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.

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

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

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.
