Istanbul to Lahore flight was less than standard for international business class cabins. Seat did not were not flat and it did not operate easily. I had to push buttons hard repeatedly to operate the seat. I was in 5A seat

Istanbul to Lahore flight was less than standard for international business class cabins. Seat did not were not flat and it did not operate easily. I had to push buttons hard repeatedly to operate the seat. I was in 5A seat

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 🙏

Chicago to Istanbul was a much better experience than I expected since I’m more accustomed to Qatar Airways business class. The business lounge in the Istanbul airport was amazing - loved the lockers and phone charging stations, and the bathroom was a spa experience in itself. The onward leg from Istanbul to Karachi was utterly disappointing. Terrible plane, and I felt like I was in economy - the seats don’t come near to lying flat and the food was mediocre. What a sad downgrade - it isn’t as though the ticket on that leg was cheaper. So, on that front, there’s no contest with Qatar airways.

Second leg of Turkish Airline with Indigo is disaster for following reason. 1) You have to carry your cabin bags through ladder to boeing 777 because it was parked somewhere in parking lot and was not given a gate to board passengers and this seems to be people traveling to and fro from those flights and is not issue with flight itself. 2) I choose non vegetarian food on Turkish portal way ahead of checkin to entire trip, However the Indigo flight gave me random veg food saying they code veg food code from Turkish. 3) Indigo did not served any alcoholic beverages stating some weird reason which is non nonsensical. 4)Indigo have TV screens in front of you but it displays nothing except "Welcome Onboard" with annoying white black ground in dark flight. This is the most stupidest and annoying part because you are held hostage for 7 hours and only thing you could do is stare back at white screen which does not have entertainment package or even flight tracker. Such a shame.

During mid flight, try to get a flight attendant to help I couldn’t find one Otherwise, everything was perfect

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

7 stars hospitality and an excellent service by the Turkish Airline entire team. Somehow, our membership numbers for mileage points were not indicated on our boarding passes issued at O’Hare Airport by the Turkish Airlines check in desk. During transit in Istanbul, I brought to attention of customer service Turkish Airlines. Please have our mileage points posted to our membership account from O’Hare Chicago to Lahore for both my wife Kaukab Shirazi Thank you

Terrible boarding process, no proper line maintained even for business class, crews are not very attentive, business class food quality / variety / quantity have gone down, everything has become cheap.

Food quality and the overall service of the staff and significantly decreased. The flight was delayed at the Istanbul airport and the passengers were kept onboard for more than 3 hours. The staff didn’t kept the passengers informed and everyone was upset.

Turkish Airlines apparently no longer gives you 2 checked bags allowance on international flights, so that pleasure cost me $165 for my second suitcase at the airport. On top of that, they damaged that very suitcase, which happens to be a designer one and part of a set - ripped one of the four wheels right off.

It was okay. Mothers with rowdy children should be invited to sit in front of them.

Good food, overall very comfy. The flight was full so obviously not optimal, but it is what it is.

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

We missed our flight. There was not enough time built into the layover to get through immigration, customs, bagclaim, bag rechecking, and the long trip to another terminal and gate. Kayak really screwed up. We took the bus up to Wisconsin and then were picked up in Brookfield by private car. It was lucky we didnt miss the last bus out.

I tried both on line and by calling the Customer Service line to arrange for a special meal as i have food intolerances. I was under the impression from your service representative that I was successful. I was not. I cannot eat spicy foods and get very ill if i eat bell peppers. I could not eat either menu choice and no special meal was actually ordered. ( your representative tried to order it for a flight that did not have meal service!!! - found this out later). Your wonderful cabin crew managed to put together a fruit, salad, roll and cheese tray for me so I had something to eat. WHY WOULD YOU SERVE SPICY FOOD, WITH NO MILDER OPTION,ON AN INTERNATIONAL FLIGHT???

I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first

The plane was delayed by two hours in Chicago which led to us missing the next flight. Lufthansa rebooked the flight and booked us a hotel for the night in Frankfurt. The level of customer service and getting us taken care of was superb. The flight crew and the service on the ground was superb.

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious

I have flown with many airlines. My first time was several years ago. Now I remember why I avoided them for so long. Lufthanza is the only airline who has ever raised a size/weight issue with my modest standard size carry on. I had to repack three times to meet their carry-on weight criteria. (Apparently the rules of physics apply differently on Lufthansa flight than on other airlines.) In the meantime their staff was quite rude, repeating meaningless phrases like "Rules are Rules." And ignoring the additional fact that weight is also weight, whether it is in found in your carry on or in your suitcase. They eventually acknowledged that customer service and satisfaction is, for them, a low priority. Never choosing Lufthansa again.
