Delightful...I have flown many millions of miles, this was a treat!

Delightful...I have flown many millions of miles, this was a treat!

ОК. However no USB jack for recharging devices. Multimedia not work approximately for 1/3 seats.

Waited too long in the bus to board the plane. Communication was non existence.

I had 2 flights on the same day ( beautiful sunny non windy day)both had a touch and go -around on the runway. My husband said they were training a co pilot. The bathrooms were stinky dirty and the the floor was sticky. On one flight I had the worst food option I have ever had on an overseas flight.

Entertainment system is okay, flight attendants were ok. Leg space very narrow, I couldn’t get what I wanted to eat, dinner nor breakfast.

Staff are friendly and the pilot when we landed very smooth.

Turkish Airlines made a long flight from YVR to IST a great flying experience. From the attendants, to the food, to the entertainment program to all the extras, a twelve hour flight ‘flew by’. Late departure and arrival was not the airline’s fault.

Excellent experience with business class area. Staff was attentive and food was amazing. Only one bathroom for business class which was logistically difficult for the staff while preparing meals. Need to offer fluids with meals. I did not get enough water to drink. But overall I rate it 5 star.

On time. Great service, friendly crew. Great food. Everything went without a hitch. We will not hesitate to fly Turkish Airlines again.

It was great. The service was excellent and the timing was very good.

On time, great food, good drink selection! Only down was alcohol-free lounge. Lufthansa had a much better offering!

Seat assignments for family traveling with 2 children. Loud crowd during sleep time

It was crowded… the bathrooms dirty and smelly. The seats have been made even smaller.

Kuwait Airways is one of the airlines that has entered into competition with other carriers and has become distinguished in the quality of its services. However, it still requires further development, particularly in its digital services related to airport operations and in-flight entertainment. I believe that over the coming years, Kuwait Airways may reach a highly competitive level in terms of the services it provides.

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??????

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.

The onboarding was extremely confusing. Had to climb the stairs to plan from tarmac with carryon bags in hand. No apologies for inconvenience. Overall not quite pleasant experience.

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 .

Food was not available in the middle of the trip that is 13 hours

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.

Beautiful Flight took off on time and everything was good

It was a horrible experience that I hope not to try it again. Rude stuff Poor food Always delayed schedules Lost baggages

Friendly staff from check in until the crew very helpful and smooth

Departed late Arrived about 40 minutes late The plane parked at the domestic terminal requiring transfer back to international arrivals

Very bad no tv no water no food absolute pathetic ! Couldn’t take zam zam ! No free zam zam water allowance! Dont travel

Poor airlines no infotainment system no food not even water was offered… absolutely not recommended! Nasmiles was not counted couldnt log in flynas app ! The app doesnt work with booking PNR! Please dont fly on these pathetic budget airlines!

Overall a poor experience…. No infotainment system no charging port no food was offered! Not recommended

It was hot inside as the air conditioner was not working and the crew members were not courteous

the seat you book will always be taken by someone else..…

Nothing The flight delayed for more than 3 hours as usual

In the future, it is preferable to provide free snacks

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

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.

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

The flight was delayed by 3 hours, causing me to miss my connecting international flight. I then had to wait in the airport 18 hours for the next flight. The reason for the delay was a computer issue, not something outside of their control like weather. To add insult to injury, instead of trying to expedite the flight to make up for lost time, they ran a carry-on baggage check to verify every bag onboard belonged to someone on the plane, which took another 20 minutes.

झूठा है इंडिगो फ्लाइट में मील दिया नहीं जब शिकायत किया तो बोला आपको मिल चुका है

It took a lot of time to declare that the flight gonna be cancelled ☹️ very disappointed.
