The food and service was great. You have to pay a lot for in flight Internet though which is lame.

The food and service was great. You have to pay a lot for in flight Internet though which is lame.

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

The flight was delayed for 30 mins. The overall experience was good.

Overall, it was ok. However, the food was very sub-par.

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

bad… no veg food was provided eventhough i pre ordered special meal

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

The crews were smiling all the time with soft tunes when they spoke; the food was excellent. Thank you!

2 hours delay, time changes started already 2 days before the flight

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

I bought the front row seat and made and early online check in but they changed my seat to the back row without prior notice. The inflight meal was too poor, only a piece of small finger food. The boarding is a disaster, everyone is stuffed in a bus in chaos. Doesnt worth the money at all.

Poor. Flight was delay without prior notice. Poor boarding. Poor meal service. Plane was dirty and smelly. Does not worth the money.

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.

Overall very nice airline. The seats were cloth unlike leather seats I am accustom to on planes. The food was adequate.

I am a bit upset with the check in counter, I signed up a wheelchair for my mom so they wouldn’t grant us her boarding pass. We got to the airport a couple of hours earlier and they had us wait and no one ever gave us her boarding pass or the wheelchair, I had to go back and complain when it was already time for our flight to board. Since we got their earlier, I could have easily pushed my mom myself and we could have relaxed and went to the lounge while waiting… when I finally got someone to help us he couldn’t explain how and why they dismissed us in the first place.

Was on holiday with my partner and we booked with Vietnam airlines as it not meant to be a budget airline. They separated us and made us sit at either end of the plane. Not the way I planned to spend my time on my holiday separate from my loved one. How can they separate people on the same booking. They know we are together and spending quality time together.

I had sometimes my trips with Vietnam Airlines and I like it 😊

The check-in process was great, and I cannot remember the name of the supervisor, but he was good and told us about the transit process very correctly and efficiently and kindly. We were given down access and the overall process was very efficient.

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

VietJet is a discount airline like EasyJet, Flair or Spirit. I flew 3 flights in 2 weeks and all were Airbus 321's. 2 of the flights left and arrived on time and 1 left and arrived about 45minutes late. Seat pitch in economy is 29" but exit row seats have super-generous leg room. There are no power ports or entertainment of any kind. Food is best purchased on-line before the flight but there is a limited selection available in flight - cash only. The aircraft are clean and the airline is run as well as any other airline that specializes in economy passengers.

Our flight was 3 hours delayed and the airport was hectic as our boarding pass said one gate while the digital screens said another gate. Attendants were clueless and said to watch both! Vietjwt cared more about selling their merch than even providing any water for the 2 hour flight

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.

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

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.

If there could be simple free food or snack or some entertainment.

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

Horrible! As an Asian, they look down on their own skin color. Disgusting people and airlines. If you are white, they will worship you

1-Airlines did not send any info to inform the clients about changing fight number. 2-Delayed too long on runay without any explanation

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.

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.
