FAQs for booking Bangkok to Kathmandu flights

  • 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.

  • What are the advantages of upgrading to first class for this route?

    Upgrading to first class comes with plenty of advantages although the specific details depend on each individual airline. For instance, with Malaysia Airlines, First Class passengers get a recliner seat and extra legroom for added comfort as well as a better selection of meals and drinks to be enjoyed onboard. You also get an extra baggage allowance and access to the airline lounges during layovers.

  • What is the cheapest flight from Bangkok Suvarnabhumi Airport to Kathmandu?

KAYAK’s top tips for finding a cheap flight from Bangkok Suvarnabhumi Airport to Kathmandu

  • Looking for a cheap flight? 25% of our users found flights on this route for $224 or less one-way and $411 or less round-trip.
  • 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.

I give EVA 5 stars in every category. I enjoy this airline and it's great team of employees. I always highly recommend EVA to friends and family and everyone.

The flight was delayed going out of the gate at BKK that made it a difficult challenge to get through immigration transfer at tapei and make it to my departure on time. This appears to be a recurring issue. The flight crew and cabin crew were excellent. The food was very nice.

The boarding efficiency was good. A couple of the flight attendants did not seem in the best of moods. Overall it was a good experience.

The setting configuration of the aircraft stinks. Nobody should pay business class fares and be so uncomfortable. The design of facing fellow passengers is a brilliant nincompoop.

Entertainment is limited with a relatively old catalogue. Wi-Fi never works and the cabin and lavatory had evidence of a lot of scuff marks and temporary repairs. Nothing unsafe, but a bit tatty in places.

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

USB charging port was not working at my seat 48K.

I enjoy flying with Thai Airways, however their B788 business class configuration is quite dated. Additionally , while the service is always friendly and efficient, I’m getting tired of the same “usual suspects” when it comes to food choices. Since it was a lunchtime flight, what about some gourmet sandwiches or some type of salad dish for the main course? The entertainment options are also quite limited and this is not unique to TG, so much so that given the short duration of the flight I ended up not bothering with any entertainment. Finally, despite signs around the cabin advising wifi available, I was unable to con-net and in fact I’ve never been able to connect on any TG flight over the last year or so - what’s the go here??

Always liked Thai Airways but in the past they have been very expensive, not being a millionaire just yet, I will use cheaper airlines. Bangkok to London £370 11 hours 45 mins. Old plane but ok. Lovely ladies on board, very polite. Food was ok. Will always use them if the price is right.

Could have been better. I prefer Thai airlines only but it hasnt been reliable.

Everything was good. The red seats were a scam. Just like any other seat but red. Although they let you board earlier which was very nice.

Other than the bus wait time to off board passenger when we reached Don Muang, everything else was excellent

Very good, it would be good if payment for drinks could be accepted by card too.

Ontime, no frills, the cabin is clean, the ticket price is lower than the full-service airlines.

Paid for a meal we didn't receive. They admitted they had forgetten ours. No compensation or rectification offered. We requested if they would just give us a glass of wine instead and we would call it even. Crew advised they could not do this and to go to Air Asia counter on arrival and request a refund. Our flight didn't arrive until 2am so this was not a viable option. The crews solution was if we wanted a wine we should purchase one. I was unhappy with that suggestion considering they had already ripped us off with our meal.

Took 4 flights in 5 days 3 out of 4 left late about one hour each.

The boarding process was very poor - refueling on so rear ladder blocked. I think while boarding both ladders should be accessible so that passengers are comfortable instead of crowding through front ladder

No WiFi or movies. And the seat We’re uncomfortable. Good thing it was a short flight

It was on time! First time in a long time for Air Asia. Thank you!

Nightmare at check in because of restrictibe and unmanageable baggage rules. Very long line and slow because of these policies. Not a smart way to make $

I specifically searched for flight with checkin bags. Airfare assist website still sold tickets without check in bags and I had to pay 3 times more for my bad. Worst experience ever with untrained staff and haphazard boarding

As a frequent flyer, I was impressed with the smooth take off.

No frills means no frills... I just got on the plane and flew. That's all. Nothing more and nothing less. Or I did buy some water, they took cash only! LOL

First the flight delayed 1 hour ND then when we suppose to landing the pilot decided not to land at the chiang Mai Airport but the chiang rai airport

Pros: "This is a budget airline and they get you to where you going at good price"
Cons: "They pack you in all together even though there are open seats available and leave you there as if you've done something wrong"
Cons: "fraud on the baggge fee. Had already tried to pay on web sire, but tmdid not work. Then they charge more than twice the price at airport."

What started as a small delay at checkin ended up being a two and a half hour delay by the time the plane took off. The annoying part was that we weren’t told what the holdup was.

Offer a pillow in business class for night flight. More comfortable seats. Offer alcoholic beverages. Get flight attendants that care.

It was not possible to do an online checkin with Nepal Airlines. Apart from that, all the rest was very good : good food, friendly staff that ensure that Covid rules are respected (not always easy),…
