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 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

A 16 hour flight from Singapore to Los Angeles had only 2 meals. It would be great to have 3 meals.

Good airlines, travelled 🧳 n Singapore multiple times and experience is consistent

The flight was very late, sitting on the plane for over an hour and missed our connecting flight from Singapore to LA. As senior citizens, we were rerouted to Copenhagen and then to LA. They should not do this to senior citizens. They should have given us a hotel voucher for a night, then catch a flight to LA the next day. Singapore Airlines should grant us some kind of credit for the next trip, if they want us to fly with them. I doubt if we will ever hear from them.

The premium economy seats were not that great. It could have been more premium than economy seats.

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.

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

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.

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.

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.
