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!

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

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

Very hard seats. No food service, even though price is not competitive.

Boarding is becoming a hassle with Indigo nowadays, particularly if you are placed towards the front. The overhead luggage trays are either packed with flight equipments or already loaded by other passengers. So, if you are on front rows, your luggage may eventually end up towards middle. Food quality is going down by day. The only good element of being on time is also shaky nowadays.

Try to Fly on time without keeping commercial passengers stranded

No comments on food as I did not order. A normal Indigo flight was made memorable by the staff

Not much food options, entertainment, crew just ignores your request. The crew is not trained at all at hospitality. No wonder why people talk rudely to Indigo crew.

Standard Air India quality service. Nothing out of the ordinary. Exactly what anyone wants : efficient, polite, and gracious service; a comfortable seat; and on-time service

Flight was delayed almost 4 hours departing Goa. Even on arrival, there were busses to carry passengers to the terminal which were very delayed. All in all, an unpleasant experience.

The flight was cancelled and no support was offered and the rescheduled flight had several delays!! Terrible experience!

The crew was polite. The snacks were served cold and were tasteless.

Absolutely ignorant Air India personnel at the Air India counters in Cochin Airport.

When landing in Hyderabad, the pilot made a hard landing. Everyone in the plane were shocked. The captain landed the plane hard and felt as if we were going to be thrown out from our seats. It was surprising the captain didn't apologize or make an announcement about. Again a surprise no crew acknowledge this. This was an odd experience!

Uneventful trip. Good flight crew. Food could have been better and a bit more of it. Cabin cleanliness was ok.

The trip with Air India was better than expected starting with the check-in and the Lounge. The flight was comfortable for a 1 hour flight.

Bathrooms were horrible and no cleaning. Announced baggage claim carousel as one but came to a different one. People were waiting

I liked the timing but rest all were bad like below: 1. No restroom and food in waiting area at gate before boarding the flight. There was 2nd security scan at gate C2 and if someone goes to restroom which was outside that gate have to again go through security. So not having restroom, water in waiting area I felt is a blunder. 2. Entertainment system was not working for many passengers including mine. Crew members told about issue not fixed on time hence 16+ hours was tough to spend. 3. Food in domestic Air India flight was better but in international flight it’s not good.

I would love if the ground crew would be vocal about how they are boarding the aircraft. It seems chaotic.

Food too spicy for non Indians. Not enough food options were available for the passengers sitting towards the end. They should rotate serving people from the back as well not always from the front.

Very nice flight. On time, VERY comfortable seats. Complimentary food served. Would do again!

The audio earbuds was awful. The sound reproduction and fit was bad

Crew, the entertainment system and seats were in non functional
