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.

Airline reviews

I was a member of Krisflyer for ten years, but my last flight to Tokyo was a disaster. I had to stand in line for four hours before check-in because they were late opening the counter, and there were more than 50 people behind me. The plane was extremely small, and the food could have been better. When I dropped off my stroller before boarding the plane, I expected to receive it upon exiting for my transfer. However, they returned the stroller to the checked baggage because they said I was late getting off the plane. Of course, I was late; they assigned me a seat at the back of the aircraft, and I was traveling with a baby! The worst part was when I arrived in Jakarta. They damaged my stroller and refused to approve my claim, so I had to pay for stroller rental because of the damage they caused. I don’t know what happened to Singapore Airlines, but I felt like I was flying with a budget airline.

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.

They made 22 hours aboard aircraft very enjoyable. I was very impressed with the attention to detail and level of service. Singapore airline will be my preferred choice going forward.

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.

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.

Excellent- a lot of food Disappointed with the premium economy pouch- did not have toothbrush and tooth paste or socks. Other airlines provide them
