No airline flies nonstop from the United States to Kathmandu. Every route connects at least once, usually in the Gulf or Istanbul. From the East Coast, expect 19 to 24 hours with one stop. From the West Coast, 23 to 30. From Denver and Austin, which have no nonstop to a connecting hub, expect two stops and closer to 30.
That is the whole answer. The rest of this page is which hub suits which departure city, what the sector times are, and the practical things that go wrong.
Why there is no direct flight
Kathmandu's Tribhuvan International Airport sits in a bowl at about 1,340 metres, ringed by hills, with a single runway. It has neither the runway length and approach profile nor the traffic volume that a nonstop from North America would need. Nepal's own carriers do not operate aircraft with that range. Nothing about this is close to changing, so plan around one or two stops.
Which hub to connect through
Four hubs handle almost all US traffic to Kathmandu. They differ in how long the second leg is, which matters more than most people expect when you are already fifteen hours in.
| Hub | Code | Airlines on the Kathmandu sector | Sector time to Kathmandu |
|---|---|---|---|
| Doha | DOH | Qatar Airways, Himalaya Airlines, Nepal Airlines | About 4h 45m to 5h |
| Dubai | DXB | Emirates, flydubai, Nepal Airlines | About 4h 30m to 5h |
| Istanbul | IST | Turkish Airlines | About 7h 15m to 7h 45m |
| Delhi | DEL | Air India, IndiGo, Nepal Airlines | About 1h 45m |
| Bangkok | BKK | Thai Airways, Himalaya Airlines | About 3h 30m |
| Kuala Lumpur | KUL | Malaysia Airlines, Himalaya Airlines | About 4h 45m |
Airlines add and drop Kathmandu routes more often than they do most destinations, and some East Asian services run seasonally or have been suspended and resumed. Treat the list above as the stable core and check current schedules before you build an itinerary around any one of them.
Doha and Dubai are the workhorses for US traffic, because Qatar Airways and Emirates both fly nonstop from a long list of American cities and both put you into Kathmandu with a short second leg. Istanbul is often cheaper and puts a seven-hour flight at the end of an already long day, which is a real cost. Delhi is the shortest final sector of all at under two hours, but it means clearing a busy transfer and, for some itineraries, an Indian transit visa depending on your nationality and whether you change terminals, so check that before booking.
Times and routings by departure city
Elapsed times below are door-to-door in the air plus a normal connection, one way. They assume a sensible connection rather than an eleven-hour layover, which is what the cheapest fare will usually sell you.
| From | Code | Usual stops | Common connection | Typical elapsed time |
|---|---|---|---|---|
| New York | JFK | 1 | Doha, Dubai or Istanbul | 19 to 24 hours |
| Boston | BOS | 1 | Doha, Dubai or Istanbul | 20 to 25 hours |
| Washington | IAD | 1 | Doha, Dubai or Istanbul | 20 to 25 hours |
| Atlanta | ATL | 1 | Doha or Istanbul | 21 to 26 hours |
| Miami | MIA | 1 to 2 | Doha, Dubai or Istanbul | 22 to 28 hours |
| Chicago | ORD | 1 | Doha, Dubai or Istanbul | 21 to 26 hours |
| Dallas | DFW | 1 | Doha or Dubai | 22 to 28 hours |
| Houston | IAH | 1 | Doha, Dubai or Istanbul | 22 to 29 hours |
| Los Angeles | LAX | 1 | Doha, Dubai or Istanbul | 23 to 30 hours |
| San Francisco | SFO | 1 | Doha, Dubai or Istanbul | 23 to 29 hours |
| Seattle | SEA | 1 | Doha or Dubai | 23 to 29 hours |
| Denver | DEN | 2 | A US hub, then the Gulf or Istanbul | 25 to 32 hours |
| Austin | AUS | 2 | A US hub, then the Gulf or Istanbul | 26 to 34 hours |
Denver and Austin are the two on this list without a settled nonstop to a hub that serves Kathmandu, which is why they carry the longest journeys. If you are flying from either, price a positioning flight to Chicago, Dallas or New York separately. It is sometimes cheaper and almost always faster than whatever the through fare routes you on, though booking two separate tickets means you own the risk if the first one is late.
What it costs
Fares move constantly and any specific number on a page like this is out of date within weeks, so treat these as indicative bands rather than quotes.
From the East Coast, a return ticket typically falls somewhere around USD 900 to 1,600 in the shoulder months, and materially higher for October and November departures, which are peak trekking season and the busiest weeks of the Nepali year. From the West Coast, add roughly 10 to 20 per cent. Booking two to four months ahead usually lands you near the bottom of the band; booking inside six weeks for an October departure usually does not.
The cheapest fares are almost always the ones with a long layover or a second stop. Price the difference honestly. Saving 200 dollars to add eight hours to a journey that is already twenty-two hours long is a poor trade when you have a domestic connection to Nepalgunj the next morning.
Two other things move the number. Flying midweek rather than at a weekend is usually worth something, and flying into Kathmandu and out of Delhi, or the reverse, is occasionally much cheaper than a return on the same routing, though it adds a border crossing or an extra sector to your plans. Neither is worth contorting an itinerary for; both are worth checking once.
Baggage, and the part that catches trekkers
The international leg is generous. Most Gulf and Turkish fares to Kathmandu carry a checked allowance in the region of 30 kilograms in economy, which is more than a trekking kit needs.
The domestic legs are not. Nepali domestic flights carry a much lower free allowance, commonly around 15 kilograms plus a small piece of hand baggage, and the small aircraft serving Juphal, Jumla, Talcha and Simikot are stricter again because weight is a genuine performance constraint on those strips. Excess is charged by the kilogram and, on a full aircraft, may simply not be carried.
The practical answer is to leave whatever you do not need for the mountains in a locked bag at your Kathmandu guesthouse, which is a normal and expected request, and fly west with only what you will actually use. Bringing a large wheeled case is a mistake in any case, because no road in Western Nepal rewards one.
The time change, and why the 45 minutes matters
Nepal runs on UTC+5:45. That is 9 hours 45 minutes ahead of US Eastern Standard Time and 12 hours 45 minutes ahead of Pacific. The 45-minute offset is not a rounding error in a schedule; it catches people out when they are converting a domestic departure time from a booking confirmation. Set your phone to Kathmandu time when you board the last leg and stop doing mental arithmetic.
Practically, most itineraries land in Kathmandu in the middle of the day, having crossed most of the world overnight. Do not schedule anything for that afternoon.
Connecting onward to Western Nepal
If you are heading west rather than staying around Kathmandu and Pokhara, your international arrival is only half of the journey. Domestic flights to Nepalgunj and Dhangadhi leave from the domestic terminal at Kathmandu, and the small aircraft on to Juphal, Jumla and Simikot leave from Nepalgunj.
Never book a domestic connection on the same day as your international arrival. Mountain flights cancel for weather, bags occasionally take an extra day, and there is no later service to catch. Give yourself a night in Kathmandu first. The whole chain is set out in how to get to West Nepal.
Before you book
Sort the visa question before the ticket. US passport holders are eligible for a Nepal tourist visa on arrival, and the process is covered in our visa on arrival guide. Choose the visa duration after your itinerary is fixed, not before.
Then decide when you are going, because that decides the fare more than any booking trick does. October and November are the clearest and the most expensive. Our seasons guide explains why the western half of the country runs on a different calendar from the rest, and there is a country-level overview on our Nepal travel guide for US visitors.

Frequently Asked Questions
Are there any direct flights from the US to Nepal?
No. There is no nonstop service between any US airport and Kathmandu, and none is planned. Every itinerary connects at least once, most commonly in Doha, Dubai or Istanbul.
What is the fastest way to fly from the US to Kathmandu?
A single stop in Doha or Dubai from an East Coast city. Both put you on a four-and-a-half to five hour final sector, which keeps New York, Boston and Washington itineraries in the 19 to 24 hour range including a normal connection.
How long does it take to fly from Los Angeles to Nepal?
Typically 23 to 30 hours one way with one stop, depending on the connection. The Los Angeles to Gulf sector alone runs around 16 hours, and the onward flight to Kathmandu is roughly five.
Which airlines fly to Kathmandu?
From the Gulf and Istanbul, Qatar Airways, Emirates, flydubai and Turkish Airlines. From South and Southeast Asia, Air India, IndiGo, Thai Airways and Malaysia Airlines. Nepal Airlines and Himalaya Airlines operate the Nepali side of several of these routes. Schedules change often, so check before booking.
How much is a flight from the US to Nepal?
Indicatively, around USD 900 to 1,600 return from the East Coast outside peak season, and 10 to 20 per cent more from the West Coast. October and November departures cost noticeably more. Fares move constantly, so treat these as bands rather than quotes.
Do I need a transit visa when connecting to Nepal?
Not for Doha, Dubai or Istanbul on a normal airside connection. Connecting through Delhi can be different depending on your nationality and whether you change terminals, so check India's current transit rules before booking that routing.
Should I book a domestic Nepal flight the same day I arrive?
No. Give yourself a night in Kathmandu. Domestic and mountain flights cancel for weather, bags sometimes arrive a day late, and there is no later service to fall back on if you miss the only one.
