Airline reviews

I had the worst experience of my life in travel. Due to circumstances beyond my control (catastrophic traffic accidents on the highway between Gold Coast and Brisbane) I missed my flight for the first time ever. Because I booked through Kayak Singapore Airlines were not interested in helping me. They told me to contact the agent that I booked through. I was extremely stressed as I had connecting flights in Europe. First Kayak told me that the next available flights were in four days time. Then they told me that they could do it but at a cost of $2600 AUD. When I agreed he told me that he was having trouble getting it through Singapore’s system and he would contact me further once it had been done. When I had not heard from him after several hours, I phoned Kayak again, spoke to a different person who said he could do it for $8200. I declined and told him to cancel the booking. The worst part of this experience was that I had booked 5 flights altogether with Singapore including Premium Economy on two legs and Singapore cancelled all my flights including the return legs leaving me with having to completely reschedule my entire trip. Kayak refunded me $2000 from $5200, obviously leaving me out of pocket. This has left me feeling that I will never deal with Kayak or Singapore Airlines again.

Crew were so busy Anna so awesome. I was in a seat that got my food nearly last but the crew were Just awesome.

First time flying with Singapore airlines and I’ll give them two thumbs up 👍 👍

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

Headwind delayed our flight which wasn’t the airlines fault

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Food could have been better. Too many passengers getting up and down all the time.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

Could not really fault anything. We had a really short time between flights (about 45 mins), and had to get across the other side of the terminal. But we made it and crew were helpful. Food was good and service for the kids was great.

Sleep pods in SilverKris lounge are disappointing, showers are great though. Food decent, not amazing. Need more toilets in lounge ideally. Flight was good but service can be better.

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.

Boarding and deviating was mediocre. At boarding they have not prioritized Business class. During debarking they prioritized premium economy. Also bus rides both times.

The vietnam airlines app was not able to allow checkin with the confirmation nor with the ticket number. This led to quite a bit of consternation. Speaking with a colleague from Hanoi, he did tell me that their app is not the best. It may be best to inform travelers to only use the link and to plan on checking in at the airport for this airline. The check-in was very easy and the staff were excellent.

flight departure was late, with no updates on status of departure

The aircraft was little tired but the food and service was outstanding

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.

We flew with their partner VESCO on a small plane, it was a really good flight. There was no food or entertainment as it’s a one hour hopper flight.

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 most attentive crew and although we were a little late leaving ( missing passenger) flight experience more than compensated . Best flight attendants I have flown with in 50 years !!

Seats not comfortable. We had requested vegan meal and it wasn’t given.

Poor seats. Not helpful crew. The food was awful.overall very very bad experience. Traveled with the family of 5

I was denied boarding at the Brisbane airport and it seems like I won’t get any refunds from the airline

The connection between LA and Atlanta was too much stress

The airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.

The flight was delayed hours and most flights from CS are always delayed. Plane was efficient and got us home but not the best food and no entertainment system at all.

We were diverted to Chengdu, because of bad weather and finally made it to Chong King about 7 hours later

Food was terrible. Fish was equal to a sausage and scrumbled eggs were terribly green with a quite weird fllavour. Everybody with me hated all options. The best food was the bread with butter.

During flight, some passengers perform stomping leg exercises which disturb the comfort (I.e. sleep) of other passengers.

The food was perfect. The boarding process is a bit long. Given the late boarding time, I felt very tired by the time I was seated.

Delayed 50 mins. Check in was excellent, boarding was good, everything else was OK and perfectly acceptable for a budget airline. Price was excellent. I noticed this airline had two other flights to our destination cancelled so not very reliable.

Jane at Sydney International airport check in was amazing. She set up the whole experience to be a positive one.

The issue was a 4 hour delay to takeoff with very sketchy information provided about the available of the flights delay. Passengers were not informed of gate changes and how long the delay might be. It ended with a late night 2 hour drive to our home which was not ideal for elderly people.

Flight was fine with boarding starting a few minutes early. Not a fan of the crew pushing political messaging regarding indigenous naming of Brisbane city… really pushed it like I haven’t heard on Jetstar before.

Flight was delayed more than 1.5 hours. Gate changed multiple times

no announcement about why we where delayed which is very poor

It is what it is - nothing more, nothing less. No entertainment onboard but one kinda knows that when buying a ticket on a no frills airline. I choose Jetstar only because of price.

Plane was delayed both on arrival to Sydney and departure. We boarded the plane while it was in the process of being refuelled, which I am certain is against CASA regulations. Comfort for anyone over 6 foot is non existent.

Online checkin was a nightmare. They kept popping me into Chinese language site which I can't understand.

The flight take-off was delayed which was fine but the staff seemed pretty over their jobs. The seats are very uncomfortable and the food was pretty average. Overall is was okay.

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!

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

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.

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.

I was unable to check in online so had to line up at the airport. When I got to the counter? The staff told me I had to check my carry on luggage, which cost $70. When I boarded the plane, I saw many suitcases that were bigger and heavier than my carry on… so not sure how they were able to bring them on and I wasn’t …

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.

The flight was OK, but you need to warn passengers going to Vietnam that the full first, middle and last name needs to be in the issued visa, At least 5 passengers on that pane did not have that. We all had to pay $298 each to some agent to amend the visa. At least one lady could not and was left behind.

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
