Poor boarding and unboarding proceas. Multiple errors made by Singapore Airlines throughout the check in process.

On schedule, courteous, and efficient. Old aircraft with not so nice lavatories.

Food was excellent.. better if there are more movies selection.

Had picked seats while booking tickets but airlines reshuffled the seats without informing and we were again left with the worst possible seats on the return journey. terrible experience.

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.

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 .

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.

Crews were very caring and polite. Washroom was surprisingly clean. Overall experience was good , only food choices was very limited. Thanks

Food option Hindu veg to Hindu non veg request was unheard

Overall, very pleased with this flight. Boarding could be better because boarding was announced without a microphone so people didn’t know to line up until we heard the staff walking around to announce it. Also, had to stand in line for 10’ before we started moving. My husband who is impatient and cannot stand for too long did not like this. The rest of the flight- crew, food, and entertainment were very good.

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

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.

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 flight crew and attendants are very professional and polite.

Average, not more then that. Cannot compete with Singapore Airlines

No space in between the seats as per them the average height of human is 5’3” and weight as 55, so seats are designed as per the same. Also, the aircraft was dirty and full of insects

Technical problems checking in. Had to wait a long time while they got things ready.

Paid for the seat 17D. I found that that seat has no lean back facilities

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

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.

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.

The entire experience leave an impression that there are scopes for improvements in all spheres. Seems the airline has expanded beyond their capacity to manage.

Already mentioned the didorerly check in process. The crew were not aware that I pre-booked for snacks and paid for. They said I have to pay for snacks and drinks, when I showed the crew my boarding pass they said that the system was not updated with this information. Very strange excuse..

Cleanliness os Seats and surrounding areas. On time Departure and Arrival. No1 Budget Airline in India

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.

Our flight was delayed for about 3hours however the ground crew made it sure that we will not miss our connecting flight from Hanoi to incheon.

Flights on time is good. Crew should take care of passengers more.

No food? No movies? No water?? On an international flight, really???

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.

Trip was only 40 minutes in duration....no food and no entertainment. Otherwise it was excellent!

This was the worst flight (domestic or international) I have taken till date. Check-in and boarding experience at the airport were fine. I understand its a budget airline, still some basic stuff was missing. It's an international flight of almost 5 hours duration however, not even water was served to the passengers. If you need water, you have to go to the Crew Station and ask them for water. I asked him to fill up my own water bottle to which he denied and instead told me that I can have 1 Cup of water. When I informed, that we are total 4 family members needing water, he asked me to bring everyone to the Crew Station. Which I really don't understand. The cabin AC was not working or the temperature was kept at such a high temperature that I (and many others) were literally sweating. When I requested the cabin crew to reduce the temperature, my request was ignored twice. Finally I again had to go the front of the aircraft and ask the crew member to set it to 23. Then it was adjusted and we felt a little better. Overall a disappointing experience. They need to improve on lot of things while still keeping the cost low.

Maybe there was something wrong with pressure sensor or something. my ear was very uncomfortable and many babies were crying like hell. It happened during landing.

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.

The quality of service in AI Express was much better than Air India

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
