Flights to Southeast Asia: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew to Southeast Asia 
AndreaFlew with Qantas Airways-July 2026
Taking the train is easy. If not allow at least 2 hours if it’s a morning flight. Also if you have to pay extra baggage. Ensure it’s paid before you go through immigration. Enjoy!
ScoutFlew with Jetstar-Mar 2026
There will be no internet or phone reception from the moment you start boarding. Send your goodbye messages before boarding. Wish they offered at least free wifi for messaging apps like WhatsApp. This seems to be common in Europe and great to include.
Goh Hua ShengFlew with Turkish Airlines-Feb 2026
early check in at the counter is available just that the downside would be arriving at an odd timing if stopping in singapore.
Verified travelerFlew with Qantas Airways-Jan 2026
leave time to get to next gate. some are a long walk.
StephenFlew with Jetstar-Jan 2026
Pack light bring snacks and entertainment. It’s just a seat.
RonaldFlew with Philippine Airlines-June 2024
- eat before flying. - bring your own entertainment like movies, tv
FrankFlew with Scoot-May 2024
Download movies etc in advance so you don’t reply on WiFi onboard

Airline reviews

I had the worst experience of my life in travel. Due to circumstances beyond my control (catastrophic traffic accidents on the highway between Gold Coast and Brisbane) I missed my flight for the first time ever. Because I booked through Kayak Singapore Airlines were not interested in helping me. They told me to contact the agent that I booked through. I was extremely stressed as I had connecting flights in Europe. First Kayak told me that the next available flights were in four days time. Then they told me that they could do it but at a cost of $2600 AUD. When I agreed he told me that he was having trouble getting it through Singapore’s system and he would contact me further once it had been done. When I had not heard from him after several hours, I phoned Kayak again, spoke to a different person who said he could do it for $8200. I declined and told him to cancel the booking. The worst part of this experience was that I had booked 5 flights altogether with Singapore including Premium Economy on two legs and Singapore cancelled all my flights including the return legs leaving me with having to completely reschedule my entire trip. Kayak refunded me $2000 from $5200, obviously leaving me out of pocket. This has left me feeling that I will never deal with Kayak or Singapore Airlines again.

Crew were so busy Anna so awesome. I was in a seat that got my food nearly last but the crew were Just awesome.

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

Headwind delayed our flight which wasn’t the airlines fault

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Food could have been better. Too many passengers getting up and down all the time.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

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.

amazing service for a 4hr flight, great selection of movies and music, blanket options, good toilets

Crew excellent calling me by name ! Only downside was no inflight WiFi

Food was great. Hot meals. Entertainment- not so good. They only showed one tv filipino series with only 3 episodes for a 14 hour flight.

Ground and flight crew very courteous and professional. Seats are just ok. Entertainment could be upgraded with newer movies. Food was not good at all.

Great ride! arrived safe and sound. Everything was great altho its still uncomfortable seats too small space to pass through in.

first time flying PAL/WAMOS, ang got to say, i’ve had much worst… the good: - front sitting is not too bad. legroom is pretty good considering economy standards. - staff is friendly and pleasant, starting with checkin, boarding and flight. not unforgettable, but pretty good. the bad: - boarding: stick with rules. besides priority sitting, when you say board from certain range of numbers (starting from back), make sure you let everyone know to stick with this… not with everyone letting in all at once! - food: had fish ad family members had beef. both are quite bad (saying this nicely). the fish is dry, whilest beef is rough as leather. both tasteless. - washrooms arr dirty! - seats, though good legroom, not much padding, hard on the backside! - entertainment: feature movie is the bachelor (circa 1999). no music offerings.

I was thrilled with this flight and look forward to flying again with Philippine Airlines in the near future…thank you

PAL Airlines is always delayed most of the time. Please try to avoid it.

I didn’t get enough water. Couldn’t ask because there’s no attendant checking on us from time to time.

This trip was canceled by the airline and we have never been repaid or rescheduled despite many inquiries.

A good standard flight, a little delayed, on the return flight, comfortable during cruise hour. The food was tasty, the tea pleasant, standing in the rain, on Launceston tarmac, was stupidity. Just delay the exit from the airplane, don’t have us standing around, while another plane slows its propellers. That’s common sense, but overall comfortable, clean toilet, good legroom, I paid for that, last on, first off, get a front row seat.

Smooth flight with great staff shame about the hard seats

Cabin crew were really good. Flying in to Perth from Adelaide on domestic flight. The arrival for wheel chair use however has no air bridge provided. Unloading meant a scissor lift. Otherwise a good service.

Knees in back from passenger behind, limited seat pockets, no entertainment.

The Ryanair of Australia. Not impressed. Forced me to gate check my bag as it was over their weight limit. Charged me $125 for the privilege. Then said plane hold was locked and it would have to go out in the next flight, which was the following day. Explained that I was on a cruise the next day and the plane would not arrive until after the ship left, and that it would be impossible to catch up with the cruise at any point. Lady at the gate unimpressed. So to sum up they were ready to charge me $125 to lose a bag. Finally got it resolved by appealing to management, but the whole episode was not good for the blood pressure. The gate lady said they followed the Ryanair business model which means first time passengers get penalized for doing things that other airlines routinely allow.

Delayed 50 mins. Check in was excellent, boarding was good, everything else was OK and perfectly acceptable for a budget airline. Price was excellent. I noticed this airline had two other flights to our destination cancelled so not very reliable.

Horrible. The people that get this flights are very sick, dangerous and unhygienic

Jane at Sydney International airport check in was amazing. She set up the whole experience to be a positive one.

The smells on this plane were disgusting. So many sweaty and unhygienic people i couldn't stand it. I dream of being anywhere else in the world when I am on a JetStar flight they suck.

One of the better flights I’ve had w Jetstar. Smooth boarding, early take off, on time landing, very courteous crew, clean plane.

My flight from PEN-KUL was re-timed for two hours or so due to some technical issue. It was not conveyed accordingly by the staff. Info only received via fellow passenger who also mentioned about the possibility of changing flight but different airport SZB. Changing flight is not easy since everyone is fighting for available seat unsystematically. Anywhere, I and my wife managed to get seat for slightly earlier flight from the retimed one. The issue should be handled more professionally and systematically.

Freezing onboard and staff refused to give me hot water “because we were landing soon”. The plane arrived at the gate an hour late. And there’s an air leak in one of the bathrooms. Very scary noise.

Batik Air is racing to the bottom of the list with its consistent flight delays. Especially out of Malaysia. Shocking that they keep getting away with it without any form of punishment from the authorities. Also very inconsistent rules on cabin luggage.

Did not like that we were not informed about the 4 hour delay, crew not friendly, noone at terminals to consult with...all employees for Batrik were behind glass aftervgoing through security at the gate again. Why no agent at Gate H 10 to answer questions? And no apology. Updates would have eased anxiety. Boarding is disorderly also.

During this flight all the crew just focused on making money by selling food and drinks. There was only one washroom open. And it really smelled bad and wasn’t usable. Even to watch something onboard entertainment u have to rent headphones pathetic airline but only one with direct flight so pretty much the only option from Karachi to KL

Delayed for 3 hours, need to pay extra for drinking water.

The OD2204 KUL-LGK was delayed 40 minutes due to air-condition malfuntion, after inspection the technician give green light for the flight to go as usual but the air-condition is still not working properly, passengers complaining to the stewardess but they cannot do anything, I did tweet to @malindoair to complaint but no reply from them … hope this Batik Air is not having problem like Rayani Air and I do hope the management do respond to my complaint as well

2 delayed flights - hotel layover in a different country- lost baggage.

Good leg room ... air conditioning was a bit warm don't Book row 8 ... no windows

They got to the terminal late, with no one on the arriving flight, boarded us late, and left us sitting there for 2 hours before they got us off the ground. They knew they were going to be late, yet they never got an updated flight plan from their head office until long after the flight was supposed to leave. They could have cut the delay in half, of at least let us stay in the terminal. Really just horrible planning.

For budget airline, it’s not bad at all. It’s definitely value for money. I added on the priority check in and eSIM. It’s well worth it.

I was unable to check in online so had to line up at the airport. When I got to the counter? The staff told me I had to check my carry on luggage, which cost $70. When I boarded the plane, I saw many suitcases that were bigger and heavier than my carry on… so not sure how they were able to bring them on and I wasn’t …

The flight was OK, but you need to warn passengers going to Vietnam that the full first, middle and last name needs to be in the issued visa, At least 5 passengers on that pane did not have that. We all had to pay $298 each to some agent to amend the visa. At least one lady could not and was left behind.

Vietjet tried to steal extra money from passengers by forcing them to change the name on the ticket that was correctly filled in on an English form online when ticket bought online. I bought the ticket via a foreign website where the language is English, At filling in the passenger's name, it says middle name first, then first name, and last name, That the ticket done and printed. when my wife checked in the staff at the check in counter said that her name was written wrong, she must fill the name in Vietnamese style, writing the Last name first, then middle name, first name comes last, even though her name was not misspelled. At the aiport I asked the Vietjet customer service, if it is written in Vietnamese way, it will be wrong when she travel abroad ? The custom service could not answer. It took over an hour where my wife was thrown like a ball between the check-in counter, to the Vietjet customer service , then to passport control. The cost is 110,000 vnd for change place in vietnamese way, I thought if there are millions of passengers who have done the same mistake, how much money Vietjet raked in every year On the flight, it is not allowed to sit in the empty seats in front or next to me, I sat in the middle in a row where two big men were sitting, I really need to change seats but the crew asked to pay extra to buy the empty seats. It is petty and cruel of Vietjet. There is no other choice than the state-owned airline, then you have no choice but to swallow the bite

체크인을 담당하는 승무원이 아주, 몹시 불친절하고 전문성이 현저하게 떨어졌습니다. The flight attendant in charge of the check-in was very, very unfriendly and markedly less professional.

Flights on time is good. Crew should take care of passengers more.

Not punctual in departure and seats are very tight and narrow. Crew should handle noisy families during flight.

Flight was delayed 2 hours, which seems regular with this airline. Aircrew were avarage, friendly but robotic. At check in I asked for a spare seat. Got some stupid response about loading capacity (it was 85% full!) Then passengers behind jumped up and moved to vacant exit rows, they obviously didn't pay for. Waited over 20+ minutes to disembark, with ground staff trying to squash all passengers onto 1 bus. Causing even more delays. Unsafe and stupid! But this is a problem at Saigon airport. Overall a very average experience!

I wasn’t able checkin on line so wasn’t given option buy food so I had to site watch everyone eat when I was hungry. That’s F-up

No in flight entertainment, no food, not even drinking water, uncleaned flights, smelly bathrooms, and above all no baggage allowance, they charged us 53700 yen for the baggages.
