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.

Extremely uncomfortable seats with very little cushioning, unable to recline enough to sleep comfortably on this 13 hour overnight flight. My body was in pain by the end.

Extremely uncomfortable seats with very little cushioning, unable to recline enough to sleep comfortably on this 13 hour overnight flight. My body was in pain by the end.

First off, it wasn't clear that my first flight was to be operated by IndiGO. While the flight itself was fine, this meant that my whole initial check in where I would've properly verified my seating on my Qatar flight/requested an upgrade was impeded by the fact that I had to check in with IndiGO. They said I would separately have to go to Qatar counter to deal with second flight leg issues, which was impossible given how long the check in took/no time available to do so.

Qatar Airways is an excellent service provider. The crew members were attentive and helpful. The aircraft was very clean. This was the longest leg of our journey, so it would have been nice to have more leg room for comfort. We appreciated the crew's service of four hot meals to all of us during this long flight. Also, it was helpful that the crew asked us to keep the window shades down for the entire journey, allowing the environment to get lots of rest during the trip. For families traveling with little children, this was helpful to them to keep them settled.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

In the business class it was everything wonderful. However in the economy is a hell. BTW. When I asked to search for tickets, I ordered business and I was offered options with economy, that was not clear in the order, so I could've acted faster to rectify it.

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.

It would help id flight crew were not rude and showed some courtesy. They were shouting at passengers and yelling instructions as if we were school children at lunch cafeteria!!

I always fly with Qatar air and you are the best. Keep up the good wor, after travelling with Qatar Air More than 80 times, you never offer to upgrade me.but it happened to my friend companion some time. Any how i still enjoying travelling with Qatar air and wait one day to upgrade me too. Best Regards

You are the best, keep up the good work. Thank you for allowing me and my family to fly with comfort.i am waiting for upgrade some day. Thanks again

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.

The web check in doesn’t work. Had to wait 10 minutes on the counter for them to figure out boarding. I understand AI Express doesn’t have a practice to offer food to everyone in the business class. The flight attendant asks for name (not sure why she doesn’t know it especially with only 8 passengers in the business class) to figure out whether or not they should serve food. KAYAK should sell AI Express tickets separately, not as part of AI. Neither the experience close to AI, the Maharaja points also don’t get awarded despite Express being part of AI.

The plane was very dated with the worst entertainment system i have seen in 30 years. Flight attendants were responsive.

They rescheduled flight..no customer care to even reach or accommodate

Food was below par Quality and None of the Entertainment systems were Working ..and we were unable to turn it off.. Due to the glare we couldn't even sleep for the entire duration of the flight ..

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

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.
