Flights from Hong Kong to Southeast Asia: the best tips from KAYAK users

Insights shared by verified travellers who flew the route from Hong Kong to Southeast Asia 
JackFlew with Air Canada-Aug 2026
Allow plenty of time to transfer between flights. Lengthy queues for security to move between arrivals and departures. They don't like nail clippers for some reason. And long distances to walk between gates. ... Plenty of food and shopping. ... If you have access, the Cathay Pacific lounges are worth a visit.
JasperFlew with Cathay Pacific-Mar 2026
Be prepared to wait or adjust time for delayed baggage.
Verified travelerFlew with Cathay Pacific-Feb 2026
HKG airport is quite big. Be aware of the amount of time to walk to your boarding gate.
Verified travelerFlew with Singapore Airlines-Apr 2025
Go to the airports early if they have time cause both Hong Kong and Singapore Int’l Airports have wonderful/spacious shopping arcades where you can roam/window-shop/shop around, and enjoy a vast variety of Asian and western cuisines!
PaulFlew with Cathay Pacific-Nov 2024
CX Flight number but the carrier is LCC Hong Kong Express which means no meal and no drinks at all without paying. Not even water. So keep your credit card handy so you can buy a drink if you get thirsty. Seating is LCC cramped and basic. No IFE. Gate was the furthest possible gate in the satellite terminal at HKIA so allow time to walk there.
JeffFlew with Cathay Pacific-Jun 2024
signage could be better in locating transfer departure gate when you are coming off of a transiting flight. Airport has lots of amenities
EvelynFlew with Philippine Airlines-Apr 2024
Always arrived 2 hrs or an hr early before your flight at the airport just incase of some issues.

The quality and the quantity of food was terrible. I was starving to death at the end of the flight. Used serve 3 meals long time ago, now reduced to 2 meals during the 17 hours flight. Never offered wine or tea to us. We have to ask . Extremely hard to get the attention of the flight attendants. They intentionally ignore us to minimize the service. Bathrooms were dirty

The quality and the quantity of food was terrible. I was starving to death at the end of the flight. Used serve 3 meals long time ago, now reduced to 2 meals during the 17 hours flight. Never offered wine or tea to us. We have to ask . Extremely hard to get the attention of the flight attendants. They intentionally ignore us to minimize the service. Bathrooms were dirty

Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

Overall were very good and I was satisfied w/ all the food and services.

Best service airline. The cabin crew is attentive and friendly. Inflight entertainment system is good

Both the staff at check-in counter and on board were pleasant and helpful. My chicken and mashed potato was good, sauce was tasty, but the zucchini, carrot n other accompanying vegetables were over-cooked a little. (I understand the meal has to be prepared earlier). Yet I would fly on Singapore Airlines again and recommend it to family and friends.

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.

Crews are not allowed to perform any service whenever the captain deems there’s a chance of turbulence. Even if it is perfectly smooth air.

I did not like anything. Flight experience was bad overall.

Sleep pods in SilverKris lounge are disappointing, showers are great though. Food decent, not amazing. Need more toilets in lounge ideally. Flight was good but service can be better.

Seamless fussy free flight. Great service as expected of SIA.

Boarding was too soon because we arrived 10’ after boarding began and they were already giving ‘final call’. We just made it. We were at gate 35 minutes before the flight. Also, the departure communication board did not list the flight at all so we didn’t know boarding had already started.

This was our fourth domestic flight with Vietnam Airlines, and once again we found the experience very suitable. Check-in was easy and efficient. They did take our carry-on luggage, but that was fine. I’m actually happy not to deal with it on such a short flight. The flight was just over an hour, departed on time, and we climbed above the clouds into a beautiful sunset. Even on such a short flight, they served water, which we appreciated. Luggage came out into carousel in Nha Trang in good time and off we went to meet our GRAB. Also, Vietnam Airlines have easy to locate ground level offices in cities and towns where you can get assistance with staff. I liked this service as we did go visit one in Nha Trang. We would definitely recommend Vietnam Airlines and wouldn’t hesitate to fly with them again.

Really good 👍 This was our first time flying with Vietnam Airlines. It was a short domestic flight, so no meal service, but boarding was organized and the flight departed and arrived on schedule. The flight attendants were professional and neatly presented. All in all, a very good first experience. We would recommend Vietnam Airlines.

The flight boarded and departed pretty much on time as it’s just a one hour flight there is no food or entertainment so I marked that at the neutral but they do offer water and I’m sure if you needed some food you could bring your own onboard. This was our third internal flight with Vietnam Airways and I recommend them.

The flight crew and attendants are very professional and polite.

Food and welcome services were good , however we experienced issues with the entertainment system and poor headsets

Average, not more then that. Cannot compete with Singapore Airlines

Overall very nice airline. The seats were cloth unlike leather seats I am accustom to on planes. The food was adequate. I had to use a paper boarding pass as they do not like electronic boarding passes. I scanned my electronic pass, but the gate agent requested the paper pass. Luckily I had a paper pass, although my electronic pass worked and when the paper pass was scanned it stated I was already on board.

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

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

In between two meals period they're not providing something like banana / cup noodles or bugger. It's really fell sad that I was asking have to wait for 3 hours for second meal. (breakfast)

The crew are timely, friendly and professional. I was very impressed.

They overbooked the flight and reassigned my seat. To add insult they lied that my assigned seat was broken and promptly gave it to someone else

Jain veg meal I opted was super in taste but there was no sweet/desserts with it. I was a big missing in the meal...Please add some sweets to end the meal with 😊

The meat-and-rice combination was a good idea, but the food could use some improvement. The meat looked a bit mushy and almost like ground meat, which wasn’t very appetizing, and the flavor was just average. Other than that, everything else was great.

Weather delayed arriving flight and even though I made the connection, my luggage did not.

Great! Internet is below its competition. Poor connectivity quality and speed.

It is too long a flight to not have free access to internet. Should not charge. Should be some hours free.

My boarding experience was so bad. While traveling from LA to HYD, the boarding was smooth. But the boarding experience from Hyderabad to LA was utterly poor and unprofessional and caused lot of anxiety and stress. Even though we were at the airport Boarding well in advance to accommodate for Immigration and Security Check, Cathay Pacific Boarding On Ground Crew has done a very unprofessional job. It is one thing to follow rules, but being inconsistent and not being able to communicate this clearly is wrong. I was not aware that my laptops weight in my backpacks is also counted against the cabin baggage. While coming from LA to HYD, the ground boarding crew didnt ask for this. They just checked the Cabin bags weight. But at HYD, not for everyone, but for some people they enforced this. Our Checkin Luggage was carefully weighed at home and was accurately measured to 23 kg, Now they asked to move all the weight in our Backpacks where most of the weight is from Laptops and tablets for each family member, I need to accommodate this ~10kg from 6 laptops in to one of the suit cases and pay extra for excess baggage at the airport boarding place. Without a weighing scale how can I accurately move all the items from cabin baggage to one of the suitcase. D Venkatesh is the guy who enforced this. But I dont have a problem with the rule enforcement, but the way he guided us in solving the problem. I was willing to pay the extra money for the extra weight. He told me that the 32 kg excess baggage is allowed with 150 USD. I understood that 32 kg is extra on top of the 23 kg chickin baggage. SO I pushed all of them to one suit case and then when I took this suitcase, I was sent back saying that he meant the total as 32kg but not the excess should be 32 kg, I had to go out of the line make these changes without a scale thrice like this. They literally harassed me. Noushad his manager was sneering at us. When I said, I am going to complain about this, my wife heard him saying some bad words in Hindi. You get one chance to harass your customer. I will never board Cathay Pacific again.

I’ve flown 2 better Asian airlines in the past year.

Captain smooth landing, Crew efficient and helpful. We saw Mt Fuji from the plane. Thanks.

On time and smooth flight from San Juan direct to Sint Maarten.

Just to be expected on a budget airline. Since all the flights were either late on the evening it would help to offer some food for purchase Since you tourists cannot buy decent food withoit local vaccination record in hong Kong this would really to help Using phone to submit electronic data is great but for the elderly this is a hassle

Flight cancelled without notidication, had to book an emergency replacement flight at the counter

Our luggage broke and what we get back was only 26$ plus the transit in hongkong was terrible and the airline itself the screen wasn’t working but there was a proper seat space and the crew was nice and professional

speedy loading helpful staff. and clean. food is not that great

Departure date of the ticket was ONE WEEK LATER than I purchased it for. Total failure on trying to get it reissued for the date I was to fly on. Will NOT use Kayak next time due to this screw up on Kayak's part..

On-time takeoff and arrival Cabin crew very helpful, especially the crew manager (I think) (young gentleman with glass)

I cannot check in online , and not able to select my seat

Watch for "bait and switch" - cheap prices, but not obvious at all at point of purchase that there will be an undisclosed charge for baggage - and less obvious that you will have to purchase baggage at an eye-watering level. Better still, if you go this airline, leave your gear behind and buy a complete wardrobe when you arrive in country and still be ahead. The staff were very pleasant, both at counter staff level - they were clearly unnerved by having to charge - and on board.

No entertainment service which equates them with budget airlines. But their fare are regular airline fares. Aircraft are old and seats are worn.

The crews at check in counter are not professional, they are talking and playing around. Also no entertainment on the plane

2 failed landing attemps before going to Nagoya airport for refueling. After 3 hours of taxiing, we still needed 3 attemps before a succeeded landing (after the 5th attempt finally!). In total, 11 hours inside the plane instead of 4h30, and with only a crappy piece of bread to feed us. A shame.
