FAQs - booking Sri Lanka flights

  • Can I fly directly from London to Sri Lanka?

    SriLankan Airlines flies directly from London to Sri Lanka daily. These flights leave in the mid evening from Heathrow Airport and land at Colombo International Airport after an overnight flight of about 10h 45min. The fastest one-stop flight is on Qatar Airways, which flies between the same airports, stopping in Doha on the way, taking about 12h 30min.

  • How do I get from Colombo Airport to the city centre?

    Colombo Airport is some way outside the centre of Colombo. You can even catch a 15min Cinnamon Air single-prop Cessna flight there, but that’s probably overkill. Instead, board a Sri Lanka Transport Board bus that leaves every 30min from Katunayake Airport Bus Station, taking about 45min to central Colombo. Otherwise it’s about a 25min drive.

  • What other towns or cities can I reach from Colombo?

    Colombo is roughly in the middle of Sri Lanka’s east coast. To explore more of the island, you can travel inland to Kandy, another of the country’s main cities, pretty much in the centre of the island. To the south, you can visit Galle and Matale, both coastal resorts. Towns worth visiting on the west coast of Sri Lanka include Batticaloa and Kalmunai.

  • Are there child seat laws in Sri Lanka?

    There aren’t any official laws regarding child seats in Sri Lanka, but the government together with private road safety organisations has a strong public safety initiative encouraging people to use them. It can sometimes be difficult to get a child seat on short notice if you hire a car on arrival, so it’s best to book one in advance.

  • Will I need a visa to visit Sri Lanka?

    As a UK citizen, you won’t need a visa to enter Sri Lanka, but you will require an Electronic Travel Authorisation (ETA). It’s best to apply for this online before you leave to avoid unforeseen delays on arrival. The ETA allows you to enter Sri Lanka twice, for up to 30 days in total.

  • How does KAYAK find such low prices on flights from London to Sri Lanka?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from London to Sri Lanka.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from London to Sri Lanka?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from London to Sri Lanka is likely to change within 7 days, so travellers know whether to wait or book now.

  • What is the Hacker Fare option on flights from London to Sri Lanka?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional return ticket. You could then fly from London to Sri Lanka with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from London to Sri Lanka?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from London to Sri Lanka up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

Top tips for finding a cheap flight from London to Sri Lanka

  • You can leave from Heathrow Airport (LHR) or Gatwick Airport (LGW), depending on whether you’re closer to the west or south of the Greater London Metropolitan area.
  • To reduce your carbon emissions on your flight to Sri Lanka, opt for the three-stop flight from Gatwick, flying on a combination of easyJet, Turkish Airlines and Oman Air.
  • If you’re waiting for an onward flight at Heathrow, you can hire a sleeping cabin at the airport to catch up on some shut-eye before boarding your next plane.
  • After your long flight, you can enjoy a recuperative massage in the airport spa and salon when you arrive at Colombo Bandaranaike International Airport (CMB), for a small fee .
  • Colombo Airport is the home base for SriLankan Airlines, so if you fly on this carrier, you get access to Serendiva Lounge at Colombo Airport, with premium food and drink, showers and spa services.
  • The Pinnawalla Elephant Sanctuary is one of the most significant of Sri Lanka’s natural attractions. You can reach it in about 1h 30min by hire car or taxi, or on a Sri Lankan Railways train.

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

Crews are very rude and unhelpful. Cramped seats in economy. Foods are useless

Lovely aircraft and I flight entertainment. Good leg room. Full flight crew struggled a bit

Food not good as good as last time flew with them

Seats very uncomfortable, impossible to sleep. Food average, bakery items not fresh. Pockets in seats not large enough to hold a book and a few other items. Cabin temperature too cold, even with blanket. Good selection of movies. Other than that 12 hours of torture!

Flight changed to Oman air under one alliance . Seating , entertainment was not up to the quality of QR . Hope my trip back from cmb Doh will operate a QR flight instead of any other under one alliance .

The crews have been excellent I feel like they go an extra mile to make my trip the most comfortable one and they do it cheerfully. I left my usb cable in the plane and two of the crews found me and gave it to me. Now where in the woods can you get such service I asked them to give you their names: Khaoula,Bhagwan,Juliet’s,Pam’s and two more from ATL to Doha trip. Yeah get free commercial fr me Fly Qatar whenever and wherever you fly and you will never be disappointed!!!

Maybe some more information as to why the flight got delayed I understand may be tell your customers that missiles were fired at a specific airport wouldn't be reassuring to the customers and would cause mayhem but something like recent events have cause a delay on your flight or smth

Air hostesses were great. Food was good. Flat bed is not that flat or comfortable.

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

1 hour delay meant missed my connecting flight and 1st day of holiday

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

It was an old plane with seats not comfortable and with little space for the legs. I must say that the previous flight I had was amazing on a very comfortable new plane

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

Very very bad service very tight seats never ever flying with Etihad again

It feels like the seat did not have any cushion just plywood. The seats are so compact that I could not even move at all and I am slim. Just imagine someone else. Singapore Air and Emirates are far far better than this. Do not even travel for free. For a 12 hour flight sitting on a plywood is horrible experience and on top of that the person at checking counter at NY was worst and rude. Plus they charge arms and leg for everything. I think they would also start charging for belts and oxygen also soon. First and last time flying with Ethiad.

Too many carryon bags with size of checking bags. Because of that space was not there to put carry on backpacks.

Nice crew.flight delay fromBKK for some ground prep issue I guess, crew serve well to guest, and respect to guest as well. As usual AC is old,and nt much comert in compare to other rehional airliners.other than that.all good

Flight was on time.food is as usual good.Aircraft is old.old A320, seats aithout any display.crew serve well

When flying from Indian Sector, should be more prepared with Indian food

KAYAK Real time status update is not accurate.the flight inbound rejected and go around.and came back and land. Delay abt 30 min.still shows ontime.track ur self if u wana real time.and cabin crew s are nicer. Aircraft is jst ok.old airplane.and in midflight ,seems have some compressor issue.airconditioning was nt work properly either.I could litarary see guests were cheking if AC is working.bt on landing it start to gv cool.which probably some one intentionaly kept .which was so bad.even breathing was bit difficult.otjer than that.for me all ok.

This leg of the trip was smoother than compared to the initial trip. Sri Lankan Airlines still have much work to do to improve the overall travel experience.

Very good crew, very efficient. Unfortunately not all items listed in duty free catalog were available.

Very professional and well managed. On time, great staff and comfortable.

Kayak company fake total I m not travel my payment reverse plzzz my credit card

Terrible experience. Unexpected wait due to staff delay was not taken proper care. Food inflight could be better where as flight attendees on flight hospitality was 100%

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

I understand and don't want food on a short trip, but tea and coffe (at least 1 cup) should be free. Nevertheless there was water available and the crew was nice.

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.

Aircraft condition poor, no inflight entertainment, broken seats, seats worn, split armrests, flat seat cushions and seat would recline. Aircraft needs refitting completely!

Need to update the staff of the airport. They tell luggage weight according to they want.

The crew on the flight was great and the food was good. The flight was on time and in fact arrived earlier than scheduled. The boarding process however was not great. I had a business class ticket but I had to stand in line for about 20 minutes at the gate before I could board. The bottleneck is that at the gate they check the boarding pass and passport all over again and there is no separate lane for business class and there were only 1 agent. The aircraft is very old . The entertainment system is antiquated and the programming is sub par.

I did not expect from Tata group like this worst experience food is too worst

Things have improved still cleanliness of aircraft and maintenance of flights, still needs attention. Crew members have become more welcoming, which is indeed a welcomed change.

Chaotic/Crowded check in. Delayed departure from LHR, resulting in a very delayed Dinner service. Since takeover by the TATAs, Air-India has become Uber commercial and not in a good way, but more like Ryanair. Most seats are now sold and at too high prices (£24 add on for a single windows seat). The promised transformation into a better (clean), efficient and professional airline is nowhere in sight ☹️ Thanks

Please improve plane conditions. Display is broken and map doesn't work

Horrible flight conditions. Entertainment system not working. Charging points not working.

They have done best within available resources and infrastructure. It is a long flight. The change from Hyd to N Delhi could have been avoided in the middle of the night to provide better sleep n rest .

No kids meal. While checking in online, no way to select meals.
