The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Getting to the flight was arduous and lengthy. The flight itself was good but the food option wasn’t a good selection. I need to do a Kosher option on my return. Flight crew were nice

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

No lunch on a x-country flight scheduled for 10:50 am departure, arrived 5+ hrs later. That requires a black box label before you pay for the tickets. Worst, when I checked in online, it's specifically said that lunch was served on his flight for economy Plus passengers.

We had a lot of really rough weather but that was not Delta's fault. Pilot was amazing.

Flight was delayed for a hour from Warsaw, not sure why. When we landed in Chicago, plane was still on the runway for about half a hour. Took a while to get off.

No WiFi and ok comfort in business class. Home safe I guess that’s all that really matters.

Boarding was delayed for an unknown reason for more than an hour. While the airplane was at the gate, the boarding time was moved by 10-20 minutes every 15 minutes. No entertainment on the plane.

The flight itself was pleasant and on time. Crew was very good. However, breakfast food was barely acceptable. Unfortunately this satisfies the recent industry standards. I asked for a sandwich with ham (another choice was cheese), but received a sandwich with roast beef.

During the flight, the fleas biting me in the plane.

Delay rushed to the next plane and bags didn’t arrive in chicago

Boarding could've been improved a bit, the rest is excellent.

Agents helping disable person doesnt know connections to Poland and after 9 agents helping and 2hours ,we made it to proper terminal. Polish Dreamliner its Polish nightmare liner with so narrow seats and no room under front seat for bag and feet,in economy class.To upgrade, to higher standart cost an arm and leg ,even there are empty seats No good experience overall

The crew and flight were amazing . However , my bag’s locker got broken and no refund provided . Everything else was amazing except this bad incident that ruined my experience

Checking in took very long for whatever reason. Flight comfort these days is always poor so… Crew was great thought!

Overall it was good. Food was bad. I ordered gluten free vegetarian meal. But I got gluten free chicken for my long flight from Seattle to Istanbul. I don’t eat any kind of meat. Second meal I got eggplant with meat which I couldn’t eat. I don’t understand why we can’t get gluten free vegetarian meal for a 12 hour flight. I eat the bread and that was it.

As a big guy the seats are way too small for me. Would prefer more comfortable seats on these long haul flights.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

This is my 2nd time with the Turkish airline. Would definitely recommend. In stability we connected to Indiago would not recommend, very cramped seating. No inflight entertainment..service was inferior.

I wouldn't know what the flight was like. AI canceled my flight reservation!! There's no way to speak to an actual human to fix the issue! NEVER AGAIN! ALWAYS BOOK YOUR FLIGHT DIRECTLY WITH THE AIRLINE NEVER GO THROUGH KAYAK OR JUSTFLY.COM!!

Paying extra for premium seats was wasted. Turkish Airlines takes 2 seats for bassinet. The lady next to me had a baby with bassinet Bassinet was in front of my seat

Rude staff. I would avoid using the word racist but definitely partially or discriminatory. My 72 yrs old mother who is also disabled was traveling on this flight. She was the second passenger boarded to the plane. The First elderly couple ahead of my mother were allowed to use the airplane bathroom but my mother was denied entry stating it was for safety reasons. My mother objected the the couple in front of her were allowed but hostess still stated that due to the flight safety reasons she can’t use it. Even my mother explained that he is using blood pressure medication that’s why she have to use the restroom frequently but the crew continued arguing her. At one point the Mae attendent even suggested that if that’s the case my mother can urinate in her seat. The level of disrespect against an elderly lady is beyond my comprehension. This matter will be taken to the social media to shame the employees involved.

my experience was great with Turkish airlines . the problem i encountered was with kayak booking. When I booked . it showed that im allowed a bag . and when I got to the airport, i had to pay $165 for one bag.

Not up to Business Class standards. Two of the three toilets were out of order. The hostesses were aware and didn’t show any responsible act to do something. Food quality was not what we expect from Turkish hospitality. Overall we were not impressed and disappointed.

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…

Trip was smooth, good drew, average meal, almost cold coffee. Excellent landing. Did not enjoy going down the stairs, walking to the gate, walking up the stairs, going a long walk to the exchange gate, and going down the stairs again to be bussed all the way where we originally landed to take our next flight! Over all an average experience. Thank you.

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

No entertainment since it was a 3 hr flight. Good leg room for economy.

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.

They are professional. Nice crew. Still flying Boeing 747. Thank you for that. I love this airplane. Traditional.

Connecting from Germany with not enough time to go thru TSA and security so many times. Kayak or whomever doesn’t leave you enough time between flights. I made it with 5 min before my zone was called. Too stressful

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre

The flight was excellent in World Travellor plus. Well worth the extra money. Boarding at Phoenix was the usual poorly organized event. Very stressful.

Although business class, the seating was really cramped. The food was so so.

Smooth trip no turbulence which is always a bonus for me lol! In cattle class so an element of being a bit squished (but not as bad as other shorter haul airlines) smaller plane than the one we flew out on and entertainment system wasn’t as modern but still definitely passed the time. Lovely crew x

I was attacked in the Miami airport and the staff did nothing. On my flight from London to Miami one of the flight attendants screamed at me and demanded I keep my seat in the upright position at all times during the fight so the man behind me was comfortable for the flight. I will never in my life use British airways again

Airlines have to stop assuming passengers bring entertainment. Provide it like you used to in business class and above!! N

I don't know about the others but the flight attendant that took care of us had the absolute wrong approach "how do we dare asking for water or anything else for that matter"

Flying on the Boeing 787 from Seattle to London was everything that I expected. Every thing was great.

Not my definition of first class. No leg room and barely any recline. The food was good. The crew was great. The comfort for the price I paid for London to Cairo was highway robbery. The Wi-Fi didn't work for me either.

Seat pitch is not enough to eat comfortably. When seat in front is reclined, your screen comes closer to your face. Ryanair seats are actually more comfortable.
