Your Bangkok Suvarnabhumi Airport to Kathmandu flight questions, answered

Find helpful route details based on KAYAK data, including flight times, airports, airlines and booking questions.

  • Will I need a visa to go to Kathmandu (KTM)?

    Yes, a visa is mandatory for US citizens to be allowed into the country. You can either get your visa by applying via the Nepalese Consulate or Embassy beforehand and getting approval before embarking on your journey or purchase a tourist visa upon arrival at Tribhuvan International Airport in Kathmandu. Other legal documents required for travel include your passport which must have six months or more validity remaining at the time of entry.

  • What are the transfer options from Tribhuvan International Airport to the city center?

    When transferring from KTM Airport, you can either take a taxi or use the bus service. A taxi is arguably the best option for foreigners since the drivers are very polite and will drop you off at your preferred location in the city. However, taxis are relatively costly and not ideal if you’re traveling on a budget. The cost-effective option would be using the bus service which can be accessed directly outside the airport terminal. It is worth noting that the bus service runs infrequently so be sure to check the schedule to avoid long wait times.

  • Which airlines have a good sustainability record?

    Of the airlines serving this route, Malaysia Airlines has the best sustainability record. While they haven’t yet started the use of sustainable aviation fuel, the airline is in the process of ordering new aircraft which are supposed to be more lightweight and fuel-efficient helping reduce the carbon emissions produced during every flight. As a passenger, you can also play your part by packing light to reduce weight and opting for nonstop flights to reduce your carbon footprint.

    Upgrading to first class comes with plenty of advantages although the specific details depend on each individual airline.

Your guide to booking Bangkok Suvarnabhumi Airport to Kathmandu flights

Get tips on when to book, when to fly and what to know before your trip.
  • If your dates can be flexible, aim for a Monday departure instead of Sunday. On this route, Monday flights average $440 - about $36 less than Sunday (8% savings) based on the last 12 months.
  • For the best chance at a low fare, aim to book around 10 weeks before you fly. On this route, that window historically saves about 26% versus last-minute pricing (KAYAK booking data, last 12 months).
  • If you can choose when to travel, plan your Bangkok Suvarnabhumi Airport to Kathmandu trip for January. Fares historically average $412 round-trip in that month - typically $133 less than the most expensive month, which is May (based on the last 12 months).
  • If arriving on time is high on your priority list, Thai Airways is the strongest pick on this route. 81% of Thai Airways flights from Bangkok Suvarnabhumi Airport to Kathmandu arrived on time in the past 3 months, slightly above the route's average on-time arrival rate of 73%. When flights on this route do arrive late, the average delay is 1 hour 52 minutes, so choosing a carrier with strong on-time performance can make a difference on tight schedules.
  • If you're arriving late at night and need somewhere to stay, check out these hotels close to Kathmandu Tribhuvan Airport.
    - The Everest Hotel Kathmandu
    - Vannasut Hotel and Spa
  • Thai Lion Air has the best baggage allowance for economy-class passengers so keep that in mind when booking your flight. They allow a carry-on and one checked bag for free unlike most other airlines serving this route which only have an allowance for the carry-on bag.
  • Bangkok is served by two major airports Suvarnabhumi Airport (BKK) and Don Mueang International Airport (DMK), both of which offer connections to Kathmandu. BKK is the main international airport in the city offering more connections to a range of different destinations compared to DMK. It is also worth pointing out that DMK doesn’t have nonstop flights and therefore not a good choice if you’re looking to avoid layovers.
  • When flying out of Don Mueang International Airport, Thai Lion Air is a good option to take since they have their main hub at this airport and therefore have more flight options compared to any other airline.
  • Air Asia is the only airline on this route that has onboard Wi-Fi. Although it is behind a paywall, it makes them a good option for business travelers.
  • When booking a solo ticket for your child, Malaysian Airlines is the best option. They have an unaccompanied minor service which is available for children between ages 5 and 15 ensuring that your child is taken care of for the entire trip.
