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.

Overall, very pleased with this flight. Boarding could be better because boarding was announced without a microphone so people didn’t know to line up until we heard the staff walking around to announce it. Also, had to stand in line for 10’ before we started moving. My husband who is impatient and cannot stand for too long did not like this. The rest of the flight- crew, food, and entertainment were very good.

Boarding and deviating was mediocre. At boarding they have not prioritized Business class. During debarking they prioritized premium economy. Also bus rides both times.

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

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

The biggest problem was that I originally had a seat in the first row of premium economy as I had booked months earlier. I checked in and my boarding pass showed the seat in the first row as I had specified. When I got to the gate, the agent took my boarding pass and changed my seat to one in the last row in premium economy against the window. I had specifically booked the first row early for the legroom and for my ability to easily get out and use the restroom when I needed, since I do that quite often. The gate agents explanation was that the food tray on the seat in the first row was not working, so they gave me the seat in the last row. However, when I got on the plane, somebody was sitting in my original seat, and they sat there for the whole 14-hour flight with the tray working perfectly well. I was cheated by someone at the Cathay gate in Hong Kong. It was an outright, unforgivable lie by the gate agent or someone else at Cathay Pacific. I think this is very poor and inexcusable conduct by the people at Cathay Pacific. Perhaps somebody paid the gate agent extra money (bribe)to switch my seat and make it very difficult for me, or something else, but t was a sad experience and a very negative mark on Cathay Pacific.

They need to take training from emirates or Singapore airlines, it’s premium in pricing but poor in standards

Boarding crew at the gate mostly were being difficult. But one on board much better experience with crew and service!

Good. However the passenger in the search next to mine kept coughing. When we landed in Dallas we had to pick up.bags instead of going strait to the destination (which passengers do in Atlanta)

Although I am a lifetime Gold Premier member on another airline association, I was placed in a inside passenger seat on both legs of my journey from SFO to HKG and onward to NRT. However, i was lucky enough to have befriended two other passengers (who were related) in my row (row 62) and therefore was kept entertained with conversation for a large portion of the overnight flight from SFO to HKG. Normally, on a Star Alliance carrier, I typically can have the seat of my choice (aisle seat) and also a Premier seat (wider and longer legroom). I was a bit disappointed that no recognition of my Gold Premier status was acknowledged by Cathay Pacific on either of my flights on Sept 26-27. The food was actually very tasty unlike the typical economy class menu. Also I appreciated that the dinner drinks were served first (prior) to the main meal on the HKG to NRT portion of my flights but drinks were served AFTER the meal had been distributed (less appealing for thirsty passengers). I was happily that there appeared to have ample cabin space for most everyone's bags ---although I did have to pay more than $400 in extra baggage fees as I had brought 4 bags with me Overall, I was impressed by the diligence and professionalism of the flight crew.

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.

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

At the boarding gate there were repeated announcements about the plane being full and there not being enough overhead storage and how we were only allowed one cabin bag and anything else would be charged. Piranha staff made me pay for an extra bag...when I got on the plane, there were empty seats galore, not full at all. I will avoid these people in future.

The staff were excellent, the seat comfort is very poor on a three hour flight, Scoot Airline seats were poor quality also, they are okay for a short flight time of no more than one hour!

Super delayed. Delayed to get the bus, delayed to get off the bus, delayed to take off.

Boarding had us in a tunnel with no AC for 15 minutes. Not planned well. And you have to pay for water, get at airport

Very good no problems with this airline friendly staff at checking ask you where you want to sit left on time everything easy, it’s a budget airline no food or entertainment unless you buy on the flight but who need food etc on a late night flight.

Delays on the tarmac, uncomfortable even after paying extra for premium seats. Bags lost in transit, no compensation provided

i liked that the flight crew noticed my discomfort with the small leg space (I'm 6'2") and offered the emergency row. The fight attendants were very friendly, a definite strength with Cebu Pacific. I didn't like the leg space in my original seating.

The flight was delayed for 3 hours and I missed my transit flight.

Poor service in Bangkok. Flight attendant is not friendly. You have to buy everything like water and coffee. Expecting for International should have free food or free snacks.

Waited Over 5 Hours for a 1 1/2 hour Flight. Manila AirPort is absolutely pathetic. This was after Cebu Pacific personnel tried to overcharge me for excess baggage.

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.
