Very Bad experience bqz I was missed my next flight.

Awful experience in Indigo, check in lines were very long with inadequate staffing. Had to wait in a warm stuffy plane on the tarmac as the flight was delayed.

Horrible, hated every part of it. They do not have business class- just tried to make one row. Boarding was a mess- felt like hungry people fighting for food. Will never ever travel in Indigo

It was great! Great value for the price I paid. Great crew and great food in business class

The flight starts at 7am from New Delhi, a supremely inconvenient time, especially, if you are coming from another smaller city. Please consider moving it to 4am or 5am.

Business class: Like: food selection presentation Staff on the airline Love: lounge in Istanbul Needs major improvement: attitude of reception at Istanbul lounge: 4 of them sitting there: inattentive and then rude. They do not fit with rest of Turkish hospitality!

Crew was good. Plane and seats were cleaned and good. Food and entertainment system was bad.

COmpared to my experience in the business class of other airlines the food variety and offerings were meager. They did not have any cookies or crackers for snacking! They were unable to offer some other items. This has never been my experience in other airlines.

Service for wheelchair person is very poor. No display at exit door from Delhi to Istanbul airport, so you cannot decide where to go, and the helper for wheelchair person asked $10.00 american money, when I said you should not charge or I asked him to take indian money. He said he needs only American dollars and bring me back and dropped me at the same exit door helplessly. I felt bad very much but was helpless. And ranaway. I was to take his picture to post it on the website. So many passengers were waiting for the help, ultimately one buggy came and helped the passengers and the driver did not ask any money. Please let the air authorites know the incident.

I asked for blanket extra because I got cold. No body came back. I asked for chai it was not good. Sorry to say.

I do not have any issue after travelling but not able to return back to Newyork because my flight is cancelled. Requested to refund my full amount.

Are you KIDDING RIGHT NOW?!?! SENDING OUT SURVEYS FOR CANCELED FLIGHTS IN A CONFLICT ZONE?!?! ARE YOU FEELING OK??????

Food is terrible, service is not good. Staff were not personable and rushed food service.

Boarding /lounge :Chaotic boarding , business /first class had a dedicated line but it was upto to the passenger to figure out and use those lines .Oasis lounge is clean but tiny so it felt over crowded . Neither the food nor amenities felt business/first class . Cabin and tech : 2-2-2 configuration needs to go . Leg space is cramped , headsets didn’t work . WIFI does exist or didn’t work on the entire 20 hour journey . Food and crew : Preordered “Hindu Non vegetarian” meal , crew was clueless , they didn’t even bother to ask if they weren’t sure what that meant . Served mediocre vegetarian food though menu had chicken /lamb options . In short , worst business class experience of all the airlines I flew to date . Not sure if there is one area they compete in let alone excel … avoid if you can .

Everything was good and no points to complain. Food is always a tricky concept. Sometimes you like it and sometimes you don’t. Food was redundant from Kuwait City to NY-JFK.

Comfortable seats. Be aware there is no alcohol on this airline.

Seats were comfortable. Be aware there is no alcohol on this airline.

It was very nice flight only suggestions to upload recent videos and English subtitles. Thanks

Wheelchair service is not available right away on Kuwait Airways

Not much on entertainment, food was good but not delicious, flight was on time

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

Screens should work, Seating need to be comfortable, Luggage management was worse. Took 2 hours to get my luggage

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..
