Airlines & nonstop vs connecting on Delhi–Kathmandu
This is a dense non-stop market. IndiGo (6E) typically flies the most daily frequencies and is usually the cheapest. Air India offers full-service non-stops with meals and checked bags included (note: Vistara has fully merged into Air India, so it is the single Indian full-service carrier here). Nepal Airlines, Nepal's flag carrier, adds a full-service option. Between them they operate roughly 8–12 non-stops a day. You don't need a connection on this route — there are plenty of direct flights spread across the day.
Flight time, distance & routing
The non-stop block time is about 1 hour 50 minutes over roughly 1,000 km. The routing heads east across the north Indian plains toward the Himalayan foothills, with a scenic descent into the Kathmandu valley — on clear mornings, right-side window seats can catch Himalayan peaks. Kathmandu's Tribhuvan International Airport sits in a bowl-shaped valley, so approaches can be bumpy and occasionally subject to weather or congestion delays. Nepal is only 15 minutes ahead of India, so there's effectively no jet lag.
Best time to book & seasonal fare patterns
Peak season is October–November (post-monsoon clear skies and trekking season) and around major festivals (Dashain, Tihar) and the spring trekking window (March–April), when fares climb. The monsoon (June–August) and deep winter are quieter and cheaper, though mountain views and trekking are limited. Because frequencies are high and the hop is short, you can often find good fares 2–4 weeks out outside peak dates — but for October and festival travel, book earlier. Check live fares in the FlightGPT search.
How to get the DEL–KTM fare cheaper
With three airlines and many daily flights, comparison pays off: IndiGo is usually lowest for a no-frills hop, while Air India and Nepal Airlines bundle meals and baggage that can be better value if you'd buy extras anyway. Early-morning and mid-day departures are often cheaper than prime evening slots. Travelling cabin-only on IndiGo and skipping add-ons keeps it cheapest. Browse other India–subcontinent hops on the routes hub, and always confirm live fares in the FlightGPT search before booking.
Airports & terminals
In Delhi, IndiGo, Air India and Nepal Airlines depart from Indira Gandhi International, Terminal 3 (T3) for international flights — allow about 2–2.5 hours, as it's still an international departure with immigration. Kathmandu Tribhuvan (KTM) has a compact international terminal; arrivals are simple for Indians since no visa is required — just immigration with your passport or Voter ID. The airport is about 6 km from Thamel, the main tourist hub; prepaid taxis and hotel pickups are the easiest way in.
Baggage
On IndiGo's international Delhi–Kathmandu fares, checked allowance is typically around 20–30 kg depending on the fare, with extra weight charged — see the IndiGo baggage guide. Air India full-service economy generally includes a checked allowance and meals; see the Air India baggage guide. Nepal Airlines includes a checked allowance too. If you're carrying trekking gear, confirm the exact figure for your fare and pre-purchase any excess.
Visa for Indian passport holders
Indians do not need a visa for Nepal. You can enter visa-free for any length of stay using a valid Indian passport or an Election Commission Voter ID (EPIC). Note that an Aadhaar card is not accepted for entry. A 2026 rule to be aware of: if you plan to travel onward from Nepal to a third country, you may be required to obtain a No Objection Certificate from the Indian Embassy in Kathmandu — verify this if your trip continues beyond Nepal. For a hassle-free trip, carry your passport. See our visa guide for Indian travellers.
Domestic onward connections in Nepal
Kathmandu is the hub for Nepal's domestic network — from KTM you can connect to Pokhara (gateway to the Annapurna region), Lukla (for Everest Base Camp treks), Bharatpur (for Chitwan National Park) and Bhairahawa (for Lumbini). Domestic carriers such as Buddha Air and Yeti Airlines fly these turboprop routes; note Buddha Air operates within Nepal (and a few India sectors like Varanasi and Kolkata) but not Delhi–Kathmandu. Allow a comfortable connection in Kathmandu, as mountain weather can disrupt domestic schedules.
Practical travel tips
Indian rupees are widely accepted in Nepal, but note that INR 500 and 2000 notes are restricted — carry smaller denominations or use Nepali rupees. There's effectively no jet lag (Nepal is 15 minutes ahead). Mornings offer the clearest mountain views, so book early flights in trekking season. Altitude in Kathmandu (about 1,400 m) is mild, but plan acclimatisation if heading higher. For treks, arrange permits (TIMS, national-park entry) in Kathmandu before flying domestic.
Why visit Kathmandu
Kathmandu is a living museum of temples and culture: the sacred Pashupatinath, the giant Boudhanath stupa, Swayambhunath (the monkey temple) and the medieval Durbar Squares of Kathmandu, Patan and Bhaktapur. It's the launchpad for the world's greatest trekking — Everest, Annapurna and Langtang — and for spiritual journeys to Lumbini, the Buddha's birthplace. With cheap flights, no visa for Indians and near-zero time difference, it's one of the easiest and most rewarding short overseas trips from Delhi.
