Kathmandu is closer to Dibrugarh than Delhi is, but Mohanbari airport (DIB) has no international flights, so you must route through a hub. Kolkata (CCU) is the natural gateway at a 1h 20m feeder, with onward IndiGo and Nepal Airlines service. Delhi (DEL) has more KTM frequencies but a longer 2h 40m feeder. Most Assam travellers self-transfer through Kolkata for the shortest practical journey to the Himalayan capital.
A DIB–CCU–KTM itinerary totals roughly 5–6 hours including a layover, the Kolkata–Kathmandu leg lasting about 1h 30m. DIB–DEL–KTM runs longer at 7–8 hours but offers more departures, with the Delhi–Kathmandu leg about 1h 45m. Since no visa is needed, self-transfer is low-stress, but still allow 2 hours in Kolkata for the international re-check-in and security.
IndiGo offers the most frequent and competitively priced India–Kathmandu service from both Kolkata and Delhi. Nepal Airlines, the national carrier, and Air India also serve KTM. For the Dibrugarh feeder you will fly IndiGo or Alliance Air. Pairing a budget feeder with IndiGo on the international leg keeps the whole trip affordable and is the common choice for Assam tourists and pilgrims heading to Pashupatinath.
Economy round-trips from the Assam region to Kathmandu typically run ₹20,000–₹36,000, rising toward ₹44,000 during the October–November and March–April trekking peaks. The cheapest fares appear in the monsoon months of June–August and in January. Book 3–5 weeks ahead and stay flexible on Kolkata layover timing to lock the lower band, since Himalayan-season demand pushes prices up quickly.
Indian citizens do not need a visa or passport for Nepal — a valid passport or a government photo ID such as a voter ID or Aadhaar (for adults) is accepted, though a passport is strongly recommended for air travel and smoother checks. There is no entry fee. This makes Nepal the lowest-friction overseas trip from Assam. Our visa guide lists the accepted ID documents in detail.
October–November and March–April offer clear mountain views and ideal trekking weather (15–25°C in the valley), while June–September brings monsoon clouds. Kathmandu sits at about 1,400 m altitude, so pack a light jacket for cool evenings. Tribhuvan International (KTM) is roughly 6 km from Thamel, a 20–40 minute drive depending on traffic. IndiGo economy generally allows 20 kg checked plus 7 kg cabin.
Indian rupees are widely accepted in Nepal, but carry smaller denominations since ₹2,000 notes can be refused; the exchange rate is roughly 1.6 NPR per INR. The 15-minute time gap is minor but real. For trekking permits beyond Kathmandu, arrange TIMS cards locally. If self-connecting in Kolkata, leave at least 2 hours, and keep a passport handy even though IDs are accepted, as airlines often prefer it.
