You have to prepare for the waiting time for immigration to Vietnam, it takes 3 hrs to go thru and it is easy to get mad of it

We spent our long layover in the transit hotel in terminal 1 of Incheon Airport. The room was small, but was also very clean and well kept. I'd highly recommend this hotel if you have a long layover. The price wasn't bad at all.

For budget airline, it’s not bad at all. It’s definitely value for money. I added on the priority check in and eSIM. It’s well worth it.

For budget airline, it’s not bad at all. It’s definitely value for money. I added on the priority check in and eSIM. It’s well worth it.

Late departure, late arrival, and personal items on laps during takeoff and landing. Departure gate opened on time, but no direction as to whether to board at front or rear of plane based on seat number. Fashionable staff with sunglasses inside the plane and cockpit remained for ten minutes after the boarding complete announcement. For a scheduled 80 minute flight, adjusted to 65 minute as noted on takeoff; the total time on the plane with delays was r more than two hours. No confidence had there been an emergency that anyone would have been able or aware of what to do.

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.

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

VietJet was 2 hours late, but Kayak is not able to track my travel correct.

Very bad experience and will never try their service again. Not even water serve for 8hr flight. Will have to wait for every prepurched to cimplete before can buy water.

They do not even give you water. Have to pay for that and not cheap. Staff had some friendly and some very unfriendly. Terrible experience

I wasn’t able checkin on line so wasn’t given option buy food so I had to site watch everyone eat when I was hungry. That’s F-up

The actual flight was ok, everything else terrible worst airline in South East Asia, delayed twice and eventually took off late again, waiting in room at gate before flight no staff there no information about second delay, jammed on bus with doors closed waiting to be taken to the plane, just a disgusting airline, do not ever rely on this Vietjet will always cancel or delay your flight, and it’s not cheap when you see luggage price and other add ons, if possible try to book a better airline Bamboo air etc

No in flight entertainment, no food, not even drinking water, uncleaned flights, smelly bathrooms, and above all no baggage allowance, they charged us 53700 yen for the baggages.
