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.

The crew have great customer service but their economy seating isn’t the most comfortable for a 220lbs+ guy and the food wasn’t bad, but wasn’t exceptional, either.

The crew have great customer service but their economy seating isn’t the most comfortable for a 220lbs+ guy and the food wasn’t bad, but wasn’t exceptional, either.

Food option Hindu veg to Hindu non veg request was unheard

This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

Service excellent would chose Singapore airlines as my first choice

The staff were amazing and very kind. The seats recline a little too far back and are up close when sitting behind.

My groups frequent flyer star allianceUnited airline miles was not accepted. The Singapore premium economy bag had to be requested, it was very lacking- no toothbrush. I paid more than double than economy but could only use the bathrooms sharing with economy which was hardly available and had to wait in line. Is the 2X $ worth it just for a larger seat???? It is questionable. Seats were not that comfortable. My husband’s seat had white stains on it- had to wipe it down. Our headphones did not have covers on it. Food- way too much.

The booking experience was bad. Our six character booking ID number disappeared the day before the flight, We could not find out what happened or what was the status of our flight, scheduled for the next day. We finally found the right number to contact Singapore Airlines on the matter (not easy). The Singapore agent worked through the issue in a little over thirty minutes on the phone, the day before the flight. That was great. I'm very happy with Singapore Airlines and their performance. Contact with a competent person on the matter was near impossible. It seems no one in business these days wants to deal with customers once they've pocketed the money. There were resellers, including Kayak, involved in the chain. When we finally got through to Underpricer, we did get a return call that could have proved helpful. But by that time the matter had been resolved by the Singapore agent. Majestic Vacations, the reseller who received the payment was less than worthless. That's just a fast buck operation. Ugh.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

Could not really fault anything. We had a really short time between flights (about 45 mins), and had to get across the other side of the terminal. But we made it and crew were helpful. Food was good and service for the kids was great.

On time, friendly staff and decent food. Would definitely recommend.

Nothing special.. they could have provided something to eat without a charge

Terrible plane small airbus good for a 1 hr trip I booked business as it is. A night flight and 4hrs trip it was an ordinary economy seat with no one next to me what a joke what a stupid decision to buy business

Crammed like sardines into the middle of the middle 4 seat row for an 11 hour flight was a terrible experience. No attempt made to help passengers sleep by dimming lights or shutting window shades. Small mediocre meals. Not enough good movies/TV options. Hopefully we will never have to do this again.

Edelweiss is now Nickle&dimming, not even a complimentary wine on the intercontinental flight. Sitting space is the smallest I have ever seen.

overall the flight was good and we were happy they waited for us. However, our luggage didn t make it and this caused us a lot of problems.

Ghe issue was with the delay caused by the late boarding. We had to run to catch our next flight, barely made it and then our luggage didn t arrive with us. Really bad organizing.

This was an upgrade to business class and really enjoyed the experience. Much better than my earlier flight and thank you.

The seats had no space at all beyond the knees. The seat in-front literally reclined on your face, very uncomfortable plane. Was nothing like the normal SWISS experience. The food was okay but could be better.

I never share this kind of things but I have to share this out of respect to myself and how surprised I was I got a shoulder injury so I went to Turkey to get a procedure to my shoulder ( I can prove and provide it with documentation from the hospital to you) and on my way in this flight, I asked one of the crew members who’ s name is j. Muller to help me to lift my carry on to put it up in to cabinet and she told me she can’t do it , and I said I m sorry I m injured , I really need help , then can you please find someone who can help me ? And she gave me this nasty attitude and refused to help me . Then I was shocked because all I asked was for help, i didn’t even ask her to put my carry on bag up for me , all I asked her to help me so we can do it together. Then 5 minutes later another crew member who’s name is Jenny Rutz came and asked me if everything is ok And i explained her what happened and she told me if I create more problem, she will not let me fly i was shocked, all I told her was I was injured and I needed some help to put my luggage up . I am extremely shocked and upset , this was so unprofessional, rude and unnecessary. I thought their job is to help us in our flight. She disrespected me , embarrassed me, made me feel like I m a problem and threatened me to get me out of the plane In front of everyone I am 41 years old mature and kind woman, i have never in my life experienced something this unprofessional and this disrespectful ever They both turned something so simple and normal into this terrible experience for me and for the people sitting around me . So it was so uncomfortable and unfair that the other passengers who were sitting around me and next to me got negatively affected by the event and told me to take their phone number so that they can be my witness for the crew member’ rudeness and unprofessionalism I m still very upset how can people be this rude and heartless I will never ever want to fly with your airline company again

Crew was wonderful, snacks were so good and quite a variety for free, food was mediocre, big selection of movies and they kept lavatories pretty clean throughout the flight

Turkish airlines always is an excellent airline, bottle water, comfort kits were provided. Decent food on board, friendly staffs.

The first flight got delayed 1 hour and that made me miss my connection flight which made me arrive 6 hours later.

Customer service is very bad. They don’t understand English or Arabic which made it very hard to communicate with them. Also when calling to discuss any issue with ticket reservation they hang the phone on you even when speaking to the manager. I will not fly Turkish airlines and I will not recommend to family and friends

It is much better than other airlines but not the best for the price

Awful seats, poor air circulation. Smelled like poop for 3-5 mins after someone used the bathroom. Child screaming for 13 hours

Entertainment monitors did not work in the seats & it was so hot in the cabin. One of the most uncomfortable flights I've ever taken.

Turkish Airline is great! The fact that they provided a hot sandwich for an hour flight is truly amazing. I can't say enough good words but Thank You!

boarding from the lagos airport is always very chaotic. The seats on the place are not comfortable (old planes are always used on this route) and the screen chargers for my phone are both not working (both seats).

Flight crew was very nice and we had a direct flight, which was great. My seat was very cramped, despite paying for the seats. The food was terrible and the check in process was a bit chaotic.

Inflight wi-fi is below par and difficult to access.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

There is more space in this economy seat. It felt like a better layout, not so cramped.

Wonderful I upgraded from premium economy to business and it was totally worth it. The crew was fantastic. Very attentive positive. They made me feel right at home. We were on a 747 business class second story seat and it was fantastic.

Be on time. Constant delays, missed connections. No excuses. Weather was not an issue

The connection to LYON was very tight. The flight was nearly finished boarding when we got to the gate

Well the flight was 3 hours delayed taking off which lead to missing the next flight in Newark and an overnight stay in a hotel (at my expense) for a next day flight, 1.5 hour long immigration line, etc. Let's just say my travel experience wasn't pleasant.

I did not like that they failed to put my luggage on my connecting flight to Athens. I was promised it would be located and delivered within 2 days but later told there was no information on its location. This caused me to have unplanned for expenses because I then had to purchase new clothing to wear on my vacation. I did not receive my luggage until my return flight home. I will not be traveling with them again.

Absolutely the most awful experience in the history of service from gate agents to baggage handlers. Never will i use kayak or Lufthansa again. Ever.

No internet, very narrow seats insufficient room for three passengers with encroachment.

Very smooth flight and crew was very attentive and helpful

No entertainment and the seats are well worn.! To the point it feels like your sitting in a bowl

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Everything was fine except not posting the gate number until 14 minutes before boarding. In an airport the size of Heathrow, that was unacceptable.

We already had a five hour layover in London, and then they cancelled our flight about half hour before we were due to board. They wouldn't give us access to the lounge and hanging around the extremely busy terminal for another three hours until our next flight was crappy. 8 hours in a busy terminal is awful. The least they could have done was give us access to one of their quiet, comfortable lounges for the inconvenience. I heard from others that they do this a lot -- cancel these short flights if they're not completely full. When we got onto the next flight it was absolutely packed and uncomfortable. Just very disappointing. British Airways used to be a great airline to fly with, but it doesn't feel that way at all now.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

They took good care of me on the plane and had it not been for handicap assistance I would definitely had missed my connecting flight . Not BA fault but The airport security instead . Two hours is way too long for security

The least comfortable business class seat I have encountered for a while - very very firm when reclined making sleeping difficult. Cost cutting is visible everywhere - no offer to refill drinks (the wines were not good - so no real issue there :) ) Just not worth what BA charge

old seat need to go! outdated and uncomfortable. I waited 40 minutes for my bag

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.
