Wi-Fi is available on Singapore Airlines flights from Kathmandu to Seattle once the aircraft is above 10,000 feet. Wi-Fi is free and unlimited for KrisFlyer members; Economy Class and Premium Economy Class members should add their membership number to the booking at least 1.5 hours before departure.

On the long-haul Singapore to Seattle sector, operated by the Airbus A350-900, Economy Class also offers a 32-inch pitch and up to 19 inches of seat width. Premium Economy Class provides a 38-inch seat pitch and up to 20 inches of seat width, giving you more room to stretch out.

Yes, Singapore Airlines provides lounge access to eligible passengers with a layover in Singapore. Your eligibility is based on your class of travel or your KrisFlyer and Star Alliance status, and it is determined by your flight leaving Singapore. Other options, like purchasing a day pass at a pay-per-use lounge, are also available.

With a layover at Singapore Changi Airport, you can make the most of your time by exploring the airport’s gardens, art installations, and quiet rest areas, or by relaxing in a lounge if you are eligible. For longer connections of around 5.5 hours or more, you may also join an official transit tour to see selected highlights of the city before returning to your gate. Shorter layovers are well spent enjoying the airport’s shopping and dining options or simply unwinding between flights. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

In Kathmandu (KTM), eligible Singapore Airlines customers may be invited to use the Horizon Lounge before departure, subject to their cabin class or frequent flyer status. During your layover at Singapore (SIN), eligible passengers can access facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or the KrisFlyer Gold Lounge, depending on their travel class and membership tier.

Kathmandu follows Nepal Time (UTC+5:45) all year. Seattle uses Pacific Time, which is UTC-8 during standard time (roughly November to March) and UTC-7 during daylight saving time (roughly March to November). This means Seattle is either 13 hours 45 minutes or 12 hours 45 minutes behind Kathmandu, depending on the month.

From Kathmandu, you will depart from Tribhuvan International Airport. In Singapore, you will transit through one of the terminals at Singapore Changi Airport used by Singapore Airlines before continuing to Seattle-Tacoma International Airport. Your exact terminal information will be shown on your e-ticket and boarding passes.

Our Kathmandu to Seattle itineraries are ticketed with a connection at Singapore Changi Airport that meets our minimum transfer time requirements. If you book both flights on a single Singapore Airlines ticket, your baggage is typically checked through and your connection is protected. We still recommend moving promptly to your next gate and checking the flight information screens on arrival.

When you travel from Kathmandu to Seattle on a single Singapore Airlines itinerary, we usually check your baggage through to Seattle at Kathmandu. At Singapore Changi Airport, our teams transfer your checked baggage to your onward flight, so you do not need to collect it during your layover. Always confirm the final tag destination on your baggage receipt at check-in.
