Flight was great. Smooth flying, movies good. Open seats allowed for good stretching.

Flight was great. Smooth flying, movies good. Open seats allowed for good stretching.

Smooth flight with enough time for connection. Ran out of meal options. In-flight and gate staff were friendly and helpful. Good service overall.

Not enough veg food for passengers. I actually did not get veg food and starved the entire flight duration.

The flight was ok, but the chargers did not work, and the speakers in the back of the cabin did not either. The seats are too small, and the food was terrible. However, I am writing because the crew was extremely rude, not only that, but they also kept the curtains closed, forgot to clear our trays, the bathrooms were filthy, and trash was piling up. Additionally, one of the attendants had her earbuds on while in the cabin. From the movement, it seemed like she was listening to music, so not even the safety aspect was there. My neighbor s English is not good and they were very dismissive of her. When we deplaned, the crew in the back was just chatting with one another, and the first class attendant was nice and said thank you. It is nice that the crew gets along so well, but they did not take care of the passengers at all. They rushed through all the services and otherwise did not go through the cabin to offer water or anything else. i had the feeling of being unwelcome at a party. I am not a grumpy traveller, but I thought you really needed to know. Thank you, Carin

Crew was very courteous, friendly and professional. Caring and attentive.

Very good experience. All of the details made this experience very positive.

Cheapest airlines I have ever been on. I got downgraded and never got on united. I got rerouted through Vancouver onto jetwesf

The crew was exceptionally polite and caring. The plane was comfortable. Great experience. Will fly more on Air India because of this experience.

The flight attendants were rude in the DEL to FRA flight. The transfer between the two flights at Frankfurt International Airport was an unpleasant experience. The airplane was never parked at the terminal, but was deboarded instead on the tarmac itself. For those passengers in need of a wheelchair, it was a nightmare to come down the stairs and then rush across the airport to catch the connecting flight from FRA to IAH. Upon arriving at IAH, it was informed that the luggage had not arrived. Would make it a point never to travel with Lufthansa again.

Entertainment system is old, touch screen isn’t working properly. New movies should be added atleast once a month Should provide toothbrush and toothpaste at least when asked.

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.

IndiGo is low cost and therefore no frills, but is always a pleasant experience. No mood lighting and fancy features but clean aircraft, professional crew and absolute value for money.

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

Very hard seats for long flights. No food even on International flight. Won't fly Indigo again if I can help it.

Terrible experience at IST airport due to mismanagement by ground and wheelchair staff.

Some seats don’t recline. No USB port or power outlet, no inflight WIFI - not even for SMS/Messaging apps. Ontime performance was very good. They should have at least one crew member who speaks the local language, for flights like these.

Although we took the XL seats with more width, we found that you do not have a seat in front to stow your personal item, nor can you stretch your legs. This is not the best option for a comfortable seat. Boarding was timely but disorganized without any row based entry.
