No entertainment u less you pay. Wish there were some free movies

Staff were friendly, and provided great service. The food was plentiful and delicious. Food could have been hotter.

I was traveling business purposes and I only had one carry on and a personal computer back pack . My carry on was 8.5 kg little more than allowable. At jfk airport check in they did not let me carry it . I was little disappointed.

More leg room and comfortable seats at least for long flights

The entertainment selections are amazing. But the live TV is sometimes spotty. If you’re going to have it, then have it. If you can’t make it consistent, then, perhaps it’s better not to have it. The crew are always cordial when approached, but they seem to do the minimum and sit around, talking to each other in the back of the plane during the flight. I realize that delays are not always predictable, but I missed my flight in Dubai because we left 90 minutes late from Washington. I will say that Emirates took very good care of me in Dubai. But I would rather not be delayed.

Probably the best flight I’ve ever been on. Emirates first class is leagues beyond British airways and Lufthansa’s.

Great flight. Comfortable seats, courteous service, and excellent selection for entertainment.

Serving food took so long . Almost time close to lend. Plus during landing air pressure in cabin cuss ear blocked took long time to unblock.

Emirates is usually on time, but not this trip. Also, during the flight the attendants disappear unless called upon. Very strange. I have watched the quality of Emirates service diminish over the last five years.

Food was not great. Crew members were created hassle with attitude at the gates and wasted my valuable time. I have been traveling in Emirates airlines many times. Over all not happy flying in Emirates airlines this time. Seats are very small and not comfortable. Seats looks like very very old and congested. It would be nice if they fix these kind of issues. I hope my next trip will be hassle free and comfortable journey in Emirates airlines. Thank you.

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

It was good no problems made it on time for the next flight overseas!

The made us waiting and held our passports and boarding pass making us miss our flights

Not impressed. Only allowed one carry on on such a long flight.

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

Bad experience with the delay n long wait time for connecting flight after missing the connection flight from Doha.

Wore experience due to delay and took me 3 days to reach my destination.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

Excellent will be flying again in May with Qatar. to Botswana.

Ultimate customer care humble and excellent service oriented crew , perfect timing maintained by the crew . My profound appreciation.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

On line check in needs a lot of improvement. I tried and gave up.

Food not good, flight attendants not the best, not accommodating very ruff

the female flight attendant was racist towards me. I could tell she treated the two other passengers next to me with more softness.

Oh my god! For an13 hour flight they serve you food just one time. Also don’t be thirsty they give you a little small cup of soda to drink. They seem like their goal is to feed you one so they don’t have to be bothered with you. It quite surprise for such a long flight there are several times to eat at least three and the food was well lackluster. The food and lack of offering drinks which were always hot no ice provided.

We were traveling first class. Checkin counter lady and her manager, both were in bad mood and did not treat us well about checking in the handbag. The gate agent took care of it right away. I travel Turkish twice a year in first class. No one has ever refused to check in the hand bag. Not sure, why this agent and her manager refused. Everything else was excellent.

The 787 economy was a disaster for long haul. The space was too little compared to 777 or 747. Also the extremely low tray table behind the seat made any dining effort a nightmare. However, the movies were up to date, and the food taste was good, despite of terrible serving process caused by small space.

A little bit more comfort. It’s tight space around the seats. But all else is great and a smooth flight!

0ur assigned seats were given to other individuals when we boarded the plane. We were given new boarding passes with new seats all the way at the back of the plane. The reason given to us was that there were issues with the seats. We found out that there were no issues, and someone else's were seated on those.

As usual invariably delayed Lots of time in getting chkd in baggage

Staff needs to be trained in managing customers better. Indigo appears to be a low cost airlines in all aspects.

Flight was delayed and also lots of mosquitoes on the flight

Two times the gate was changed and flight got delayed

INDIGO Never On Time & Always Prefer to Shuttle Passengers Like shuttle Corks

I did not like the communication gap existing amongst the staff and the customer. My flight to Nagpur was delayed by two and half hours but it was informed to me on email ( not by W.A. or SMS) when I have already left my home in Baner area. I was painfully detained at airport with luggage when the gate no. 10 was changed to 5. I'll never recommend your flight to anybody.

Seats don't recline, no charging points. New aircraft and very clean. Crew should serve some water atleast.

Wife and I were seated in separate seats across the aisle

There was inordinate delay without any plausible reason. This has become a normal feature of Indigo now a days.

Flight was inordinately delayed, which has become normal with Indigo. Crews were inattentive. After landing there was a lot of time for arrival of chek in baggage

It would have been perfect if there was onboard entertainment.

Food was unfit even for prisoners. larger front seats are terribly uncomfortable, which is ironic. Thorough need to upgrade aircraft on such a long route.

Food could be better they need a better caterer in DC flight from India always has better food

Everything! To start with, seats, food tray table, entertainment console all are broken! Imposing duty free baggage fees for $250 as a surprise penalty cannot be appreciated! Airlines should be responsible for transferring the checked baggages to the connecting flight. Having customer go through the transfer is painful considering the travel tiredness! No soft drinks served on flight is another crumble!

Old creaky plane, poor entertainment, USB port did not work. Food was ok.

Old fittings. Went business class. Staff not very considerate regards comfort.

Very old plane. Broken tray tables n seats. Entertainment system super slow to operate and very little content.

Service was good, crew response was prompt. The baked fish and Malay fish as well as the sauces with them were bland.

Screen are not working. Windows not clean. Staff is very good. Food is okay. Experience is good. I hope the up coming is more then betters for others airlines thank you.

Flight got delayed by 3 hours but no compensation or anything
