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

Service was very good, food and entertainment systems were good

The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

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

Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.

Airline should consider adding a small meal at the last leg of the flight, right now there is 7 hours of no meal break.

The food wasn’t good at all. I skipped meals .

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

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

As budget airline everything was good. Except that - boarding process can be more organised. Then if entertainment systems are not operational. Its better to keep them switch off.

Flight cancelled after 4+ hour delay. Indigo created a nightmare scenario and showed the most callus attitude towards the passengers I will refer to them was IndiNoGo!

Very nice and pleasant. Boarding was quick and the crew were responsive

Foreign nationals are not permitted to check in online in advance. We can only check in at the airport, so choice of seat was limited. I was stuck in a very uncomfortable location. I would expect a meal included in a flight of this duration. The food options to buy are very basic. IngiGo are a very good domestic carrier, but if they are serious about operating more international, longer haul flights, they need to improve this service to match every other airline I know.

All fine - you get what you pay for ! and it is a bargain

AirAsia kept us waiting for hours due to a technical issue with the plane, then eventually cancelled the flight. Unfortunately there is no-one to call or speak with at AirAsia, no customer service department at all, so I flew with another airline instead. Now I am going through the fun process of trying to get a refund from AirAsia. I strongly recommend that no-one flies with them, it's just not worth it.

The best part was Tony Fernandes actually reinstated the Buttercake menu. It has gone missing after Covid & i made a complaint in one of my Tweets back in October 2022. Both flight D170 & D171 landed very smoothly- kudos to both pilots!

The worst experience in any flight I have ever had, delayed for more than 10 hours, lost my other flight so I lost one day during my trip. Didn’t gave me facilities with my luggage either. Never again

I was next to a quite large person. Soni essentially had 2/3 of my seat for myself and couldn't sit properly. Even though there were some other seat available, the staff refuse that I occupy another seat.

Pros: The staff was very friendly. Cons: Long delay. The food is terrible.

I’m a frequent Traveler on all types of airlines, including budget. This was the worst flight experience I’ve ever had. Something was wrong with AirAsia’s systems and we were the whole flight was rescheduled to the following day, the third flight it happened to. Apart from an email which gave the new date the web and app said the original flight date which meant that there were hundreds of people queueing at the airport to try and find out what was going on. People waited six hours to talk to customer service who gave advice that didn’t match the web or app. Nightmare. just advertising for spending the extra hundred dollars I’ve ever seen.

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

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.

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.

Worst staff from Vienna. one of the server was very rude and annoying as she thinks she owns the airlines

Overall it was good. But air planes should be upgraded.

very run down aircraft. seat tilted. the mobile / magazine holder was broken. The entertainment screen was not working. The crew was good, polite and helpful
