Flight Deals from Seattle to Kathmandu from $830

Seattle to Kathmandu is about 6,970 miles, and there is no scheduled nonstop service, so the trip requires a connection.

Methodology

Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.

There are no non-stop flights from Seattle to Kathmandu. The shortest connecting routing is Cathay Pacific via Hong Kong, with a total trip time of 21 hours 15 minutes — the 14-hour leg to Hong Kong, a 2-hour-10-minute layover, and a 5-hour-5-minute onward leg to Kathmandu. Turkish Airlines connects via Istanbul at 22 hours 35 minutes, and Emirates connects via Dubai at 27 hours 45 minutes.

Methodology

Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.

Getting from Tribhuvan International Airport to central Kathmandu is easiest by taxi or pre-booked private transfer, which takes about 15 minutes and costs roughly $6–$10 during the day, with pre-paid taxis available around the clock. Local buses and microbuses, including the Sajha Yatayat service, offer the only public transit option and cost as little as NPR 15–25, but they run infrequently, can be chaotic, and aren't ideal for first-time visitors. Car rental is available through agencies like Avis, though it's not a common choice for the short 5 km trip into the city. Taxis are the most-used and most reliable option for most travelers, while the bus is best for budget-conscious visitors. Ride-hailing apps are not widely established at the airport, so taxis and private transfers remain the practical choices.

Overnight red-eye service from Seattle to Kathmandu is available only as a connecting itinerary, with no nonstop red-eyes. Qatar Airways departs Seattle at 4:25 PM on the overnight leg to Doha, arriving at 5:40 PM, then connects in Doha to Kathmandu after a long layover.

Methodology

Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.

There's no nonstop service from Seattle to Kathmandu; the common routings are one-stop connections. Cathay Pacific via Hong Kong is the quickest, with a total trip time around 21 hours 15 minutes. Turkish Airlines connects via Istanbul, Emirates via Dubai (with Nepal Airlines on the final leg), Qatar Airways via Doha, and Korean Air via Seoul. Qatar Airways offers the most frequent one-stop patterns in the sample, while the others each show a single daily connection.

Kathmandu has one main airport, Tribhuvan International Airport. It is located about 6 km east of the city centre and serves all international and domestic flights.

The Link light rail is the most popular and economical way to reach Seattle-Tacoma International Airport from downtown Seattle, taking about 38 minutes to the SeaTac/Airport Station with trains every 8-10 minutes. Taxis, ride-share services like Uber and Lyft, and shuttle buses offer door-to-door convenience from the 3rd floor of the parking garage, while driving yourself is possible but parking downtown can be expensive. For the fastest trip, a taxi or ride-share typically takes 20-30 minutes depending on traffic, though the light rail is often the most reliable choice during peak hours.

Kathmandu's Tribhuvan International Airport has no on-site or terminal-connected hotel, so you'll need to look to nearby properties for a proper bed. Hotel Black Diamond and Airport Diana Hotel are both about 0.2 miles (0.3 km) from the airport, while Apex Business Hotel and Airport Himalaya Boutique Hotel sit roughly 0.3 miles (0.5 km) away. Sleeping inside the terminal isn't really an option either since the airport closes nightly from about 12:30 AM to 6:30 AM and there are no dedicated rest zones or cots.

There is no nonstop service from Seattle to Kathmandu; connecting itineraries are operated by Qatar Airways, Cathay Pacific, Emirates, Turkish Airlines, and Korean Air. Qatar Airways flies the most, using a Boeing 777-300ER on the long leg from Seattle to Doha with a Boeing 787-8 or 787-9 onward to Kathmandu, while Cathay Pacific uses an Airbus A350-900 to Hong Kong and an A330-300 to Kathmandu. Emirates flies a Boeing 777-300ER to Dubai with an A330-200 on the final leg, Turkish Airlines uses an A350-900 to Istanbul with an A330-300 to Kathmandu, and Korean Air operates a Boeing 787-10 to Seoul with a 787-9 to Kathmandu.

Methodology

Aircraft types come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.

Flights from Seattle to Kathmandu are connecting-only, with no nonstop service; the alliances represented on the route are oneworld (via Cathay Pacific, and Qatar Airways), Star Alliance (via Turkish Airlines), and SkyTeam (via Korean Air). Emirates, which connects through Dubai, belongs to no alliance, as does Nepal Airlines on the final leg. Other alliances may also serve the route via connections.
