Honestly, the flight from Delhi to Kathmandu is a bit of a psychological trick. You’re in the air for barely 90 minutes. You spend more time navigating the security line at Terminal 3 in Delhi than you do actually crossing the Himalayas. Yet, for such a short hop, the price swings can be absolutely wild. One day you’re looking at a $55 steal, and the next, the algorithm decides your seat is worth as much as a flight to Dubai.
It’s a busy corridor. Business travelers, trekkers heading for the Everest region, and families visiting relatives keep these planes packed. If you're planning to book flights from delhi to kathmandu nepal, don't just click the first "deal" you see on a search engine. There’s a specific rhythm to this route that most people miss.
The Airline Tug-of-War: Who Should You Actually Fly?
You basically have four main choices for direct flights. Each has its own vibe, and "cheapest" doesn't always mean "best value" when you factor in the baggage games.
IndiGo is the heavy hitter here. They run multiple daily flights and usually have the lowest base fare—often starting around ₹4,500 to ₹5,000 ($55-$60) if you book a few weeks out. But watch out. Their "Lite" fares don’t include checked bags. If you’re a trekker with a 15kg rucksack, that "cheap" ticket will balloon at checkout.

Air India is the old reliable, though "reliable" is a strong word in aviation. They typically offer a 20kg or 25kg checked baggage allowance even on their basic Economy tickets. If you have heavy bags, Air India often ends up being cheaper than IndiGo after you add baggage fees. Plus, you get a meal. It might just be a sandwich and a juice box, but on a 1-hour flight, it’s a nice perk.
Then you have Nepal Airlines. It’s the national flag carrier and flying with them feels like you've already stepped into Nepal. Their schedules can be... let's say fluid. Delays aren't uncommon. However, they sometimes have the best last-minute availability when the big Indian carriers are sold out.
A Quick Reality Check on Costs
| Airline | Typical Price (One-Way) | Baggage Inclusion |
|---|---|---|
| IndiGo | ₹4,800 - ₹7,500 | 7kg Cabin Only (Base) |
| Air India | ₹5,500 - ₹9,000 | 20kg-25kg Checked |
| Nepal Airlines | ₹6,000 - ₹8,500 | 20kg Checked |
| Bhutan Airlines | ₹7,500+ | 30kg Checked |
The Visa Question (It’s Simpler Than You Think)
If you’re an Indian citizen, you don’t need a visa. Period. You don't even technically need a passport if you have a valid Voter ID card issued by the Election Commission of India. But honestly? Just take your passport. It makes the immigration process at Tribhuvan International Airport (KTM) so much smoother.

For everyone else—Americans, Brits, Europeans—you’ll need a visa. You can get a Visa on Arrival at Kathmandu, but the lines are legendary. Do yourself a favor and fill out the online pre-arrival form before you even leave Delhi. It’ll save you an hour of standing in front of a glitchy kiosk while your luggage circles the belt downstairs.
Timing the Himalayan View
This is the expert tip nobody tells you: Sit on the right side of the plane. When you’re flying from Delhi to Kathmandu, the Himalayan range is to the north. That means if you’re in a window seat on the right (usually row F), you’ll get a front-row seat to the snow-capped peaks as you descend into the valley. If you’re flying back from Kathmandu to Delhi, sit on the left.
Also, try to book the earliest flight possible. The 6:00 AM or 7:00 AM departures are much less likely to be delayed by the afternoon winds and fog that frequently shut down Kathmandu's single runway.

The "Secret" Layover Strategy
Sometimes, direct flights get weirdly expensive—like $200 for a one-way trip. If that happens, look at SriLankan Airlines or Air India Express with a stop. It sounds insane to fly south to Colombo just to go back north to Nepal, but occasionally those long-haul carriers drop "distressed inventory" prices that beat the direct LCCs.
Only do this if you have time to kill and want to save $100. Otherwise, the 1.5-hour direct flight is king.
Getting from KTM to the City
Once you land in Kathmandu, the chaos begins. The airport is small, loud, and a bit overwhelming. Prepaid taxis are available just outside the arrival hall. They’ll charge you a fixed rate (usually around 800-1000 NPR) to get to Thamel.
If you want to feel like a local, download Pathao or InDrive. These are the Uber/Ola equivalents in Nepal. They are significantly cheaper than the airport taxis, though you might have to walk a few hundred meters outside the airport gate to meet your driver.
Actionable Next Steps for Your Trip:
- Check the baggage rules: If you're carrying trekking gear, Air India is almost always a better deal than IndiGo.
- Book 3 weeks out: Prices on this route don't usually drop last minute; they only climb.
- Pick the right seat: Right side (Seats A/B/C are on the left, D/E/F are on the right) for the mountain views.
- Carry Cash: Even though Delhi is going cashless, Kathmandu still runs on paper. Carry some Indian Rupees (₹200 and ₹500 notes are now widely accepted again, but check the latest local regulations) or US Dollars for your initial expenses.
