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. After a long-haul flight you might need to relax and have a smoke, so you can luckily find designated smoking lounges at the Satellite Building located at the Mezzanine level 2, South Zone next to the China Air’s Lounge and North Zone next to Singapore Airlines Lounge.

My experience with Scoot is very good. Will have no issue flying with Scoot again.

Good flight. Fiod was ready a bit late hence a hurry to finish before landing. Excellent crew and service

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

Every thing was fine. Some ild classical Hindi movies should be add

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

I did not like anything. Flight experience was bad overall.

The overall operation needs to be improved. The in-flight services took forever and sometimes ran out of options.

We bought the business class tickets. The check-in staff and onboard crew were excellent, providing commendable service throughout. However, it was disappointing to find that China Southern Airlines does not have a lounge at SFO. Instead, passengers were provided with a $35 per person food voucher, which fell short of expectations. Furthermore, the quality of the onboard food left much to be desired, marking a significant decline compared to our previous flight experience in 2019, prior to the pandemic.

Wuhan - Dubai. Old plane: 1. Only USB charger. No power outlet to plug in.. 2. Super narrow seat layout 3. Toilet cover consistently fell down and hit my back when sitting on it.. :( 4. Entertainment system touch screen not sensitive, and need to press hard or use finger tips to hit. Crew were very nice and accommodating though.

1. I got very poor check in experience with the counter lady . This is the first airline I ever experienced that no combine check in weight allow . Even we have 4 of us but weight counter by piece . So we wasted lot of time argue and repack . This is super crazy 2. Next I left my Samsung tablet on the plane . And I started to escalate and finally spoke to southern airline lost and found in Malaysia and the amazing answer she give is : system nothing found and please try to call southern airline in china 🧐 . I have been flying many other airlines but this is my first encounterment with such irresponsible airline response and no empathy given to customer . My feeling is nobody bother whether how customer like me feel and I’m just too small for the management to take note .

No red vine, no whiskey, no vodka. No that I wanted all of them at once but still...

No good but was short flight. Both of our China Southern flights were on time. No surprises.

The flight was okay it was the kayak customer service that was poor, I have been trying to change my name on my flight ticket 3 days before my flight and nothing got done about it even tho I messaged so many times and phoned, all I got in return was that is was being processed and still to this day nothing has been done about it, I think it’s disgusting and un needed stress to the trip.

The food was perfect. The boarding process is a bit long. Given the late boarding time, I felt very tired by the time I was seated.

Quality flight from start to finish. Customer service is evidently very important to this company. The staff really exceeded expectations.

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .

Pros: "Yes, seats were very comfortable and crew members were extremely helpful"
Cons: "Everything was excellent."

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

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 😊 🙏 😀 😉 👍

It was pretty good overall. I just wish the crew didn't have to interrupt you every five seconds to ask you if you wanted anything, I mean that's what the help button is for. When someone is tired and sleepy and still getting their bearings, turning on DND button is maybe not the first thing on their mind.

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

Ultimate customer care humble and excellent service oriented crew , perfect timing maintained by the crew . My profound appreciation.

Okay not so good or great. The flight operated by Indigo is worst from boarding to luggage handling and food. Damaged one luggage and delayed another luggage. Still did not get it, since 2 days.

I would advice everybody not to fly by Indigo, no entertainment in flight, rude behavior of staff, worst experience of my life

The flight from Doha to Mumbai with Indigo was worst in my whole life, I had booked tickets with Qatar, but still we had to fly by Indigo , worst flight

They ran out of some of the popular food items. 😞

Was unable to check in via app or website with supplied booking code (something to do with flight being operated by a partner airline, although the code didn’t work on the partner’s website either) Specified a vegetarian meal during booking, but that somehow wasn’t captured in airline’s system By the time flight crew got to my row, now vegetarian food was available. Had nothing to eat on flight from Philadelphia to Doha! Flight attendant was completely unconcerned and actively apathetic to the situation

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 :("

My luggage never arrived to Zurich. They can't confirm when it will arrive

Late again. 3 out of 4 late. One cancelled flight and one lost bag.

Charged an extra 65 pounds for overweight suitcase, Not told how much overweight but had no choice but to pay the price. Compare to Delta Airlines where I flew internationally a few days before with this suitcase and no extra charge by Delta. Comfort was horrible. I am just under 6 feet tall, and good that the flight was only 1 1/2 hours, because my knees were in the seat back in front of me the whole flight. I felt that my knees were part way up to my chest. No reason to have the seats that close. I will say to the positive was the flight crew, very friendly and efficient.

The flight was delayed as they were waiting on catering. Catering. Was eventually delivered but they still had no food. No meals for us in business class - just a bag of nuts.

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

Air hostess delayed providing food and then pulled away the tray before i finished eating

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The flight was on time and the crew very professional. Everything went as expected and I will use BA again for this trip.

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Very bad plain although I paid A business class ticket I was stuck in a stiff fixed seat without any entertainment or Wi Fi for 5 hours I will never ever book a flight on British airline.
