KAYAK’s top tips for finding a cheap flight from Kathmandu to London Heathrow Airport

  • If you can’t find an airline offering direct service from Kathmandu Tribhuvan International Airport (KTN) destined for London Heathrow Airport (LHR), there are several of them that provide one-stop service to London. Etihad Airways, Emirates and Qatar Airways are three such airlines, which provide multiple one-stop flights along this air route.
  • Kathmandu Tribhuvan Airport is the principal gateway to the city as well as being the only international airport in Nepal. Kathmandu Tribhuvan Airport has two terminals, one for domestic flights and another for international flights, and is located less than 4 miles east of Kathmandu city centre.
  • There is a parking facility in front of the international terminal building at Kathmandu Tribhuvan Airport, which is very convenient if you’re being dropped off by a friend, relative or taxi. The parking garage has space for over 250 vehicles, including pre-paid taxis, private and VIP vehicles and government transport.
  • There are no trains running from Kathmandu city centre to Kathmandu Tribhuvan Airport, so take a taxi or use hotel airport shuttle transport if the service is provided. There are city buses that stop at the airport’s entrance, and while this is the most affordable option, airport bypass buses make frequent stops along the way so travel times could be lengthy.
  • If you are having difficulty negotiating the environs of Kathmandu Tribhuvan Airport, there is an Information Desk where you can enquire about flight schedules, terminals and the locations of airport services and facilities. The Information Desk is located landside of the main terminal building.

Very bad service and food variety will never come back again

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

I had issue with my boarding pass. When I arrived in London Gatwick Airport. My e-ticket wasn't scanning and had to do a lot of back and forth with Air Transit I order to board my flight, which I almost missed as a result of this.

Everything was so smooth. It could be just a better temperature in the plane; it was a little cold.

The food and drinks were below the normal standard we expect from Turkish Airlines. On a 4 hour flight we received 1 drinks service and 1 food service, the latter was a cheese omlete, which is well below what we have received in the past, such a shame we always recommend this airline..

What I did not like was that the airline changed my seat in Bodrum to one that was not in business class. Up until that moment I was in seat 1A. Then suddenly they told me I was in seat 1K and my "tablet was not working". - meaning my tv screen. I said that was not ok and they said go tell them in Istanbul. Each Turkish Air rep that I consulted told me there were no available seats in Business class. Finally I talked to the 4 airline representatives outside the lounge. When I talked to a woman and explained I wanted to change my seat back to what I had, A lady consulted something, asked me if I signed anything, then turned to a man nearby and spoke in Turkish. The man consulted someone and spoke in Turkish to the woman. Then she said my seat was now A1. Why was my seat changed out of business class in the first place? What would have happened if I had not talked to someone at the lounge? I am totally confused.

It was great except my luggage was C severely damaged over i picked it up off the carousel in London. . A suit case that had been used once does no longer have the use of the extendable arm as it’s broken

A fairly standard 2/2 configuration. Boeing 787-9 is modern but the amenities chosen by Turkish for their seats are slightly limited - no in-seat charging, for example. Otherwise, a good flight.

Not sure how they are rated best airline in Europe. If they are the best; then I worry about the overall airline standards of European airlines. Seats were very uncomfortable and almost closer to budget airlines in terms of comfort. A sore bottom after a long haul flight ruins your holiday at the start. Check in process was okay. Staff/crew was good - interactions ranged from pleasant to borderline rude (depending on the particular individual).

Check-in was a mess, transfer flights were sepersted so no one could sit with their company. Some tickets were closed to online check-in without notice hand luggage allowances were not checked so oberhead bins were already full halfway through boarding.

The flight was delayed by 1.5 hours without much explanation and they ran out of complimentary bag for inflight comfort. Would like to know if i can can get compensation

You can understand why Turkish Airlines are rated so highly; the whole experience was really good indeed. Aircraft itself was spacious, comfortable, and very well appointed. The crew were great, friendly and helpful. All round a great service and good value. Istanbul airport is also a remarkable place. Highly recommended.

Same as already mentioned. This was more comforting as I got my aisle seat for my knee.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

Very efficient and professional staff. Food was good and so was entertainment selection.

Initial booking was confusing and had to get new CC issued.

It was excellent in all respects. I don’t think it needs any improvement

riding in first class, you don't expect every time you order your dinner or breakfast that the first thing the stewardess says is Let me see if we have any left. Also, the food selection was not great: 3 of 4 entrees had mushrooms and I dont eat mushrooms, the 4th item was 'let me see if we have any left' and this was within 30 mins of entering the flight! Same experience level, it didn't feel first class this round.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

I like is everything is good seets are little uncomfortable during the long flight ✈️ Doha to us , luggage 🧳 came too late overall very nice thank you for all

Privacy and comfort of the QSuites is wonderful. The boarding process in Doha is cumbersome and confusing. As transfer passengers, traveling in Business Class, we went through security twice, including one at the gate requiring all electronic devices removed from bags and watches off, which are a great way to lose belongings as a few hundred people rush through to board the plane.

The screen was not clean.It had stains of previous customer .Also the toilets..My daughter got urine infection. Not happy with the cleanliness of aircraft.Also requested multiple time hot beverages but not served at all sighting disturbances. Request on behalf of every passenger please sanitize and clean as we stay for 15 plus hours..

Kuwait Airways is one of the airlines that has entered into competition with other carriers and has become distinguished in the quality of its services. However, it still requires further development, particularly in its digital services related to airport operations and in-flight entertainment. I believe that over the coming years, Kuwait Airways may reach a highly competitive level in terms of the services it provides.

I do not have any issue after travelling but not able to return back to Newyork because my flight is cancelled. Requested to refund my full amount.

Food is terrible, service is not good. Staff were not personable and rushed food service.

Boarding /lounge :Chaotic boarding , business /first class had a dedicated line but it was upto to the passenger to figure out and use those lines .Oasis lounge is clean but tiny so it felt over crowded . Neither the food nor amenities felt business/first class . Cabin and tech : 2-2-2 configuration needs to go . Leg space is cramped , headsets didn’t work . WIFI does exist or didn’t work on the entire 20 hour journey . Food and crew : Preordered “Hindu Non vegetarian” meal , crew was clueless , they didn’t even bother to ask if they weren’t sure what that meant . Served mediocre vegetarian food though menu had chicken /lamb options . In short , worst business class experience of all the airlines I flew to date . Not sure if there is one area they compete in let alone excel … avoid if you can .

Beautiful Flight took off on time and everything was good

Comfortable seats. Be aware there is no alcohol on this airline.

Seats were comfortable. Be aware there is no alcohol on this airline.

Every thing was very food except the meal. It was a sandwich of something like a beef kebab. It was really bad in terms of hardness as well as taste. We were a family of 7 persons non of us could eat it his sandwich. Cake was good.

Wheelchair service is not available right away on Kuwait Airways

Not much on entertainment, food was good but not delicious, flight was on time

very run down aircraft. seat tilted. the mobile / magazine holder was broken. The entertainment screen was not working. The crew was good, polite and helpful

It was far better than what others had led me to expect. I would fly with them again. Don't expect all features of the entertainment system to work.

Terrible. Air India canceled my flight out of Kathmandu because of airport constructions but did not tell me. They should not be selling night flights out of Kathmandu right now that they know they will not honor. The staff was terrible and not helpful with my rebooking or compensating me.

Flight leg to and from IAD/Delhi was good. The leg to and from Delhi/KTM was terrible.

Other than the inflight video screen freezing for about four hours everything else was brilliant.

The flight was dirty. The screens were not working and people were restless. Food and staff was okay.

BAD experience. Entertainment system was not working and most of the passengers had this issue. Staff was not helpful. Meal was yuck. Bad old flights.

Their security process is excessive. We were checked when we got off our incoming plane, at the gate and up the stairs when boarding the plane. Come on.

Interment is zero tv wasn’t work phone charger plug doesn’t work moves doesn’t work

It was my elderly parents travel with my uncle and aunt who were over 80 yrs So i have boarded all these four passenger and the lady could not give us all four seats together even though i have check in them all at once. Then the wheel chair service was one of its worse kind. The wheel chair service guys left my parents once they reach to security check. And same issued of wheel chair happened at the Delhi airport, No one is there to help them for the wheel chair assistance. It was ridiculous and have to beg to the staff there for the assistance. Its not because of Air India I have booked there ticket but it was because of most of the passengers are Indian and in case they need help some one can help and understand them. It is our Compulsion. Otherwise we would choose different path.
