Top tips for finding cheap flights to Southeast Asia

  • If you are flying from London to Southeast Asia, you will fly from one of the four main London Airports Heathrow (LGW), London City (LCY), and London Stansted (STN) or Gatwick (GTW). As the flight is a long-haul flight you should arrive at the airport 3 hours in advance and you can choose to make use of one of the many Business and VIP Lounges available to you. This is a good idea for some relaxation time and a good meal to prepare you for your onward journey.
  • If your journey from London stops at Singapore Airport Changi (SIN), you can make use of the BeRelax Spa to recover from your long flight. The spa is found at the airport and offers essential wellness and relaxation services like massages, facials and much more. This is the perfect after-flight treat to prepare you for your onward journey.
  • Depending on what destination in Southeast Asia you are flying to, there are multiple routes, stopovers and options, and if you are flying to one of the more remote islands you will probably need to have a connecting flight to the venue. The most popular airlines connecting visitors to Southeast Asia are Singapore Airlines, Etihad, Austrian Airlines, Malaysia Airlines and more. It all depends on your route and destination so click through KAYAK to find your best route.
  • If you are flying into Bangkok (BKK) and want to get a good night's rest after your long-haul flight there is a hotel at the airport grounds. The Novotel Bangkok Airport Hotel is connected to the airport terminal by a walkway and is easily accessible. You can also choose to use the hotel for a business meeting.
  • If you are flying from London into Kuala Lumpur International Airport (KUL), this is one of Southeast Asia’s busiest aviation hubs.

An overnight Doha to KL. Great sleep, good service and tasty food in business class

The cabin was quite noisy as there were lots of children travelling for the school holidays. Found the selection of movies limited.

Delayed, not enough information. Had to ask for refreshments, crew could have been more proactive

The best so far coz this time it was all male steward on the economy cluster. They were polite, efficient & genuinely courteous. They do not judge you when you ask for more food & peanuts.

My first course flight (Aor-Kul) was cancelled in the morning, and they asked me to board the night flight hence I need to transit overnight for the 2nd flight (Kul-Myy) that supposed to be on the same day. The overnight stay was not provided, (I'm traveling with my spouse, a daughter (5 y.o.) and an infant (2 months old). Hence I booked Sama Sama Hotel at my own expense (fortunately using my enrich miles points). Other than this issue, all services is good.

My experience with the flight was okay. My experience checking in was absolutely terrible. I was told I needed to change my e-ticket number to check in because I missed my flight in PDX. Even when shown the itinerary, they didn't budge and sent me to KLM across the airport. KLM wasn't open until 8pm and my flight was at 7:30pm. Nobody made accommodations in any way to get me to KUL. To add insult to injury, they rescheduled my flight to the very next day, creating a very long layover and did not offer any hotel stay. After this, even worse, I found out later they delayed the first 7:30pm flight to 9:10pm. Meaning, I could have still boarded but they refused to even try to get me on the plane. As a result, I missed a day of work and lost pay for the day. Also, when I went to get my luggage, it wasn't there. It was STILL in Singapore. They had from 5:30pm to 5am to get my luggage onto the plane and they still couldn't get that right. This is the worst experience I've had flying anywhere in the past decade I've been travelling.

Orange juice change to mineral water . Should keep the orange juice.

Entertainment system was too old, crew were unorganised during boarding

No recognition for one World Emerald member. Business class seat has flat bed

No recognition for one World Emerald member. I got row 1 in business class and it was pathetic. No leg space, cramped space, less recline

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

Food quality should be upgrade. Plastic spoons looks like not good as well as food quality not up to the mark.

Everything was great specially the seats was comfortable even I was in the economy and the food was really Great👍

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

The crew was attentive and kind. The business class cabin wasn’t very full during the flight so the service was catered to your specific needs.

For the price we paid, we had a really good flight. The seats and bed (business class) was extremely comfortable. I have no complaints. The crew were very attentive and helpful. They spoke English and there were no misunderstanding although their English wasn’t perfect or fluent. You will never go hungry as there was ample food and drinks but their food for mediocre. The entertainment was limited to older movies and the wifi didn’t allow you to access some Social media. Apart from the above, it was a very pleasant flight. Would highly recommend them.

Good airline for the price. The Air stewardess are great, nothing is to much trouble. Will use again.

Great staff and food. Seats pretty uncomfortable but plenty of legroom. Entertainment system outdated.

The flight was cancelled without any reason. But the next flight to Shanghai has to be cancelled to pay penalty.

The landings were smooth . Being unable to check-in online was terribly stressful and the queue at Haneda exemely long. We paid extra for window seats and did not get them.

Flight was fine, however we were not able to check in online, this adds to travel stress. Luckily check-in at Heathrow was quick, but we did not get the seats we paid extra for. We paid for a window and 2 aisle seats from Shanghai to Tokyo leg, but they changed us to middle seats. Not good :(

It was my birthday while I was on the flight on China eastern airlines. They celebrated my day by giving me a personalized birthday card and also a very delicious pastry. I was surprised and thankful by the China Eastern crew! The whole staff was kind and professional? My second flight into China and the most memorable! Thank you-

Pros: "The flight was smooth. Food was on time . Wine is available for the anxious flyers who can’t sleep."
Cons: "Better softer hand soap , sprays and lotion . Sleep mask"
Cons: "delay of about 1 hour, we almost missed our international flight from beigin"
Pros: "Great crew in business class!"
Cons: "Wifi was terrible, entertainment is below average and angle seats for a 12 hour flight is sub par. The food was so so"

The flight was delayed for almost 5 hours, but I understand that it was not up to the company, however how they could handle the situation better, they never apologized for that delay, moreover despite passengers being there for 7 hours only thing they did was to give a bowl of instant noodles, afterwards on the plane tiny snacks, people were there starting from lunch time and we’ve arrived to destination at almost midnight

Flight was delayed for 2 hours for no reason, then we spent almost an hour after boarding because of the weather conditions. If we left on time we could avoid that 😾

Pros: "Friendly crew and helpful staff"
Cons: "Missed connection from PEK to XIY due to delayed arrival and early departure. From XIY to PEK, booked and confirmed 11 departure, changed to 12:30 without notification or explaination. Rushed connections at PEK, pretty much ran from the minute left plan to another terminal, through custom, through all the health check points, security check. Just keep the fights on time and keep the original schedules, not arbitrarily change them."
Pros: "Because of our delay, we flew with Air Thai instead of Air China....much better airline"
Pros: "The food was good. It was nice that they supply wet hot towels before each meal. The seat was comfortable with the price I paid for. The rest room is nice and clean and quite spacious. The L’occitane toiletery bag was nice."
Cons: "It would be nice to supply mouthwash in the rest room. It would be nice to have a foot step at the bottom to open the trash container. The comforter is not washed and smells."
Cons: "Seats are narrow, leg room limited, and food is minimal."
Cons: "Seats are narrow, leg room poor, and food service is minimal."
Pros: "The seats on business were comfy, the service excellent, the movie selection was fair to poor, the food was also fair to good largely because they served a heavy lunch rather than a light breakfast."
Cons: "The food and movie selection."
Cons: "More TV show choices and more Hollywood movies although I understand it's a Chinese airline not American."
Pros: "Crew was great and was happy to get gluten free food i could eat"
Cons: "Not lose my bags :("
