain–Tihar festival fortnight (October–November) and the spring trekking rush (March–April). For budget-conscious travellers from Assam, June–September is the cheapest window, though Nepal's mountain trails are sodden. December and January offer a pleasant, quieter Kathmandu with reasonable airfares — ideal for the city's temples, bazaars and Swayambhunath. Advance purchase of 4–6 weeks is usually sufficient for this short-haul route.
At ≈ 1,030 km, the Guwahati–Kathmandu great-circle distance is shorter than many domestic Indian routes. A non-stop flight (when available) takes roughly 1.5h. Via Kolkata, the two-sector journey adds ≈ 1–2h of connection time. The approach into Tribhuvan Airport from the east is striking — Himalayan peaks, including views of the Kanchenjunga massif on clear days, frame the descent. Unlike most Himalayan airports, KTM's runway is at a manageable altitude of 1,338 m, so mountain sickness is not a concern at the airport itself.
As of June 2026, economy returns on the Guwahati–Kathmandu route (1-stop or direct) typically range from ₹8,000–₹18,000 in off-peak months, rising to ₹20,000–₹30,000 during the October trekking peak. IndiGo's economy includes 15 kg checked baggage on the domestic sector; Air India bundles 23 kg on the international leg. If booking separate tickets for the domestic and international segments, factor in the risk of a missed connection — better to book as a through-itinerary where possible or allow at least 2h of connection time at Kolkata.
Guwahati's Lokpriya Gopinath Bordoloi International Airport (GAU) is located at Borjhar, ≈ 25 km from the city centre; prepaid taxis and Ola/Uber operate the transfer in 45–60 minutes. The airport has a small international terminal. Kathmandu's Tribhuvan International (KTM) is 6 km east of Thamel, Kathmandu's backpacker hub; pre-paid taxis from the arrivals hall run ≈ NPR 700–1,000. Ride apps are limited at the airport itself but available in the city. Note that KTM can experience thick morning fog in December–January, occasionally delaying early-morning arrivals.
Indian nationals do not need a visa or any advance travel permit to enter Nepal. Entry is permitted on a valid Indian passport, an Indian government-issued voter ID, or a driving licence (though an ID card with photo is safest for international air travel). There is no restriction on length of stay for Indian citizens. Indian currency (INR, except the discontinued ₹2,000 note) is accepted widely in Nepal. Nepali rupees can be obtained at Kathmandu airport on arrival. Visit /visas for broader South Asia travel tips and any updated bilateral entry notifications.
October to mid-November is widely considered the best month to visit Kathmandu — the post-monsoon air is crystal clear, Himalayan panoramas are at their finest, and the Dashain and Tihar festivals create a festive atmosphere across the valley. For travellers from Guwahati wanting a quieter, cooler alternative, February offers comfortable temperatures (10–20 °C days), minimal rainfall and significantly lower accommodation rates. Spring (March–April) is excellent for trekking and the rhododendron forests are in full bloom at altitude. The monsoon (June–September) brings lush green valleys but muddy trekking trails.
IndiGo has operated seasonal non-stop GAU–KTM flights. When unavailable, a 1-stop via Kolkata (CCU) is the next-best option, keeping total travel time under 4h.
A non-stop (when available) takes ≈ 1.5h. A 1-stop via Kolkata adds connection time, making the total ≈ 3–4h. It's one of the shortest international journeys from North-East India.
No. Indian citizens do not require a visa. A valid Indian passport or voter ID card is accepted. There is no fee and no advance application needed.
Economy returns range from roughly ₹8,000–₹18,000 off-peak, rising to ₹20,000–₹30,000 during the October trekking season. It's one of the most affordable international routes from the North-East.
IndiGo is the primary option for both direct (seasonal) and 1-stop services. Air India via Kolkata is a reliable alternative with generous baggage allowances.
October–November for festivals and Himalayan views, or March–April for trekking and rhododendrons. February is a quieter, affordable alternative. June–September (monsoon) is cheapest but misty.
What you pay on the Guwahati–Kathmandu route hinges on timing: book roughly 3–8 weeks ahead, stay flexible on the day of week, and you usually land the better fare. Search Guwahati to Kathmandu live to see how today's price compares to dates a month out — the gap is often 25–40 percent across IndiGo, Air India, Buddha Air (codeshares).
Last-minute Guwahati to Kathmandu fares move fast, but they're rarely the same across every airline. Run your date through the search above and FlightGPT compares real-time Guwahati Kathmandu prices across IndiGo, Air India, Buddha Air (codeshares) — so you grab the cheapest seat still open, not the first one you see.
There is currently no non-stop service between Guwahati and Kathmandu — itineraries connect via a hub, with a typical journey of ≈ 2.5–4h (1-stop or near-direct via Kolkata; some seasonal non-stop possible). Comparing hubs side by side often saves 15-30 percent. FlightGPT lets you filter by "Direct only" or compare both side by side — useful when you want the cheapest Guwahati Kathmandu ticket but are open to a layover.
Expect Guwahati–Kathmandu fares to vary by cabin, baggage and how the fare is bundled. A bare low-cost fare can end up dearer than a full-service IndiGo ticket once you add a bag and a seat. FlightGPT shows the all-in price for each option, so you're comparing like for like rather than misleading lead-in fares.
