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.

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.

Crew were very good. Food service was a little slow and disappointing not having on demand dining and only 3 options. Amenity kits and pyjamas were excellent.

Sadly I couldn't get the food I requested as it was out. Also, if you don't want to be woken up make sure the crew knows it. My wife was woken on every service.

Three meals on a single flight is disgusting. Even if I reject them all, sleeping is impossible and all that food (especially wasted food) is just antithetical to a pleasant flight experience. People were chucking multiple abandoned trays on the floor in front of my seat.

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

Emirates need to improve the boarding process. There is no point calling for all First and Business Class passengers plus Platinum, Gold and Silver Skywards members at one time. Further to this, try channeling all these people into one entry point with no defined lines. It was chaos. The is a common issue on the Dubai to Riyadh flight. Poor effort Emirates.

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

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

Food no so good. Extra charge to much for front seats cost me £163 then other people sat near me for nothing 🤬

Boarding for business class passengers can be improved. Also, when debarking the aircraft, Economy passengers are let off first due the way the configuration of the cabin upstairs.

I am a big person and have back pain and swelling in my legs, so this was a challenging flight due to confined space. I didn't find the crew very friendly either. I will think twice before flying long distances with Qatar again, due to the lack of legroom.

I wish I knew in advance that the connecting flight was by indigo air

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

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

Excellent service. The personal adaptation of menus and the individual timing of service of them is fantastic.

Good. It would be great if comfort seats were available

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

The seats were uncomfortable. The service was poor. We bought internet for my family and myself and it didn’t work. The charger for our phone didn’t work. The service seemed like they were tired and exhausted and seemed a bit upset. It was not a good flight. Our flight from miami to Qatar was great but from Qatar to Tokyo was simply awful

The American/Hollywood movies in the entertainment system lack english subtitles, they tend to have only arabic subtitles. Coupled with the low quality airplane earphones and cabin noise, it sometimes is difficult to follow the movie dialogues.

Seats very small and unable to pre purchase internet or seat upgrades

My experience with Turkish Airlines was good. I didn’t get the meal I ordered. So I didn’t have anything to eat which was disappointing.

They changed the return flight to the next day and it interrupted the plans we had in our connecting city.

the flight was cancelled and I was rebooked twice, once 26 hours later, then another 24 hours later. In total the flight was delayed for 40 hours. Never again will I use kayak or Turkish Airlines for my travel.

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..

Paying extra for premium seats was wasted. Turkish Airlines takes 2 seats for bassinet. The lady next to me had a baby with bassinet Bassinet was in front of my seat

I had a bad experience with the Airline company. I still did not get one of my baggages. I went several times at the Airport looking for the missing luggage.

Not up to Business Class standards. Two of the three toilets were out of order. The hostesses were aware and didn’t show any responsible act to do something. Food quality was not what we expect from Turkish hospitality. Overall we were not impressed and disappointed.

I hate to have pay for my first luggage 165$ when I did my search on Kayak with 2 luggages .I don't plan to use kayak in the future and go with Turkish airlines directly

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

Very good overall.... apart from the cost of extra check ed in luggage where they charge £17 per kg, and no option to just buy an extra bag allowance (at least on the route I took)

Several seats in business class were broken. Some would not recline, others had other problems. They need to really update the seats and AV.

Overall it was good. But air planes should be upgraded.

Poor hygiene in the lavatories. Limited control of passengers who often were up standing around my seat talking loudly with their friends.

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

The plane interior was incredibly outdated. Nothing worked. My tray table was taped together (yes, TAPED!). None of the TV monitors worked. There were no buttons to turn on the overhead lights or call for a flight attendant. There was no indication of where we were or how long it would be till we got to our destination. This was a 15 hour flight btw. I was seated near the bathrooms and after a few hours on the flight, it smelled strongly of urine. It was sickening. There was only a USB charging outlet and you had to use your phone to watch movies through their WiFi. Somehow the outdated charger made it take so long to charge my devices. I paid for my seats and they definitely did a bait and switch on me. The seats I paid for were NOT the seats that I got. I will NEVER use this airline again and I highly recommend that others don't.

The trip with Air India was better than expected starting with the check-in and the Lounge. The flight was comfortable for a 1 hour flight.

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.

What a pathetic plane it was. Entertainment system didn’t work. USB port was broken. There was a hole on top of folding serving table. Broken restrooms in the middle of flight.
