Turkish Airlines was great. My new layover was over 18 hours due to inclement weather back home in Washington DC and the airlines provided me with a hotel room and dinner voucher during my layover

Bad sitting every flight not good experience with food either

My, Syed Zawar Hussein Shirazi frequently flyer membership number was not included on my boarding pass from O’Hare to Istanbul despite my reminder to the attendant at check in. Further she forgot to give me my boarding pass form Istanbul to Lahore and she needs to improve her customer service, please 🙏

Everything about that day was great I was happy with how things went as a first time traveling with the airline thank you for all that you’ve doing by taking us there to our various destinations thanks.

The seats were extremely small. Boarding was not communicated correctly. It wasn’t a pleasant trip.

I am always amazed with the great service they offer on their regional and international flights

Nothing luxury about Turkish airline compared to many other airlines

Entertainment was good. Flight was delayed, nearly missed my connecting flight. The gate was changed on several occasions. My luggage did not arrive on time and had to leave without it.

Service was slow and checked bag was off last evening when flying business

Everything was good except that they didn’t give us seat for our connecting flight in Istanbul from Cairo. This created a panic situation. Hopefully they give all customers connecting flights seats right from the start.

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.

They denied my meal which was included in ticket and also damaged my bag completely and broke the wheel and still not accepting their fault

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.
