the rudest staff in the world!!! we had overweight baggage, which is our fault but it is a really stupid rule, and the woman said we could reorganise or pay now, we said we’d reorganise and she started shouting “do it now! hurry up!” even though the flight wasn’t even boarding yet. She told us that if our two cabin bags were below 14 together, then we wouldn’t have to pay 500k dong. We reorganised and our bags were below 14kg. She then said that it was all of our bags together that should be less than 14kg. We were obviously confused by this, because she had just said that it was our two cabin bags and we asked her why she told us to rearrange our bags then. She started shouting at us again saying that we needed to “pay now or throw away”. We said fine, we’ll just pay, and she suddenly started asking for 1.51 million dong. I asked her why it was suddenly over three times the price and she said that it was always that price. I asked to see the other piece of paper she had that had the other price and she slammed her one on top of it and started shouting “pay now or i’ll close the gate” (boarding was already finishing at this point). So, we had no choice but to pay three times the original price, even though we reorganised our cabin bags to be under the necessary weight like she had asked us to. I wouldn’t even be so upset about the money if the staff were at least a little bit nice. She was possibly the rudest, most ignorant woman I have ever met in my life. Besides that, the plane/flight was just a bit worse than ryanair standard. Small seats, delayed by an hour. Typical low budget. At least the ryanair staff don’t try to scam you. Avoid at all costs, it’s not worth the hassle of dealing with such horrible people.

The boarding process took very long, partly due to passengers on incoming flight took too long to deplane

The flight left on time and landed early. The attendants were polite and friendly. Thank you

Not good in terms of amenities. For over 6 hours they don’t even provide complementary drinks or snacks-forget about dinner or lunch.

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

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

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

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!

I really like air Asia. The flights are running very professionally and both of my flights this last time got in early. Planes were clean. The staff was very professional and helpful. I understand they were supposed to be a budget airline but they don’t act like they’re a budget airline.

Flying from Koh Samui to Ha Noi with a layover in Bangkok. Vietjet cancelled flight. When I went to the counter they told me to call from r information. I asked for the number and they said they couldn’t give it to me. Be a little taken back I asked him to repeat that while I was recording on my iPhone. He told me that was unacceptable and called the airport police. I deleted the video but had to deal with a big hassle. Then booked with a different airline. Vietjet wouldn’t refund the ticket. Luckily Chase Sapphire didn’t have a problem with refunding me. Vietjet blows!

All good and friendly However the blasting of music at take of and landing is so annoying and can’t hear anyone speaking .

Terrible customer service. My last choice to fly now if there is no other options.

First time flying with VietJet Air is so so. Check-in process for domestic is okay and easy but during our flight back to Manila, the ground staff at Tan Son Nhat International Airport weighed our hand luggage before boarding when in fact, it should be weighed during the check-in process. They are very strict in terms of the 7kg hand carry it’s either you’ll pay extra, or leave things behind.

Waited for 1 hour on tarmac because they couldn’t locate a tow truck. Flight was fine once we eventually took off.

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.

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.

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
