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.

The plane had a technical problem it would delayed 10 hours but they just gave limited information and put all passengers into the Miracle lounge. Ther were not enough chairs and so on.

Ensure there is a choice of food for all customers and also enough food

An excellent airline; polite and courteous cabin crew, excellent meal and drink service. Highly recommended.

We boarded the plane at 1:20 pm It was hot. There was no air-conditioning It was stifling They kept us on the plane sitting there for 1 hour and 10 minutes

No space in between the seats as per them the average height of human is 5’3” and weight as 55, so seats are designed as per the same. Also, the aircraft was dirty and full of insects

when we arrived at Taipei no one help us to get boarding pass. we saw a few people there asked them for help but they just ignored us. There was a guy told us to call Starlux number to get help but we don’t know how to dial the number until there was a lady working there helped us to call Starlux customer then someone came down took us to another counter for boarding pass. Very confused and inconvenient. We might not choose Starlux again in the future.

There was no entertainment and food option limited But the service was first class on an economy flight

They didn't have a vegetarian food in spite of the ore order

Technical problems checking in. Had to wait a long time while they got things ready.

Vietnam airlines is just one step upper to the cheapest one (vietjet, if you wanted delays and cancel or feel like a criminal then vietjet is for you) for sure better customer cares and on time.

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 :("
