Although booked meal of fruit only The crew had not received this special meal The same happened on my flight Bangkok / CAN The films are so old that best is to use own computer to watch downloads . Serve nuts but they do not warm up . Service is attentive , WC clean

Terrible. It’s like they are stuck in the dark ages. I brought a standard carry on suitcase and a back pack - I was told I could only carry on 7kg per bag - in business class, I was forced to remove articles from the suitcase and put them into my backpack! That’s the most ridiculous thing I’ve ever encountered in all my years of flying. The two bags weighed the same amount but one could not be more than 7kg. Holy cow.

They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

I give EVA 5 stars in every category. I enjoy this airline and it's great team of employees. I always highly recommend EVA to friends and family and everyone.

The flight was delayed going out of the gate at BKK that made it a difficult challenge to get through immigration transfer at tapei and make it to my departure on time. This appears to be a recurring issue. The flight crew and cabin crew were excellent. The food was very nice.

The boarding efficiency was good. A couple of the flight attendants did not seem in the best of moods. Overall it was a good experience.

The setting configuration of the aircraft stinks. Nobody should pay business class fares and be so uncomfortable. The design of facing fellow passengers is a brilliant nincompoop.

Entertainment is limited with a relatively old catalogue. Wi-Fi never works and the cabin and lavatory had evidence of a lot of scuff marks and temporary repairs. Nothing unsafe, but a bit tatty in places.

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

USB charging port was not working at my seat 48K.

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.

Air Asia just dreadfull. Always poorest customer service and very unwelcoming staff which is clearly bread in from the Top down from the CEO

Everything was good. The red seats were a scam. Just like any other seat but red. Although they let you board earlier which was very nice.

Other than the bus wait time to off board passenger when we reached Don Muang, everything else was excellent

Very good, it would be good if payment for drinks could be accepted by card too.

Ontime, no frills, the cabin is clean, the ticket price is lower than the full-service airlines.

Paid for a meal we didn't receive. They admitted they had forgetten ours. No compensation or rectification offered. We requested if they would just give us a glass of wine instead and we would call it even. Crew advised they could not do this and to go to Air Asia counter on arrival and request a refund. Our flight didn't arrive until 2am so this was not a viable option. The crews solution was if we wanted a wine we should purchase one. I was unhappy with that suggestion considering they had already ripped us off with our meal.

Took 4 flights in 5 days 3 out of 4 left late about one hour each.

The boarding process was very poor - refueling on so rear ladder blocked. I think while boarding both ladders should be accessible so that passengers are comfortable instead of crowding through front ladder

No WiFi or movies. And the seat We’re uncomfortable. Good thing it was a short flight

It was on time! First time in a long time for Air Asia. Thank you!

Never on time when I fly and Thai Vietjet App is too complicated. I had booked und paid for seat number 15A but when checked in, I got another seat number and row. I paid extra 50 bath for what??? They couldn’t change and I got no refund. No time to discuss with the ground crew to change it. I would never pay for seat anymore.

Excellent experience nothing could be improved with staff. Was hoping someday the airline will use tape recorded lfor languages that are not common to staff. Probably with AI it might be a good addition

Need more where chair assistant helper I request, but no one help me.

We were packed in like sardines. They did not even serve water on the flight!

Everything was good just the part on the need to transfer via bus to plane

Around Asia, Vietjet is always my favorite airline. Great service and beautiful stewardesses :)

I get tired of Viet Jet's regular delays. I tell myself every time that I need tp switch to Air Asia, which I have, but AA doesn't always have flights when I need them. Oh well...

Worst experience, hands down. With a movable departure time it's impossible to know at what time to go to the airport. On the day of my return flight I received a kayak email informing me that my flight was bent rescheduled for an hour earlier. I literally had to run to the airport to learn it wasn't true. Never again

There were four delays over a period of 3 1/2 hours with very little advance warning. There was no explanation offered as to the reason for the delays. I hope I never have to fly a Thai Viet Jet Air again.

Delayed boarding, deboarding by bus - time to choose another airline.

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.
