Looking for cheap flights from Agartala to Kathmandu? FlightGPT compares live IXA 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 Agartala to Kathmandu non-stop tomorrow, a last-minute weekend deal or the lowest price three months out, every active Agartala-Kathmandu fare is one search away.
Kolkata (CCU) is the gateway: a 55-minute hop from Agartala, and the nearest hub with regular Kathmandu service on IndiGo, Nepal Airlines and others. The Kolkata–Kathmandu leg is short at about 1h 15m, so a well-timed connection gets you into the valley in roughly 5 hours door to door. Because both legs are brief, a through ticket is worth it to protect a tight transfer. The approach into Kathmandu, ringed by Himalayan foothills, is one of the most scenic descents in the region.
From Kolkata, IndiGo offers the most frequencies to Kathmandu, with Nepal Airlines (the flag carrier) and Buddha Air also operating. From Agartala the feeder is typically IndiGo, so an all-IndiGo IXA–CCU–KTM itinerary is convenient for through baggage and a single booking. If you want to combine the trip with Nepal's domestic scenic flights to Pokhara or the Everest region, Buddha Air and Yeti Airlines handle those onward sectors. Compare timings to minimise the Kolkata layover.
Combined return economy fares from Agartala to Kathmandu typically run ₹18,000–₹34,000 including the feeder, depending on season and lead time. The cheapest months are the summer monsoon (June–August) and January, away from the October–November and March–April trekking peaks when demand and prices climb. Booking 6–8 weeks ahead and flying mid-week helps. A fare alert can catch IndiGo or Nepal Airlines sales worth ₹4,000–₹7,000 off the round-trip, particularly in the low season.
This is the great advantage: Indian passport holders do not need a visa for Nepal and can stay and work freely under the bilateral arrangement. You don't even strictly need a passport for land travel, but for flying you should carry a valid passport or a voter ID; a passport is strongly recommended for air entry and smoother immigration. There's no visa fee or paperwork. Carry some Indian rupees (smaller notes are widely accepted) and a return ticket. See our visa guide for accepted ID details.
Kathmandu's Tribhuvan International Airport (KTM) sits just 6 km east of the city centre, so a taxi to Thamel or Durbar Marg takes only 20–30 minutes depending on traffic. The airport is compact and can get congested, especially in trekking season, so allow buffer time on departure. Prepaid taxi counters give fair fares; ride-hailing apps also operate. The valley sits at about 1,400 m altitude, so most visitors feel fine, but those heading higher for trekking should acclimatise gradually.
Nepal's prime seasons are autumn (October–November) and spring (March–April), with clear mountain views, daytime temperatures of 18–25°C in the valley, and the best trekking conditions — also the busiest and priciest. The June–September monsoon brings rain, clouds and the lowest fares, while winter (December–January) is cold but clear, great for valley sightseeing. For a balance of views and lower prices, late September or early December can work well. Book trekking-season flights well ahead.
IndiGo and Nepal Airlines international economy fares typically include 20–30 kg of checked baggage, but the Agartala–Kolkata feeder may cap at 15 kg, so a through international ticket inherits the larger allowance — useful if you carry trekking gear. Onward scenic flights have tight weight limits, so pack light for those. Watch out for occasional weather delays into Kathmandu in monsoon. For another short regional hop from the northeast, compare our Agartala to Dhaka guide.

Kathmandu is just 15 minutes ahead of India (UTC+5:45 versus IST UTC+5:30), the only such 45-minute-offset zone in the region — effectively no jet lag.
Tribhuvan International is only about 6 km from central Kathmandu; a taxi to Thamel takes just 20–30 minutes depending on traffic.
October–November and March–April offer the clearest mountain views and best trekking at 18–25°C in the valley, but fares are lowest in the June–September monsoon.
