Limited food options. I dont like chicken or even fish but that’s the only option. Sad to say not impress

Limited food options. I dont like chicken or even fish but that’s the only option. Sad to say not impress

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

Kayak really screwed up by offloading the booking to a third party. They were completely inept and caused a bunch of toil. I will never use Kayak again.

A little more room from the reclining seat in the front of me.

It was okay. I feel that Singapore Airlines isn't as good as it used to be but it's still not bad

Overall the airline tried to give excellent service. The wheelchair service was bad at SFO. My baggage was also delayed but I thank them for taking the trouble to find it and deliver it to my home.

Overall were very good and I was satisfied w/ all the food and services.

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

Pleasant business class flight experience with good onboarding experience. Flight service team was excellent with usual book-the-chef menu available

I thought I already provided this feedback. 12 hours with no wifi is unacceptable. Lay flat is nice but a bit cramped.

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

It was ok, it felt more like an internal flight than an international flight so I guess expected a slightly better standard. Nothing really wrong with it but there was no inflight entertainment. Food and service was good.

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.

This is a very short commuter flight, so there is no food or flight entertainment. Hence, I marked it in the neutral flight left on time. The plane was full pretty much and it was a pretty easy flight overall very good.

Flight was short but turbulent giving uneasy feeling :( ; although views were mesmerising ;)

Flight boarding experience with journey was smooth; can describe it as a less to minimal turbulent flight!

I paid 675£ for LHR-BOM-BKK (return flight). They charged so much money but provide very less food/drinks as compared to another airlines. Never ever fly with Indigo.

Just fly from point a to b. rest holds zero stars. And with zero competition, what do you expcect

Flight was delayed 110 mins.. Crew on Ground or in Air had no regrets.. No apologies... Very poor boarding process... Awful food and beverage choice.

Flight was delayed and due to this we almost miss the connection flight

The flight was delayed by 3 hours, causing me to miss my connecting international flight. I then had to wait in the airport 18 hours for the next flight. The reason for the delay was a computer issue, not something outside of their control like weather. To add insult to injury, instead of trying to expedite the flight to make up for lost time, they ran a carry-on baggage check to verify every bag onboard belonged to someone on the plane, which took another 20 minutes.

झूठा है इंडिगो फ्लाइट में मील दिया नहीं जब शिकायत किया तो बोला आपको मिल चुका है

It took a lot of time to declare that the flight gonna be cancelled ☹️ very disappointed.

They denied my meal which was included in ticket and also damaged my bag completely and broke the wheel and still not accepting their fault

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.

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.

I appreciated a meal on the shorter flight. It was slightly delayed with no announcement but I was able to determine what was happening.

Really old air craft, broken seats and tray tables. Entertainment screens don’t work. Charging ports didn’t work.

seats were not comfortable, entertainment was not working and food could be much better, given the airline calls itself full service and india's flag carrier.

Terrible airline... Originally, the flight was canceled and didn't receive a notification, had to learn from their twitter account... Rebooking was a huge pain... Every other airline like American and United did eventually fly a day later... The flight had a layover, no other airline needed one... India is such a weak nation globally, this airline has no leverage to negotiate good airspace... Flight left late, again no notifications as to why at the airport. On the plane, wifi is spotty, chargers don't work... The only saving grace used to be good food. Even that has gone down the drain. Just the worst!

The flight was on time, the entire experience was very smooth. The Flight crew were incredibly professional and nice. Made us feel very comfortable

Flight has no entertainment. Crew doesn't care atall. Horrible service and never going to take Air india and will spread their Horrible service.

Very bad experience luggage never made to destination no help form airlines staff aircraft was old crappy forts staff service bad airlines staff

The boarding experience was very organized and easy to follow. The flight was pleasant and the food provided was also very good. Both Delhi and Mumbai airport have metro connections which make getting around much easier.

Undisputed leader in sky for Indians. Very good crew right from ground to mid sky. Very sumptuous meals twice

I reached the check in counter 1 hour before take off and was denied boarding because the luggage could no longer be transferred to the flight. I was aback when throughout the world(including India) for a domestic flight, you need to report 1 hour before boarding. Then on top of that i was made to buy a brand new ticket. I had paid $350 for a business ticket between delhi and mumbai and then was made to buy another economy ticket for $100, No concessions/discounts were made for the airline's own inefficiency! The reservation counter was also extremely rude and unapologetic about making me pay a second time. For such a mediocre airline, there seems to be zero focus on providing good service to their customers and providing a pleasant experience.
