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!

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.

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

It was good, on time boarding. Have a good service. .

Better food quality and suggest using the 777 for the HKG-BOS leg instead of the A330 since the seat pitch seems better on the Boeing.

The legroom in economy on an A321 is wholly inadequate for a 6’3” man. Deeply dissatisfied.

Food isn’t hot, seat is too tight even for a person weight 120 lbs.

The service was better on this flight from the long haul one, but still very poor from The Cathay Pacific of the past.

Seat is too small. Food selection is limited and often ran out of selectable item.

The go to HK trip will easily giving jetlag, but coming back to Chicago has no jetlag because of the time taking off matter.

For an international flight, the service was average at best. It could have been significantly better, particularly with regard to the food quality and options. Additionally, having only two restrooms available for the entire Economy Class made the experience less comfortable and resulted in long wait times.

The staff from beginning to end we're friendly and helpful. The food and beverages were quite good (but see the comment below). I also liked their entertainment options, as we'll as their frequent attention to the airplane restrooms. Here are the reasons this is not a 5-star review: - You have to pay for WiFi on the plane unless you have some level of seat upgrade. - CP sent me a warning that the name I entered to book didn't match my passport. True, but the form for entering my name didn't allow for anything but a middle initial. This lead to a lot of chats, phone calls and stress before finding out at the ticket counter that it didn't matter. CP has modified their notice to now tell you this key bit of info. - After consuming a chicken dinner they offered (Kathmandu to Hong Kong), I developed symptoms entirely consistent with salmonella, beginning about 6 hours later. There were some odd things about the serving of this meal, too. Our row was the last one served, and we were given a tray without the entree on it. About 10 minutes later the stewardess came by and said they only had one chicken meal left. My seat mate and I decided he would have the lamb and I would take the chicken. I think I lost. I suspect that this entree was left over from an earlier flight and they were scrambling to get the last row fed. My seat mate and I were the last two to receive our entrees. I am not accusing CP of giving me a contaminated meal - just that the onset and progress of symptoms closely match those of salmonella poisoning. I opted out of the first meal on the next flight 13 hours later, but was fine after that.

Good good, good seat, good entertainment system. Customer service is good but can be more polished if CX charges a premium price.

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

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

Kind of worried due to typhoon but yeah we can't do about nature thing. So okay naman kudos to all crews and pilots for the safe landing.

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.

Cheap flight but more expensive when the airlines demands you pay over 30$ for 1 kilogram overweight ( it is 8,2kg I have for carry on baggage) The flights announcement 2PM, and it departed 4 PM, no announcement for delaying, People says Vietjet is delayJet airlines in their blood.

Our flight was delayed for about 3hours however the ground crew made it sure that we will not miss our connecting flight from Hanoi to incheon.

Seat pitch is narrow moreover the agent assigned seat in front of emergency exit window which is not reclined. A terrible 4hr 40min flight from HAN to DPS

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.

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!

No water or snacks. Crew did not give us arrival cards. There was no need for more than 1 flight attendant as they did not do anything

As usual...the airline tries to pack as many bodies as possible on the plane. Very little leg room...although the flight was so short there was no inflight food or beverage...you could hardly put the tray table down if there was food/beverage service.

This was the worst flight (domestic or international) I have taken till date. Check-in and boarding experience at the airport were fine. I understand its a budget airline, still some basic stuff was missing. It's an international flight of almost 5 hours duration however, not even water was served to the passengers. If you need water, you have to go to the Crew Station and ask them for water. I asked him to fill up my own water bottle to which he denied and instead told me that I can have 1 Cup of water. When I informed, that we are total 4 family members needing water, he asked me to bring everyone to the Crew Station. Which I really don't understand. The cabin AC was not working or the temperature was kept at such a high temperature that I (and many others) were literally sweating. When I requested the cabin crew to reduce the temperature, my request was ignored twice. Finally I again had to go the front of the aircraft and ask the crew member to set it to 23. Then it was adjusted and we felt a little better. Overall a disappointing experience. They need to improve on lot of things while still keeping the cost low.

Flight has change gate in the last moment and announce last call . Our experience is we are booked flight from Dps to ho - Vietnam .my flight actual time was 2:05 pm but flight departure 1 pm . Service was not good
