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.
  • If you have a disability that requires assistance transiting through Kathmandu Tribhuvan International Airport (KTM), you can request help from your airline. You should do this at least 48 hours before you arrive at the terminal, so that your airline has time to make suitable arrangements.
  • You can get to Kathmandu Airport from a variety of nearby locations. For instance, you can drive to the terminal from Lalitpur in about 15min, Godawari in around 35min and Budhanilkantha also in approximately 35min.

in today's time, an airline like emirates didnt serve drinks as requested, Excuse was full flight.

Very poor boarding experience with these remote gates and buses. Also these 777s bardy need a remodeling. Entertainment is a bit laggy. Food and crew is still among the better, but they seriously have to do something with these remote gates.

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

We loved flying with Emirates in business class, the staff were fabulous, going above & beyond

Very pleasant.The crews are very nice.Food were excellent.

Very pleasant.The crews are very helpful.Food are very good.

They should resume the fast track for business / first class passengers

Ove the A380 planes. Comfortable seats. Served great Indian food and Masala Chai!

Excellent comfort and entertainment. Service poor..Food average with little choice.

Qatar maybe considered one of the best ailines in the world but nowadays it is much of a muchness with the rest

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

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

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I wish the leg room was better for Economy especially for the outbound flights to India . The outbound flight to US and Qatar was good

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

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

I’ve flown with Qatar multiple times and the service has always been great. Very professional, organized, the food is delicious and plentiful, tons of entertainment.

This is not business class. This is premium economy. Total scam to sell this as business class

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

The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!

On the Boeing 777-300 aircraft there is no personalized climate control for passengers. Every time I've ever flown on this type of airplane I've been uncomfortably warm. For shorter flights (less than 5 hours) this isn't a big deal, but on longer flights where a nap is required to stay comfortable it turns into a nightmare. I love turkish airlines, but I really fo hope they upgrade their fleet. I've flown turkish air once on a newer model and had a fantastic time, so I think its the plane more than the airline.

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 pleasant except for the boarding at Istanbul and long wait for the wheel chair almost missed the flight Itambul to Dubai

During mid flight, try to get a flight attendant to help I couldn’t find one Otherwise, everything was perfect

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

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

Food was not available in the middle of the trip that is 13 hours

Everything was good and no points to complain. Food is always a tricky concept. Sometimes you like it and sometimes you don’t. Food was redundant from Kuwait City to NY-JFK.

Beautiful Flight took off on time and everything was good

Next time im going to use Kuwait air lines, hopefully

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.

It was very nice flight only suggestions to upload recent videos and English subtitles. Thanks

Wheelchair service is not available right away on Kuwait Airways

Everybody was so nice to treat me good all the workers When I came to Bangladesh there was just a little problem with the luggage but I got my luggage it took like two hours Other than that everything is good

Horrible flight. No entertainment or WiFi for a 14-hour flight. No explanations either. I’ll never fly Air India again.

Food, choice of menu and quantity were poor. Crew services were even poorer, not attending call bittons

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

Boarding at Mumbai airport was terrible, the staff had no idea how to handle it. It was chaos - and led to a delay

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.

Business class recliners and entertainment system was not working, it essentially became economy travel at the cost of business

The boarding was not in sequence. All were invited altogether. I was not secured the meal I had asked for.
